[00:00:51] <Jymmmmmmm> I fI was able to get my hands on some linear scales, could they be connected to emc in a way to provide feedback simular to what rotary encoders would do?
[00:01:25] <Skullworks_PGAB> that don't work well
[00:01:53] <Skullworks_PGAB> but they do use liner scales as a second feedback
[00:02:21] <Skullworks_PGAB> to offset thermal growth etc.
[00:03:37] <Jymmmmmmm> why not? just curious
[00:03:55] <Skullworks_PGAB> Jym - why not just get some U.S. Digital E4P
[00:04:22] <Jymmmmmmm> that wouldn't tell me the position of the axis, would it?
[00:04:43] <Jymmmmmmm> between power cycles and such
[00:05:31] <Skullworks_PGAB> because the motor wil often sit there moving back and forth in a continuous "hunt" for the perfect position.
[00:05:43] <chr0n1c> add a 3 axis dro
[00:05:53] <chr0n1c> you could use it when the pwoer to the drives is off
[00:06:01] <chr0n1c> and some have serial outputs
[00:06:12] <chr0n1c> and or paralell outputs maybe?
[00:07:45] <Skullworks_PGAB> an E4P is a rotor encoder - with a 250 line disk - if this was on your stepper shaft you would read .00005"
[00:08:52] <Skullworks_PGAB> * Skullworks_PGAB bases that on a .2 pitch driven @ 1:2
[00:09:06] <Skullworks_PGAB> error - .0001" rez
[00:09:08] <Jymmmmmmm> Skullworks_PGAB: not to be a smartass, but what does an encoder REALLY do for me? Just accurately determine the amount of movement, not acutal position
[00:09:19] <Skullworks_PGAB> yes
[00:09:26] <Skullworks_PGAB> not true position
[00:09:39] <Jymmmmmmm> ok, I'm getting it now
[00:09:56] <Skullworks_PGAB> does not factor in backlash without software.
[00:10:32] <chr0n1c> does anyone know of a quick dirty schematic for 555 timer stepper control?
[00:10:34] <Jymmmmmmm> Yeah, and that's where I get kinda stuck.
[00:10:46] <chr0n1c> dial indicator
[00:11:03] <Skullworks_PGAB> YADRO
[00:11:04] <Jymmmmmmm> chr0n1c: and what is a TDI gonna do within emc?
[00:11:06] <chr0n1c> mounted on the table... touching the z axit
[00:11:28] <skunkworks> Jymmmmmmm: honestly - if you get the steppers working as they should - you will only loose posision in a crash.
[00:11:31] <chr0n1c> you put the numbers you get from the indicator into the ini file for the backlash comp?
[00:11:49] <chr0n1c> my home stays put even when i turn the machine off
[00:11:54] <Jymmmmmmm> chr0n1c: WITHIN emc, not external. I need a way to log movement to run long term tests as nothing is repeatable.
[00:11:58] <chr0n1c> as long as i home it before i shut down
[00:12:35] <Skullworks_PGAB> also an option - put the encoders on - and use the PICO USC to drive your stepper card
[00:12:52] <Jymmmmmmm> If I can't successful repeat an error over and over agian, I can't fix it.
[00:13:05] <Skullworks_PGAB> if the steppers loose steps the USC will spot the error on the feedback
[00:14:02] <Jymmmmmmm> See, were back where we started, just throwning money at it, but not knowing where the problem is.
[00:14:17] <Skullworks_PGAB> also - USC makes its own pulse stream, much more stable than the EMC software pulse stream
[00:15:05] <Skullworks_PGAB> which axis looses steps - or is it all?
[00:15:17] <Jymmmmmmm> X and sometimes Y
[00:15:22] <chr0n1c> it's free... i don't understand why you are trying to turn it into a caddilac...
[00:15:32] <chr0n1c> *not to be rude...
[00:15:58] <Jymmmmmmm> chr0n1c: backlash is the LEAST of my problems right now
[00:16:07] <Jymmmmmmm> it's stalling
[00:16:30] <Jymmmmmmm> and determining WHY it's stalling... motor, driver, PC HW, config, machine, etc
[00:17:26] <Skullworks_PGAB> have they had you back off on the accel rate?
[00:18:00] <Jymmmmmmm> No, but I did... from 20 to 15 right now. still playing
[00:18:15] <Skullworks_PGAB> inch per second per second
[00:18:38] <Jymmmmmmm> I have no idea what that means. Just changing settings in the ini
[00:18:56] <Skullworks_PGAB> rate of accel
[00:19:39] <Jymmmmmmm> I still dont know what that is. I know it's the rate at which the speed is changed.
[00:20:07] <Jymmmmmmm> laws of physics or cheap china steeprs
[00:20:25] <Skullworks_PGAB> * Skullworks_PGAB needs to log out and switch to a different system
[00:20:35] <Skullworks_PGAB> back in a few
[00:25:05] <skullworks-GAB2> now continuing the search for that vid - fired Up this WinBORG Xp game box and 2 more servers to search...
[00:25:24] <Jymmmmmmm> eeesh I can jog at 120IPM np
[00:25:51] <skullworks-GAB2> nice...
[00:26:14] <chr0n1c> i canonly jog at 10 ipm :(
[00:26:19] <Jymmmmmmm> hell, even made a diamond jogging
[00:26:28] <chr0n1c> is this a vid of your machine skullworks-GAB2?
[00:26:41] <skullworks-GAB2> no
[00:26:54] <skullworks-GAB2> I wish - kinda
[00:27:30] <skullworks-GAB2> it was built by a guy on the DIY-CNC forms
[00:27:48] <skullworks-GAB2> he is selling them as complete units
[00:28:02] <chr0n1c> hmm
[00:28:20] <skullworks-GAB2> but it is a great example of what CAN be done with small steppers
[00:28:35] <skullworks-GAB2> its SCARY fast
[00:28:37] <CIA-20> 03cradek 07TRUNK * 10emc2/nc_files/daisy.ngc: time-honored or silly: you decide
[00:28:54] <Jymmmmmmm> ok, I have to get to work in a bit, gonna shut things down for now on emc box
[00:29:43] <chr0n1c> google images search.. great for finding things to engrave
[00:36:28] <skullworks-GAB2> now I need to start checking USB drives...
[00:38:26] <Aver> Aver is now known as Rugludallur-NewB
[00:45:14] <chr0n1c> uh oh we lost a chicken nugget to the basement floor!
[00:48:03] <skullworks-GAB2> Ha!
[00:48:19] <skullworks-GAB2> being stubborn pays off
[00:48:29] <skullworks-GAB2> found the link to the site
[00:49:34] <chr0n1c> already?
[00:49:35] <chr0n1c> lol
[00:49:49] <skullworks-GAB2> http://romaxxcnc.com/Home.html
[00:49:53] <jepler> cradek: ooh you finished daisy?
[00:49:59] <cradek> yep
[00:50:20] <chr0n1c> a flower?
[00:50:28] <jepler> and ran it on max?
[00:50:30] <cradek> yes
[00:50:33] <cradek> runs great
[00:50:34] <chr0n1c> that's a pretty machine...
[00:50:53] <jepler> exciting
[00:51:54] <skullworks-GAB2> take a look at that drilling video
[00:52:59] <chr0n1c> i've drilled at amazing speeds with a pro tool n die machine
[00:53:04] <skullworks-GAB2> or the jog video
[00:53:33] <chr0n1c> i used to cut wood on my milltronics at about 60 or 70 ipms
[00:53:45] <skullworks-GAB2> that machine runs scary fast when you note the true scale
[00:53:57] <chr0n1c> yup...
[00:54:50] <chr0n1c> looks liek y is a belt drive...
[00:55:26] <chr0n1c> must be on some nice bearings...
[00:55:26] <skullworks-GAB2> Had a job for DEC (Digital Equip...) making some SCSi backplain adpator boards out of Lexan - was cutting at 300IPM at 12000rpm
[00:55:46] <skullworks-GAB2> skate bearings
[00:55:53] <skullworks-GAB2> 608zz
[00:56:15] <skullworks-GAB2> $20 for 50
[00:56:24] <chr0n1c> yeah i ordered some skate bearings.. for prototype slides and a spindle.. for the 24" x 48" incher i am building
[00:56:32] <skullworks-GAB2> uses LOTS of them
[00:57:08] <chr0n1c> i was thinking about 3 per... place wher ethe table mounts to the slide
[00:57:37] <chr0n1c> i only got 8.. to see what kinda quality they are
[00:58:03] <skullworks-GAB2> just be sure to include a method to adjust the gap
[00:58:14] <chr0n1c> i also though bout maybe some wheel bearings for cars... they are cheap(ish) and are built to last for a while
[00:58:35] <chr0n1c> would be good for a spinle i think anyways
[00:58:39] <chr0n1c> spindle
[01:01:06] <skullworks-GAB2> If I do the router thing - I'm going to dump the money for a good Maketa router - or many even a Porter cable.
[01:01:19] <skullworks-GAB2> but it won't be soon
[01:01:32] <skullworks-GAB2> no place for anything that size
[01:01:44] <chr0n1c> yeah i am running out of room in my house
[01:01:59] <chr0n1c> i'm going to have to trow some junk away to make room for the 24x48'er
[01:02:20] <skullworks-GAB2> as is I had them hold off shipping my IH mill till I get back from CA
[01:02:55] <skullworks-GAB2> so It should go on the truck about may 10th
[01:14:33] <chr0n1c> here goes a 54 minute engraving program on some acrylic... ran twice the second for a cleanup pass.. :|
[01:15:06] <chr0n1c> ...and iron cross, with a 3d skull in the middle of it...
[01:15:14] <chr0n1c> 2"x2"
[01:15:22] <skullworks-GAB2> you the the resistors to run on 12V?
[01:17:24] <chr0n1c> no..i was gonna get some when i was at mendelsons today i got all excited abotu the dual shaft stepper i found to replace my z...
[01:17:33] <chr0n1c> so i can set zero by hand and not with jogging
[01:18:04] <chr0n1c> and i got a 450 oz in slo syn 8 wire... already wired for unipolar
[01:18:14] <chr0n1c> for $16.10
[01:18:18] <chr0n1c> both*
[01:18:48] <skullworks-GAB2> round or sqr body?
[01:18:58] <chr0n1c> i'mmma put a handwheel on the z dual shaft.. flip the drive off.. set zero flip the drive back on
[01:19:01] <chr0n1c> round
[01:19:08] <chr0n1c> but it was only like 15 bux.. ;)
[01:19:15] <skullworks-GAB2> :(
[01:19:16] <chr0n1c> so no matter which type
[01:19:20] <chr0n1c> still a good deal
[01:19:29] <skullworks-GAB2> maybe
[01:19:55] <chr0n1c> they themselves are sellin them on ebay .. the same motro for 143 or something
[01:19:58] <chr0n1c> motor*
[01:20:26] <skullworks-GAB2> PT Barnum had a phrase about that...
[01:21:31] <skullworks-GAB2> ebay is such a success because there is always someone who will buy your junk
[01:22:41] <chr0n1c> lol
[01:22:51] <chr0n1c> i sel shit i find in dumpsters on there
[01:22:55] <chr0n1c> ;)
[01:22:58] <chr0n1c> i know what he means
[01:23:38] <chr0n1c> those crazy junk mongers!
[01:23:49] <skullworks-GAB2> I made a fortune dumpster diving after the 1984 Olympics
[01:24:54] <chr0n1c> i pulled about 3 grand in the last year... just part time after work.. in between people hanging out n partyin
[01:25:00] <chr0n1c> lol.. i got the party pad....
[01:25:11] <skullworks-GAB2> KABC was loading untouched pallets of cable and other hardware kept as emergency spares into pull off dumpsters
[01:25:14] <chr0n1c> my own house and i'm single...all my buddies hide from the gf's here
[01:25:21] <chr0n1c> so i get interrupted plenty
[01:25:51] <chr0n1c> i drag out copper wire of any kind every chance i can get
[01:25:56] <chr0n1c> i got one hell of a stash here
[01:26:03] <chr0n1c> i need to melt the palstic off it and cash in
[01:26:05] <skullworks-GAB2> sealed boxes of TRW and Beldon cable
[01:26:11] <chr0n1c> yum!
[01:27:21] <skullworks-GAB2> Sold it to some business that used that same catalog number for 20% bellow there best price and still made out like a bandit
[01:27:45] <chr0n1c> i should go out tonight.. but my car is making noises..
[01:27:52] <chr0n1c> bad wheel bearing or a bad cv joint
[01:27:59] <chr0n1c> either would be bad to break down at 2 am
[01:28:05] <chr0n1c> *behind a closed biddness
[01:28:06] <chr0n1c> lol
[01:28:19] <chr0n1c> the cops already are up my wazoo
[01:28:20] <skullworks-GAB2> my car makes noises too - attracks cops
[01:28:46] <chr0n1c> i usually drive around dayton till my car is packed with cool stuff then come home unload it
[01:29:02] <chr0n1c> take pics... put the cool stuff on ebay and keep a few things once in a while for myself
[01:29:14] <skullworks-GAB2> Mustang GT with Flowmasters.... I'll rattle your windows with out rap music...
[01:29:56] <cradek> man, one of those
[01:30:19] <skullworks-GAB2> I could have sold truckloads of PC's
[01:30:25] <cradek> I'd (silently) drive a circle around your car :-)
[01:30:43] <chr0n1c> ha...
[01:31:03] <chr0n1c> i got a 1990 lumina eurosport with 170,000 miles :(
[01:31:09] <chr0n1c> it still looks decent though
[01:31:19] <chr0n1c> but it showing its age mechanically
[01:31:48] <skullworks-GAB2> my friends computer shop tosses all PC's under 933 straight into the garbage - claims the labor cost to test them is more than there worth
[01:32:10] <chr0n1c> send me one!
[01:32:15] <chr0n1c> i'll pay shipping!
[01:32:33] <chr0n1c> hell send me two
[01:32:49] <skullworks-GAB2> I think I could send yoou a 333 for your existing box
[01:32:56] <chr0n1c> i used to have 5 pcs networked in my house.. they all slowly died one by one...
[01:33:07] <chr0n1c> i'm down to two now.. thisone and the emc box
[01:33:12] <skullworks-GAB2> Only 5?
[01:33:19] <chr0n1c> yeah only 5...
[01:33:19] <skullworks-GAB2> kidding
[01:33:35] <chr0n1c> i got 4 of them at a biddness auction.. for 4 bux.. monitors and all
[01:33:44] <chr0n1c> 40 bux.. oops*
[01:33:46] <chr0n1c> lil different
[01:33:56] <chr0n1c> it was a title agency
[01:34:11] <chr0n1c> something about getting shut down for scamming and money laundering?
[01:34:19] <skullworks-GAB2> got a pile of loose cpu's here
[01:34:31] <chr0n1c> got a 333 slot 1 p2?
[01:34:34] <skullworks-GAB2> few Athlon XP's
[01:34:40] <skullworks-GAB2> think so
[01:34:47] <chr0n1c> i'd have to check my mobo to see if it'll work...
[01:34:58] <skullworks-GAB2> I know it works
[01:35:01] <chr0n1c> it's gateway.. so.. who knows
[01:35:09] <chr0n1c> i mean to see if i can go to 333
[01:35:10] <skullworks-GAB2> <<< ex GTW tech support
[01:35:32] <chr0n1c> i got two 450 slot1's but no board to support them
[01:35:43] <chr0n1c> i think at least one is still ok
[01:35:54] <chr0n1c> one.. i over clocked to 733...
[01:35:59] <chr0n1c> it fired in 20 mins
[01:36:00] <skullworks-GAB2> got the serverence check and the T-shirts :)
[01:36:13] <chr0n1c> gotta love free thsirts
[01:36:36] <chr0n1c> fried*
[01:36:49] <chr0n1c> i am getting worse with the dyslexia thing i think when i type
[01:36:56] <skullworks-GAB2> loved the one I got - "I survived Y2K at GTW"
[01:36:58] <chr0n1c> it doesnt happen when i read or write
[01:37:27] <skullworks-GAB2> only took 2 calls that night
[01:37:29] <chr0n1c> maybe my 1 finger is getting longer...
[01:37:33] <chr0n1c> lol...
[01:37:40] <chr0n1c> the y2k was bogus
[01:37:59] <chr0n1c> it wasn't even the real year for the apocalypse...
[01:38:05] <chr0n1c> i heard...
[01:38:10] <chr0n1c> i'm no expert, lol
[01:38:28] <skullworks-GAB2> no - just there was sooo much hype the companies that knew they were going to have issues got them fixed well beforhand
[01:38:46] <chr0n1c> i never had anything go hokey then
[01:39:13] <chr0n1c> but.. i don't have 2 gb databeases either
[01:39:13] <skullworks-GAB2> but yeah - I should have a slot 1 pII-333 here
[01:39:28] <chr0n1c> right on...
[01:39:35] <chr0n1c> maybe i got somethin we could trade...
[01:39:39] <chr0n1c> need any pc parts?
[01:40:00] <skullworks-GAB2> and a few 450's - but thats a BX board and yours is an LX
[01:40:21] <skullworks-GAB2> I have PILES of PC parts
[01:40:41] <skullworks-GAB2> I would gladly give them away to good homes
[01:40:50] <chr0n1c> hmm...
[01:40:59] <chr0n1c> so you know about the gateway mobo's?
[01:41:12] <skullworks-GAB2> sure
[01:41:34] <chr0n1c> do they have jumpers or autodetect for the cpu's?
[01:41:39] <chr0n1c> mhz's*
[01:41:42] <skullworks-GAB2> up thru soc 423 p4
[01:41:53] <skullworks-GAB2> auto detect
[01:42:02] <chr0n1c> i can't see it....
[01:42:05] <skullworks-GAB2> for slot 1
[01:42:09] <chr0n1c> i got so much stuff shoved in that box
[01:42:25] <chr0n1c> i tore all the stupid plastic off... i gaind 8" more desk space, lol
[01:42:34] <skullworks-GAB2> only the early socket 7 boards required jumpers
[01:42:52] <skullworks-GAB2> and soc 8
[01:43:05] <skullworks-GAB2> if you had a Pent pro...
[01:44:23] <skullworks-GAB2> find the p/n of your board - should be a 4000xxx or AAXXXXXXXXXX
[01:44:47] <skullworks-GAB2> I can give you the entire lowdown
[01:45:47] <skullworks-GAB2> there is 1 important jumper - NVram clear
[01:46:05] <chr0n1c> i'm looking through gateway.com for the docs to this beast
[01:46:11] <chr0n1c> it's a g6-233
[01:46:18] <chr0n1c> i think the ram is maxed out at 384
[01:46:25] <chr0n1c> and i got that in it now
[01:46:35] <skullworks-GAB2> if things doint PnP properly clearing the BIOS will help things detect
[01:46:45] <skullworks-GAB2> yep - 384 is mx
[01:46:48] <chr0n1c> or maybe not.. but the most i can put in with the combo of chips i have is 384
[01:47:04] <chr0n1c> i have a ton of 64 mb's
[01:47:10] <chr0n1c> sdrams*
[01:47:33] <skullworks-GAB2> BIOS limit
[01:48:34] <skullworks-GAB2> have a ASUS P2B-S that will take 1 gb - 4x 256
[01:49:00] <skullworks-GAB2> same chipset - but better BIOS (beta)
[01:49:35] <cradek> there were bios updates for some of those old boards that allowed higher clock speeds
[01:49:53] <skullworks-GAB2> not these GTW
[01:50:27] <chr0n1c> can emc take advantage of clusters of old boxes...
[01:50:39] <skullworks-GAB2> BIOS was done by intel and Phnx
[01:50:40] <chr0n1c> and use the multiple paralell posrts in them?
[01:50:52] <chr0n1c> beowolf... etc...
[01:51:05] <skullworks-GAB2> cable entangle
[01:51:09] <chr0n1c> ports*
[01:51:30] <skullworks-GAB2> 1 wire comes loose = hours of trouble shooting
[01:51:37] <chr0n1c> yeah...
[01:51:50] <chr0n1c> but in theory it would work?
[01:51:56] <chr0n1c> for cpu juice and inputs?
[01:52:21] <skullworks-GAB2> best idea was running the gui on one - motion on another
[01:52:36] <chr0n1c> that sounds interesting
[01:52:45] <skullworks-GAB2> thats as far as I want to distribute
[01:52:55] <chr0n1c> i mean... i would try possibly if only for the free inputs
[01:53:18] <chr0n1c> it doesn't get cheaper than a cat5 cable and a trash computer
[01:53:28] <skullworks-GAB2> sounds like a setup nightmare
[01:53:46] <skullworks-GAB2> same port address diff box address
[01:54:10] <chr0n1c> sent over lan to a diff address on the motion box...
[01:54:15] <chr0n1c> mapped*
[01:54:26] <chr0n1c> or serial link...
[01:54:31] <chr0n1c> i dunno how that works though
[01:54:40] <chr0n1c> i like lots of cables everywhere
[01:54:43] <chr0n1c> lol
[01:54:49] <skullworks-GAB2> also boxes might not be able to run the same period or maintain sync
[01:54:57] <chr0n1c> good point
[01:55:07] <chr0n1c> and latency between boxes
[01:55:28] <skullworks-GAB2> but - Mazak does the dual PC
[01:55:46] <chr0n1c> hmm
[01:55:49] <skullworks-GAB2> one for motion - one for operator panel
[01:56:18] <chr0n1c> a full pc.. or just a cpu board...
[01:56:31] <skullworks-GAB2> gets strange when one reboots without the other knowing...
[01:56:59] <chr0n1c> i really wanted to rip open the milltronics and put a cdrom and windows and network.. they wouldn't let me
[01:57:05] <skullworks-GAB2> have not seen these new Mazaks
[01:57:17] <chr0n1c> i had to keep opening the pc box up and tweaking the vga cable
[01:57:22] <chr0n1c> so i found the heart!
[01:57:31] <chr0n1c> a 586 pc
[01:57:35] <chr0n1c> with 128 mb ram
[01:57:41] <chr0n1c> open slots.. pci and isa
[01:58:02] <chr0n1c> only 1 pci slot was used for the motion interface card
[01:58:28] <skullworks-GAB2> well - I have to go exhibit childish behavor
[01:58:38] <chr0n1c> hell yeah
[01:59:21] <skullworks-GAB2> its the EX GTW crowd getting togather at VS Gaming centers for some networked carnage
[01:59:41] <skullworks-GAB2> last time was BF2
[01:59:50] <skullworks-GAB2> Tonite will be FEAR
[02:00:30] <skullworks-GAB2> nice to play on super geek hardware
[02:00:51] <skullworks-GAB2> Nvida 7800GT 512mb
[02:00:59] <skullworks-GAB2> OOOH
[02:02:11] <skullworks-GAB2> anyway - I'm out for now
[02:09:17] <Jymmm> Ok, usdigital has $20 encoders, what would I need to utilize them?
[02:09:31] <jmkasunich> encoders are not the answer to your problems
[02:10:05] <Jymmm> jmkasunich: Just a way to provide feedback with long term (hours?) testing
[02:10:34] <jmkasunich> you mean so it would trip on a sort of "following error" as soon as something goes wrong?
[02:10:35] <Jymmm> I figure I'd log the errors and try to see if there's a pattern
[02:11:28] <Jymmm> jmkasunich: Well, I'd hope to be able to use something like halscope (with data logging) and then when the commend position is not actual position logg all of it.
[02:11:57] <Jymmm> soo if it's only when all axis are in motion, some are in motion, in a curve, rapid, etc
[02:11:59] <jmkasunich> for that you need two free parport input pins per channel that you want to monitor
[02:12:12] <jmkasunich> plus encoders with the right ppr
[02:12:30] <jmkasunich> ideally, the encoder COUNTS (not lines) per rev would be the same as the motors steps per rev
[02:12:31] <Jymmm> Ok, I have a dual paraport PCI card, I've neer used yet.
[02:12:45] <jmkasunich> you are doing 200 step/rev x 8 microsteps, so 1600
[02:12:54] <jmkasunich> you want 400 line / 1600 count encoders
[02:12:58] <Jymmm> 1600 or you mean 16000
[02:13:05] <jmkasunich> 1600
[02:13:13] <jmkasunich> you're gonna put them on the steppers right?
[02:13:33] <Jymmm> right, sorry I was thinking with the 10TPI leadscrews, nm
[02:13:39] <jmkasunich> np
[02:14:05] <jmkasunich> then you just have some hal-fu
[02:14:26] <jmkasunich> parport -> encoder (hal component) -> sum ->
[02:14:39] <jmkasunich> the other input of sum is the position feedback from stepgen
[02:14:50] <Jymmm> Yeah, something like that is what I was thinking. I just need some way to get moe data to narrow done the caue, everything so far is jsut guessing.
[02:14:51] <jmkasunich> where stepgen thinks it is, minus where the encoder says it is
[02:15:13] <jmkasunich> then feed the sum output to a window comparator with a narrow window, it will go true when they don't match
[02:16:17] <Jymmm> jmkasunich Can emc do datalogging, ?
[02:16:45] <jmkasunich> hal can
[02:16:49] <jmkasunich> something called sampler
[02:16:58] <cradek> Jymmm: please say you're not using that laptop with known realtime problems still
[02:17:11] <Jymmm> and hal can "tap" into the encoder signals?
[02:17:22] <Jymmm> cradek that was three different machiens ago.
[02:17:27] <cradek> ok
[02:17:44] <cradek> so no realtime problems now? latency test looks good?
[02:17:48] <Jymmm> Dual P3 1Ghz with 2GB ram and ovl max of 15115
[02:17:55] <cradek> great
[02:18:03] <cradek> ok I'll butt out again :-)
[02:18:16] <Jymmm> Thought the onboard video only has 4BM, so I got max of 1024x768 I cna live with it
[02:18:41] <Jymmm> cradek (as long as I dont run glxgears =)
[02:18:45] <jmkasunich> Jymmm: yes, hal can tap into them... hal is the only place they exist
[02:18:51] <cradek> 4MB gets you 1600x1200x16bit
[02:19:05] <Jymmm> cradek good to know.
[02:19:35] <cradek> simple matter of multiplication...
[02:20:13] <Jymmm> jmkasunich What I was thinking is coming up with some "known" patterns (gcode), run them and log commanded position and actual position, then analize all three items.
[02:20:39] <Jymmm> probably among other things.
[02:20:52] <jmkasunich> you should be able to run any program
[02:20:57] <jmkasunich> but the sampler output will be hute
[02:20:59] <jmkasunich> huge
[02:21:07] <jmkasunich> one line of numbers every 0.001 seconds
[02:21:10] <Jymmm> more than 2gb?
[02:21:36] <jmkasunich> no
[02:21:52] <jmkasunich> about 100-200 meg per hour, depending on how many variables you choose to capture
[02:22:21] <chr0n1c> variables are the spice of life!
[02:22:40] <chr0n1c> ok... sorry
[02:22:44] <chr0n1c> that was cheesy
[02:22:49] <cradek> ha
[02:23:22] <chr0n1c> i jsut found a cnc lathe lens mold production program chris...
[02:23:37] <chr0n1c> it estimates focal lentgh and such
[02:23:41] <cradek> cool
[02:23:42] <chr0n1c> but it's for windows
[02:23:56] <Jymmm> Sorry for the lag, at work, eeeesh customer want me to help them. how rude!!!!
[02:24:16] <chr0n1c> "i don't know anything about that... i jsut work here..."
[02:24:37] <chr0n1c> just* (damn)
[02:24:48] <Jymmm> jmkasunich I can tosse the raw data into a db and analyze it
[02:25:04] <jmkasunich> ok
[02:25:11] <Jymmm> chr0n1c Yeah, I've been using that for a long time, I think they caught on now
[02:25:13] <jmkasunich> sampler just prints lines to stdout
[02:25:23] <chr0n1c> jsut make parts and toss out the bad ones.. you're missing the fun!
[02:25:25] <jmkasunich> you can redirect into a file, then process any way you like
[02:26:04] <Jymmm> jmkasunich I think I'll just need a refernce point, a timestamp of sorts would help
[02:26:30] <chr0n1c> you could add g-code line numbers also...
[02:26:45] <chr0n1c> to cross reference with the program
[02:26:45] <cradek> are you talking about logging encoder position so you can see what it's doing when it goes wrong?
[02:26:48] <jmkasunich> that would be much harder, gcode numbers don't exist in hal
[02:26:56] <chr0n1c> oh
[02:27:03] <Jymmm> cradek among other things.
[02:27:08] <cradek> jmkasunich: I think they might...?
[02:27:16] <jmkasunich> maybe
[02:27:24] <cradek> at least they did at one moment in history
[02:27:38] <jmkasunich> you probaby know better than I
[02:27:49] <jmkasunich> if you took some tp internals and exported them to hal for scopeing
[02:28:02] <jmkasunich> unfortuately sampler can only sample pins, not params...
[02:28:11] <cradek> I thought that was one we decided to keep, but maybe not
[02:28:19] <jmkasunich> yet another case where it might be nicer to have everything be a pin
[02:28:29] <Jymmm> jmkasunich Ok, so encoders can connect directly to paraport or is there some other components I'd need?
[02:28:45] <jmkasunich> you mean on the outside (the hardware world)?
[02:29:00] <cradek> emcmot_hal_data->debug_s32_0 = emcmotStatus->id;
[02:29:06] <jmkasunich> or in the hal world?
[02:29:20] <Jymmm> well, someone suggested the E4P fro usdigital iirc let me grba the url. I'm not sure if even those are what I need.
[02:29:35] <jmkasunich> you need something with 400 lines/1600 counts per rev
[02:29:56] <Jymmm> http://www.usdigital.com/products/e4p/
[02:30:02] <jmkasunich> if its outputs are TTL, you just need power for it (probably 5V, steal from the PC) and connect the signals to the parport
[02:30:14] <Jymmm> 5v/12v no problem
[02:30:23] <Jymmm> I have a 30 variable PS too
[02:30:31] <Jymmm> I have a 30a variable PS too
[02:30:50] <cradek> stopping when it goes wrong would be much easier than using sampler
[02:31:11] <jmkasunich> 100 to 300 cycles per rev, 400 to 1200 pulses per rev - not quite what you want
[02:31:30] <jmkasunich> but close, you could detect 2 or 3 missed steps reliably, but not 1
[02:31:54] <jmkasunich> (1 would be tough in any case, there will always be at least a +/- 1 ambiguity)
[02:31:57] <Jymmm> cradek: The BIGGEST issue i have is I can't repeat the problem, if I can't repeat it, I dont know what to fix. the idead of the encoders is to give feedback to try and determine when/where the problem might be
[02:32:21] <Jymmm> jmkasunich Tht was just someones suggestion, that's all.
[02:32:21] <jmkasunich> Jymmm: I still think you haven't really tried to repeat it
[02:32:22] <chr0n1c> who can do pcb/component design?
[02:32:47] <jmkasunich> chr0n1c: lots of us can
[02:32:51] <jmkasunich> only a few want to
[02:33:06] <cradek> heh
[02:33:07] <Jymmm> jmkasunich If I run my machine "over the limits" I can get it to stall all the time, but it's never in the same place.
[02:33:29] <cradek> yep steppers are like that
[02:33:32] <jmkasunich> does it matter if its not always in the same place?
[02:33:45] <jmkasunich> the fact that it stalls tells you you are over the limit
[02:33:49] <Jymmm> jmkasunich If $60 worth of encoders help me to determine what/where the issue is once and for all, I can live with that.
[02:33:50] <cradek> run at 70% that speed and you'll be fine
[02:33:58] <jmkasunich> if it stalls once in a great while, it says you are very close to the limit
[02:34:06] <chr0n1c> ok, how can i distribute a 555 timer output to terminal blocks.. with a switch for 8/6/4 wire motors...
[02:34:16] <chr0n1c> something with a forward and revers button....
[02:34:34] <jmkasunich> Jymmm: its quite possible that $0 worth of thinking can get you where you need to be
[02:34:43] <chr0n1c> as simple as can be only to help figure out the coils and such
[02:34:57] <cradek> chr0n1c: 4 buttons is simpler
[02:34:58] <Jymmm> jmkasunich There have been times I've run multiple 20 minute jobs, not problem. Thern run a 120 job and it stalls at 90 minutes itnot it.
[02:35:06] <Jymmm> 120 minute
[02:35:05] <jmkasunich> whats harder, decoupling the motors and running some tests that way, or mounting and wiring the encoders?
[02:35:14] <chr0n1c> 4 push button all on v+
[02:35:23] <chr0n1c> to some terminals...
[02:35:30] <cradek> chr0n1c: yes but that isn't enough for 4 wire motors of course
[02:35:35] <chr0n1c> with a 9 volt batt or something...
[02:35:37] <jmkasunich> chr0n1c: what are you trying to do with the motors?
[02:35:41] <cradek> chr0n1c: just use an ohmmeter
[02:35:50] <jmkasunich> spin them? or just work out the wiring diagram?
[02:35:59] <chr0n1c> i jsut want to figure out wiring diagrams for random steppers
[02:36:03] <chr0n1c> like with no label
[02:36:19] <jmkasunich> that takes an ohmeter, a battery, pencil, paper, and logic
[02:36:21] <jmkasunich> not a circuit
[02:36:22] <Jymmm> chr0n1c short two wires together, if you can't turn the shaft, you found the pair.
[02:36:23] <chr0n1c> but something that can take the 555 and spin the signal to all the posts in order enough for an 8 wire
[02:36:50] <chr0n1c> not even a control really...
[02:36:53] <chr0n1c> jsut a test card
[02:36:59] <jmkasunich> you don't need that
[02:37:04] <Jymmm> chr0n1c Seriously... short two wires together, if you can't turn the shaft, you found the pair.
[02:37:10] <jmkasunich> right
[02:37:11] <cradek> you'll just burn it up
[02:37:14] <cradek> Jymmm is right
[02:37:26] <chr0n1c> i was thinking it would be a fun pcb to mill for my first diy pcb...
[02:37:27] <cradek> and we don't say that very often
[02:37:29] <cradek> :-)
[02:37:58] <chr0n1c> if i had some direction to go for a chip to spin the output... i might be able to come up with something with the help of eagle
[02:38:16] <chr0n1c> m'kay...
[02:38:31] <Jymmm> chr0n1c try it with any stepper motor you have alying aorund.
[02:38:33] <jmkasunich> say you have an 8 wire motor.....
[02:38:39] <jmkasunich> label one wire "1"
[02:38:59] <jmkasunich> then one at a time, hook another wire to it (just one) and try to spin the shaft
[02:39:06] <jmkasunich> for 7 of them, it will spin easily
[02:39:13] <jmkasunich> for 6 I mean
[02:39:29] <chr0n1c> * chr0n1c runs to the shelf
[02:39:30] <jmkasunich> for the 7th it will turn hard and coggy, or not at all depending on how strong the motor is
[02:39:33] <jmkasunich> label that one 2
[02:40:06] <jmkasunich> then disconnect those two and pick another at random from the remaining 6, label it "3"
[02:40:23] <jmkasunich> connect one at a time from the 5 remaining unlabeled wires to 3
[02:40:30] <jmkasunich> the one that makes it hard to turn is 4
[02:40:36] <jmkasunich> repeat for 5, 6 and 7,8
[02:40:48] <jmkasunich> that gives you the four windings, but not the relative phasing
[02:41:07] <jmkasunich> next step:
[02:41:14] <jmkasunich> twist together 1 and 2
[02:41:20] <jmkasunich> the shaft will be coggy
[02:41:36] <jmkasunich> if you can't turn it at all, use a wrench or something for leverage
[02:41:49] <jmkasunich> then leave 1 and 2 connected, and hook 3 to 4
[02:42:03] <chr0n1c> ok black and black/white are tough(er) to turn
[02:42:05] <jmkasunich> if its still coggy, 34 and 12 are one pair of windings
[02:42:16] <jmkasunich> how many wires is this stepper?
[02:42:31] <chr0n1c> 8
[02:42:43] <jmkasunich> ok
[02:42:44] <cradek> then the pairs are color and color/white
[02:42:56] <jmkasunich> got tape and a pencil/marker? mark those two
[02:43:05] <chr0n1c> it's japan servo...
[02:43:10] <chr0n1c> it should have specs on the net
[02:43:16] <chr0n1c> but i couldn;t find one similar
[02:43:22] <chr0n1c> or this onein particular
[02:43:32] <jmkasunich> cradek: don't cheat - lets assume there is no coloring or anything at all
[02:43:33] <Jymmm> chr0n1c so you know the brand name but not the model# ?
[02:43:42] <chr0n1c> have that also
[02:43:52] <Jymmm> chr0n1c what is it?
[02:43:56] <cradek> jmkasunich: sorry (but there always is!)
[02:43:58] <jmkasunich> we digress - I'm willing to walk you thru the process of finding out the pinout with NO external information at all
[02:43:59] <chr0n1c> kp6m2-013
[02:44:18] <cradek> I'm interested in hearing the phasing trick
[02:44:25] <chr0n1c> i am following you on the pinout thing , ty
[02:44:37] <jmkasunich> ok, you got 1 and 2 labeled?
[02:44:44] <jmkasunich> I should put this on a wiki page instead....
[02:44:54] <cradek> yeah that would be great
[02:45:03] <Jymmm> jmkasunich (copy and paste from the lags later)
[02:45:13] <Jymmm> logs
[02:45:35] <jmkasunich> chr0n1c: has 6 more wires to find and label, I already explained that part
[02:45:39] <jmkasunich> I'll start the wiki page
[02:45:51] <jmkasunich> copy/paste will need lots of editing, I'd rather write from scratch
[02:45:58] <chr0n1c> jsut opened up notepad.. going to start
[02:46:33] <Jymmm> jmkasunich dont' forget the lil trick to connect two steppers together and you spin one shaft which make sthe one shaft spin too =)
[02:47:37] <chr0n1c> ok.. yellow/yellow-white 3/4...
[02:47:55] <skunkworks> dad has a bunch of sealed cans of syncos (military) - those are fun to hook up :)
[02:48:15] <skunkworks> syncros
[02:49:19] <chr0n1c> 4/5 r/r+w
[02:49:33] <jtr> skunkworks: glad you had the 'n' in the first one - I would have worried. ;-)
[02:50:01] <skunkworks> :)
[02:50:09] <chr0n1c> ehh so i got my numbering off
[02:50:09] <chr0n1c> lol
[02:52:34] <chr0n1c> ok 1/2 + 3/4 together make it still cog but at smaller increments...
[02:52:39] <chr0n1c> sound right?
[02:52:59] <jmkasunich> try 1/2+3/4, then 1/2+5/6, then 1/2+7/8
[02:53:22] <jmkasunich> two of the three should make it hard to turn but much finer cogging, or even no cogging
[02:53:39] <jmkasunich> the third combo will make the cogging the same or worse than 1/2 alone
[02:54:00] <chr0n1c> ok 3 out of three still fine(er) cog
[02:54:07] <jmkasunich> ?
[02:54:38] <chr0n1c> 1/2.. 3/4/... 5/6... together in bundles
[02:54:54] <jmkasunich> nope
[02:55:00] <chr0n1c> i have all 8 wires in pairs of two connected
[02:55:05] <jmkasunich> you don't want three pairs connected at once (or four)
[02:55:08] <jmkasunich> only two pairs
[02:55:10] <chr0n1c> am i followin you right?
[02:55:13] <jmkasunich> 1/2+3/4
[02:55:20] <jmkasunich> then disconnect 3/4
[02:55:23] <jmkasunich> 1/2+5/6
[02:55:28] <jmkasunich> then disconnect 5/6
[02:55:30] <jmkasunich> 1/2+7/8
[02:56:31] <chr0n1c> ok 1/2 + 7/8 in bundles.. makes rough cogging
[02:56:55] <jmkasunich> ok, that means 1/2 and 7/8 are two windings that go together
[02:56:57] <chr0n1c> and i think i am getting small doses of current in my fingers
[02:56:58] <chr0n1c> :|
[02:57:15] <jmkasunich> yeah, when you turn the motor it acts like a generator
[02:57:30] <Jymmm> did we forget to tell you that part?
[02:57:39] <jmkasunich> since 7/8 go with 1/2, relabel them
[02:57:56] <jmkasunich> make 7/7 -> 3/4 and make 3/4 -> 7/8
[02:57:57] <chr0n1c> that is a nice trick
[02:58:14] <jmkasunich> oops, 7/8, not 7/7
[02:58:42] <jmkasunich> tell me when you got them relabeled
[02:59:11] <jtr> question - 1/2 doesn't have to be connected to 3/4, right? 1 connects to 2, and 3 connects to 4 is sufficient?
[02:59:18] <jmkasunich> yes
[03:01:04] <jtr> Ok. when chr0n1c said "in bundles", I wondered if he was wasting effort
[03:01:05] <chr0n1c> ok.. so 5/6 + 7/8 are bundled
[03:01:23] <chr0n1c> relabeled
[03:01:37] <jmkasunich> ok, now we need to figure out polarity
[03:01:41] <jmkasunich> hook 1 to 3
[03:01:52] <jmkasunich> (twisted them together, etc)
[03:02:01] <jmkasunich> everything else disconnected
[03:02:12] <chr0n1c> ok..
[03:02:14] <jmkasunich> you should be able to spin it with no (very little) resistance
[03:02:34] <jmkasunich> then hook 2 to 4 (only, don't lump them in with 1 and 3)
[03:02:40] <jmkasunich> and try to spin it
[03:03:10] <jmkasunich> easy or hard?
[03:03:20] <chr0n1c> easy...
[03:03:30] <jmkasunich> ok, that means the two windings are in parallel
[03:03:33] <chr0n1c> easy w/o 2+4
[03:03:43] <jmkasunich> what about with 2+4?
[03:03:45] <chr0n1c> hard with
[03:04:02] <jmkasunich> then the two windings are in series
[03:04:20] <jmkasunich> switch the labels on 3 and 4
[03:04:35] <jmkasunich> lemme know when that is done
[03:04:56] <chr0n1c> yup
[03:04:59] <chr0n1c> check
[03:05:10] <jmkasunich> ok, disconnect everything again
[03:05:22] <jmkasunich> then twist together 5 and 7
[03:05:31] <jmkasunich> should spin easy
[03:05:46] <chr0n1c> cog
[03:05:52] <chr0n1c> coggy
[03:05:57] <jmkasunich> only 5 and 7 are connected?
[03:06:08] <chr0n1c> oh
[03:06:12] <chr0n1c> read that wrong
[03:06:28] <chr0n1c> y brain saw 5 and told itself 6 is next ;)
[03:06:47] <chr0n1c> ok free spin
[03:06:58] <jmkasunich> ok, leave 5 & 7 connected
[03:07:11] <jmkasunich> hook 6 to 8 (but not to anything else)
[03:07:17] <jmkasunich> hard or easy spin?
[03:07:30] <chr0n1c> hard
[03:07:44] <jmkasunich> ok, they're in series again
[03:07:48] <jmkasunich> swap 7 and 8
[03:07:53] <jmkasunich> (labels)
[03:08:16] <jmkasunich> congradulations, you have identified all the leads on that motor
[03:08:18] <chr0n1c> check
[03:08:21] <chr0n1c> thanks..
[03:08:27] <chr0n1c> now lets find the schematic
[03:08:28] <chr0n1c> lol
[03:08:41] <chr0n1c> i appreciate you leading me through that
[03:08:46] <chr0n1c> it shodl stick inmy head now
[03:09:42] <chr0n1c> should*
[03:09:42] <chr0n1c> but it will be in the wiki you say?
[03:09:42] <chr0n1c> that would be good info for lots of ppl
[03:09:42] <jmkasunich> for series, hook 1 to the drive "A+", 2 to 3, and 4 to the drive "A-", 5 to drive "B+", 6 to 7, and 8 to drive "B-"
[03:09:45] <jmkasunich> for parallel, hook 1 and 3 to drive "A+", 2 and 4 to drive "A-", 5 and 7 to drive "B+", and 6 and 8 to drive "B-"
[03:09:56] <jmkasunich> yeah, I'll wiki it
[03:10:29] <chr0n1c> i'm not sure which is better?
[03:10:44] <chr0n1c> i want to make it a 6 wire to replace one of my motors now
[03:10:54] <chr0n1c> it seems like it has more tourque
[03:11:06] <chr0n1c> maybe my x now that i think about it
[03:11:12] <jmkasunich> is it a unipolar drive (6 wire)?
[03:11:13] <chr0n1c> since it has the most weight
[03:11:23] <chr0n1c> yes my drive
[03:11:33] <jmkasunich> ok, I gave the connections for bipolar
[03:11:44] <chr0n1c> aka 4 wire?
[03:11:49] <jmkasunich> for unipolar there is only one choice
[03:11:49] <jmkasunich> yes
[03:12:52] <chr0n1c> 1/3 common... 2/4 a/A?
[03:13:05] <chr0n1c> a guess*
[03:13:13] <jmkasunich> for uni: 1 to drive "A1", 2 & 3 together is center tap for A, 4 to drive "A2" , 5 to drive "B1", 6 & 7 together is center tap for B, and 8 is "B2"
[03:16:31] <chr0n1c> so 2/3 + 6/7.. should = no resistance
[03:16:39] <chr0n1c> *turning
[03:16:49] <jmkasunich> right
[03:16:56] <chr0n1c> sweet
[03:16:59] <chr0n1c> we are in there then
[03:17:04] <chr0n1c> ty..
[03:17:04] <jmkasunich> you should be able to short all four of those together and have no resistance
[03:17:09] <jmkasunich> you're welcome
[03:17:38] <chr0n1c> i think i paid $3.50 at the most for this stepper
[03:17:51] <chr0n1c> it was marked $4.50
[03:18:16] <chr0n1c> ther ewas a bunch of 8 wire.. i didn't see any 6 wire.. except for the pancake type
[03:18:36] <jmkasunich> 8s are better anyway
[03:18:45] <jmkasunich> you can make an 8 into a 6, but not the other way around
[03:18:48] <chr0n1c> there was some tiny tiny steppers.. for a register tape motor or something maybe
[03:19:11] <chr0n1c> i heard mendelsons is moving...
[03:19:19] <chr0n1c> someone told me the city of dayton bought the building
[03:19:32] <chr0n1c> it's right next to our AAA baseball
[03:19:38] <chr0n1c> stadium*
[03:20:16] <chr0n1c> or.. going out of biddness
[03:20:19] <chr0n1c> :o
[03:42:12] <Jymmm> silly question, but do you think the optiocs in a mouse would be good enough to gut?
[03:43:32] <chr0n1c> the encoders in the old mice don't have good resolutions
[03:43:53] <Jymmm> Not the wheels, just the optics and maybe the PIC
[03:44:06] <Jymmm> The IR stuff
[03:44:11] <chr0n1c> ah
[03:45:57] <Jymmm> bbiab, foodage
[03:49:28] <jmkasunich> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?StepMotorWireIdentification
[03:49:38] <jmkasunich> can somebody read that and tell me if its clear?
[04:01:39] <chr0n1c> i scanned through it.. loks nice
[04:01:42] <chr0n1c> looks*
[04:02:12] <chr0n1c> i didn't even see any typos jump out
[04:04:37] <chr0n1c> maybe mention something about possible shock at the top lol
[04:04:50] <chr0n1c> i got a tiny bit of juice in my hand
[04:07:57] <chr0n1c> 2x2" iron cross inlaid into a pc. of smoked lexan... 100 mins
[04:08:06] <chr0n1c> with 3d skulls inside*
[04:08:28] <chr0n1c> milled x then y
[04:08:39] <chr0n1c> x/z then y//z
[04:09:00] <chr0n1c> .040 ballnose endmill....
[04:09:24] <chr0n1c> axis only chokes on the code when it has to draw the cutter path on top of the g-code path
[04:09:37] <chr0n1c> as it's milling i just refresh to clear some cutterpath
[04:09:50] <chr0n1c> so the pc won't bog down
[04:11:35] <chr0n1c> can emc takeover the ##cnc channel i started to register last night?
[04:11:36] <skunkworks> chr0n1c: jepler made it so you can turn off the live plot but still have the cone. it is only in head though.
[04:11:53] <chr0n1c> i haven't got balls to try any cvs stuff yet
[04:12:09] <chr0n1c> i enjoy running the machine too much to tear down the code and try new ;)
[04:12:16] <skunkworks> :)
[04:15:25] <chr0n1c> head=cvs in coder talk right? lol
[04:16:01] <skunkworks> yes - although it isn't that bad - you can run trunk (used to be called head) without screwing up the installed emc.
[04:16:04] <chr0n1c> i think i broke thier code cap'n!
[04:17:10] <chr0n1c> do coders use apaches indians to spread radio chatter? so the lames don't know what they are saying?
[04:17:32] <chr0n1c> lol... i just watched a documentary on wwII
[04:17:44] <skunkworks> Jymmm:
http://www.electronicsam.com/images/KandT/servostart/Fastermouse.png
[04:17:59] <chr0n1c> they should show more things about cnc/machines on discovery
[04:18:55] <chr0n1c> right.. you wouldn't tell me if you did use them.. ;)
[04:20:11] <Jymmm> skunkworks: Heh, is that good or bad???
[04:20:51] <Jymmm> skunkworks: did you jsut use a serial mouse?
[04:27:21] <skunkworks> Jymmm: I hooked directly into the Ir reciever.
[04:28:12] <Jymmm> each channel being X and Y ?
[04:28:40] <skunkworks> no - that is only one reciever. Quadature output.
[04:29:42] <Jymmm> Ok, I guess i need to read up on "quadature encoding" some mroe
[04:30:35] <skunkworks> http://members.shaw.ca/swstuff/mouse.html
[04:30:46] <skunkworks> that is LawrenceG's site.
[04:31:44] <Jymmm> ah, ok. I wonder if I draw up an encoder ring with much higher "slits" and get it rinted on mylar film if that would work.
[04:31:53] <skunkworks> the mice that I had was around 60 lines. to get say 400 I would have had to cut a disk around 4 inches in diameter to get the correct spacing (so it was in proportion to the original disk)
[04:32:07] <skunkworks> iirc
[04:32:12] <jmkasunich> Jymmm: you can't change the spacing between the lines
[04:32:15] <skunkworks> it has been a month or so.
[04:32:20] <jmkasunich> so for more lines you need a bigger diameter
[04:32:44] <Jymmm> Well, mouse wheel is about 3/4", I was thinking maybe 1.5 to 2"
[04:33:00] <jmkasunich> that will get you 2 to 3 times the counts per rev
[04:33:02] <skunkworks> draw it up in cad and you will see..
[04:33:28] <jmkasunich> a mouse is something like 64 counts/rev I think, so you will get a couple hundred tops
[04:34:01] <Jymmm> jmkasunich: but the optics/electronics should be able to handle it?
[04:34:06] <Jymmm> if I replace the wheel
[04:34:15] <jmkasunich> the optics don't know the difference
[04:34:22] <jmkasunich> they only care about the count rate
[04:34:28] <jmkasunich> you could even make a linear encoder
[04:34:30] <Jymmm> Ok, I dind't know if they were fast enough.
[04:34:48] <jmkasunich> you can't increase the speed beyond what they do in a mouse
[04:35:13] <jmkasunich> if the mouse shaft can handle 10 revs per second, and you make the disk twice as big, the new top speed will be 5 revs per second
[04:35:15] <Jymmm> jmkasunich: Well, i thought they might use cheap IR Rx
[04:35:20] <jmkasunich> (same number of counts per second)
[04:35:33] <ds3> isn't a high res optical mice + a cylinder for the mouse to 'see' easier to do?
[04:35:47] <jmkasunich> ds3: no
[04:35:57] <ds3> why?
[04:35:58] <jmkasunich> high res mice don't have quadrature output
[04:36:01] <Jymmm> ds3: Optical mice use a tiny CCD camera
[04:36:10] <jmkasunich> they convert directly from camera into serial messages to the PC
[04:36:16] <ds3> right... but why not just use what hte mice report to the PC?
[04:36:22] <skunkworks> I was getting 20K counts out of it - if you look at the halscope
[04:36:34] <Jymmm> skunkworks: per rev?
[04:36:38] <jmkasunich> ds3: 1) not realtime 2) not precise
[04:36:38] <ds3> oh you want to keep the rest of the software the same
[04:36:49] <ds3> jmkasunich: gotcha
[04:37:03] <jmkasunich> nobody cares if a mouse reports 3.000 inches but you actually moved it 3.027
[04:37:51] <skunkworks> jymmm: per second.
[04:38:10] <Jymmm> skunkworks: oh.
[04:38:23] <skunkworks> didn't seem to have an issue with that but it was about the limit of the base period I had iirc
[04:39:53] <skunkworks> night
[04:39:59] <Jymmm> G'Night
[04:41:18] <Jymmm> jmkasunich: you said I couldn't chang ethe spacing, why not?
[04:41:42] <jmkasunich> because the spacing of the two detectors in the optical assembly has to match the slots in the wheel
[04:42:28] <Jymmm> oh, or they'll "overlap" ?
[04:42:35] <jmkasunich> yes
[04:42:58] <Jymmm> Ok, so I have to give it more slots, meaing larger wheel.
[04:43:05] <jmkasunich> right
[04:43:10] <ds3> which way is it on a mouse - the wheel has quad. slots or the LEDs/receiver are arrange to generate quad from plain slots?
[04:43:21] <jmkasunich> single row of slots in the wheel
[04:43:36] <jmkasunich> two detectors, offset by 1.5, 2.5, or some such slot spacings
[04:43:48] <jmkasunich> the half-slot offset gives quadrature
[04:44:04] <jmkasunich> whole slot offset is just to provide physical spacing as needed for packaging
[04:44:55] <jmkasunich> some older mice actually had the A and B detectors on opposide sides of the disk, 180 degrees +/- one half slot apart
[04:45:23] <ds3> Hmmmmmm interesting
[04:45:52] <ds3> what about using the photo diodes quad on a CDROM head as a the detector to generate quad signals? think they may be smaller
[04:46:13] <jmkasunich> no idea
[04:46:19] <ds3> (quad as a 2x2 array)
[04:46:53] <jmkasunich> microsurgery to remove it, and photodiodes need amplification
[04:47:33] <jmkasunich> could be done, but time, energy, and additional parts start making regular encoders competitive
[04:47:38] <ds3> removal isn't too much of a problem....
[04:47:57] <ds3> it is just a 4 inch wheel is pretty big
[04:48:06] <jmkasunich> no sh_t
[04:48:25] <jmkasunich> thats why high resolution encoders don't use mouse guts
[04:48:36] <ds3> guess, all this effort is bounded by the price of the USdigital encoders
[04:48:45] <jmkasunich> good fast cheap, pick 2
[04:48:53] <jmkasunich> mouse guts: fast and cheap
[04:49:15] <jmkasunich> cdrom: good and maybe cheap, not fast because you got a lot more reverse engineering to do
[04:49:23] <jmkasunich> us digital: good and fast, not cheap
[04:49:27] <ds3> IMO, mouse guts just won't cut it but I am looking at making a simple measuring/DRO type thing
[04:49:34] <jmkasunich> actually they are pretty darned cheap by industrial standards
[04:50:01] <Jymmm> just pulling this out of my ass.... what abut a hall effect?
[04:50:18] <ds3> games with magnetic toner?
[04:50:23] <jmkasunich> for a linear scale, the critical part isn't so much the sensor, its what the sensor looks at
[04:50:27] <Jymmm> oh nm, that's RPM's
[04:50:42] <Jymmm> http://www.usdigital.com/products/e4p/pictures/miniature-optical-kit-encoder-e4p.jpg
[04:50:50] <Jymmm> I wish that was a hi res image
[04:51:10] <ds3> any idea what speed you can read a capactive encoder at?
[04:52:32] <Jymmm> Damn, how are they getting 2500 out of that thing?!
http://www.usdigital.com/products/e6/pictures/optical-kit-encoder-e6s.jpg
[04:52:47] <jmkasunich> very fine lines
[04:56:51] <Jymmm> Man $65/ea
[05:00:18] <jmkasunich> very fine lines ;-)
[05:00:27] <Jymmm> lol
[05:00:49] <Jymmm> yeah, I just need some way to get feedback is all.
[05:01:59] <ds3> feed back on your steppers?
[05:02:01] <ds3> or ?
[05:04:47] <ds3> is there a quick start guide to adding a page to the wiki? if so, anyone got the URL handy?
[05:07:39] <Jymmm> ds3: Well, I need some wat to get feedback from my machine, then I can start making cmparisions with other colelcted data.
[05:08:17] <Jymmm> I could get away with two encoders, but not one in th elong run.
[05:09:05] <Jymmm> and if the problem I'm having happens to be the xylotex and lack of mid band filtering, well 3 encoders is 1 gecko that does have that circuitry
[05:11:13] <chr0n1c> i want to buy some colors for my website...
[05:11:18] <chr0n1c> i need to buy black grey and blue
[05:12:20] <Jymmm> * Jymmm sells chr0n1c #FFFFFF, #888888, #0000FF for $29.95 + shipping
[05:12:51] <jmkasunich> black is #000000 isn't it?
[05:13:20] <Jymmm> jmkasunich: (shhhhhhh, I' have an excess of "#FFFFFF"
[05:13:42] <jmkasunich> sorry
[05:13:49] <Jymmm> (tis okey =)
[05:14:25] <chr0n1c> ;) thanks
[05:14:48] <chr0n1c> * chr0n1c forks over boatloads of cash
[05:15:06] <Jymmm> doesn't that Rx/Tx pair look like it's on the same side?
http://www.usdigital.com/products/e4p/pictures/miniature-optical-kit-encoder-e4p.jpg
[05:15:20] <Jymmm> so tha tthe disc would have to reflect it back?
[05:15:46] <ds3> Jymmm: one cheap alternative is to rummage through Triangle... I got a pair of NEMA23 (~200oz-in) w/US digital encoders on them for $14 total
[05:15:49] <Jymmm> i wonder if there's a reflector inside the cover
[05:16:09] <Jymmm> ds3: Where in the store? front?
[05:16:24] <ds3> yeah, I found them on the left side of the entrance
[05:16:36] <Jymmm> LEFT side?
[05:16:47] <ds3> yeah, as you enter... the glass cases is on the right side
[05:16:59] <ds3> there is a pile of small motors, steppers, etc on the left side
[05:17:10] <Jymmm> near the roll up door?
[05:17:11] <chr0n1c> pass the motor to the left hand side... oh lalala.. pas the motor to the left hand side...
[05:17:16] <ds3> yep
[05:17:26] <chr0n1c> yes.. waiting for this program to cut is driving me insane
[05:17:35] <Jymmm> in that pile of machenry junk or in a bin?
[05:17:48] <ds3> it in a bin
[05:17:55] <ds3> 3 bins stacked on top of each other
[05:18:02] <chr0n1c> anyone want 3 vfd's ans a button matrix out of a royal cash register?
[05:18:05] <chr0n1c> and*
[05:18:05] <Jymmm> oh, not on one of the shelve.s
[05:18:17] <ds3> there were other steppers with encoders on them but I only got the ones with US digital
[05:18:34] <Jymmm> ds3: how long ago?
[05:18:51] <ds3> around Feb I think
[05:19:02] <chr0n1c> i got the power supply... and fuse block.. battery compartment... a 6 pos. key switch... and $1.05 in cash out of it
[05:19:17] <Jymmm> oh, ok. If you see any mre let me know. I think he's only open weekdays iirc
[05:19:18] <chr0n1c> oh.. and a smal solenoid... that pulls when power is applied
[05:19:41] <ds3> Sat too, the last i checked
[05:19:59] <ds3> arrgggg this wiki is frustrating me
[05:20:07] <Jymmm> ds3: which model# encoders did you get?
[05:20:13] <jmkasunich> ds3: whats the matter?
[05:20:42] <ds3> jmkasunich: I can't figure out how to create a page (want to upload my musing on the Lathe canned cycles)
[05:21:05] <jmkasunich> two approaches
[05:21:10] <ds3> Jymm: E2-400-250
[05:21:20] <jmkasunich> 1) find a page that your stuff fits on, and add it there
[05:21:35] <jmkasunich> 2) find a page that your stuff would be linked from, and add a link there
[05:21:48] <jmkasunich> use "pageindex" at the bottom to look for sensible places
[05:21:55] <jmkasunich> I think there are already some lathe related pages
[05:22:01] <jmkasunich> if you want to add, just do it
[05:22:02] <ds3> so it will let me put a page in once i add a link?
[05:22:19] <ds3> the problem is I can't seem to find an "add" button
[05:22:37] <jmkasunich> if you want a new page, edit the page you are linking from.... any text in SillyMixedCase is assumed to be a page name
[05:22:48] <jmkasunich> when you save the edit, the SillyMixedCase will have a ? after it
[05:23:04] <jmkasunich> click the ? and it will take you to a blank page that will become the SillyMixedCase page
[05:23:23] <ds3> ah... that's what I missed.
[05:23:24] <jmkasunich> once there is content, the ? goes away and the SillyMixedCase text on the original page becomes a link
[05:27:59] <ds3> "Describe the new page here." is where i put the contents, right?
[05:28:28] <jmkasunich> the big white box?
[05:29:56] <jmkasunich> ds3: the content goes in the big white box, I don't recall what is in there, might be something like "describe the new page here", just delete it and put your stuff in
[05:30:50] <ds3> cool. thanks.
[05:40:17] <Jymmm> ds3: Do you know the model# of the encoders you got?
[05:41:06] <ds3> Jymmm: eh? not sure what you are looking for... all I have is the number I gave you earlier
[05:41:36] <Jymmm> Oh I missed it, helping custoemrs and all
[05:42:23] <ds3> ohhhh okie
[05:42:33] <ds3> here it is again then:
[05:42:38] <ds3> Jymm: E2-400-250
[05:42:43] <Jymmm> thanks
[05:43:33] <Jymmm> 400 CPR, 250 is the shaft diameter
[05:44:20] <ds3> was able to only find 2 matched motors so this will be a lathe application :/
[05:44:44] <ds3> okay, my Haas lathe info is in the wiki... feel free to chew it up and spit it back out
[05:45:46] <Jymmm> The "Data Rate" Column is why I was wondering if the optics in mice are "fast enough"
http://www.vishay.com/ir-transceivers/
[05:45:58] <Jymmm> being so cheap and all.
[05:46:24] <ds3> eh?
[05:46:44] <ds3> these are all for IRDA applications
[05:46:57] <Jymmm> and your point is?
[05:47:11] <ds3> they would not be represenative of what's inside mice
[05:47:13] <Jymmm> ds3: What, you think I know wht I'm talking about ??? lol
[05:47:36] <Jymmm> I have no idea at what speed the IR tranceiver in a mouse is
[05:47:43] <ds3> you were talking about mice... and unless you have moved onto wireless ones....
[05:51:48] <chr0n1c> 9600 bps?
[05:51:51] <chr0n1c> kbps*
[05:51:56] <Jymmm> No, just the transceiver inside
[05:52:29] <ds3> the limitation is most likely from the amps on the phototransistor
[05:52:37] <Jymmm> ds3: In mice there is a IR LED and a IR receiver
[05:53:28] <Jymmm> yeah. but I hvne't grasped my mind arounfd the whole rotary encoder CPR, Ir thing yet
[05:53:53] <chr0n1c> OH! check this out....
[05:53:56] <ds3> Jymmm: yes, but you can't just pick one and call it 'typical'... a remote control system has a IR LED and IR receiver and those can be as slow as 22KHz
[05:54:15] <chr0n1c> we got a used summagraphics 24x26 digitizer at work!
[05:54:25] <chr0n1c> i got it set up with mastercam/autocad now...
[05:54:30] <Jymmm> ds3: soe of those on that page are 16Mbps
[05:54:33] <ds3> Mmmmmmm mastercam
[05:54:35] <chr0n1c> and i am the only person who knows how to run it ;)
[05:55:02] <chr0n1c> i had to re-wind/re-solder the coil in the 16 button puck...
[05:55:06] <chr0n1c> works liek a chap now
[05:55:10] <chr0n1c> champ*
[05:55:38] <ds3> what version of mastercam?
[05:55:41] <chr0n1c> and i had to order two different cables from two different stores to get it hooked up without 83 adapters... lol
[05:55:55] <chr0n1c> they are running v9 at the shop
[05:56:33] <chr0n1c> i only have a 12x12 digitizer hewre.. it's just a toy compared to the 24x26.. it's huge...
[05:56:42] <chr0n1c> 24x36*
[05:56:43] <ds3> digitizer as in a probe or?
[05:56:58] <chr0n1c> summagraphics microgrid II
[05:57:08] <chr0n1c> digitizer tablet...
[05:57:16] <chr0n1c> with a 16 button crosshair puck
[05:57:30] <chr0n1c> for digitizing blueprints and drawings
[05:57:50] <chr0n1c> or for finding the radii on reproduction car parts... to reverse engineer some dies for them :D
[05:57:56] <ds3> heh
[05:58:04] <ds3> why not a laser scanner?
[05:58:19] <chr0n1c> well.. i don't think they wanna spend 30 grand
[05:58:38] <chr0n1c> i been thinking about tryin to build one of the homebrew ones for it
[05:58:41] <ds3> aren't there cheaper ones?
[05:58:46] <chr0n1c> and charge them to scan stuff on my own time
[05:59:09] <ds3> trying to do that myself
[05:59:15] <chr0n1c> i dunno.. i haven't looke dmuch
[05:59:26] <chr0n1c> but they are oldschool
[05:59:41] <chr0n1c> we still have a 10 foot bed planer from like 1813
[05:59:46] <chr0n1c> er uh 1913
[05:59:50] <ds3> planers are cool
[06:00:12] <ds3> makes a great workbench ;)
[06:00:16] <chr0n1c> it used to run on leather belts from the ceiling.. they added a huge electric motor to it and a transmission from a 60's manual truck
[06:00:33] <chr0n1c> we use it to make rocker molding dies n shit
[06:00:59] <ds3> who gets to grind the bits?
[06:01:07] <chr0n1c> they want me to run it.. but that's a lot of steel in that table to be slingin around.. i let the old man do it
[06:01:11] <chr0n1c> it's his machine
[06:01:24] <chr0n1c> he;s taken it with him to three different shops he has worked at over the years
[06:01:41] <chr0n1c> we have the bits wire burnt ;)
[06:01:47] <chr0n1c> or hand grind them
[06:01:53] <chr0n1c> i did a few on the surface grinder
[06:02:28] <chr0n1c> wire burn it out of tool steel.. and some chip breaker relief.. good to go
[06:02:30] <ds3> do they even fit on a magnetic chuck? ;)
[06:02:32] <chr0n1c> no grinding really
[06:02:55] <chr0n1c> well.. we do half bits at a time.. 2 make a 3 or 4 inch bit
[06:03:07] <chr0n1c> so 1.5 or two inches per side
[06:03:21] <chr0n1c> and i grind em seperate
[06:03:39] <chr0n1c> it's amazing what that paner can do
[06:03:52] <chr0n1c> it has the tiniest bit of chatter that gets polished out
[06:03:56] <ds3> has anyone crash it?
[06:03:59] <chr0n1c> and the dies are done ;)
[06:04:06] <chr0n1c> noo...
[06:04:14] <chr0n1c> that old man has been running it for 30 years at least
[06:04:22] <chr0n1c> he knows it like his right hand
[06:04:26] <chr0n1c> lol
[06:04:38] <chr0n1c> it looks fun
[06:04:48] <chr0n1c> it even has a 2 axis dro on the head
[06:05:15] <chr0n1c> maybe he crashed it when he was green
[06:05:31] <chr0n1c> i haven't heard any stories tho
[06:06:25] <chr0n1c> we have a shaper too.. a smaller one but it's not wired up.. makes a great work vise
[06:06:35] <chr0n1c> that would be fun to cnc with emc2
[06:08:43] <ds3> i could use a a small shaper
[06:09:26] <chr0n1c> what do ya make?
[06:09:41] <ds3> random stuff... mine is a hobby show
[06:09:46] <jmkasunich> about 8-9 years ago when I was just getting into metalworking, I passed up a chance to get a South Bend 7" shaper for $250
[06:09:51] <jmkasunich> been kicking myself since
[06:09:59] <jmkasunich> they go for 2-3 times that
[06:10:10] <chr0n1c> there is a lot of steel in them even if you dont use it
[06:10:25] <chr0n1c> and cool bearings and ballscrews sometimes
[06:10:31] <chr0n1c> and gears and handles
[06:10:36] <ds3> i saw one run and it was fascinating
[06:10:51] <chr0n1c> i saw a video somewhere in the net...
[06:10:53] <chr0n1c> i never ran one
[06:10:57] <chr0n1c> but i get the idea...
[06:11:03] <chr0n1c> it's liek the planer sort of
[06:11:07] <ds3> ds3 is now known as ds2
[06:11:28] <chr0n1c> a lathe for flat stock of sorts
[06:13:34] <chr0n1c> i wonder what kind of resolution i need to copy old germanmedals from a picture...
[06:13:59] <chr0n1c> i haven't been getting very good results from the pics i found so far
[06:14:34] <chr0n1c> thats wher ethe laser sacanner would come in handy
[06:14:37] <chr0n1c> !
[06:22:23] <ds2> finally back to my native nick
[06:26:59] <ohiopctechDOTcom> ;)
[06:29:01] <ohiopctechDOTcom> i need to get a guitar tuner and see what notes the feedrates are making and write an emc2 g-code song
[06:29:18] <ohiopctechDOTcom> then sample it and add some scratching..
[06:29:38] <ohiopctechDOTcom> anyways...

[11:12:31] <Rugludallur> morning, hmm although it's almost noon here
[11:15:39] <alex_joni> hi there
[11:16:45] <Rugludallur> got all day set up for testing thc/plasma, and got the video camera ready :)
[11:16:56] <alex_joni> perfect
[11:17:04] <alex_joni> that's the proper attitude :D
[11:17:34] <Rugludallur> alex_joni: yeah, just finished building a new computer box (control box) with full shielding and floating earth
[11:18:25] <Rugludallur> alex_joni: now I can bring 30.000V sparking to 10cm off the monitor and it doesn't even flicker so I'm pretty sure I won't get any problems from RF or grounding issues this time around
[11:18:50] <alex_joni> great
[11:19:24] <Rugludallur> what are you up to on a sunday ?
[11:20:01] <alex_joni> right now feeding
[11:20:16] <alex_joni> was pondering getting out for some tennis
[11:21:25] <Rugludallur> alex_joni: sounds like a great way to spend a sunday
[11:21:58] <alex_joni> weeeell, not that thrilled though
[11:22:10] <alex_joni> I already went yesterday, after a long while
[11:22:16] <alex_joni> and did some running afterwards
[11:22:38] <alex_joni> so today.. I'm .. uhm.. a bit sore
[11:23:21] <Rugludallur> alex_joni: hmm just give it 10m and then you won't even notice :)
[11:25:40] <alex_joni> yeah, it's those 10m I'm worried about
[11:25:44] <alex_joni> not really worried..
[11:25:58] <alex_joni> but it's just way nicer to slack in bed with a laptop on my lap
[11:28:31] <Rugludallur> lol
[11:28:50] <alex_joni> wouldn't you agree?
[11:32:14] <Rugludallur> yeah,, but once you get over it ....
[11:37:41] <Rugludallur> hey Martin
[11:37:53] <martn_lundstrom> Hello
[11:38:00] <martn_lundstrom> how are you?
[11:38:28] <martn_lundstrom> martn_lundstrom is now known as martin_lundstrom
[11:38:31] <Rugludallur> great, prepping up for a whole day of plasma testing
[11:38:39] <martin_lundstrom> cool
[11:38:50] <Rugludallur> martin: will make some videos
[11:39:04] <martin_lundstrom> and the config seeemes to be working?
[11:39:10] <martin_lundstrom> nice!
[11:39:22] <Rugludallur> martin: everything seems to work pretty good, but I need to tune the THC
[11:39:32] <martin_lundstrom> ok
[11:39:49] <martin_lundstrom> too much up and down?
[11:40:06] <Rugludallur> martin_lundstrom: velocity v.s deadband vs height
[11:40:19] <martin_lundstrom> hmmm
[11:41:28] <martin_lundstrom> I mounted the Z axis on my second table.
[11:41:50] <Rugludallur> martin_lundstrom: got it moving and all ?
[11:42:29] <martin_lundstrom> I did not yet connect the computer
[11:42:50] <martin_lundstrom> more or less next step
[11:43:08] <Rugludallur> martin_lundstrom: :)
[11:44:03] <martin_lundstrom> I wish you good luck with the testing!!
[11:44:20] <Rugludallur> martin_lundstrom: great, thanks, I will make sure to let you know when I have videos
[11:45:22] <martin_lundstrom> thanks
[11:59:59] <alex_joni> bbl guys
[12:00:10] <alex_joni> Rugludallur: decided to try it out afterall

[14:48:38] <skunkworks> Is backlash comp working as expected in the latest release?
[14:48:46] <skunkworks> 'as expected' ;)
[15:04:16] <cradek> I think ray tested it and it worked ok - I haven't tested it yet
[15:05:16] <lerneaen_hydra> there's still the maxvel*2 effect in it, right?
[15:06:30] <cradek> yes, or possibly accel, I don't remember the details
[15:10:07] <skunkworks> Thanks. It was in reference to this

[15:13:26] <cradek> jeez
[15:13:45] <skunkworks> ah - the good old days ;)
[15:13:46] <cradek> I wonder if they found a way to thread the core by machine, or if it was all hand threaded
[15:14:11] <cradek> I thought a lot of core was threaded by hand, but I don't know for sure how they did it in the later days
[15:14:37] <skunkworks> I wonder if a convetional 'loom' would work with some mods
[15:15:52] <skunkworks> I can't belive it actually worked at all ;)
[15:16:02] <lerneaen_hydra> 2mb in ring memory O_O

[15:34:28] <giacus> so, I'll need to ask something about that to you :D
[15:34:40] <cnc_engineer123> i wanna get some help regarding compiling emc2
[15:34:45] <giacus> I think we'll use emc2 for that :P
[15:34:48] <giacus> Hi cnc_engineer123
[15:35:15] <skunkworks> Cool
[15:35:22] <giacus> :P
[15:35:24] <skunkworks> cnc_engineer123: ask away
[15:36:40] <cnc_engineer123> i am getting some errors during compilation process
[15:36:57] <giacus> cnc_engineer123: switch to win vista!!
[15:36:59] <giacus> :D
[15:37:06] <skunkworks> can you post the errors on pastebin.ca?
[15:37:14] <giacus> copyright attitude :D
[15:37:24] <skunkworks> crap - biab
[15:38:16] <giacus> some errors?
[15:38:22] <giacus> what errors ?
[15:38:52] <giacus> someone need to know that in order to help!
[15:38:55] <giacus> :P
[15:39:01] <giacus> kidding ..
[15:39:03] <giacus> :D
[15:39:11] <cnc_engineer123> when i issue the make command, it seems make is recursively making the compile process
[15:40:19] <giacus> no much more info, about compiler you're using and other ?
[15:41:12] <giacus> ok ..
[15:41:23] <giacus> looking at the sphere ..

[15:42:44] <giacus> did you seen him lately ?
[15:43:47] <cnc_engineer123> i have emc2 live CD installed with ubuntu ver 6.06. Then I downloaded the dependency packages to compile EMC2 using the command "apt-get install build-dep emc2"
[15:44:30] <giacus> that's ok
[15:45:03] <giacus> paste the errors on pastebin as skunkworks suggest
[15:45:14] <giacus> :D
[15:45:44] <giacus> be sure you did apt-get update/upgrade too

[18:32:25] <Skullworks_PGAB> cradek around?
[18:33:22] <ohiopctechDOTcom> if you were going to make rails for a lathe x-slide to ride on..would you use 3/4" W1 or o1 drill rod?
[18:33:34] <ohiopctechDOTcom> *i ordered some w1...
[18:33:41] <ohiopctechDOTcom> gonna try that...
[18:34:22] <Skullworks_PGAB> I have an idea for the tool setting issues that have been in the recent email digest.
[18:34:54] <alex_joni> Skullworks_PGAB: go on, he'll read when he gets back
[18:35:04] <Skullworks_PGAB> W1 vrs O1 is fine - just wipe it down with some light oil before storage
[18:35:18] <Skullworks_PGAB> W1 rusts quick
[18:35:24] <ohiopctechDOTcom> yeah...
[18:35:28] <Skullworks_PGAB> OK Alex
[18:36:10] <Skullworks_PGAB> topic was in response to tool setting and loading values into the tool table using probing
[18:36:17] <ohiopctechDOTcom> i shoulda ordered stainlesS...
[18:36:26] <Skullworks_PGAB> NOT SS
[18:36:32] <ohiopctechDOTcom> NO?
[18:36:50] <Skullworks_PGAB> SS is softer unless you go 400 series
[18:37:11] <Skullworks_PGAB> and 400 is magnetic and will slightly rust too
[18:37:12] <ohiopctechDOTcom> oh..what about black oxide'ing them? should help right?
[18:37:37] <ohiopctechDOTcom> the w1...
[18:37:51] <Skullworks_PGAB> Drill rod comes centerless ground in about 3ft lengths standard
[18:37:58] <ohiopctechDOTcom> i build machines all the time but we usually pay a designer to draw them and do the steel selection.. ;)
[18:38:06] <Skullworks_PGAB> its very straight
[18:38:13] <ohiopctechDOTcom> yeah i got 2 3 ft lengths of it
[18:38:22] <Skullworks_PGAB> VERY on size
[18:38:43] <Skullworks_PGAB> only thing better would be CPO bar
[18:39:02] <Skullworks_PGAB> (Hydrolic cylinder rod
[18:39:12] <ohiopctechDOTcom> ahh..
[18:39:24] <Skullworks_PGAB> ground, polished and hardchromed
[18:39:51] <Skullworks_PGAB> made from half hard carbon steel
[18:40:04] <Skullworks_PGAB> 1045-1065
[18:40:39] <ohiopctechDOTcom> my indicator is coming tomorrow.... mo more out of tram z axis!
[18:40:50] <Skullworks_PGAB> anyway - for the tool setting issue...
[18:40:58] <ohiopctechDOTcom> it cuts on a 10 degree angle...
[18:41:02] <ohiopctechDOTcom> for now*
[18:41:37] <Skullworks_PGAB> I think its time to expand beyond the NGC spec as they left out some items
[18:42:30] <Skullworks_PGAB> Specifically - G10 L1, which is used to load values into tool offset locations
[18:42:55] <ohiopctechDOTcom> there is a message on my machine... "call me back dick!" with no number.. and i don't recognize the voice
[18:43:12] <ohiopctechDOTcom> ha!
[18:43:34] <skunkworks> well I got a replacement fan for the server mounted, lets say it needed some modifying.
[18:44:06] <Skullworks_PGAB> G10 L2 is allready supported for loading values into G54-G59 and the "extras".
[18:44:28] <ohiopctechDOTcom> did everyone check this out ..
http://ohiopctech.com/cnc/ironcross/
[18:44:53] <ohiopctechDOTcom> it's nothing special.. but emc2 cut it
[18:45:47] <Skullworks_PGAB> that done with an engraving cutter?
[18:46:05] <ohiopctechDOTcom> a center drill
[18:46:12] <ohiopctechDOTcom> 1/8 shank .040 drill point
[18:46:22] <ohiopctechDOTcom> number 2
[18:47:01] <Skullworks_PGAB> 2 - your sure it isn't a 1?
[18:47:06] <ohiopctechDOTcom> i've just always found i like the cut of the tip of the centerdrill better than and engraving cutter
[18:47:15] <ohiopctechDOTcom> ehh... maybe 1
[18:47:20] <ohiopctechDOTcom> i thought it was a 2 though
[18:47:51] <Skullworks_PGAB> #2 has 3/16" body ( I use them by the dozen)
[18:48:57] <Skullworks_PGAB> I get mine custom made with 90 or 82 degree angle vrs 60
[18:49:26] <ohiopctechDOTcom> that may be right!
[18:49:34] <Skullworks_PGAB> leaves the perfect chamfer for tapping up to a #8 screw
[18:49:44] <ohiopctechDOTcom> i never said i always think about what i am typing before i type.. lol
[18:50:00] <ohiopctechDOTcom> yeah... i use the center drills for more than just center drilling
[18:50:10] <ohiopctechDOTcom> i always use them for engraving...
[18:50:22] <ohiopctechDOTcom> the bigger ones work good for bigger letters also
[18:50:30] <Skullworks_PGAB> * Skullworks_PGAB runs to check his penne
[18:50:36] <ohiopctechDOTcom> they stay sharp longer than engraving cutters
[18:50:40] <ohiopctechDOTcom> even if they are carbide
[18:53:29] <skunkworks> booting
[18:57:50] <Skullworks_PGAB> ohiopctechDOTcom> they stay sharp longer than engraving cutters <<< in your application.
[18:58:19] <ohiopctechDOTcom> riiight
[18:59:07] <Skullworks_PGAB> thats because a C-drill has better tip support and can take more abuse - like a high T.I.R. spindle (wobbly)
[18:59:49] <ohiopctechDOTcom> they tried to mave me use the 3 sided engraving cutters... they would break halfway through the job... always
[19:00:06] <ohiopctechDOTcom> when i was getting paid to engrave steel guages*
[19:00:17] <ohiopctechDOTcom> gauges*
[19:00:22] <Skullworks_PGAB> I used single flute 42 degree cutters with a .007 flat on the tip
[19:00:47] <Skullworks_PGAB> 24,000 rpm
[19:01:12] <Skullworks_PGAB> .014" depth in 6061 or 6063
[19:01:40] <Skullworks_PGAB> tool lasted 2-3 weeks - approx 100 hrs cutting time.
[19:01:56] <ohiopctechDOTcom> i usually cut between .003" and .010" with the #1 center drill
[19:02:47] <ohiopctechDOTcom> i do plastic and wood and metals with em
[19:03:02] <Skullworks_PGAB> I needed a deep but narrow cut
[19:03:06] <lerman_> lerman_ is now known as lerman
[19:03:10] <ohiopctechDOTcom> it even worlks great for a tiny endmil in ofter materials
[19:03:22] <ohiopctechDOTcom> softer*
[19:03:39] <Skullworks_PGAB> panels got 1 coat primer - 2 coats base color then the engraving was paint filled
[19:04:00] <Jymmmmmmm> ?

[19:07:51] <ohiopctechDOTcom> i'm all over the logs babbling
[19:07:52] <ohiopctechDOTcom> hehe
[19:10:56] <skunkworks> your cronic - right?
[19:11:10] <skunkworks> * skunkworks doesn't look at ip
[19:11:11] <ohiopctechDOTcom> ya
[19:11:41] <skunkworks> hmmm is one proccessor is running 105 - and one is running 120deg
[19:12:01] <Skullworks_PGAB> same brand/model fans?
[19:12:13] <skunkworks> same heatsink - different fans now
[19:12:18] <ohiopctechDOTcom> does one do file system and one do graphics?
[19:12:27] <ohiopctechDOTcom> fans dif speeds?
[19:12:28] <skunkworks> windows 2k
[19:12:37] <skunkworks> I think everything does everything
[19:13:24] <ohiopctechDOTcom> if the ubuntu live cd would boot on my xbox... i could do usb-parport adapters ;)
[19:13:37] <skunkworks> no - you can't
[19:13:46] <ohiopctechDOTcom> oh..
[19:13:48] <ohiopctechDOTcom> :(
[19:13:58] <skunkworks> sorry
[19:13:58] <ohiopctechDOTcom> it already runs linux... a dynebolic live cd
[19:14:00] <Skullworks_PGAB> usb-paraport is useless for EMC
[19:14:23] <ohiopctechDOTcom> i didn't know if there was drivers for the adapter in linux
[19:14:36] <ohiopctechDOTcom> that would make it a real parport.. would be nice
[19:14:56] <Skullworks_PGAB> but Bert's 1st gen USBCNC card used EMC1 embeded
[19:15:09] <ohiopctechDOTcom> x(emc2)box
[19:15:27] <Skullworks_PGAB> real for printing - not real time capable.
[19:16:04] <ohiopctechDOTcom> intersting
[19:16:13] <ohiopctechDOTcom> got a link i could check it out?
[19:16:20] <Jymmm> Skullworks_PGAB: I didnt see mention of a pic or url for the panels you mentioned
[19:16:25] <ohiopctechDOTcom> i got google nvm
[19:16:46] <Skullworks_PGAB> the panels I engrave?
[19:17:23] <Jymmm> you said panels primer paint and backfill, we want pics!!!
[19:17:26] <Skullworks_PGAB> old stuff for Hughes Aircraft Sat division?
[19:17:36] <skunkworks> with case on - 111f and 122f
[19:18:18] <Jymmm> Alright, I must be missing a jumper, just changed the CMOS battery yesterday adn still lost all settings.
[19:19:23] <ohiopctechDOTcom> battery dead?
[19:19:38] <Skullworks_PGAB> I need to get the jumper settings for that Dell Dual CPU server I was working on - 2nd CPU stays cold
[19:20:17] <Jymmm> cold as in not being used?
[19:20:26] <Skullworks_PGAB> guess so
[19:20:41] <Skullworks_PGAB> I loaded Ubunto server on it
[19:20:45] <Jymmm> check BIOS settings, and make sure you have the latest BIOS too
[19:20:54] <Skullworks_PGAB> so no GUI tools yet
[19:21:12] <Jymmm> On my dual, I had to add in linux dual suppport
[19:21:26] <Jymmm> but desktop not server
[19:21:26] <Skullworks_PGAB> for server?
[19:21:30] <Jymmm> ubuntu that is
[19:22:24] <Jymmm> In emc mode, I got 1 cpu and 1GB ram, in i686 mode, I got 2 cpu and 2 GB ram
[19:22:33] <Skullworks_PGAB> I should just wipe the drive - do a W2K load for hardware testing - then wipe it again
[19:23:09] <Skullworks_PGAB> Jym - thats just strange?
[19:23:40] <Jymmm> Skullworks_PGAB: Nah, cradek found that it's intentionally set that way the RT kernel doens't support 2GB ram
[19:24:05] <Skullworks_PGAB> but what about 2nd CPU
[19:24:14] <skunkworks> it can't use anything over 1gb
[19:24:29] <Skullworks_PGAB> good to know
[19:24:59] <Skullworks_PGAB> * Skullworks_PGAB wonders if that is in the Wiki FAQ
[19:25:01] <Jymmm> Skullworks_PGAB: No support for it unless I use experimental SMP RT kernel
[19:25:16] <Jymmm> linuxcnc.org/experimental
[19:25:49] <Skullworks_PGAB> I have a dual slot 1 and a pair of pIII-600's I would love to try
[19:26:23] <Skullworks_PGAB> put RT on #2 and X and gui/frontend on #1
[19:26:32] <Jymmm> I'm running on a Tyan S2518 mobo with dual 1GHz and 2GB ram.... it flys when I boot into that kernel
[19:27:11] <Jymmm> P3 that is

[19:38:49] <ohiopctechDOTcom> nice box
[19:39:05] <Skullworks_PGAB> old box
[19:39:31] <Jymmm> Hmmmm they designed the PS connector opposite side from DIMMs
[19:39:41] <anonimasu> hi
[19:39:48] <Jymmm> anonimasu: !!!
[19:39:54] <anonimasu> Jymmm: did you figure anything out
[19:39:59] <Skullworks_PGAB> still using #3 - with a pile of 74GB Cheetah drives
[19:40:06] <Jymmm> anonimasu: Besides that I'm nuts?
[19:40:18] <anonimasu> yeah
[19:41:28] <Jymmm> anonimasu: No, was thinking about it all night at work. I cna get encoders for $20/ea but they only do 300CPR, ds2 suggested hitting the local machine surplus and maybe find some steppers with encoders there, he got some make if FEB

[19:43:11] <Jymmm> Then I'd have 3 paraports total
[19:53:33] <Skullworks_PGAB> * Skullworks_PGAB has been shooting in the house, pics that is...
[19:54:04] <Jymmm> Yeah, blame the holes on the camera
[19:54:22] <Skullworks_PGAB> shot two of the engraved panels
[19:54:54] <Skullworks_PGAB> no - holes were made by a CNC Strippit pucnh
[19:55:22] <Jymmm> I meant shooting the house
[19:57:18] <Skullworks_PGAB> not put any holes in the house since before Y2K
[19:58:43] <Skullworks_PGAB> Ubuntu - is not windows... I just plugged in my camera for giggles and everything just worked.
[19:59:39] <ohiopctechDOTcom> * ohiopctechDOTcom is getting a visit from the hot blonde chick soon ;)
[20:01:32] <Skullworks_PGAB> * Skullworks_PGAB thinks two words - Web cam...

[20:05:52] <anonimasu> :)
[20:09:05] <alex_joni> hmm.. I leave for half an hour, and this happens
[20:09:07] <alex_joni> :/
[20:09:19] <lerneaen_hydra> alex_joni: exactly
[20:09:35] <alex_joni> I would have expected a webpage with applet by now
[20:09:38] <alex_joni> streaming
[20:09:43] <lerneaen_hydra> TMI!
[20:09:54] <lerneaen_hydra> I do *not* want to know what it's streaming
[20:10:18] <anonimasu> alex_joni: what?
[20:10:27] <alex_joni> anonimasu: who?
[20:10:37] <anonimasu> alex_joni: WHAT?!
[20:10:38] <anonimasu> :D
[20:10:43] <alex_joni> ok.. what?
[20:10:51] <anonimasu> 22:15 < alex_joni> I would have expected a webpage with applet by now
[20:11:02] <alex_joni> yeah, from ohiopctechDOTcom
[20:11:26] <anonimasu> ah ok
[20:11:43] <alex_joni> not really.. but let's leave it at that
[20:12:30] <Skullworks_PGAB> Alex
[20:12:39] <alex_joni> Skullworks_PGAB: yes..
[20:13:22] <Skullworks_PGAB> what do you think about a tool setting macro that could load an offset directly into the tool table?
[20:14:00] <alex_joni> hmm.. not sure
[20:14:13] <alex_joni> it depends what you understand under tool table
[20:14:13] <alex_joni> if it
[20:14:26] <alex_joni> if it's the current definition (file with numbers in it), then I'm not so sure
[20:14:39] <Skullworks_PGAB> this is for users who are running collets or other non-repeatable tooling
[20:14:44] <alex_joni> if it's emc's internal representation of it.. then yeah
[20:15:05] <anonimasu> I guess it dosent matter if you use the table or not.. really it's the offsets you want to set..
[20:17:38] <Skullworks_PGAB> well - IIRC the tool table is a file loaded during start up
[20:18:02] <Skullworks_PGAB> offset changes require file to be reloaded
[20:19:02] <alex_joni> details I say
[20:24:06] <Skullworks_PGAB> well - I propose we add support for G10 L1
[20:24:37] <alex_joni> Skullworks_PGAB: if you want this to really stick, I suggest mailing list or feature request
[20:24:45] <Skullworks_PGAB> which does for tools what G10 L2 does for G54-G59...
[20:24:51] <alex_joni> (not that people don't read this.. but it usually gets forgotten in 2-3 weeks)
[20:25:09] <Jymmm> alex_joni: what did you say?
[20:25:22] <alex_joni> Jymmm: can't remember
[20:25:26] <alex_joni> who are you anyways?
[20:25:28] <Jymmm> ROTF
[20:25:36] <Jymmm> alex_joni: I'm you, I think
[20:25:48] <Jymmm> No wait....
[20:26:00] <Jymmm> I'm the one your momma warned you about
[20:27:34] <alex_joni> you blonde, apparently stupid, and wanna get pregnant by me?
[20:27:52] <Jymmm> YES! YES! OH GAWD! YES!
[20:31:08] <alex_joni> * alex_joni shrugs
[20:31:31] <Jymmm> did your mom really tell you that?
[20:31:49] <alex_joni> lol, no
[20:32:10] <alex_joni> btw, you gotta hurry if you mean it..
[20:32:15] <Jymmm> I wouldn't be surprised.... Mom just looking out for her boy is all
[20:32:20] <Jymmm> lol
[20:32:24] <Jymmm> ROTFLMAO
[20:32:25] <alex_joni> I'm less than a month away from getting married :P
[20:32:39] <alex_joni> Jymmm: ROTFL
[20:32:41] <Jymmm> CONGRATS
[20:32:45] <alex_joni> yeah, thanks
[20:33:14] <Skullworks_PGAB> OK - I'm feeling realy stupid... What do people use for an FTP client in Breezy?
[20:33:22] <Jymmm> Sounds like you are REALLY enthiusiastic about getting hitched
[20:33:22] <alex_joni> cli
[20:33:34] <Jymmm> Skullworks_PGAB: ftp
[20:33:42] <Jymmm> do you mean gui?
[20:33:44] <Skullworks_PGAB> I can pull down stuff via Firefox...
[20:33:56] <Skullworks_PGAB> but to put
[20:34:05] <Jymmm> shell ftp
[20:34:17] <Skullworks_PGAB> hmm
[20:34:29] <Skullworks_PGAB> nix cli is rusty...
[20:34:32] <Skullworks_PGAB> but OK
[20:34:40] <Jymmm> lol, try M$ CLI
[20:35:24] <alex_joni> ha
[20:35:34] <Skullworks_PGAB> ha - I'm down right scary in an M$ enviroment...
[20:35:37] <alex_joni> I got nix tools on m$ cli
[20:35:45] <Skullworks_PGAB> I have the power of the dark side
[20:35:46] <alex_joni> find & grep & co
[20:36:02] <Jymmm> I got wget and less too
[20:36:22] <Skullworks_PGAB> M$ needed less
[20:36:30] <alex_joni> & more
[20:36:34] <Skullworks_PGAB> pico would be nice too
[20:36:36] <Jymmm> tail too
[20:36:43] <alex_joni> M$ always needs more
[20:36:45] <alex_joni> lol
[20:37:05] <Skullworks_PGAB> M$ needs liposuction...
[20:37:11] <alex_joni> tmi
[20:37:13] <Jymmm> more or less
[20:37:24] <alex_joni> in a world without walls & fences..
[20:37:33] <alex_joni> who needs gates & windows
[20:37:41] <Jymmm> just shotguns
[20:37:53] <Skullworks_PGAB> but I had the camera on the emc box - figured I'd just move the pic to my ISP
[20:38:20] <alex_joni> Skullworks_PGAB: ISP doesn't do ssh?
[20:38:53] <Skullworks_PGAB> Quote from Firefly/Serenity "Sure would be nice if we had some grenades..."
[20:39:11] <Skullworks_PGAB> never tried
[20:39:22] <Skullworks_PGAB> its all linux boxes
[20:39:48] <Skullworks_PGAB> have cgi-bin support if I care to use it
[20:40:09] <Skullworks_PGAB> but I'm useless with Perl
[20:40:22] <Skullworks_PGAB> nearly useless with PHP
[20:40:28] <robin_sz> perl rocks
[20:40:44] <Skullworks_PGAB> it does
[20:40:57] <Skullworks_PGAB> and I would love to take a class in it
[20:41:16] <robin_sz> theres a really good online tutorial
[20:41:38] <Skullworks_PGAB> but only places that teach it local are high priced private colleges
[20:42:50] <Skullworks_PGAB> nother stupid question - do I need to "unmount" the camera, or being usb can I just yank the cord?
[20:46:08] <Jymmm> on e way to find out
[20:46:30] <lerneaen_hydra> Skullworks_PGAB: is it a mass-storage type camera or PTP camera?
[20:52:36] <Skullworks_PGAB> usb mass store
[20:52:53] <Skullworks_PGAB> have ftp running in term win
[20:53:21] <Skullworks_PGAB> I'm in proper directory of ISP
[20:53:34] <alex_joni> put filename
[20:53:40] <alex_joni> or put /path/to/filename
[20:53:50] <Skullworks_PGAB> now must figure the right file source path...
[20:55:59] <picnet> Greetings.

[20:56:48] <alex_joni> hey picnet
[20:57:32] <picnet> just shifting from my laptop install of mach3 (which shall not be mentioned here) to my old bdi machine which is now running emc2 and the world is brighter than normal.
[20:57:53] <alex_joni> picnet: no worries about mentioning mach3 in here
[20:57:59] <alex_joni> we're tolerant people ;)
[20:58:05] <picnet> ;)
[20:58:08] <alex_joni> but it's good you've seen the light :P
[20:58:28] <alex_joni> picnet: so you're liking emc2?
[20:58:36] <picnet> i used emc ages ago, this was before the axis display etc
[20:58:58] <Skullworks_PGAB> success
[20:59:13] <picnet> yes, i have a siegx2 mill converted & just plugged in the old cable to this box, configured emc2 and it seems to move around ok :)

[21:00:48] <alex_joni> Skullworks_PGAB: for some values of lucky ;)
[21:00:57] <Skullworks_PGAB> OK a panel pic
[21:01:20] <Jymmm> Skullworks_PGAB: Dont listen to alex_joni, He's whipped
[21:01:21] <Skullworks_PGAB> just held it up at an angle to reduce flash glare
[21:01:37] <alex_joni> Jymmm: not really :P
[21:01:49] <Skullworks_PGAB> * Skullworks_PGAB would not mind getting whipped someday.
[21:02:17] <alex_joni> Skullworks_PGAB: bdsm? lol
[21:02:27] <Skullworks_PGAB> but I have 1800lbs of lead here - no GOLD
[21:02:28] <Jymmm> * Jymmm invites Skullworks_PGAB to /join #bdsm
[21:02:49] <Skullworks_PGAB> womens wantz the flash & cash
[21:03:07] <Jymmm> and the semen
[21:03:17] <Jymmm> biological clock and all
[21:03:23] <Skullworks_PGAB> BSD.. not an emc O/S
[21:03:46] <alex_joni> Skullworks_PGAB: our CVS server runs on BSD :P
[21:04:01] <Skullworks_PGAB> thats fine
[21:04:27] <Skullworks_PGAB> I used to run Gentoo as a bastion host
[21:04:47] <Skullworks_PGAB> keep the crap out
[21:06:09] <Skullworks_PGAB> anyway - here is a pic of a hughes panel before any paint/primer/fill
[21:06:34] <picnet> btw emc2 works fine in a pIII-500 / 384Mb Ram.

[21:07:24] <Skullworks_PGAB> (crap)
[21:07:26] <alex_joni> This is your custom 404 "Not found" Error page.
[21:08:07] <Skullworks_PGAB> http://www.skullworks.net/include/DSCF0277.JPG
[21:08:28] <ohiopctechDOTcom> haha.. no webpage...
[21:08:36] <Skullworks_PGAB> were it not for bad luck...
[21:08:48] <ohiopctechDOTcom> no jave webcam applet
[21:08:53] <ohiopctechDOTcom> java even
[21:10:14] <Skullworks_PGAB> file type is lower case...
[21:10:19] <Skullworks_PGAB> damn
[21:10:39] <Skullworks_PGAB> http://www.skullworks.net/include/DSCF0277.jpg
[21:11:32] <Jymmm> you do that?
[21:11:34] <Skullworks_PGAB> That link actually works...
[21:11:39] <Skullworks_PGAB> yes
[21:11:56] <Jymmm> looks nice, but where's teh mud flap chic?
[21:12:51] <Jymmm> did you do the brushing on the surface?
[21:12:51] <cradek>
[21:13:05] <Skullworks_PGAB> yes
[21:13:22] <Jymmm> Skullworks_PGAB: Can I ask how?
[21:13:35] <Skullworks_PGAB> Timesavers Industrial - wet sander - huge brute
[21:13:47] <Jymmm> ah, ok
[21:13:50] <Skullworks_PGAB> 24" wide belts
[21:13:55] <Jymmm> very symetrical
[21:14:05] <Skullworks_PGAB> power tractor feed
[21:14:05] <ohiopctechDOTcom> my favorite pre-anodizing finish: air-powered DA sander with 120 grit paper
[21:15:00] <Skullworks_PGAB> * Skullworks_PGAB is lazy - just tosses parts into the vibratory wet polisher
[21:15:11] <Jymmm> I hate emissions....
[21:15:20] <robin_sz> nocturnal ones?
[21:15:27] <ohiopctechDOTcom> * ohiopctechDOTcom rofl
[21:15:36] <picnet> * picnet tips hat @ robin.
[21:15:51] <Skullworks_PGAB> Sorry Jym - Move here, We just canned the entire emmissions program
[21:16:08] <Skullworks_PGAB> no more inspections...
[21:16:13] <Skullworks_PGAB> no stickers
[21:16:20] <Skullworks_PGAB> no hassels
[21:16:23] <ohiopctechDOTcom> dayton jsut got rid of thier e-check stuff also
[21:16:31] <Jymmm> Got a ck engine light months ago. Had my friend pull the code from the computer. bad sensor. Replaced the $100 sensor and got awesome gas milage the frist week. The second week I got 100 miles LESS per tank than I have since I'd had the car.
[21:17:17] <Jymmm> Now I have to get a scanner and see if there's a code still set and clear it. or replace the sensor again. Under 1yr warranty.
[21:18:00] <Jymmm> The REALLY suck part is Ford knew about it, but never did a recall, just a notice. bastards and they won't cover it under warranty
[21:18:38] <Jymmm> I'll toss on the old sensor and wait for the ck engine light to come on again, hopefully the mileage will return to normal.
[21:18:51] <Skullworks_PGAB> voluntary recall usually only happen for safety issuse
[21:19:16] <Jymmm> Yeah, true.
[21:19:38] <Skullworks_PGAB> ok - did that CLI ftp...
[21:19:48] <Jymmm> Gas is up to $3.36 now too.
[21:20:19] <Jymmm> HF has a scanner for $40, will work on all ODB II 1996 and newer cars.
[21:20:21] <Skullworks_PGAB> I honestly think the last time I did that in linux I was using a new 80486SX-25
[21:20:27] <Jymmm> lol
[21:21:28] <Skullworks_PGAB> I was anti mouse for a long time
[21:22:19] <Skullworks_PGAB> I could fly thru wordstar using only KYB formatting commands... why take the time to remove your hands from the KYB?
[21:22:46] <Skullworks_PGAB> now I'm kinda GUI'd
[21:23:39] <Skullworks_PGAB> I just wish there was a good cad/cam for linux
[21:24:01] <Skullworks_PGAB> then I could dump most my win boxes
[21:24:36] <ohiopctechDOTcom> i tried mastercam/wine...
[21:24:45] <ohiopctechDOTcom> i forget what happened it was a long itme ago
[21:24:49] <ohiopctechDOTcom> time*
[21:24:52] <ohiopctechDOTcom> i shold try again
[21:25:02] <ohiopctechDOTcom> or crossover office maybe/mastercam
[21:25:26] <ohiopctechDOTcom> hmm...
[21:25:34] <picnet> how do you fix joint <insert favorite joint number here
[21:25:38] <picnet> errors?
[21:25:44] <Skullworks_PGAB> I allready only use OOo
[21:26:03] <ohiopctechDOTcom> OOo?
[21:26:18] <feoc2> picnet steppers or servos?
[21:26:21] <picnet> steppers
[21:26:59] <picnet> steps per mm is 666.67 , velocity was 1073 in mach3, acell 100mm/min.
[21:27:10] <feoc2> only used servo's myself so not read into steppers yet
[21:27:14] <Skullworks_PGAB> Open Office.org
[21:27:16] <picnet> ok
[21:27:17] <ohiopctechDOTcom> ohhh
[21:27:19] <feoc2> might be your missing steps ?
[21:27:33] <ohiopctechDOTcom> i couldn't get base to stop crashing
[21:27:33] <feoc2> best get sombody who knows more about steppers
[21:27:44] <ohiopctechDOTcom> *on windows
[21:27:59] <ohiopctechDOTcom> i was trying to edit the database/invoicing thing from work
[21:29:53] <alex_joni> picnet: joint error means it can't output as many steps as you want
[21:30:18] <alex_joni> picnet: you're getting following errors .. right?
[21:30:22] <picnet> yes
[21:30:32] <alex_joni> picnet: what's your BASE_PERIOD?
[21:30:35] <alex_joni> in the ini..
[21:30:44] <picnet> 5000
[21:30:51] <picnet> opps + 0
[21:30:55] <alex_joni> I hope you missed a 0 there
[21:30:55] <alex_joni> :P
[21:31:00] <alex_joni> right..
[21:31:04] <alex_joni> that means 50 usec
[21:31:06] <picnet> 500mhz box tho.
[21:31:17] <alex_joni> right.. you can probably mess with that a bit
[21:31:27] <alex_joni> try 30 or maybe even 25 if you're brave
[21:31:39] <alex_joni> as you decrease the value you'll see that the pc gets sluggish
[21:31:40] <anonimasu> alex_joni: do you have a good link about robot kins?
[21:31:47] <alex_joni> then it's time to increase it a bit
[21:31:52] <alex_joni> anonimasu: what'cha interested in?
[21:32:26] <alex_joni> picnet: there's an excelent description here:
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl/emcinfo.pl?TweakingSoftwareStepGeneration
[21:32:47] <anonimasu> alex_joni: the calculations involved
[21:32:58] <picnet> thank you, ill go rtfm
[21:33:03] <alex_joni> anonimasu: I suggest you google for D-H
[21:33:08] <alex_joni> denavit-hartenberg
[21:33:41] <anonimasu> ah,..
[21:33:55] <anonimasu> thoose calculations look pretty sane..
[21:34:07] <alex_joni> http://generalrobotics.org/ppp/Kinematics_final.pdf
[21:34:11] <alex_joni> here's an intro
[21:34:18] <robin_sz> Skullworks_PGAB, here ...
[21:34:23] <robin_sz> Skullworks_PGAB, try this:
[21:34:29] <robin_sz> Skullworks_PGAB,
http://sourceforge.net/projects/spork/
[21:34:41] <robin_sz> perl traing docs, very concise and readable
[21:35:19] <Skullworks_PGAB> thanks
[21:35:51] <Skullworks_PGAB> now I need a sub-routine that makes free time
[21:36:06] <Skullworks_PGAB> or even cheap time
[21:37:02] <Skullworks_PGAB> I do have a ubuntu server box to play on though.
[21:37:28] <Skullworks_PGAB> so I'll keep the cgi-bin sys crashes local...
[21:39:21] <anonimasu> alex_joni: that dosent look too insanely hard..
[21:40:00] <anonimasu> :)
[21:45:36] <alex_joni> anonimasu: who said it was?
[21:45:46] <alex_joni> the problem lies in the details :P
[21:45:57] <anonimasu> hehe
[21:46:01] <anonimasu> constraints?
[21:46:07] <alex_joni> small things like joints jumping from -180 to +180
[21:46:16] <alex_joni> which matematically is no difference
[21:46:19] <alex_joni> * alex_joni grins
[21:46:25] <anonimasu> haha
[21:46:53] <alex_joni> and the like..
[21:47:01] <Skullworks_PGAB> inc moves
[21:47:10] <Skullworks_PGAB> not absolute
[21:47:18] <anonimasu> yeah
[22:13:22] <feoc2> w00t
[22:13:30] <feoc2> just won an EDM machine on ebay
[22:13:39] <feoc2> http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=160108710903
[22:16:50] <picnet> there was a space in the workshop?
[22:22:49] <alex_joni> night all
[22:23:27] <picnet> night, machine is up and running ok now.
[22:23:38] <picnet> no following errors :)
[22:25:07] <feoc2> right so what exactly is it an EDM does?
[22:25:10] <feoc2> pmsl
[22:25:31] <anonimasu> holes/parts
[22:25:46] <anonimasu> depends on what kind of EDM
[22:26:13] <feoc2> the one i just got on ebay
[22:26:57] <feoc2> just wanted one to play with
[22:29:23] <anonimasu> damn you
[22:29:24] <anonimasu> I want one ;)
[22:32:07] <feoc2> lol
[22:32:42] <jmkasunich> I wish I could buy a bigger basement on ebay
[22:32:58] <feoc2> i rent a barn from a farmer
[22:33:09] <jmkasunich> barns have no heat
[22:33:18] <jmkasunich> fine for storing non-sensitive stuff
[22:33:33] <jmkasunich> not so good for things that rust, or contain electronics, or both
[22:33:44] <jmkasunich> and not so good for actually working with those things
[22:33:52] <jmkasunich> (unless in a mild climate)
[22:34:03] <feoc2> im fitting it out with a enclosed bit for the machines
[22:34:08] <feoc2> and a spray booth
[22:34:13] <feoc2> so will have heating
[22:34:25] <jmkasunich> that helps
[22:34:45] <jmkasunich> barn with electricity and heat isn't really a barn anymore ;-)
[22:34:58] <picnet> lol
[22:35:21] <feoc2> no i guess not
[22:35:25] <feoc2> but it works for me
[22:35:30] <jmkasunich> good
[22:35:51] <feoc2> next thing on my to buy list is a cnc grinder and an autoclave
[22:35:56] <jmkasunich> (when I think of barn, I think of drafty, with lines of sunlight across the floor from the gaps between the wall boards
[22:36:40] <feoc2> lol
[22:36:44] <feoc2> true
[22:36:52] <feoc2> wasnt too far off that tho
[22:37:08] <feoc2> only better coz im building inside walls
[22:37:25] <jmkasunich> http://www.makeitmacomb.com/historic_barn_tour/barn_photos/1-3-Brock.jpg
[22:37:54] <picnet> no mothers in the basement?
[22:38:21] <feoc2> http://img.photobucket.com/albums/v280/rallyslag/31012007175.jpg
[22:38:27] <feoc2> more like that :)
[22:38:36] <jmkasunich> ah
[22:38:49] <jmkasunich> cee-ment floor even... high class barn!
[22:39:15] <feoc2> :)
[22:40:14] <feoc2> right bed time
[22:40:19] <feoc2> work in mornin
[22:40:23] <jmkasunich> goodnight
[22:40:48] <feoc2> stay up any later and ebay will take all my money
[22:40:53] <jmkasunich> lol
[23:09:32] <Jymmm> jmkasunich: If I got the 300CPR encodes, do you think I could get away wit thme, or show I really go for the 1200+ count ones?
[23:09:46] <jmkasunich> don't ask me
[23:09:51] <Jymmm> damn, my brain cant type anymore
[23:10:03] <jmkasunich> I really think this whole encoder thing is not the way to solve your problems
[23:10:16] <jmkasunich> as for whether 300 cpr will do the job, that is simple math
[23:10:25] <jmkasunich> you have 1600 step/rev steppers
[23:10:39] <jmkasunich> a 300 count per rev encoder will not tell you if you lose 1 or even 3 steps
[23:10:44] <Jymmm> Oh that's right, sorry I was still thinking 200CPR steppers
[23:11:04] <jmkasunich> although...
[23:11:21] <jmkasunich> if you are losing steps in the signal chain between EMC and the drive, you can lose one microstep
[23:11:30] <Jymmm> I'm not using them to "solve" anything, just help determine what the cause of the sisues I'm having are.
[23:11:42] <jmkasunich> if you are losing steps in the motors, you can only lose them in units of four full steps.
[23:12:12] <Jymmm> ok, that makes sense.
[23:12:31] <Skullworks_PGAB> 4?
[23:12:37] <jmkasunich> yeah
[23:12:49] <jmkasunich> a complete cycle of the magnetic field is four full steps
[23:12:59] <Jymmm> microstepping
[23:13:36] <jmkasunich> if you grab the shaft of an energized stepper and force it to turn, it will resist harder and harder, then you will get it "over the hump" and it will snap into a new stable position
[23:13:59] <jmkasunich> on a 200 (full)step/rev motor, that new stable position is 1/50th of a turn away from the original position
[23:15:38] <jmkasunich> max resistance is at one full step away from the stable position, when you get two steps away the resistance goes to zero, when you pass 2 steps it starts pushing toward the next stable position
[23:16:30] <jmkasunich> microstepping breaks the cycle down into finer chunks, the the pattern of the magenetic field doesn't change, its still strongest at 1 full step away from the stable spot
[23:19:30] <Jymmm> I'm reading the gcode page, but I still dont quite get the differnce between G0 and G1
[23:19:56] <jmkasunich> G0 is rapid and goes as fast as it can
[23:20:11] <jmkasunich> G1 is cutting move and moves at a rate set by the last F word
[23:20:41] <Jymmm> si basically G0 "bypasses" any set F words?
[23:20:46] <jmkasunich> yeah
[23:20:52] <Jymmm> any other differences?
[23:21:05] <jmkasunich> I don't think so, but I'm not the expert
[23:21:35] <Jymmm> That's ok, I just wanted to make sur eI understood the differncebecause you mentioned testing using G0 and not G1
[23:21:37] <Skullworks_PGAB> pronounce G ut-oh and G one
[23:21:47] <Jymmm> lol
[23:23:53] <Jymmm> Hey, do you guys know of any websites with the cheap china linear scales?
[23:24:32] <Skullworks_PGAB> one of the importers is on ebay - website not working yet
[23:24:39] <Skullworks_PGAB> Shar tool inc.
[23:24:48] <Skullworks_PGAB> or shars
[23:24:50] <Jymmm> Yeah, I saw one on ebay.
[23:26:18] <Jymmm> http://stores.ebay.com/SMW-Precision-LLC_Linear-Scales-Horizontal_W0QQcolZ2QQdirZ1QQfsubZ4QQftidZ2QQtZkm
[23:26:50] <Skullworks_PGAB> Discount machine is the ebay name for shars
[23:27:40] <Skullworks_PGAB> http://stores.ebay.com/Discount-Machine-Shop_W0QQssPageNameZstrkQ3amefsQ3amesstQQtZkm
[23:28:12] <Skullworks_PGAB> SMW is only a retailer
[23:28:36] <Skullworks_PGAB> I bought there 3 axis glass scale DRO for the IH mill
[23:29:28] <Skullworks_PGAB> package deal :)
[23:31:30] <Jymmm> I wish I could see a detailed pic so I could determine if I could mount it on my machine
[23:31:52] <Skullworks_PGAB> what is the machine?
[23:32:02] <Jymmm> a gantry router
[23:32:29] <Jymmm> http://cgi.ebay.com/24-600mm-HORZ-DIGITAL-ELECTRONIC-DRO-QUILL-BRIDGEPORT_W0QQitemZ260001115191QQihZ016QQcategoryZ12581QQcmdZViewItem
[23:32:47] <Skullworks_PGAB> got some place to machine delrin or lexan?
[23:32:47] <Jymmm> I'm assuming that the LCD is what actually moves
[23:33:04] <Skullworks_PGAB> yes
[23:33:20] <Jymmm> only my router
[23:33:46] <Skullworks_PGAB> but they also have a remote display with AC power so your not going thru batts like crazy
[23:34:05] <Jymmm> does it come with a dat cable though?
[23:34:08] <Jymmm> data
[23:34:24] <Skullworks_PGAB> the dispaly package would
[23:34:42] <Skullworks_PGAB> thats an add on option
[23:35:13] <Jymmm> ah
[23:35:45] <Jymmm> when it says 24" is that literally it 24" or longer than that?
[23:35:53] <Jymmm> 24.5"
[23:36:10] <Skullworks_PGAB> unit is longer - reads 24"
[23:36:30] <Jymmm> k
[23:36:42] <Skullworks_PGAB> you lose some at each end for mounting
[23:36:52] <Jymmm> some of the 24" you mean?
[23:37:01] <Skullworks_PGAB> no
[23:37:13] <Skullworks_PGAB> a 24 reading is like 27"
[23:37:19] <jmkasunich> 26 or so long, you lose 2" for mounting, 24" travel
[23:37:19] <Jymmm> ah, good
[23:38:00] <Jymmm> I'm just not sure if I could mount it on my machine.... pretty tight on the side of the rails
[23:38:56] <Skullworks_PGAB> note: they do not like to move too fast
[23:39:07] <Jymmm> Do the DRO's usually have an data out from them? Like sclaes --> DRO --> computer?
[23:39:12] <Skullworks_PGAB> crazy rapinds... they might error out
[23:39:23] <Jymmm> ok, nm then.
[23:40:00] <Jymmm> I'll see what I can find come monday at Triangle.
[23:40:09] <Jymmm> (a machine surplus store)
[23:40:23] <Skullworks_PGAB> DRO's don't - but wiring up a data spliter is possible I think
[23:40:58] <Jymmm> Ah, well if they dont deal good with rapids, no use even trying.
[23:41:29] <Skullworks_PGAB> how fast can your machin move?
[23:41:37] <Jymmm> 129IPM
[23:41:39] <Jymmm> 120
[23:43:44] <Skullworks_PGAB> http://www.romaxxcnc.com/ watch the jog video - or the engrave vid
[23:47:25] <skunkworks> resolution is going to be pretty low.
[23:48:06] <Jymmm> video or machine resolution?
[23:49:18] <skunkworks> machine
[23:49:52] <Jymmm> ah
[23:50:04] <skunkworks> quote
[23:50:05] <skunkworks> These types of belts have been
[23:50:19] <skunkworks> powering large industrial CNC machine axis's for years with tolerances
[23:50:30] <skunkworks> and repeatability in the ten-thousanths of an inch
[23:50:34] <skunkworks> .010
[23:50:55] <Jymmm> lol
[23:51:01] <skunkworks> and that is 'industrial CNC machine'
[23:54:02] <jmkasunich> the power of marketing... how to lie without lying
[23:54:20] <jmkasunich> yes, tooth belts have been powering industrial CNCs for years
[23:54:39] <jmkasunich> running from one pulley to another, and the second pulley turning a ballscrew!
[23:54:52] <skunkworks> I can't even find what resolution it actually has.
[23:58:58] <skunkworks> I was half expecting them to say something about 10X microstepping gives you ....
