[00:11:57] <MacGalempsy> andypugh: finally got the cards all pined up, now just trying to figure out programming the mesa card
[00:12:09] -!- thomaslindstr_m has quit [Quit: Leaving...]
[00:12:23] <andypugh> How much programming does it need?
[00:13:09] -!- Tom_L has quit [Client Quit]
[00:13:15] <MacGalempsy> well pinning out has thrown me for a loop
[00:14:39] <MacGalempsy> PNC Config is not so straight forward, so i just printed out the walkthrough and about to read it
[00:16:59] -!- geografa has quit [Quit: Computer has gone to sleep.]
[00:17:29] <andypugh> The only tricky bit is working out which firmware option suits you. Unless you are using a 5i25, in which case it should have the firmare you asked for already there.
[00:17:52] <Tom_itx> thanks andypugh

[00:22:30] <MacGalempsy> andypugh: I can see all the pins for the 7i77 and 7i84, but there is no firmware for the combo. so jthornton mentioned to do an initial setup with the 5i25 and the 7i77x1, then come back and edit the HAL file for the 7i84
[00:23:16] <andypugh> <confused>
[00:23:45] <MacGalempsy> yeah, totally me too
[00:23:58] <andypugh> Ah, 7i84 is smart-srial?
[00:24:02] <MacGalempsy> yes
[00:24:18] <andypugh> So, the 7i77 firmware is the correct one.
[00:24:43] <andypugh> do you mean that there isn't an XML file for the combo?
[00:24:50] <MacGalempsy> yes
[00:25:59] <andypugh> Yeah, so ignore the 7i84 initially, create a 7i77-only config, then do a pin-list to see what pins the 7i84 has, and add those to the HAL file manually.
[00:27:17] <MacGalempsy> ok. getting checked in with work, then will migrate out to the garage. will likely have more questions in about an hour

[00:45:44] <andypugh> The Mac version of FreeCAD doesn't do anything at all. It launches, but opens no windows and does nothing.

[00:50:47] <PetefromTn> LOL that sucks....
[00:51:33] <andypugh> Soeone on their forum has an alternative build, I am trying that
[00:53:47] <PetefromTn> Lots of folks compile their own from the sourceforge website but I don't even know what that means LOL.
[00:58:55] <andypugh> And it works!
[00:59:33] <andypugh> It's an ugly programme, though, and the mouse zoom is about 100x too sensitive. One wrong touch and the model shrinks to 1 pixel.
[01:00:07] -!- patrickarlt has quit [Remote host closed the connection]
[01:00:10] <andypugh> Time for me to be asleep.
[01:00:13] <PetefromTn> Really? I did not see that..
[01:00:33] <PetefromTn> Maybe you can adjust the settings and there are several different mouse settings in there too
[01:00:45] <andypugh> This is the Mac version, with the touch-sensitive swipey mouse.

[01:05:07] <PetefromTn> There are some different arrangements for using it with the thumbwheel, left and right mouse buttons etc.
[01:05:18] <andypugh> It turns out it was only 20x too fast, I exagerated :-)

[01:09:01] <PetefromTn> cool. See what you think. You are good with this stuff maybe you can figure out how to make it work better. I am no programmer and I wish the program would work without crashing it actually is pretty easy to use.
[01:10:08] <PetefromTn> Gotta go to the store be back in a bit. Nite Andy. Peace

[01:10:12] <andypugh> To be honest, as I have a free Autodesk Inventor license, and I know how to use that (I was a CAD jockey for a couple of years, using inventor) I can't really see myself spending all that much time with FreeCAD
[01:10:37] <PetefromTn> Well that sucks.... I understand tho.

[07:43:13] <_DJ_> moin
[07:44:34] <cpresser> Jymmm: i tried. for tabletop minatures
[07:44:50] <cpresser> but i failed. i could reproduce enough details
[07:45:17] <Jymmm> cpresser: Bummer, that's EXACTLY what I need in this cae
[07:45:18] <Jymmm> case
[07:46:44] <cpresser> Jymmm: this was another try: http://imagebin.org/276023
[07:46:45] <archivist> you are doing it wrong then, we had an external foundry do copies for us and the detail was good
[07:47:20] <Loetmichel> Jymmm: i made some tin molds out of 2k high temperature silicvcone
[07:47:27] <cpresser> my approach was more DIY, without any investment in materials. i guess using the correct silicone mold it might work well
[07:47:30] <Loetmichel> ... for battlemechs...
[07:47:51] <cpresser> lol. tabletop-nerds^^
[07:48:02] <Loetmichel> worked ok, was a bit tricky to get the miniatures out of the silicone molds ;-)
[07:48:57] <archivist> http://www.clock-works.clara.net/cata/spa5.htm pictures do not do them justice
[07:49:28] <archivist> cast in brass
[07:52:30] <Jymmm> My trackball sits atop rubies. But the cheap plastic that holds the rubies deforms over time. I need to find a way to hold the rubies
[07:52:56] <Jymmm> Kingston Expert Mouse
[07:53:33] <Jymmm> Nothing else is actually wrong with the trackballs, just these damn thin/cheap mounts
[07:55:08] <Loetmichel> cpresser: not enough pressure... (your photo) make a longer "pour in tube" or use a "schleuderguss" ( two or more molds on a spinning disk, with the pouring tubes in the middle)
[07:55:17] <archivist> make bits by hand glue on, no casting needed
[07:55:27] -!- p0g0_ has quit [Ping timeout: 246 seconds]
[07:58:56] <cpresser> Loetmichel: the main problem was the mold. it was flat, not standing upright
[07:59:19] <cpresser> Loetmichel: i made it on OHM2013-hacker-camp. we had limited tools and supplies
[07:59:28] <cpresser> still, i learned a lot :)
[07:59:46] <Jymmm> It looks like one of the rubies has a "chip" out f it
[08:00:56] <Jymmm> I'm not sure what I could replace it with
[08:01:48] <cpresser> Jymmm: most likely you dont want another trackball. but i would recommend a 'logitech marble man' trackball. mine now works for more than 14years. in only replaced the left-mouse-button-switch
[08:01:57] <Jymmm> it's like a 1.5-2mm diameter ruby
[08:02:45] <Jymmm> cpresser: Heh, we've replaced 4 of those
[08:03:40] <Jymmm> cpresser: nowhere close the the smoothness and no scrollwheel/ring
[08:04:07] <cpresser> scrollwheel? nobody needs that :P
[08:04:22] -!- Simooon [[email protected]] has joined #linuxcnc
[08:04:27] <Jymmm> If I could do something like a ballpoint pen, that would work I eblieve
[08:04:56] <Jymmm> cpresser: I need more programmable buttons is what I need
[08:10:31] <MacGalempsy_> archivist: what do you get for those tiaras?
[08:10:45] <MacGalempsy_> i guess clock pieces
[08:11:03] <archivist> they fit on clock dials
[08:11:13] <MacGalempsy_> those are cnced?
[08:11:29] <archivist> no cast, copied from originals
[08:11:46] <MacGalempsy_> very cool.

[08:16:04] <archivist> that was work
[08:16:59] <archivist> my part on the dial was hole filling and engraving (hand)
[08:17:48] <MacGalempsy_> you do that kind of stuff everyday and tinker with cnc at home?

[08:18:12] <archivist> that was the day job that ended 2009
[08:18:40] <archivist> made the cnc at work to cut gears, but it was mine so came home
[08:19:50] <MacGalempsy_> so what do you do now for 9-5?
[08:20:22] <archivist> odd jobs, next to nothing
[08:23:26] <MacGalempsy_> sounds relaxing
[08:24:16] <archivist> stressed hungry and cold
[08:30:07] -!- archivist_herron [[email protected]] has joined #linuxcnc
[08:32:15] <MacGalempsy_> oh
[08:32:29] <MacGalempsy_> time to get the cnc fired up and start production :P
[08:32:48] <archivist> first one needs orders
[08:33:01] <MacGalempsy_> just go on ebay, find the most expensive, smallest machined part you can find, then duplicate it
[08:33:18] <MacGalempsy_> I say vintage aluminum chocolate molds can go for high dollar
[08:33:23] <archivist> you get orders advertise, to advertise get money...ops loop detected
[08:34:08] <MacGalempsy_> http://pe.usps.com/text/dmm300/173.htm#1113509
[08:34:26] <MacGalempsy_> all it would take is a few decent replicas and you could be making $$$
[08:35:08] <MacGalempsy_> 19.5" rabbit went for over 2k
[08:35:48] <MacGalempsy_> 16" rabbit pisisng in a basket, 950! http://www.ebay.com/itm/Antique-Chocolate-Mold-Rabbit-Apron-Working-in-Basket-GIANT-BANQUET-16-HIGH-/130996075686?pt=LH_DefaultDomain_0&hash=item1e7ff97ca6
[08:36:39] <archivist> if not antique its not worth the money
[08:36:57] <MacGalempsy_> how do you know? just antique it :)
[08:37:07] <archivist> my cnc cannot make large items anyway
[08:37:34] <Jymmm> aluminum is like 50 bazillion years old, that's an antique, aint it?
[08:37:53] <MacGalempsy_> agreed!
[08:38:02] <archivist> any fraud gets you a holiday in prison, not worth it
[08:38:10] <MacGalempsy_> i mean, just make it in aluminum or tin, then throw it in saltwater for a few hourse
[08:38:51] <MacGalempsy_> here is another thing I was thinking would be good http://www.ebay.com/itm/HERTEL-Indexable-End-Mill-1-x-1-1-4-Shank-9-Inserts-3FL-ANGT1623-BN65-/270893193684?pt=LH_DefaultDomain_0&hash=item3f127e19d4

[09:56:13] <firstmill> basetread is set by stepconf to 100000 i did enter 15000 in the config
[09:56:30] <firstmill> stepconf = config
[09:59:21] <cpresser> firstmill: you can test each axis in stepconf
[10:00:18] <cpresser> firstmill: make sure you got you steppers to work with stepconf. then you can start to edit config-files directly
[10:06:22] <firstmill> it works in the testpanell but as i start the machine it fails on gcode stepper are stalling
[10:07:46] <firstmill> in the integreater manual it gives me other numgers or itesms to config then the stepconf made and as the sherline basic configuration has in it
[10:08:24] <firstmill> integrater Manual page 41 addf parport.0.read base-thread 1
[10:11:16] <archivist_herron> test your acceleration make sure its not too fast

[12:40:27] -!- skunkworks [[email protected]] has joined #linuxcnc
[12:41:08] <jthornton> morning, you make any headway?
[12:41:15] -!- kiw has quit [Ping timeout: 245 seconds]
[12:47:45] <MacGalempsy_> just a lot of reading and a better understanding of the hal code
[12:48:17] <MacGalempsy_> starting to see why you would just rather tweak the code after an initial setup
[12:48:47] <MacGalempsy_> also, I think the first tab that was a mystery are pins available to the 5i25
[12:49:27] -!- Tecan has quit [Remote host closed the connection]
[12:50:05] <jthornton> did my web page help any?
[12:50:54] <MacGalempsy_> the example 5i25 and 7i77 files looked good
[12:51:36] <MacGalempsy_> honestly, I just went back to the book and started going through cover to cover. went through the advanced hal manual first, now going through the integrators manual more thouroughly
[12:52:17] <MacGalempsy_> still need a few relays to show up, so maybe by the time those arrive, i will be ready to connect the rest and give a go at programming all the pins in one shot
[12:52:26] <jthornton> the basic hal section is a good place to start for hal
[12:52:52] <jthornton> ah no, it is better to program one pin at a time and test for typos
[12:53:22] <MacGalempsy_> so its not better to list all the pins then use halmeter to check the connections?
[12:54:03] <jthornton> well it is easier to find typos if you just add one pin at a time until you get good at it
[12:54:14] <MacGalempsy_> ah, agreed
[12:55:12] <jthornton> if you use show hal configuration from the Axis menu you can see all the pins and there is a watch window where you can watch multiple pins
[12:55:32] <MacGalempsy_> ok. do you have a recommendation on a handheld mpg for touchy?
[12:56:37] <jthornton> I use a standard MPG and use Mode 3 on the 5i25 to get the MPG inputs
[12:57:00] <MacGalempsy_> mode 3?
[12:57:09] <MacGalempsy_> is that the pins on the card?
[12:58:02] <MacGalempsy_> what do you think about the usb ones?
[12:58:14] <jthornton> no, it is an option on the config line
[12:59:33] <jthornton> I prefer a regular MPG connected directly to the 7i77, I use a USB joypad on my plasma but it does not require precise positioning
[13:00:09] <MacGalempsy_> when you say regular, do you mean a dial with two selectors?
[13:00:59] <jthornton> loadrt hm2_pci config="num_encoders=6 num_stepgens=1 sserial_port_0=300xxx"
[13:01:26] <jthornton> yes, the dial is the MPG and selector switches for distance per click and axis selection
[13:01:42] <jthornton> the 3 in the config puts the card in mode 3
[13:02:09] <MacGalempsy_> ah that is where ports 16-19 are used for mpg
[13:02:20] <jthornton> so if you take the sample 7i77 hal file and change to a 3 you get mode 3
[13:02:36] <MacGalempsy_> ok
[13:02:56] <MacGalempsy_> may have to do that on the 7i84 instead because the 7i77 is full

[17:19:30] <jmasseo> anybody ever convert a tree cnc mill to linuxcnc?
[17:19:45] <archivist> tree?
[17:19:50] <jmasseo> it's a brand
[17:19:59] <jmasseo> looks kind of like a bridgeport but it's not a retrofit
[17:20:00] <jmasseo> 2hp
[17:20:08] <archivist> never heard of them
[17:20:19] <cradek> the brand is not important. lots of people convert mills that are like 2hp bridgeports.
[17:20:37] <jmasseo> this one is already CNC, but it's got a dynapath conversational controller
[17:21:02] <skunkworks> it is more of a question - what hardware is in it and what can be reused
[17:21:06] <pcw_home> I think a t least a couple have been converted to LInuxCNC (older ones use resolvers for axis feedback)
[17:21:12] -!- theorbtwo has quit [Remote host closed the connection]
[17:21:34] <jmasseo> the owner said it will intermittantly skip 0.010 on the X
[17:21:40] <jmasseo> and he believed it to be a controller issue.
[17:21:46] <jmasseo> otherwise it's in a ship shape
[17:21:53] <jmasseo> apart from being 27 years old
[17:22:04] <pcw_home> might be a dirty encoder
[17:23:31] -!- IchGuckLive [[email protected]] has joined #linuxcnc
[17:23:45] <archivist> whatever it is, sounds like a suitable starting point to make a usable mill
[17:24:46] <jmasseo> 3k USD and 2.5 tons
[17:24:53] <jmasseo> not counting rigging
[17:25:02] <IchGuckLive> hi all B)
[17:25:29] <archivist> something like http://www.szpakmfg.com/tree.html ?
[17:25:30] <_DJ_> hi mister live
[17:26:34] <IchGuckLive> _DJ_: a BAGGER has cut the internet so im only on 10kb/s hope the airtunnel can stand at that weather outside
[17:27:03] <_DJ_> oh
[17:27:09] <IchGuckLive> O.O
[17:27:09] <_DJ_> 10 kb/s is evil...
[17:27:23] <jmasseo> i think this one is slightly older
[17:27:29] <jmasseo> than the one you linked
[17:28:05] <_DJ_> get LTE or so ;-)

[17:33:50] <jdh> there are several chaeper than that on ebay

[17:34:30] <archivist> but the price was right, free delivered
[17:35:10] <jdh> all inexpensive mills seem to be located far away in godforsaken areas.
[17:35:54] <archivist> trailers are useful
[17:36:22] <jdh> I'm not driving to Kansas for anything.
[17:37:13] <archivist> my lathe was about 300 miles away, was a fun drive
[17:37:21] <jdh> I will admit my knowledge of kansas comes mostly from the wizard of oz.
[17:37:41] <cradek> kansas is adjacent to some really nice places
[17:37:42] <jdh> 300 miles would be fine. Less than 1k would be ok.

[18:07:44] <CaptHindsight> maybe someone has a front loader there

[20:37:00] <sirdancealot3> i dunno what that is, some module? when the machine is turned on, pressing f1 turns it off...thats all, no indication that it was an estop
[20:37:02] <sirdancealot3> but it works
[20:37:32] <Jymmm> I'm looking for around 3" OD, and 2.75" ID
[20:37:59] <sirdancealot3> the gui does indicate the hw push

[20:45:32] <CaptHindsight> Jymmm: suppliers list bearings on Amamzon lower than their own list prices, but only make 1-2 available at that discounted price
[20:45:50] <Jymmm> ah, well thats all I need =)
[20:46:52] <CaptHindsight> same for tools now, I picked up a $350 diamond coring bit for $50 on amazon and it shipped direct from the manufacturer

[22:03:34] <andypugh> Looks like it :-)
[22:03:53] <andypugh> Partly because the CAM cuts a lot of air (grump)
[22:04:22] <Tom_itx> i seldom use canned cuts when i do a model
[22:05:00] <Tom_itx> do all the cut offsets manually and stack em
[22:05:17] <Tom_itx> takes a bit longer but it's quicker on the machine
[22:06:56] <andypugh> What bugs me are the rapids to safe heigh follwed by a feed to the next waterline level. Why not rapid to the previous waterline level then feed?

[22:20:12] <andypugh> No, I am using the trial version of Meshworks (pretty good, actually, but I am not sure it is worth $250 to me)
[22:20:31] <andypugh> The partner cut simulator is fairly groovy too.
[22:21:35] <andypugh> I am happy enough with PyCAM in many ways, but it is just so exceptionally slow, ie overnight runs for paths that MeshCAM does in seconds.

[22:24:44] <Connor> I like CamBam.
[22:24:52] <KimK> Oh, really? I hadn't heard that about PyCAM. I've never used PyCAM except to turn it on, fiddle with it a little and then turn it off again. OK. Back in a bit.

[23:03:48] <maZer`-> does someone know a good gearbox or way for a 4th axis ?
[23:07:25] <Tom_itx> yeah mine has the safe clear height setting but i usually just leave it the same for all the tools
[23:08:06] <Tom_itx> unless it's a flat plate or such with a bunch of holes etc where i want it as short as i can safely get
[23:09:13] <maZer`-> ok
[23:10:02] <Tom_itx> maZer`- for what size mill?
[23:10:18] <maZer`-> also is a little bit bigger, is 400x400x400 way
[23:10:32] <Tom_itx> harmonic drives make good rotaries
[23:10:33] <maZer`-> but diameter of 4th axis should have something about 300mm
[23:10:44] <maZer`-> Tom_itx yes but its unpayable :(
[23:11:16] <Tom_itx> worm screws have backlash but there are plenty of them out there

[23:33:48] <FreezingCold> So this EMCO mill crashes when I load a pycam drawing (gcode, 11kb), but works fine with my manual drawings (gcode, 1kb)
[23:33:54] <FreezingCold> suggestions on whats wrong

[23:34:43] <andypugh> (Probably worth pointing out that the Emco isn't running LinuxCNC)
[23:34:54] <andypugh> Well, probably not. :-)
[23:35:37] <FreezingCold> True
[23:35:41] <FreezingCold> it's a retarded program
[23:35:48] <FreezingCold> but sadly that's what my college gives me =/
[23:36:29] <cradek> could be anything that's wrong with the gcode that tickles a bug or feature in the control. does it give you any clues? an error message? have you bisected the code to find the part that causes the error?
[23:36:39] <andypugh> If you need a workaround, you may be able to split the program.
[23:37:21] <andypugh> Though 11k is still pretty small, so I would be surprised if it was a size problem.
[23:39:06] <cradek> that is 90 feet of paper tape, which is a very long program for an old control. I think my boss8 bridgeport had 100 feet of ram.
[23:39:40] <andypugh> If you can measure it in feet, isn't it SAM?
[23:40:12] <cradek> well it actually had ram, and they specified it in feet, I shit you not

[23:45:59] <cradek> I happen to know that linuxcnc is running that mill now (I don't have it anymore)
[23:47:07] <cradek> I guess it had 12kB of RAM == 100 ft.

[23:54:29] <WalterN> its a fun machine
[23:57:28] <andypugh> I have a weldon-type tool holder. 16mm. Looks quite useful except the grub-screw is missing.
[23:57:55] <andypugh> That wouldn't normally be a problem. except it appears to be M14.
[23:58:51] <andypugh> I can't find M14 grub screws in any of the usual places. The only option seems to be to import 25 from Hong Kong.
[23:59:27] <andypugh> (Wierdly, they exist in the US too. Perhaps as a non-metric country the US is unaware that M14 doesn't exist :-)
