[09:43:18] <alex_joni> http://dsplabs.utt.ro/~juve/blog/index.cgi/photography/01148239064 :)
[09:43:57] <giacus> hehe, cool
[09:44:21] <chinamill> Did you build it yourself?
[09:44:24] <chinamill> :)
[09:44:57] <chinamill> what type of driver do you use?
[09:46:02] <Bo^Dick> alex_joni: i've had a bunny too
[09:48:21] <giacus> alex_joni: did yo use a macro lens for that ?
[09:54:51] <alex_joni> no, the default 18-55
[09:55:02] <Bo^Dick> oooh alex! i want more bunnys
[10:00:07] <Bo^Dick> i love bunnys
[10:04:29] <alex_joni> I eat them
[10:04:31] <alex_joni> ROFLMAO
[10:06:41] <giacus> haha
[10:07:33] <Bo^Dick> alex_joni: who's the person holding the bunnys?
[10:08:13] <alex_joni> my gf
[13:00:00] <cradek> morning everyone
[13:00:17] <alex_joni> hiya chris
[13:00:20] <alex_joni> made it back home?
[13:00:28] <cradek> yep
[13:00:38] <cradek> yesterday evening
[13:00:49] <cradek> now I'm trying to convert back to the schedule of the living
[13:01:03] <alex_joni> hehe.. nic
[13:01:04] <alex_joni> nice
[13:01:57] <cradek> I'm glad I also took today off work
[13:02:43] <Skunkworks> looser
[13:02:52] <Skunkworks> * Skunkworks is at work right now
[13:03:40] <Skunkworks> I was not as hardcore as you guys this weekend
[13:04:06] <cradek> we were at it all week!
[13:05:43] <Skunkworks> you guys got a lot of things work out - great job
[13:06:05] <cradek> yes thanks
[13:06:10] <cradek> it was very productive
[13:14:00] <Skunkworks> did you get the spiral pictures from jepler yet?
[13:14:29] <cradek> no, but I did make it home with the spirals themselves
[13:15:02] <Skunkworks> your not going to get any work done are you. Stop staring at them!
[13:15:05] <Skunkworks> ;)
[13:15:20] <cradek> haha
[13:23:56] <Skunkworks> little dark but :) http://www.electronicsam.com/images/KandT/cncworkshop/cncworkshopemc.JPG
[13:25:55] <jepler> cradek: I just put the eagle .sch and .brd for the l298 on my blog
[13:26:10] <cradek> great
[13:26:12] <cradek> thanks
[13:26:31] <alex_joni> morning jeff
[13:26:34] <jepler> hi alex
[13:26:34] <cradek> Skunkworks: what a handsome bunch of guys, haha
[13:27:34] <jepler> "auto levels" does wonders for the darkness
[13:27:37] <jepler> (in gimp)
[13:27:55] <alex_joni> cradek: care to tell me who's who in that picture?
[13:28:08] <Skunkworks> wait - wait - is gimp a linux program? :)
[13:28:22] <alex_joni> Skunkworks: works on more than one OS
[13:28:24] <jepler> alex_joni: I can tell you
[13:28:35] <alex_joni> jepler: shoot ;)
[13:28:55] <jepler> steve stallings, matt shaver, jmk, me, ray, jon elson, swpadnos, dave-e, not sure, cradek
[13:29:06] <jepler> and it's the mazak in the background
[13:29:21] <cradek> I agree on "not sure"
[13:29:39] <cradek> dave-e's home machine is the same as this one
[13:29:42] <cradek> also run on emc
[13:30:33] <Skunkworks> that is dave-e. I talked to him and never got his name.
[13:30:40] <cradek> jepler: are you at work?
[13:31:31] <cradek> Skunkworks: dave-e is 3rd from right, do you know 2nd from right (next to me)?
[13:31:50] <Skunkworks> right - I got it - so he has a mazak at home running emc?
[13:32:00] <jepler> cradek: not yet, but I am going to go to work
[13:32:22] <jepler> in fact, I should get going
[13:32:37] <jepler> I can't find my compactflash reader, I was going to put up some of my photos of the spiral we made on mazak
[13:32:56] <alex_joni> jepler: thx
[13:33:56] <jepler> cradek: let me know if you run across my CF reader, particularly in the box of stuff where your camera was.
[13:34:08] <cradek> ok
[13:34:26] <cradek> Skunkworks: yes, same machine
[13:35:42] <Skunkworks> has he updated emc yet? with your fixes to the tp.. He seemed very happy with the motion now.
[13:36:17] <cradek> I have not made a new package yet; he uses the packages
[13:36:44] <cradek> I'll do it soon after jmk tests his changes that he was nervous about
[13:38:01] <jepler> crap -- wherever my CF reader is, so is my CF card with the pictures I wanted to show.
[13:38:24] <cradek> I hope it's not lost...
[13:38:26] <jepler> Skunkworks: wasn't that your laptop I had plugged the reader into? did you make it home with my card and reader somehow?
[13:38:34] <cradek> I'll look in the garage pile a little later
[13:38:39] <jepler> well, anyway, off to work.
[13:38:52] <jepler> cradek: the photos aren't important, as long as you still have the real thing.
[13:39:12] <Skunkworks> jepler: no - I would have noticed that.
[13:39:27] <Skunkworks> maybe fenn noticed it
[13:39:28] <cradek> true, but the hardware is worth something too.
[13:39:29] <Skunkworks> ?
[14:13:51] <Skunkworks> do you know if steve talked to jmk about the following error?
[14:17:00] <cradek> I guess I don't know about that, what following error?
[14:18:57] <Skunkworks> steve had mentioned when he tries to turn the machene back on he was getting folloing error
[14:19:13] <Skunkworks> like I did after an estop
[14:19:20] <jepler> which machine?
[14:19:21] <cradek> ah right
[14:19:49] <cradek> jepler: at least stepgen does it, I saw it on ppmc too
[14:20:29] <cradek> you get FE, it turns machine off, when you try to turn machine on, the axis that errored jumps, often erroring again
[14:21:43] <cradek> jepler: does your circuit really require 6 inputs?
[14:22:24] <cradek> I think I'll only have four outputs available since I have to use parport input mode
[14:23:05] <jepler> cradek: my understanding is that you can get by with chopping on INPUT[1..4] and not using ENABLE_x
[14:23:09] <jepler> but I haven't tried it
[14:23:16] <cradek> ok
[14:23:28] <cradek> I may be able to just barely get by with one port then
[14:23:43] <jepler> I haven't tried it but obviously you can with my board
[14:24:02] <cradek> although if I use a pc with slots I can easily get two ports in it
[15:08:06] <dmessier> well it appears my laptop wont boot from usb device ; (
[15:11:31] <A-L-P-H-A> whusabi
[15:22:49] <Skunkworks> logger_aj:bookmark\
[15:22:49] <Skunkworks> See http://81.196.65.201/irc/irc.freenode.net:6667/emc/2006-05-22#T15-22-49
[15:24:37] <Skunkworks> charter went down for a bit :(
[15:35:48] <A-L-P-H-A> damn msn
[15:35:54] <A-L-P-H-A> anyone having connection issues with msn?
[15:36:48] <Skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop/fennalum.JPG
[15:37:41] <Skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop/fennpour.JPG
[15:38:23] <bill203> any pics of the results?
[15:38:37] <cradek> Skunkworks: I'm anxious to see the rest of your photos
[15:39:24] <Bo^Dick> Skunkworks: so you do castings
[15:39:58] <jepler> http://superpositioned.com/articles/2006/05/17/are-you-logical-digital-logic-puzzlers
[15:40:17] <jepler> * jepler is still stuck on the no-XOR version of the above puzzle
[15:40:33] <Skunkworks> I was hoping someone had results of fenns casting - it turned out pretty good. We forgot to take one.
[15:41:08] <Skunkworks> Bo^Dick: this was from the cnc workshop and cardinal engineering
[15:41:42] <Skunkworks> I will get them all up when I get a chance.
[15:45:50] <Skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop/cradeksthread.JPG
[15:46:30] <jepler> nice photo
[15:46:32] <cradek> cool
[15:47:02] <cradek> that's a fast snap, you must have had a flash
[15:47:12] <A-L-P-H-A> stupid msn...
[15:47:37] <A-L-P-H-A> how's the thread being cut? CNC threading? single point I see.
[15:48:06] <jepler> A-L-P-H-A: emc2's new g33 spindle-synchronized move
[15:48:24] <jepler> the lathe has a 1024-line encoder on the spindle
[15:48:26] <A-L-P-H-A> oh neat... goodie... turbocnc has had that for a long time.
[15:48:45] <A-L-P-H-A> my machine can't move that fast anyways... I need to rewire them to be in series...
[15:49:30] <jepler> rewire the stepper motors?
[15:49:45] <A-L-P-H-A> yeah... my speeds are too slow to do anything useful like threading.
[15:50:09] <A-L-P-H-A> frack... do I want to do that today?
[15:50:10] <A-L-P-H-A> :/
[15:50:39] <cradek> A-L-P-H-A: your spindle won't go slow enough?
[15:50:55] <A-L-P-H-A> it will, but then the torque is all gone.
[15:51:04] <A-L-P-H-A> I've got a rheostat on the DC servo.
[15:51:10] <A-L-P-H-A> as my spindle drive.
[15:51:20] <A-L-P-H-A> with a single pulse encoder.
[15:51:41] <cradek> hmm, sounds like it'll need some work before you can do threads well
[15:51:52] <A-L-P-H-A> cradek... I always have dies. ;)
[15:52:04] <A-L-P-H-A> I've got a tail stock, and dies...
[15:52:14] <A-L-P-H-A> would be nice if I could rough it out though first. :/
[15:52:17] <cradek> yeah often that's good enough
[15:52:34] <cradek> until you need to find metric left-hand dies or something
[15:53:42] <A-L-P-H-A> true
[15:54:30] <Skunkworks> A-L-P-H-A: is this what we where talking about the other day? You have 150k pulses per inch about?
[15:54:37] <Skunkworks> that was the main problem.
[15:54:58] <A-L-P-H-A> I have too little pulses for my setup
[15:56:10] <dmessier> he'd need about 150l if i recall
[15:56:19] <dmessier> 150
[15:56:26] <dmessier> k
[15:56:32] <A-L-P-H-A> I need a G100/101 from geckodrive.
[15:58:33] <jepler> why so many steps per inch?
[15:58:48] <A-L-P-H-A> microsteps... 1/10 from gecko G201
[15:58:59] <A-L-P-H-A> my TPI is 5tpi ball screws.
[15:59:18] <A-L-P-H-A> geared down to 3:2 or somethng like that... I remember the number being 1:1.6 for some reason
[15:59:47] <jepler> you can't select fewer microsteps on the gecko?
[16:00:10] <A-L-P-H-A> no.
[16:00:21] <A-L-P-H-A> I'd have to buy the pulse multiplier... ~40USD each
[16:00:35] <Skunkworks> mazaks first chips with emc http://www.electronicsam.com/images/KandT/cncworkshop/mazaksfirstchips.JPG
[16:02:02] <A-L-P-H-A> make the ball in the cube frame thing... cause it's cool
[16:03:22] <Skunkworks> the spirals cradek milled where cool. jepler programed them - one with strait line segments and one with arcs
[16:03:46] <Skunkworks> jepler got some really cool photos of them.
[16:03:55] <jepler> Skunkworks: yeah if only I had the card they were on
[16:04:14] <Skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop/mazakpart.JPG
[16:04:18] <jepler> If not I'll take some more
[16:04:20] <Skunkworks> your missing the card too?
[16:04:30] <jepler> Skunkworks: yes, I'm sure the card is in the reader .. wherever it is
[16:04:37] <Skunkworks> shoot.
[16:04:52] <Skunkworks> where is fenn - maybe he saw it.
[16:06:33] <A-L-P-H-A> what spirals?
[16:07:05] <jepler> http://cvs.linuxcnc.org/cvs/emc2/nc_files/spiral.ngc?rev=1.3 http://cvs.linuxcnc.org/cvs/emc2/nc_files/arcspiral.ngc?rev=1.2
[16:07:09] <jepler> these ngc files
[16:07:16] <jepler> you can view them in axis if you have it installed
[16:08:25] <A-L-P-H-A> I wanna see the spirals... the finished product.
[16:08:26] <A-L-P-H-A> :)
[16:08:36] <jepler> it's a test for the interpreter and motion planner: each arc or segment covers a fixed angle, so they become shorter and shorter towards the center
[16:09:29] <jepler> with the mazak you can actually see each cut of the tool's tooth, and you can see that they are uniformly spaced over the entire piece -> the trajectory planner gave good results
[16:09:36] <jepler> by meeting the requested feed rate at all times
[16:09:48] <jepler> I really wish I had the photos
[16:10:17] <A-L-P-H-A> I would really have liked to have seen that.
[16:23:59] <dmessier> congrats... the spiral test is a good one.. ; )
[16:24:19] <alex_joni> http://www.pro-linux.de/news/2006/9690.html
[16:26:18] <A-L-P-H-A> I don't read german... :( and I'm sure as heck not gonna ask my exGF to translate it
[16:28:07] <cradek> as far as I can tell, EMC2 can control robots, hexapods, and a few other Nouns
[16:28:36] <cradek> with a variety of interface hardware
[16:28:37] <A-L-P-H-A> I would be rude, and mention some fetish sex sites... but I think people can use their imaginations enough.
[16:28:54] <cradek> eh?
[16:29:12] <cradek> alex_joni: what is pro-linux.de?
[16:30:09] <jepler> it's about the release of emc2
[16:30:13] <jepler> it lists some of the features
[16:30:13] <A-L-P-H-A> probably a linux fanboy site.
[16:30:18] <jepler> some of the hardware it works with
[16:30:49] <cradek> it looks like a nice summary for not being written by any of us
[16:31:46] <alex_joni> cradek: indeed it does
[16:31:52] <A-L-P-H-A> off to the gym.
[16:32:35] <Lerneaen_Hydra> what was so special about the image skunkworks linked to?
[16:32:52] <cradek> which one?
[16:32:54] <jepler> Lerneaen_Hydra: it's the first things machined on the mazak
[16:33:03] <jepler> Lerneaen_Hydra: which ray and jmk (and others) have just finished retrofitting with emc2
[16:33:04] <Lerneaen_Hydra> http://www.electronicsam.com/images/KandT/cncworkshop/mazakpart.JPG
[16:33:14] <Lerneaen_Hydra> the mazak?
[16:33:22] <Lerneaen_Hydra> some new/fast/good mill?
[16:33:49] <jepler> It's an old machine. Some information on last year's work is here: http://fenn.freeshell.org/retrofest/default.html
[16:33:52] <cradek> that's the first part cut on the machine undergoing an emc conversion
[16:34:19] <Lerneaen_Hydra> ah, ok. was the conversion done during fest?
[16:34:30] <alex_joni> Lerneaen_Hydra: last year mostly
[16:34:30] <cradek> yes, starting at last year's
[16:34:54] <A-L-P-H-A> is it still going on?
[16:35:05] <A-L-P-H-A> or is it over, and swpadnos should be on his way home?
[16:35:12] <Lerneaen_Hydra> that machine (mazak) seems to be very... large
[16:36:04] <cradek> it sure is
[16:36:17] <Lerneaen_Hydra> now that I look at those images, that mechanical base seems very, very famliliar
[16:36:36] <Lerneaen_Hydra> let me find an image to compare with one at my school I've used quite a lot
[16:43:56] <Lerneaen_Hydra> ftp://basic:[email protected]
[16:44:03] <Lerneaen_Hydra> file called: modig md7000.avi
[16:49:49] <jepler> can't connect
[16:50:24] <Lerneaen_Hydra> oh, looks like dyndns didn't update
[16:50:41] <Lerneaen_Hydra> ftp://basic:[email protected]
[16:54:46] <jepler> that toolchanger looks really familiar, a lot like the one on this mazak
[16:55:28] <Skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop/spiralarc.JPG
[16:55:36] <Skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop/spiralline.JPG
[16:55:52] <Skunkworks> not too bad - jeplers where cooler :)
[16:55:54] <bill203> pretty
[16:56:23] <Lerneaen_Hydra> jepler: the machine is a Modig MD7000
[16:56:39] <Lerneaen_Hydra> running with a heidenhein tnc 415 system
[16:57:06] <dmessier> yuck
[16:58:24] <Lerneaen_Hydra> yes, it's rather primitive
[16:58:54] <Lerneaen_Hydra> however streaming programs off an external computer works well so when using CAM systems it works very well
[17:03:22] <dmessier> yes the eternet link is nice
[17:03:27] <dmessier> ethernet
[17:05:52] <Lerneaen_Hydra> hmm, that one doesn't have ethernet, it's a com/parport link of some kind
[17:12:20] <NickServ> This nickname is owned by someone else
[17:12:20] <NickServ> If this is your nickname, type /msg NickServ IDENTIFY <password>
[17:13:26] <cradek> hi steve
[17:14:09] <steve_stallings> hi chris, just got in from my return trip and noticed my IRC connection had dropped
[17:17:07] <Lerneaen_Hydra> looks like many people dropped from IRC, looks like 9 people or so
[17:39:02] <davef> Hi..
[17:42:07] <davef> I was hoping to ask Bo_Dick about the waveform pics he posted yesterday.
[17:42:22] <davef> But I see he's not here...
[17:42:41] <steve_stallings> steve_stallings is now known as steves_logging
[17:57:49] <fenn_> fenn_ is now known as fenn
[17:58:12] <Skunkworks> Hey fenn.
[18:00:25] <dmess>
[18:02:08] <Skunkworks>
[18:03:15] <alex_joni>
[18:05:04] <Lerneaen_Hydra> uh, is it just me or did dmess, Skunkworks, and alex_joni just write emtpy lines of text?
[18:05:08] <jepler> Skunkworks: those photos aren't bad .. the spiral one shows the slight "X" backlash clearly, for instance.
[18:05:20] <jepler> Lerneaen_Hydra: those lines look blank to me too
[18:05:43] <alex_joni> Lerneaen_Hydra: it's a new game :D
[18:05:46] <Skunkworks> I was just following dmess's leak :)
[18:05:51] <Skunkworks> lead I mean
[18:05:52] <alex_joni> communicate without saying anything
[18:05:53] <Lerneaen_Hydra> ah, ok
[18:06:41] <Lerneaen_Hydra> like john cage?
[18:07:22] <alex_joni> Lerneaen_Hydra: who?
[18:07:36] <Skunkworks> jepler: thanks - father loves taking pictures :)
[18:07:49] <Lerneaen_Hydra> the musician that had a music track that was 4:33 of silence
[18:07:59] <alex_joni> Lerneaen_Hydra: oh.. missed that one
[18:20:05] <chinamill_> chinamill_ is now known as chinamill
[18:25:08] <A-L-P-H-A> damn the gym feels good
[18:26:10] <alex_joni> A-L-P-H-A: IRC from the gym?
[18:26:15] <A-L-P-H-A> nono.
[18:26:17] <A-L-P-H-A> got back.
[18:26:21] <alex_joni> that quick???
[18:26:22] <A-L-P-H-A> gym, washed the car, back
[18:26:23] <alex_joni> :D
[18:26:34] <alex_joni> that was .. like .. 2 minutes?
[18:26:38] <alex_joni> :-)
[18:26:42] <A-L-P-H-A> I left at 12:30, it's now 2:30.
[18:26:50] <A-L-P-H-A> I was at the gym for maybe an 1.5hrs.
[18:26:52] <alex_joni> felt like 2 minutes
[18:27:01] <A-L-P-H-A> and I think it's soon to replace the bats in my wireless kb/mouse
[18:27:18] <A-L-P-H-A> aj... thanks. :P
[18:27:37] <A-L-P-H-A> alex_joni, so when you getting a mill or lathe? ;)
[18:27:55] <alex_joni> A-L-P-H-A: no time soon, probably :D
[18:28:21] <A-L-P-H-A> alex_joni, do you play with EMC strictly for robots?
[18:28:38] <alex_joni> I have 2 sherline slides
[18:28:44] <alex_joni> but I play mostly for fun :D
[18:28:58] <A-L-P-H-A> no, that's cool... seems like something I would have done a few years back.
[18:29:21] <A-L-P-H-A> my tricepts are going to feel it sooo bad tomorrow... or maybe even the day after. :(
[18:29:35] <A-L-P-H-A> had problems already lifting the damn power washer... heh.

[19:02:22] <Skunkworks> jepler and I
[19:02:55] <Skunkworks> cradek and jmk are facing away (working on the mazak emc computer.
[19:18:53] <alex_joni> Skunkworks: nice fotos
[19:19:46] <Skunkworks> father took them all.
[19:33:04] <davef> http://www.ecircuitcenter.com/Circuits/curr_src1/curr_src1.htm
[19:33:18] <alex_joni> Skunkworks: he's quite good at it :)
[19:33:51] <K4ts> hello
[19:35:06] <alex_joni> hi
[19:35:18] <davef> The link above is the general idea for constant current output using an op amp & BJT.
[19:36:50] <davef> (re Bo-Dick asking for low cost driver ckt yesterday.) Never tried this with a stepper, but it should work I think, with some spike protection, etc.
[19:37:21] <alex_joni> davef: he should just buy them drives and get on with it
[19:37:30] <davef> Agree.
[19:38:39] <alex_joni> then again.. let him have his fun :D
[19:39:08] <A-L-P-H-A> they should really add an anti-foaming agent into protein shakes...
[19:39:29] <alex_joni> at one point he was trying to replicate a L297/L298 drive
[19:40:22] <davef> Thats pretty straight forward, but no chopper as I recall.
[19:41:07] <davef> There's a lot to be said for the knowledge gained (& fun) of DIY.
[19:41:10] <Skunkworks> I should talk - trying to make a pwm power stage ;)
[19:41:39] <Skunkworks> but atleast I am not trying to make the ir2111 ;)
[19:41:54] <alex_joni> I made my own DC PWM drives, I'll never do that again
[19:42:13] <alex_joni> Skunkworks: I'll kick you if you say the i* word again
[19:42:18] <alex_joni> ;-)
[19:42:31] <davef> I'm impressed!
[19:42:43] <alex_joni> davef: of what?
[19:42:50] <A-L-P-H-A> I've done the AVR (asm for atmels) on a DC PWM speed controller...
[19:42:58] <A-L-P-H-A> with lotsa help from swpadnos.
[19:43:10] <davef> More impressed.
[19:43:10] <A-L-P-H-A> on=for
[19:43:58] <anonimasu> hello
[19:44:08] <A-L-P-H-A> OH YEAH! anonimasu too helped out.
[19:44:11] <A-L-P-H-A> sorry. ;)
[19:44:27] <davef> BTW, what's ir2111? (oops I mentioned it.) :)
[19:44:33] <alex_joni> davef: here's my 'toy' http://dsplabs.utt.ro/~juve/yanor/
[19:44:47] <Skunkworks> it is a half bridge driver for hexfets
[19:44:52] <alex_joni> davef: a chip which generates negative voltages to drive the lower side of a bridge using mosfets
[19:45:29] <davef> I see.
[19:45:48] <A-L-P-H-A> http://www.googleityoumoron.com/?go=ir2111
[19:45:55] <alex_joni> A-L-P-H-A: LOL
[19:46:07] <Skunkworks> to do something like this http://www.electronicsam.com/images/KandT/eaglesch.JPG
[19:46:41] <Skunkworks> (ic1 and 2)
[19:47:35] <jepler> Is it a negative voltage that is generated? I thought it was a voltage higher than Vdrive.
[19:48:44] <alex_joni> jepler: errr. what you said
[19:48:49] <fenn> jepler: i havent seen your card/reader anywhere
[19:48:52] <davef> alex_joni: Holy Cow. I'll take a good look later. Cool! :)
[19:49:00] <alex_joni> some strange voltage either way
[19:49:01] <jepler> fenn: drat. I'm waiting for cradek to look through his stuff.
[19:49:05] <jepler> fenn: thanks for looking
[19:49:10] <A-L-P-H-A> WOW... it's been a while since I've been awake at 3pm.
[19:49:21] <fenn> seems i left some stuff there too
[19:49:26] <fenn> oh well
[19:49:31] <jepler> it was bound to happen
[19:49:41] <alex_joni> you'll get it next year :D
[19:50:08] <cradek> jepler: I haven't unpacked everything yet, but I don't see it on top anywhere
[19:50:27] <davef> A-L-P-H-A: uh, thanks. I'll try that. ;)
[19:50:52] <alex_joni> davef: he's kidding.. don't take us too serious
[19:51:04] <davef> :)
[19:51:08] <davef> np.
[19:51:14] <A-L-P-H-A> the link does work! :)
[19:52:03] <A-L-P-H-A> no wonder I was cold... it's 11oC outside.
[19:59:00] <dmessier> i hear ya.. any one know why MESHCAM is on the bdi4.20 and it apperars to be a windows application?
[19:59:19] <A-L-P-H-A> dmessier? the use of wine? who knows... BDI was sooo messed.
[19:59:31] <A-L-P-H-A> at least it wasn't easy / fun for me.
[19:59:54] <alex_joni> A-L-P-H-A: we had 32 today.. deg.C I mean
[20:00:02] <Skunkworks> ubuntu for the win ;)
[20:00:09] <dmessier> i had few issues with it... once i fugered it had to be installed sober...
[20:00:21] <alex_joni> dmessier: lol
[20:00:30] <alex_joni> you did? wonder how you figured that out..
[20:00:56] <Skunkworks> I had a hard time sober
[20:01:00] <dmessier> i still have a box wit a stray GRUB hangin around..
[20:01:15] <alex_joni> fdisk /mbr
[20:01:22] <dmessier> yup...
[20:02:09] <dmessier> but it scares my son when it boots to it... he feels like he's coming to tell me its got a virus.. LOL
[20:02:51] <alex_joni> he's scared of linux?
[20:03:17] <A-L-P-H-A> 32?
[20:03:23] <A-L-P-H-A> I'll meet you halfway?
[20:03:37] <A-L-P-H-A> 21.5oC that'd be awesome.
[20:03:43] <dmessier> livin in the basement...
[20:04:08] <dmessier> he doesnt like BLACK SCREENS
[20:04:16] <alex_joni> BLUE?
[20:04:26] <A-L-P-H-A> WTF... he doesn't like BLACKSCREENS... how racist... just give him BSOD.
[20:04:47] <A-L-P-H-A> BSOD = blue screen of death
[20:04:58] <Skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop/mazake1.JPG
[20:05:04] <Skunkworks> http://www.electronicsam.com/images/KandT/cncworkshop/mazake2.JPG
[20:05:16] <A-L-P-H-A> XP is soo much better... it doesn't give a BSOD... just locks up, dies, reboots, or completely freezes.
[20:05:18] <dmessier> he doesnt fare well with those either
[20:05:25] <Skunkworks> mazak electronics now - minus the drives (mounted in a differnt location)
[20:05:27] <A-L-P-H-A> dmessier, how old is he?
[20:05:38] <alex_joni> A-L-P-H-A: NOT true.. just had a BSOD today :)
[20:05:45] <A-L-P-H-A> I do'nt get them...
[20:05:48] <A-L-P-H-A> my computer just locks up.
[20:05:53] <alex_joni> seems XP didn't like me disabling the wireless interface..
[20:05:58] <dmessier> i have a 15 and 13 yr old
[20:05:58] <A-L-P-H-A> but only when Ihave my bluetooth dongle plugged into a usb port
[20:06:01] <alex_joni> I never had one before :)
[20:06:13] <dmessier> sons.. and 11 yr old daughter
[20:06:18] <A-L-P-H-A> i don't know why... doesn't happen on my laptop with the dongle.
[20:06:37] <A-L-P-H-A> wow, they're 2years apart each...
[20:06:41] <A-L-P-H-A> that would mean...
[20:07:05] <dmessier> will the blue tooth dongle work in linux??
[20:07:19] <alex_joni> dmessier: sure.. just that it won't be blue
[20:07:20] <alex_joni> :D
[20:07:23] <dmessier> i got laied every 2 yrs... yup
[20:07:54] <A-L-P-H-A> for ($i = 1; $i <= 3; i++) {get_preg(); wait(rand(months));};
[20:07:54] <alex_joni> Skunkworks: not really working right now..
[20:08:00] <A-L-P-H-A> dmessier, yup. it will.
[20:08:13] <Skunkworks> I see that - my site seems to be chunking.
[20:08:31] <Skunkworks> too many people looking at pictures ;)
[20:08:43] <A-L-P-H-A> oh shit... it wouldn't compile if I tried... I was missing a "$" in front of i++
[20:09:03] <alex_joni> no $ in C
[20:09:05] <A-L-P-H-A> Skunkworks... heard of flickr?
[20:09:09] <A-L-P-H-A> alex_joni, that was php.
[20:09:13] <A-L-P-H-A> haven't touched C in years.
[20:09:14] <dmessier> will it find my phone..??
[20:09:22] <alex_joni> thought you never compile php??
[20:09:26] <alex_joni> :-P
[20:09:27] <A-L-P-H-A> dmessier, tried calling your phone?
[20:09:41] <bill203> it still compiles.
[20:09:46] <A-L-P-H-A> alex_joni, you can... you could make them runtime binaries... but it's a major pain in the ass.
[20:09:53] <dmessier> how??
[20:09:54] <bill203> it just doesn't tell you about it.
[20:10:03] <A-L-P-H-A> dmessier. pick up the phone, and call.
[20:10:12] <A-L-P-H-A> dmessier. use skypeOut... it's FREE.
[20:10:49] <A-L-P-H-A> alex_joni, normally speaking, you're right... php is interpretted.
[20:11:09] <dmessier> no my cell has blue tooth if om within 6 M it says new drive found... for msgs/ pics/music
[20:11:16] <alex_joni> A-L-P-H-A: just pulling your leg.. if you want to compile it.. be my guest
[20:11:26] <alex_joni> you can even write a compiler for it :D
[20:11:46] <A-L-P-H-A> dmessier? how how what? getting BT to work on linux?
[20:12:15] <A-L-P-H-A> you'll need to get the proper kernel modules and crap... I just know mine's compatible, as I looked it up first before I went and bought it.
[20:14:12] <Skunkworks> alex_joni: seems to be working now.
[20:14:31] <A-L-P-H-A> Skunkworks, use flickr... :)
[20:14:42] <alex_joni> Skunkworks: yup
[20:14:49] <dmessier> hmm ok
[20:14:50] <Skunkworks> yah - I have not been known for my website design ;)
[20:15:19] <A-L-P-H-A> how's the HD held in place?
[20:15:24] <A-L-P-H-A> the ziptie only?
[20:15:26] <Skunkworks> it is mainly a place to store files/pictures I link to.
[20:15:37] <Skunkworks> A-L-P-H-A - yes :)
[20:16:39] <Skunkworks> No - I think the wire tie holds the ribbon
[20:17:43] <alex_joni> A-L-P-H-A: one long screw going right through the middle
[20:17:55] <alex_joni> you need to be carefull not to stop the disks though
[20:18:05] <Skunkworks> I would have used epoxy
[20:18:56] <Skunkworks> looks like they are using parrallel port for io also.
[20:19:26] <alex_joni> btw.. did you see this? http://www.grandideastudio.com/portfolio/index.php?id=1&prod=20
[20:20:03] <A-L-P-H-A> ugly... but interesting.
[20:20:08] <alex_joni> ugly??
[20:20:20] <A-L-P-H-A> the HD table.
[20:20:24] <Skunkworks> does it spin at 9k rpm though?
[20:21:07] <A-L-P-H-A> yes... I would have liked it nice shiny silver or black... or woodgrain. not iron/copper colored... but that's me.
[20:22:11] <alex_joni> 15rps = 900 rpm
[20:22:22] <alex_joni> and it was about 2.5 MB big
[20:22:24] <anonimasu> t
[20:22:29] <alex_joni> * alex_joni read the manual :))
[20:25:04] <alex_joni> g'night all
[20:25:33] <anonimasu> rnight
[20:48:36] <DaveF> A-L-P-H-A: re BSOD - seen this? :)
[20:49:23] <DaveF> Retirement party for IBM exec that invented ctrl-alt-del
[20:49:58] <DaveF> http://www.devilducky.com/media/28888/
[20:52:16] <fenn> yep i bet the amputees love him
[20:52:43] <DaveF> LOL
[20:53:52] <DaveF> I've seen an article about the speech but I think the video is hysterical.
[21:02:30] <robin_sz> meep?
[21:05:02] <fenn> * fenn kicks sourceforge and watches it twitch
[21:10:55] <Skunkworks> I hear some of the source forge prjects are down again ;)
[21:12:23] <Skunkworks> hey fenn - did you get any pictures of your lost foam castings?
[21:12:32] <Skunkworks> We forgot to.
[21:32:13] <fenn> Skunkworks: no but about 90 other people did, so i hope they will post them
[21:32:29] <fenn> i left all the casting stuff there on accident so looks like i wont be able to take any pictures either :)
[21:34:06] <Skunkworks> darn. :)
[21:34:57] <fenn> guess i wont be getting that tailstock done any time soon
[21:35:30] <Skunkworks> bbl
[21:36:54] <dmess> nice to see CHIPS fellas... ; )
[22:06:07] <K4ts> night
[22:06:12] <K4ts> night
[22:16:40] <DaveF> A-L-P-H-A: You there?
[22:21:18] <DaveF> I think I was wrong about what I said re series connection. Very sorry if I caused you more work. But, series has higher inductance at relatively low speeds & can increase performance. Looking at some torque vs RPM curves it looks like // definitely has better torque at higher RPM. I feel bad if I caused you needless work.
[22:22:23] <DaveF> http://www.ams2000.com/stepping101.html
[22:22:53] <DaveF> series vs // paragraph near4 bottom of that page.
[22:23:24] <DaveF> http://www.kelinginc.net/23H.pdf
[22:24:12] <DaveF> Torque vs speed curves for my motors.
[22:25:36] <DaveF> I apologize for speaking before I double checked. Had it bassakwards it seems.
[22:27:54] <robin_sz> series has higher inductance ...
[22:28:21] <DaveF> But, an engineer at Parker Compumotor told me that low impedance can cause big problems, and since series gives higher impedance, it might be worth a try.
[22:28:29] <robin_sz> so .. if you drive is short on current, but good on volts, try series, if the drive has plenty of current, user parallel
[22:28:43] <robin_sz> low impedance can cause problems .. with crappy drives
[22:29:17] <robin_sz> modern, FET based drives at 20KHz, have no problem with very low inductance
[22:29:19] <DaveF> Makes sense.
[22:30:08] <DaveF> * DaveF tries to remove foot from mouth
[22:31:13] <robin_sz> in general, you'll do better with parallel, on a good modern drive
[22:31:40] <robin_sz> * robin_sz is still laughing at who won Eurovision :)
[22:36:55] <DaveF> Saw them on the tube yesterday - sitting around the pool sipping cocktails in full garb. Pretty funny. :)
[22:38:25] <robin_sz> yeah, quite a crew
[22:38:54] <robin_sz> look like KISS, sound like Alice Cooper
[22:40:24] <DaveF> Look like Kiss on steriods X Vulcan.
[22:41:04] <robin_sz> hmm, maybe not KISS, maybe Iron Maiden is closer
[22:41:04] <robin_sz> whatever, given Eurovision a kick up the arse for sure
[22:41:12] <robin_sz> yeah
[22:41:16] <robin_sz> yeugh ... htose are your motors?
[22:41:39] <robin_sz> not exactly unstoppable are they?
[22:44:27] <DaveF> There are several on that page. Mine are the 282 oz. in. On a Taig Micro Mill.
[22:44:39] <DaveF> 282 on x,y 425 on Z.
[22:44:46] <robin_sz> 282, thats what, 1.2Nm?
[22:45:48] <DaveF> S/B plenty. Stock motors for the mill are 200 oz in, so I figured that was enough. Haven't connected them yet. Just got them in.
[22:46:09] <DaveF> Sounds right. I'll check...
[22:50:31] <DaveF> 282 oz in = 1.974 Nm
[22:50:43] <DaveF> 425 oz in = 2.975 Nm
[23:36:48] <robin_sz> 3Nm then
[23:37:01] <robin_sz> sounds OK for a small mill
[23:37:20] <robin_sz> gear for about 2mm per rev I would say
[23:43:17] <DaveF> Hmm... I haven't thought too much about it yet. I just know the factory gets 30 in per min with 200 oz in, so I guessed Id get 45 or so.
[23:43:52] <DaveF> Lead screws are 20 TPI, motor mount is direct drive.
[23:45:38] <DaveF> 20 TPI = 1.27 mm/rev
[23:47:14] <DaveF> * 800 RPM (hope I can get that at least) = 40 ipm rapids
[23:48:20] <fenn> sounds usable
[23:48:33] <giacus> hi
[23:48:52] <DaveF> hi gacus
[23:49:41] <giacus> hi DaveF , how proceed the work ? :)
[23:50:12] <DaveF> Work? uhh.. oh, yeah...
[23:50:22] <DaveF> :)
[23:51:48] <DaveF> Just got ubuntu live cd downloaded with a good checksum finally. Haven't burned it yet. That's as far as I've gotten. Had some distractions.
[23:52:25] <DaveF> I left a post for ALPHA above. hope I didn't mess him up.
[23:52:32] <fenn> if you have problems downloading large files like .iso's you should use bittorrent, as it checks each piece as it downloads
[23:53:51] <DaveF> great! I'll try that next time. I got some bad sectors on my C drive. They are covered up right now by a bad checksum EMC download, so I'm ok till I delete it LOL.
[23:54:39] <giacus> DaveF: what FS ?
[23:54:44] <DaveF> But the drive is almost full, so every time I delete something big, I'm back to bad bytes. :(
[23:55:46] <DaveF> giacus: FS?
[23:55:52] <giacus> file system
[23:55:59] <DaveF> win 98
[23:56:10] <DaveF> I'm a dinosaur.
[23:56:13] <giacus> fat32 ?
[23:56:15] <giacus> haha
[23:56:20] <DaveF> think so yes
[23:56:40] <DaveF> got a suggestion?
[23:57:05] <giacus> I always used ext3 until now
[23:57:20] <giacus> but reiserfs should be nice for some
[23:57:42] <giacus> wonder some tool you could try to use ..
[23:57:57] <giacus> I never had issues with my FS :(
[23:57:59] <giacus> :D
[23:58:52] <giacus> the live cd could have some tool to repair sector
[23:59:15] <DaveF> Well, all I know about that is that when windows somehow mysteriously SOMETIMES finds bad sectors, It starts scandisk at bootup and marks them as bad. But I can't figure out how to force a check & fix at will.
[23:59:21] <giacus> fscheck maybe
