[02:00:49] <eric_u1> can I make a three phase motor from a single phase motor? http://www.cnczone.com/forums/showthread.php?t=23378
[02:20:22] <ds3> generally, no.
[02:20:54] <eric_u1> if you read that thread, some credible people chime in to say that the answer is "sometimes"
[02:21:03] <eric_u1> but usually not
[02:23:41] <ds3> I suppose you could cheap with the definition and drive it from a single phase
[02:24:02] <skunkworksemc> 3 phase motors are so cheap though...
[02:24:03] <skunkworksemc> why
[02:24:16] <eric_u1> true, people are giving them away
[02:25:34] <SWPadnos> skunkworksemc, I got the same part number as you did (the GOAL3+)
[02:26:16] <skunkworksemc> we must have bought them at around the same time.
[02:26:27] <SWPadnos> and this case/power supply: http://www.newegg.com/Product/Product.aspx?Item=N82E16811147099
[02:26:31] <SWPadnos> yes, we did
[02:26:37] <ds3> there are cases where the 1PH motor is really a 3PH motor with a cap to give you the shift for the 3rd leg
[02:33:23] <skunkworksemc> SWPadnos: http://imagebin.ca/img/CcIOjt9.jpg
[02:33:29] <skunkworksemc> my case.. :)
[02:33:57] <JymmmEMC> skunkworks Hey! where can I get a case like that with built in soldering iton
[02:34:12] <skunkworksemc> the camera did a nice job of stopping the fans.
[02:34:57] <SWPadnos> heh
[02:37:27] <skunkworksemc> wow - really these motherboards are nice
[02:37:36] <JymmmEMC> the %50 ones?
[02:37:39] <JymmmEMC> $50
[02:38:16] <skunkworksemc> http://imagebin.ca/img/Iyn-xxNl.png
[02:38:32] <skunkworksemc> 79 when I bought them
[02:38:55] <skunkworksemc> look at the task bar
[02:39:24] <JymmmEMC> Guess it's not THAT good afterall! lol
[02:39:32] <JymmmEMC> NO CARRIER
[02:39:40] <skunkworks> sorry - closed the wrong window
[02:39:59] <SWPadnos> bummer. no DWIM interface
[02:40:06] <JymmmEMC> dwim?
[02:40:12] <SWPadnos> Do What I Mean
[02:40:18] <JymmmEMC> Ah
[02:41:14] <skunkworksemc> * skunkworksemc just had too much stuff open and pictures of stuff open.. ;)
[02:41:23] <JymmmEMC> heh
[02:42:07] <skunkworksemc> still 6235
[02:42:35] <JymmmEMC> youtube it
[02:43:49] <skunkworks> youtube the latency test?
[02:44:11] <JymmmEMC> I meant play a video or four basically
[02:44:32] <JymmmEMC> http://video.yahoo.com/watch/3710199/10203309
[02:44:33] <skunkworks> heh - that makes more sense
[02:46:04] <eric_u> I had a fan on the router, but my wife thought it was too cold to be running a fan, so she turned it off and the router overheated
[02:46:35] <skunkworks> did you explain that the act of running the fan was actually heating up the area?
[02:46:52] <eric_u> good point, I'll have to remember that one
[02:51:34] <eric_u> there are a couple of unhappy bobcad users over at cnczone
[02:51:50] <SWPadnos> just a couple?
[02:51:54] <SWPadnos> must be a slow day :)
[02:52:12] <eric_u> it's sad they can't just sell the software
[02:52:20] <eric_u> people would probably be ok with it
[02:52:24] <SWPadnos> yep. most people complain about the pushy salespeople
[02:53:06] <eric_u> one of their fanbois has jumped ship
[02:53:32] <SWPadnos> interesting
[02:53:58] <skunkworksemc> http://imagebin.ca/img/ltRCwxW4.png
[02:54:22] <eric_u> skunkworksemc: I hate you now
[02:54:30] <skunkworksemc> heh
[02:54:40] <SWPadnos> for <$75, you could join him
[02:54:47] <SWPadnos> uh -us
[02:54:49] <eric_u> my wife would kill me
[02:55:05] <eric_u> actually, this computer is pretty close to that one
[02:55:11] <SWPadnos> tell her the fan caused damage you need this to repair
[02:55:45] <eric_u> you have an all sis chipset?
[02:56:16] <SWPadnos> yeah, the 961 or something
[02:56:23] <eric_u> so this is a different, nforce3
[02:56:47] <eric_u> I should run the livecd on it once I set up the new computer
[02:57:33] <skunkworksemc> http://pastebin.ca/1297450
[02:57:59] <skunkworksemc> I am using a pci-e ati video card (as you can see from the picture earlier)
[02:58:33] <eric_u> I didn't see nofink earlier
[02:59:52] <skunkworks> http://imagebin.ca/img/CcIOjt9.jpg
[03:00:19] <eric_u> your graphics card is half the size of your mobo
[03:01:10] <eric_u> hopefully ati starts coming out with decent linux drivers
[03:01:20] <eric_u> I'd expect that nvidia would open up then too
[03:01:27] <SWPadnos> the recent code and documentation drop should insure that soon
[03:01:33] <SWPadnos> for ATI
[03:01:37] <eric_u> of course, ATI had nothing to lose
[03:01:52] <LawrenceG> skunkworks, do you have newegg link on that m/b.... certainly one of the best latency tests I have seen
[03:02:04] <eric_u> you can't get it any more
[03:02:13] <SWPadnos> other than the GTX280, ATI is top of the heap performance-wise. they're definitely best price/performance at the moment
[03:02:23] <SWPadnos> eric_u, they're available again
[03:02:31] <eric_u> are we sure that's the same board?
[03:02:32] <SWPadnos> http://www.newegg.com/Product/Product.aspx?Item=N82E16813135227
[03:02:49] <SWPadnos> I'm pretty sure it's the same board, though as jmkasunich noticed, it may no longer have a CPU fan
[03:03:13] <eric_u> actually, since newegg takes paypal, I can buy it and my wife wouldn't notice :)
[03:03:27] <SWPadnos> heh
[03:09:17] <skunkworksemc> * skunkworksemc is running a 15us base period and everything seems snappy..
[03:09:30] <skunkworksemc> it woundn't to 10us.. ;)
[03:12:28] <skunkworksemc> http://imagebin.ca/img/JW3vGd.png
[03:13:47] <eric_unterhausen> I think the cold temps have reduced download speeds to a crawl
[03:13:54] <cradek> if you're optimizing for the fastest base period, you could remove parport.0.read. move it to servo. nothing acts on that information any faster than the servo thread anyway.
[03:14:38] <skunkworksemc> cool
[03:14:58] <cradek> well I suppose it needs to be in the base period if you have a jogwheel or something like that
[03:15:08] <skunkworksemc> right
[03:15:10] <cradek> but for steppers, limit/home switches, estop, nope
[03:16:22] <eric_unterhausen> Georgia Tech needs to take up basket weaving
[03:17:06] <eric_unterhausen> football is apparently not something they are interested in
[03:17:10] <skunkworksemc> I could read my 2540 line ecoders up to about 400 rpm.. ;)
[03:17:48] <skunkworksemc> or 1000 line ecoders up to 1000rpm/
[03:17:56] <skunkworksemc> assuming perfect everything... ;)
[03:18:37] <eric_unterhausen> skunkworksemc: with a parport?
[03:18:58] <skunkworksemc> I think I might have to let emc run all night and see if it throws out a rt error.
[03:19:08] <JymmmEMC> good idea
[03:19:41] <eric_unterhausen> put a $500 piece of aluminum in the machine to keep it interesting
[03:20:03] <skunkworksemc> eric_unterhausen: yes
[03:20:24] <eric_unterhausen> that's pretty good for a parport
[03:24:06] <skunkworksemc> I am saying that would be best case.. I think I should be able to read into the 50khz range though...
[03:27:00] <eric_unterhausen> you contemplating using emc for the control on your amp?
[03:27:34] <skunkworks> of cource. (but with pluto and then mesa.)
[03:28:57] <skunkworks> eric_unterhausen: http://www.youtube.com/watch?v=fGF07oVkl6M
[03:29:06] <skunkworks> previous version.
[03:29:22] <eric_unterhausen> haven't gotten flash working on this comp yet
[03:29:39] <skunkworks> heh - well this is pwm out of the printer port..
[03:29:41] <skunkworks> http://www.youtube.com/watch?v=eUmFKOVepYY&feature=channel
[03:46:06] <maddash> eric_unterhausen: what are you running?
[03:46:23] <maddash> eric_unterhausen: that prevents you from getting flash to work
[03:56:49] <eric_unterhausen> running new computer
[03:56:55] <eric_unterhausen> it's installed now
[03:57:21] <eric_unterhausen> the second link you provided is the new board, correct?
[03:59:45] <eric_unterhausen> I may have converted my son to linux by showing him the desktop effects :)
[04:22:32] <JymmmEMC> what desktop effects?
[04:50:12] <eric_unterhausen> compiz
[04:53:36] <eric_unterhausen> after the initial setup annoyances, ubuntu has been treating me pretty well
[04:54:04] <eric_unterhausen> got the windows printer working easily, no joy on my wife's windows computer
[04:55:46] <maddash> compiz
[06:03:01] <JymmmEMC> maddash: http://en.wikipedia.org/wiki/Compiz
[17:33:11] <Roguish> HAPPY NEW YEAR ALL!!!!!!
[17:33:32] <skunkworks> Happy New Year!!
[17:55:10] <Guest820> hello, is there documentation on how to setup a python enviornment to do something like the Axis helpers?
[17:56:53] <alex_joni> Axis helpers?
[17:57:09] <Guest820> facing, drilling.....
[17:57:25] <alex_joni> those aren't AXIS helpers afaik
[17:58:47] <Guest820> regardless, just want to be able to something along those lines
[17:59:30] <jmkasunich> python is an interpreted language - you don't really need an "environment", you just need the python interpreter
[17:59:36] <skunkworksemc> like this? http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Simple_EMC_G-Code_Generators
[17:59:58] <Guest820> yes g-code generators
[18:00:28] <Guest820> how was the windows setup in Qt?
[18:00:57] <jmkasunich> Qt?
[18:01:02] <jmkasunich> axis doesn't use qt
[18:01:11] <jmkasunich> I'm not sure what those g-code generators use
[18:01:50] <Guest820> all I want to do is setup an enviornment to be able to do something similar
[18:02:17] <jmkasunich> do you have axis and those g-code generators working on your computer?
[18:02:25] <jmkasunich> (they should be, if you have EMC installed)
[18:02:29] <Guest820> yes
[18:02:51] <jmkasunich> ok, then everything is set up already
[18:03:00] <jmkasunich> just copy one of the generators and start editing
[18:03:35] <eric_u> I think those things should all be renamed after the "arc buddy", in particular, the "bezel buddy"
[18:03:39] <Guest820> but I don't know whre to find the widget documentation
[18:03:49] <jmkasunich> try google
[18:04:00] <jmkasunich> just google the various widget names
[18:07:17] <skunkworksemc> jmkasunich:wow - there are a lot more gcode generators on that page now.
[18:07:22] <skunkworksemc> heh
[18:07:45] <eric_u> yeah, put that together behind a big dialog box and call it a wizard
[18:08:10] <skunkworksemc> jmkasunich: that wasn't necessarily directed to you.. ;)
[18:08:31] <skunkworksemc> what I was going to say is that I love this motherboard.
[18:08:32] <jmkasunich> ;-)
[18:08:33] <jmkasunich> I haven
[18:08:43] <jmkasunich> haven't looked at those much
[18:09:22] <JymmmEMC> LawrenceG: ping
[18:10:17] <JymmmEMC> Heh, I like the licensing
[18:10:36] <eric_u> Guest820 is starting to take on a personality
[18:11:35] <JymmmEMC> Who's John Thorton?
[18:11:44] <skunkworksemc> bigjohn
[18:11:59] <JymmmEMC> Ah, nice.
[18:12:06] <eric_u> He learned python and went to town
[18:12:18] <JymmmEMC> are you serious?!
[18:12:23] <skunkworksemc> :) and has been updating the docs tons.
[18:12:57] <LawrenceG> JymmmEMC, pong
[18:13:02] <jmkasunich> JymmmEMC: yes, he's been doing tons of work on the docs
[18:13:11] <JymmmEMC> Damn fine work
[18:13:13] <jmkasunich> I forget that most people don't see the commit list traffic
[18:13:16] <JymmmEMC> LawrenceG: HNY!
[18:14:01] <jmkasunich> http://cia.vc/stats/author/bigjohnt
[18:14:36] <jmkasunich> http://cia.vc/stats/project/emc
[18:14:42] <LawrenceG> JymmmEMC, same to you ... I guess I am officially retired... resigned from P.Eng. registration... was getting to be a real PITA
[18:14:55] <eric_u> looks like his production was low between Christmas and yesterday, someone will have to talk to him
[18:15:22] <JymmmEMC> LawrenceG: registration?
[18:16:28] <LawrenceG> a send money, be happy type of society
[18:16:46] <JymmmEMC> LawrenceG: AH, lol
[18:17:00] <JymmmEMC> The design is kinda cool... http://www.freelancelogodesigner.com/
[18:17:18] <LawrenceG> nice to be off the "please sue me" list
[18:18:03] <JymmmEMC> LawrenceG: P.eng being python?
[18:18:29] <eric_u> professional engineering?
[18:18:31] <LawrenceG> professional engineer
[18:18:53] <JymmmEMC> LawrenceG: So you downgraded to hobby engineer?
[18:19:02] <LawrenceG> :}
[18:19:31] <eric_u> LawrenceG: are you a civil engineer?
[18:19:38] <LawrenceG> maybe need to start a new society... unprofessional engineers... sounds kind of "dirty"
[18:20:08] <LawrenceG> computer engineering, but was trained as a metallurgist
[18:20:22] <eric_u> after 30 years, I guess I'm still an "engineer in training", cause I never took the PE exam
[18:21:13] <skunkworksemc> eric_u: 30 years? how old are you? I for some reason thought you where in your 20s
[18:21:34] <eric_u> skunkworksemc: http://www.newegg.com/Product/Product.aspx?Item=N82E16813135227 new rebate
[18:21:37] <eric_u> I'm 50
[18:22:44] <eric_u> but I guess I seem younger because of my childlike sense of wonder, or childish sense of humor
[18:24:17] <skunkworksemc> eric_u: are you buying?
[18:24:47] <eric_u> not right now, I am wondering what gives that mobo such low latency
[18:24:50] <JymmmEMC> What are those USB things that can hold files called?
[18:25:03] <eric_u> flash drives?
[18:25:15] <skunkworksemc> thumb drives. keychain drives,
[18:25:25] <skunkworksemc> pen drives
[18:25:33] <eric_u> zip drives
[18:25:44] <skunkworksemc> spam, spam, spam, spam
[18:26:28] <JymmmEMC> Ok, it was a loaded question.... I wanted to see what ppl are calling them as they go by so many names... thumbstick is another.
[18:27:35] <JymmmEMC> any others that you guys can think of?
[18:29:38] <skunkworksemc> usb thingey
[18:30:38] <JymmmEMC> heh
[18:30:38] <skunkworksemc> This will be my new pcb mill. http://imagebin.ca/img/huFdB7t1.jpg
[18:31:09] <eric_u> have you seen the mod where someone put a flash drive into a broken usb cable? I have a flash drive with a broken case I'm thinking about doint that with
[18:31:09] <cradek> what is it?
[18:31:16] <JymmmEMC> what was it?
[18:31:41] <JymmmEMC> eric_u: I think thinkgeek has that
[18:31:41] <skunkworksemc> it was a xyz table for despencing liquid.
[18:31:46] <JymmmEMC> ah
[18:32:12] <skunkworksemc> but it needs some work - it is like .007 per step as setup. way to low
[18:32:24] <eric_u> is it upside-down?
[18:32:55] <skunkworksemc> yes - sort of. that is how it was setup - bit could be setup anyway
[18:33:28] <skunkworksemc> the plate between the electronics and the axis is not installed
[18:34:39] <skunkworksemc> here is it running with the dispensing software.. http://www.youtube.com/watch?v=zKZYj51Exn0&feature=channel
[18:34:46] <eric_u> I'm gathering that the y position is determined by the differential motion between those two fixed steppers?
[18:35:39] <skunkworksemc> no - it is cable run. The way it is setup (which is cool) is the cables are routed so they are totally independent of one another
[18:36:20] <skunkworksemc> x stepper runs x axis/cables and y stepper runs y axis and cables
[18:36:45] <skunkworksemc> I think I can get this thing to zip around pretty fast.
[18:37:27] <eric_u> I have a couple of small plotters that were run by cables, it was neat
[18:37:33] <eric_u> only problem is no z
[18:38:32] <eric_u> newegg still has an athlon socket A motherboard, problem is it takes DDR
[18:40:05] <skunkworksemc> it needs a reduction - or replace the cables with screws. the thing is very solid as is though..
[18:40:52] <jmkasunich> newegg raised the price
[18:40:55] <jmkasunich> $3
[18:41:05] <eric_u> what was it, a cake decorating machine?
[18:41:36] <jmkasunich> probably adhesive or something
[18:41:56] <skunkworksemc> we used it for applying a clear domed liquid to the top of decals
[18:42:52] <skunkworksemc> it was uv cured so it really sucked for durability. we now use a 2 part epoxy like liquid
[18:43:14] <skunkworksemc> others use it for potting and such.
[18:45:19] <skunkworksemc> the way it is setup now with cables - there would be virtually no backlash.
[18:45:39] <skunkworksemc> I would just need a 7 to 1 reduction or so ;)
[18:48:01] <eric_u> what are the ribbon cables for?
[18:48:55] <skunkworksemc> this had it's own motion board in it.
[18:49:08] <skunkworksemc> jog buttons and such
[18:49:51] <eric_u> put servos in there :)
[18:50:06] <eric_u> are those nema 17?
[18:53:37] <skunkworksemc> I don't know my sizes.. the flange is about 2.25X2.25
[18:54:15] <eric_u> what do I search for to figure out how to install emc as a simulator on my desktop?
[18:54:30] <eric_u> skunkworksemc: I think that's nema 23
[18:54:58] <skunkworksemc> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#Building_emc2_simulator
[18:56:37] <skunkworks> I think you would need some pretty hefty servos to run direct..
[18:57:06] <eric_u> you don't have much space
[18:57:12] <skunkworks> no.
[18:57:34] <eric_u> putting those cable drives back together is not a happy task though
[18:57:55] <skunkworks> I know.. :)
[18:59:04] <eric_u> have you done it successfully?
[19:00:13] <skunkworks> yes - a long time ago - this machine got a decal stuck in one of the idler pullys. (I have no clue how it happend) and poped it off. everything came undone ;)
[19:01:35] <JymmmEMC> skunkworks Heh, take pic so you can remember how it goes back together and toss under the cover =)
[19:01:53] <skunkworks> exaclty!
[19:02:49] <eric_u> you could use the steppers for their bearings and rig up another set of motors to drive them
[19:03:08] <skunkworksemc> still 7 to 1 is quite a reduction..
[19:03:37] <eric_u> I have gearboxes in my junk collection
[19:03:52] <skunkworksemc> .... and keep backlash low..
[19:04:01] <jtr> logger_emc: bookmark
[19:04:01] <jtr> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-01-01.txt
[19:04:33] <eric_u> I don't know how bad those gearboxes they mount on servomotors are
[19:04:48] <JymmmEMC> OT: I'm making a list of all the various distros, their variations (32bit, 64bit, live, etc, versions, etc. Anyone have an idea on catagorizing them so most would know where to look to find what they're after?
[19:04:50] <eric_u> I have one harmonic drive that fits on a nema 23
[19:04:59] <skunkworksemc> nice
[19:06:02] <eric_u> JymmmEMC: is that a trick question?
[19:06:03] <skunkworksemc> hmm - I should work on cleaning the basement.
[19:10:47] <dgarr> JymmmEMC: http://en.wikipedia.org/wiki/Comparison_of_Linux_distributions
[19:13:43] <skunkworksemc> wow - I really should start using firefox.. It has spell check when you are replying to messages on forums.. (I need that)
[19:14:21] <JymmmEMC> eric_u: Actually, no it's not.
[19:15:35] <JymmmEMC> eric_u: Consider: Ubuntu 32bit v8.04 desktop livecd as example
[19:16:45] <JymmmEMC> dgarr: thanks for the link
[19:17:11] <dgarr> np, distrowatch.com may be helpful too
[19:20:16] <JymmmEMC> It's a lil difficult to have a hierarchy with so many options
[19:21:32] <eric_u> compgeeks has a bicycle helmet cam, I need 2 for the accident investigation after I get run over
[19:21:48] <JymmmEMC> Considere using labels like google does, but no structure
[19:22:00] <eric_u> use a tag cloud
[19:22:11] <JymmmEMC> like keywords?
[19:22:37] <eric_u> yes, but call your keywords "tags" to keep everyone a little confused
[19:22:55] <JymmmEMC> but no struture there for general display

[19:28:05] <JymmmEMC> eric_u: I like the idea of a tag cloud, but not sure how to dispaly in a struture for those just browing )so to speka)
[19:28:34] <eric_u> I didn't really follow what you were after, so I can't help
[19:29:01] <eric_u> I have to admit, those tag clouds just make MEGO
[19:29:32] <JymmmEMC> eric_u: If you KNOW what you are looking for, the tag cloud works great. But if you just wanted to browser to see whats available and try something out, how to display it in a nice structure.
[19:30:22] <JymmmEMC> Example: Linux/Ubuntu/32bit/Desktop/version 8.04 LTS (simple enough)
[19:31:21] <JymmmEMC> Example: Linux/Ubuntu/UbuntuCE/32bit/LiveCD/8.xx
[19:32:06] <JymmmEMC> When you toss in all the variants, it gets a tad confusing
[19:33:07] <JymmmEMC> eric_u: Heh, I have one that'll REALLY confuse you =)
[19:33:36] <eric_u> not too hard
[19:34:06] <JymmmEMC> eric_u: Pretend you have a dating website, now how do you list the orientation of the person?
[19:34:50] <eric_u> horizontal or vertical
[19:34:51] <JymmmEMC> that they can choose from
[19:35:15] <JymmmEMC> eric_u: sexual orientation
[19:37:21] <JymmmEMC> eric_u: well?
[20:30:14] <fragalot> fragalot is now known as Guest80886

[21:26:30] <cradek> did everyone enjoy their extra 1 second of sleep last night?
[21:28:12] <Memocjr1> well, i enjoyed more than 1 second of sleep in the morning, i still have a heavy head after last night
[21:28:18] <Memocjr1> Memocjr1 is now known as Memocjro
[21:31:49] <skunkworks> a whole 1 second?
[21:31:50] <skunkworks> Nice
[21:40:28] <jepler> cradek: it didn't happen during the night for people in north america like you
[21:40:37] <cradek> oh, right
[21:40:42] <cradek> duh
[21:42:52] <ds3> what about the extra 1 second of partying?

[22:27:59] <skunkworks> JanVanGilsen: cool :)
[22:28:22] <LawrenceG> cool.... how about a pointer hack to a long diamond shape?
[22:29:42] <JanVanGilsen> LawrenceG: can you explain?
[22:30:57] <LawrenceG> JanVanGilsen, using 4 lines instead of 1... like an old clock hand.... I'll see if I can find a picture
[22:35:51] <LawrenceG> http://simple.wikipedia.org/wiki/File:Wall_clock.jpg sort of like those clock hands
[22:37:53] <JanVanGilsen> seems doable
[22:42:02] <JanVanGilsen> I'm also trying to figure out how to get rid of .0 on the scale, imo 6 is nicer and easyer to read then 6.0
[22:42:02] <eric_u> how about adding the legs from the clock spider http://www.google.com/search?hl=en&q=clock+spider&btnG=Google+Search&aq=0&oq=clock+sp
[22:48:00] <JanVanGilsen> someone who want to test this code?
[22:52:12] <eric_u> Thinking about using a shorter version of this rodless cylinder for a z axis on a pcb mill, any thoughts? http://cgi.ebay.com/Pneumactic-cylinders-rodless-smc-ncy2s32h-pair_W0QQitemZ120354426935QQ

[22:59:27] <JanVanGilsen> well, I'm off to sleep...
[23:03:48] <jepler> JanVanGilsen: neat -- you might drop a note on the mailing list about this too
[23:24:27] <skunkworksemc> http://www.youtube.com/watch?v=OphzjtNW2-o
[23:24:39] <skunkworksemc> neat spindle also :)
[23:27:21] <jepler> it's a little bigger than mine
[23:27:29] <jepler> I hate to have to admit that on the internet
[23:28:18] <cradek> is it moving?
[23:28:38] <eric_u> interesting
[23:29:24] <jepler> cradek: it's doing arcspiral, so it's moving only a few inches..
[23:29:45] <jepler> (or spiral, can't tell which)
[23:29:48] <eric_u> curious what the goals are for that machine
[23:30:15] <skunkworksemc> hey - look at this :) http://www.youtube.com/watch?v=P7IZJC4pyY4
[23:33:01] <eric_u> skunkworksemc: how hard is that to do with a Mesa?
[23:33:48] <skunkworksemc> I have not actally plugged in a mesa card yet.. But I would think just as easy.
[23:34:08] <jepler> cool
[23:37:25] <eric_u> I didn't have the sound up for the "linux cnc machine" -- that thing sounds freaky
[23:39:17] <eric_u> I bought a set of 4 l297/8 boards from Phil in Mo, and the price of l297s has kept me from building them. I'd rather put the $60 towards something better
[23:41:41] <fragalot> me?
[23:54:56] <eric_u> not that there is anything wrong with the boards, I'm just not a big fan of the chips
[23:58:56] <topls64> where can i find a list of known-good motherboards for emc. Starting to troubleshoot why my latency has gone from 14k to 128k+
[23:59:21] <topls64> after some upgrading
[23:59:29] <SWPadnos> there's a list of test results on the wiki, but I doubt anyone will ever say that a particular motherboard is "known good"
[23:59:39] <JymmmEMC> topls64: what did you "upgrade"?
