[00:05:10] <skunkworks> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-03-07.txt
[00:05:46] <skunkworks> http://www.youtube.com/watch?v=P1G6HP6bH1w&feature=related
[00:06:36] <skunkworks> damn nvidia
[00:09:50] <SkinnYPuppY> I've got a friend doing that but don't think he was using Yellow Dog
[00:26:19] <BigJohnT> hmmm http://i47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/Plasma010.jpg
[00:27:26] <BigJohnT> there's your pretty pictures
[00:53:35] <skunkworks> cool. :)
[00:54:46] <eric_U> how come it draws the lines between the letters?
[00:54:54] <BigJohnT> no Z yet
[00:55:08] <BigJohnT> just holding a pencil with my fingers
[00:55:09] <eric_U> didn't think of that
[00:55:36] <BigJohnT> you ever wrap masking tape around a pencil till it's 1" in diameter?
[00:55:45] <BigJohnT> it's a PITA
[00:55:56] <eric_U> I'd be wishing my lathe worked the entire time
[00:56:19] <BigJohnT> I wish my lathe was CNC
[00:57:59] <BigJohnT> I'm drawing up the Z axis as we type
[01:02:16] <skunkworks> all you need is a big solinoid... Click click click click ;)
[01:02:55] <BigJohnT> lol yep that might break my #2 pencil tip
[01:34:31] <JymmmEMC> BigJohnT: No, but the paint on a #2 pencil is VERY flammable!!! Gives a very cool look to it too after you burn it off.
[02:45:29] <DanielFalck> tomp2: can you email me your company contact info?
[03:14:37] <tomp2> DanielFalck: get my IM?
[03:19:36] <tomp2> just debugged a C axis that had worm and ring drive. encoder was on worm. customer lost motion, there was axial play on the worm. it would move a bit like a piston, without rotating, then began turning!
[03:23:34] <DanielFalck> tomp2: sorry, didn't get the IM
[03:23:34] <DanielFalck> my company is looking for a wire edm
[03:24:31] <tomp2> gimme hint on email?
[03:24:39] <DanielFalck> come over to #cam
[03:24:53] <tomp2> yep
[03:25:01] <cradek> anyone know anything about diesels?
[03:27:29] <SkinnYPuppY> I speak some auto diesel
[03:29:01] <cradek> I'm working on a 3-cylinder generator that looks to me like a small car engine
[03:29:31] <cradek> it has air flow, glow/heat on the intake, and fuel supply. cranks nicely but won't start
[03:29:46] <cradek> can you normally hear the injectors fire with a stick to the ear, like on a gas car?
[03:30:42] <SkinnYPuppY> Some may chatter a little, but any airpockets compress and you don't overcome the popoff pressure on the nozzle
[03:31:14] <cradek> so they don't have a loud click or anything you'd expect to hear sharply?
[03:31:28] <cradek> on a gas car you can hear them VERY well
[03:31:35] <SkinnYPuppY> If you have a means of vaccum , pull a vac on the fuel return . No not a loud click
[03:32:37] <cradek> not sure I can do vacuum. it does have two lines going to the fuel. one is return for pressure regulation?
[03:33:50] <jtr> vacuum line from idling car engine?
[03:33:53] <cradek> also it has the high pressure metal lines going to the tips of the injectors. At the base of the injectors there is also rubber lines, hooking them all together, that seem to have fuel in them. What are these?
[03:33:55] <SkinnYPuppY> Hmmm does it have three hard lines from the pump to the injector and an additional return line off the injector head?
[03:34:22] <SkinnYPuppY> Rubber lines are return for volume not consumed
[03:34:24] <cradek> the only hard lines are from (what I guess is the) injector pump to the ends of the injectors
[03:34:38] <cradek> ah ok, that makes sense
[03:34:53] <SkinnYPuppY> OK crack those loose at the injector and crank over
[03:35:21] <SkinnYPuppY> if you can't pull a vac on the returns this will prime out some of the air
[03:35:22] <cradek> crack which? the rubber or hard ones?
[03:35:31] <SkinnYPuppY> Hard lines at the injector
[03:35:56] <cradek> aren't those like a million psi?
[03:36:12] <SkinnYPuppY> only if they can build psi
[03:36:18] <cradek> dang I wish I had taken some pictures of it
[03:37:08] <SkinnYPuppY> Volume per stroke is so small it will seem like a small dribble when you get the air out.
[03:38:03] <cradek> ok so this air thing is a common problem for something that hasn't run for a while?
[03:38:30] <SkinnYPuppY> Sure they can loose prime or loose a front pump seal killing the prime
[03:39:09] <cradek> this engine is oldish (93) but barely used. I don't know when it ran last. Probably at least 2 years ago.
[03:39:49] <SkinnYPuppY> http://www.cs.rochester.edu/u/jag/vw/engine/fi/YANMARVESmall2.GIF
[03:41:20] <cradek> how high is the fuel pressure normally feeding the injector pump?
[03:42:13] <SkinnYPuppY> I set the popoff pressure on my trooper injectors at 1950 lbs
[03:42:39] <cradek> I mean the incoming fuel
[03:42:58] <cradek> I think there's a little fuel pump on the engine, no pump in the tank
[03:43:16] <SkinnYPuppY> Oh feeding the pump according to the pump maybe 3 to 5 psi for a lift pump
[03:43:50] <cradek> after the thing I think is the fuel pump, it goes to a glass bowl filter with four connections
[03:44:02] <cradek> two to the injector pump, one (return?) to the tank
[03:44:55] <SkinnYPuppY> Sounds like return yes , I'm not sure what your junction is a filter or a water separator maybe ?
[03:45:00] <cradek> the thing I think is a fuel pump has a small lever I can press and hold. It springs back when released. It is meant to be operated manually like that. What could it be?
[03:45:21] <cradek> yes I think it's just a filter, there's a big water separator earlier in the system
[03:45:24] <SkinnYPuppY> luckily its a prime lever !
[03:45:42] <cradek> interesting! how do I use it?
[03:46:31] <SkinnYPuppY> Should it be run dry, the one on my truck just pumps up and down, this will get fuel to the pump. But you can still have some air in the high pressure lines
[03:47:06] <cradek> oh so I should press it several times. I was holding it and cranking, which seemed to do nothing.
[03:47:16] <cradek> this is very helpful, thanks
[03:47:33] <SkinnYPuppY> Sure thing cradek , that does sound like a prime lever to me
[03:47:46] <cradek> I'm pretty smart with gas cars, but feel like a moron here :-)
[03:48:18] <cradek> ok I will try that. it did squirt a little gas out of the open line when I pressed it. I bet it is definitely a primer.
[03:48:31] <SkinnYPuppY> naaah most people that ask don't know the difference b/t pressure and volume
[03:48:53] <cradek> this also had a problem with the glow circuitry. that may have been what "killed" it a few years ago
[03:49:11] <cradek> it's no fun when you fix one problem and it still doesn't work!
[03:50:38] <SkinnYPuppY> I didn't use the glow circuit when I rebuilt the engine and broke in on the ground.. ~20 seconds cranking time the prechamber area gets hot enough to self ignite
[03:50:52] <SkinnYPuppY> Compression ignition
[03:51:18] <cradek> I was surprised this heats the intake air. there are not glow plugs.
[03:52:09] <cradek> it was nearly 40 degrees today. I think it could have started without glow if everything else was right?
[03:52:25] <SkinnYPuppY> Probably so
[03:52:57] <SkinnYPuppY> Dipstick heater or block heater is nice too
[03:53:14] <cradek> yes it has those too
[03:53:46] <SkinnYPuppY> It should be fine after a prime
[03:54:16] <cradek> so I should prime with the lever, and then pull each of the hard lines and crank until I get a dribble out of them?
[03:54:42] <SkinnYPuppY> If the lever doesn't do it open the hardlines 1/2 turn all together till ya get a dribble.
[03:55:02] <cradek> oh just loosen the nut a bit and it will ooze out?
[03:55:20] <SkinnYPuppY> Yeah it's a banjo fitting on the hardline at the injector
[03:55:27] <SkinnYPuppY> most likely that is
[03:55:40] <SkinnYPuppY> works same for flare
[03:55:52] <cradek> ok I see
[04:06:54] <SkinnYPuppY> bbl hope that works out cradek
[04:07:00] <cradek> thanks again
[04:07:05] <SkinnYPuppY> sure
[04:07:05] <cradek> I'll sure let you know
[04:07:14] <SkinnYPuppY> k cya
[04:38:06] <eric_U> in general, do debian packages install on ubuntu
[04:38:39] <eric_U> curious about this: http://wiki.debian.org/EmdebianToolchain
[04:38:58] <cradek> you can try, but not really.
[04:39:27] <eric_U> I'd hate to have to install debian, last time I tried, it was a nightmare
[04:39:59] <cradek> I bet you can rebuild the packages from source and get working debs
[04:40:07] <toastydeath> i like debian!
[04:40:13] <cradek> you may have to tweak the list of dependencies
[04:40:17] <eric_U> that's because you are nightmareish
[04:41:15] <eric_U> I got so many things to do, probly not worth it right now
[04:41:25] <toastydeath> THIS
[04:41:25] <toastydeath> IS
[04:41:27] <toastydeath> SPARTAAAA
[04:41:36] <toastydeath> i install debian base on the netinst cd
[04:41:42] <toastydeath> and just install bare minimum packages
[04:41:55] <toastydeath> fluxbox and some web apps
[04:42:25] <eric_U> mostly I didn't like it because installing debian was so crude, musta gotten better
[04:42:59] <toastydeath> ?
[04:43:14] <toastydeath> isn't it still a bunch of ncurses things
[04:43:24] <eric_U> I was hoping it wasn't
[04:43:46] <eric_U> any installer where I have to type a thesis is too much work nowadays.
[04:43:56] <eric_U> I wanna click next a few times and be done
[04:44:12] <SWPadnos> eric_U, you could try installing emdebian-tools
[04:44:26] <SWPadnos> which is in an Ubuntu repository (for 7.10 anyway)
[04:48:02] <eric_U> don't seem to have a package for 6.06
[04:48:46] <eric_U> I guess hoping for a fedora package is too much to hope
[04:48:53] <SWPadnos> you might get somewhere by looking at the package dependencies on 7.10
[04:49:12] <SWPadnos> or just get makecross (or crosstool or whatever it's called now) and build away
[04:51:02] <SWPadnos> ah - http://kegel.com/crosstool/
[04:54:46] <eric_U> I need to build up another computer with ubuntu on it
[05:14:28] <SkinnYPuppY> I did a debian 4 install on a virtual machine a few days ago. It was really easy on the install.
[05:58:56] <ChanServ> [#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website: http://www.linuxcnc.org/, wiki at http://wiki.linuxcnc.org/"
[06:47:37] <eric_U> I just compiled something, and it completed without error
[06:47:46] <eric_U> but it was not supposed to do that
[07:44:02] <alex_joni> damn bugfree software
[11:41:12] <jlmjvm> alex_joni:can the amount of look ahead be changed in emc?
[12:08:16] <archivist> got an interesting job today cradek google "merlin band clock" this one not to well built/assembled , just needs proper finishing and squaring up as far as I can see
[12:21:15] <alex_joni> jlmjvm: hmm, you can probably limit it
[12:21:28] <alex_joni> but only hackerish, and I know of no simple way of extending it
[12:22:12] <alex_joni> archivist: http://www.clockmaker.it/fotoorologi/8giorni/4/foto04pop.jpg like that?
[12:22:27] <archivist> yes
[12:22:33] <alex_joni> cool :)
[12:23:31] <alex_joni> guess you know Dave West Clocks in suffolk?
[12:23:46] <archivist> there seems to be a book about, this one came as parts went to a dumb clockmaker who could polish but not get things straight and the correct clearances
[12:24:16] <alex_joni> archivist: book: http://www.antiqbook.nl/boox/gys/W1372-4866.shtml
[12:25:45] <archivist> yup and seems to have been republished
[12:25:48] <alex_joni> that's a really awsome clock http://www.clockmaking-brass.co.uk/merlin-band-2.jpg
[12:27:41] <jlmjvm> alex_joni:how much look ahead does emc have,havent been able to find any info on the wiki
[12:28:59] <archivist> alex_joni, I shall have to take a better pic of this one, they look good on the flesh
[12:37:33] <jlmjvm> BigJohnT:hows the plasma cutter coming along
[12:38:33] <BigJohnT> good I'm done with the X and Y and have a jury rig to hold the plasma torch for some testing
[12:38:42] <BigJohnT> working on the Z axis now
[12:39:37] <archivist> "jury rig" ==finished and werkin :))
[12:40:03] <archivist> well thats what it seems to mean here sometimes
[12:40:21] <BigJohnT> temp for testing only
[12:40:52] <BigJohnT> jlmjvm: did you upload your ini and hal files for the steppers with encoders on wiki?
[12:41:28] <BigJohnT> I thought that was an interesting article
[12:41:28] <alex_joni> archivist: 'nother book http://www.clockmaking-brass.co.uk/merlin%20clock.html
[12:41:56] <alex_joni> jlmjvm: in what do you define lookahead?
[12:42:03] <alex_joni> g-code lines? segments?
[12:42:05] <alex_joni> seconds?
[12:42:09] <alex_joni> servo cycles?
[12:42:11] <archivist> yes Im not too impressed with J wilding (met him)
[12:42:15] <jlmjvm> g-code lines
[12:42:24] <alex_joni> jlmjvm: can't answer that
[12:42:34] <alex_joni> you can have 10 g-code lines and still mill 24h
[12:42:42] <alex_joni> if you have an O-word loop for example
[12:42:55] <BigJohnT> http://i47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/Plasma010.jpg
[12:43:00] <jlmjvm> BigJohnT:no i havent uploaded them yet
[12:43:58] <jlmjvm> do you need a copy,can paste them
[12:44:30] <BigJohnT> no, just wondering
[12:44:38] <jlmjvm> k
[12:44:44] <jlmjvm> pic looks good
[12:45:13] <BigJohnT> thanks
[12:50:28] <BigJohnT> might get to test is this weekend on a sheet of 10 ga
[12:51:00] <BigJohnT> I have to make coffee and bullet boxes for a duck blind
[12:51:12] <alex_joni> jlmjvm: also.. you must consider g-code cycles (like drilling) and such
[12:51:25] <alex_joni> the idea is that the trajectory planner is the one that does lookahead
[12:51:36] <alex_joni> it works on segments though (lines and arcs)
[12:52:48] <alex_joni> #define TP_DEFAULT_QUEUE_SIZE 32
[12:53:00] <alex_joni> I *think* that one might be the one you're after
[13:08:01] <Guest188> Guest188 is now known as skunkworks_
[13:24:03] <jlmjvm> alex_joni:i think that may be it,should that be added to the traj planner section in the .ini file?
[13:25:11] <jlmjvm> trying to get smoother motion when cutting a surface with a lot of x y z points from a cam system
[13:47:00] <skunkworks_> have you tried G64 Px.xxx ?
[13:47:10] <skunkworks_> logger_emc: bookmark
[13:47:10] <skunkworks_> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-03-07.txt
[13:48:38] <jlmjvm> skunkworks:is that the path tolerance
[13:54:05] <jlmjvm> trying that right now
[13:57:43] <skunkworks_> also - if your machine has pretty low accelleration - it will be herkey jerky
[13:59:00] <jlmjvm> that does make a difference
[13:59:13] <jlmjvm> the accel is fine
[14:01:33] <skunkworks_> yes it is path tolerance (didn't see that question..)
[14:04:19] <skunkworks_> If I understand it - with out path tolerace - it tries to touch every line. With it - it blends lines togather that are within the specified tolerance.
[14:14:09] <archivist> alex_joni, www.archivist.info/merlin
[14:15:48] <jlmjvm> skunkworks_:G64P0.005 make a heckufa diff
[14:17:30] <skunkworks_> jlmjvm: cool. Is it within your tolerance?
[14:18:04] <skunkworks_> (can you live with it?) Do you have some time differences between the 2 runs?
[14:19:08] <jlmjvm> just checking on sim now,but the diff is visible on the vel
[14:19:34] <jlmjvm> .005 should be cool on most stuff
[14:25:06] <jlmjvm> thanks
[14:26:17] <jlmjvm> do you remember who made that small trunion table that was on youtube?
[14:28:47] <skunkworks_> no
[14:29:36] <jlmjvm> cant find it,used to have the link,but the old computer died
[14:38:16] <fenn> jlmjvm: http://www.hightechsystemsllc.com/i
[14:38:23] <fenn> without the i
[14:41:47] <jlmjvm> thanks fenn
[14:50:32] <skunkworks_> http://youtube.com/watch?v=w0-tXDEvAqg
[14:53:57] <fenn> they should rotate the rotary table 90 degrees so the stepper doesn't bang into the xy table
[14:56:42] <archivist> and tie the cable up, it wont last long like that
[15:02:56] <alex_joni> archivist: how much for such a clock?
[15:03:26] <archivist> we were just wondering here as well
[15:03:40] <alex_joni> couple grand ?
[15:04:14] <alex_joni> sure looks great
[15:05:07] <alex_joni> bbl
[15:11:54] <ALS> is there a way to make the live cd install without booting from cd?
[15:14:49] <cradek> ALS: I don't think so
[15:17:04] <ALS> i only have 128meg of ram and 8 shared vidio, on my dell I got it to install with that amount but this comaq,no luck
[15:17:35] <cradek> I doubt you can run the full ubuntu environment happily without more ram, even if you manage to get it installed
[15:42:38] <JymmmEMC> ALS: You want to boot from something else, but install the liveCd?
[15:43:50] <JymmmEMC> There's always GUI-less install, but like cradek mentioned, 128MB isn't very much.
[15:44:16] <JymmmEMC> ALS: Is this a new board? are there more slots to add more ram?
[15:48:10] <ALS> old 533mgz it runs w2k just but would like to get ubuntu on it
[15:49:16] <JymmmEMC> what are the ram specs/capacity?
[15:50:22] <ALS> tring to find that out now
[15:50:30] <ALS> maybe 512
[15:50:39] <cradek> probably PC133
[15:50:42] <cradek> yeah maybe up to 512
[15:51:04] <ALS> yes dimm sdram
[15:52:18] <cradek> ALS: check craigslist for your city... I got some ram recently for $15/GB
[15:53:04] <BigJohnT> There is a link somewhere for cutting the end of a ball screw but I can't find it. Anyone remember it... It had a neat way to hold the ball screw in the lathe for cutting and centering...
[15:54:02] <JymmmEMC> BigJohnT: http://sillyputty+crazyglue+ducttapeballscrewholder.com/ ;)
[15:54:42] <BigJohnT> JymmmEMC: the link is broken :(
[15:57:35] <cradek> BigJohnT: is there enough space past the threads for a steady rest to hold it? (and is your lathe long enough?)
[15:59:13] <BigJohnT> My lathe is 42" long but I don't have a steady rest :(
[15:59:30] <cradek> no time like the present to make one!
[15:59:39] <BigJohnT> YEP!
[15:59:52] <BigJohnT> this is a very short screw about 9" long
[15:59:55] <cradek> unless you can run it between centers I don't see much choice
[16:00:04] <ALS> will not go through the hole?
[16:00:10] <cradek> oh, that helps, I was picturing 36"
[16:00:42] <BigJohnT> I'm just wondering how to hold it without marring the threads and how to indicate it in the chuck
[16:00:53] <BigJohnT> 4 jaw chuck
[16:01:11] <BigJohnT> 1/2-10 acme screw actually
[16:01:32] <skunkworks_> how to center it? slip fitting sleave over the leadscrew?
[16:01:34] <cradek> bore a long soft collet that fits the OD?
[16:01:45] <cradek> yeah sleeve = collet
[16:02:06] <BigJohnT> I have 5-C collet chuck ... slap on forhead
[16:02:14] <skunkworks_> heh
[16:02:18] <cradek> haha
[16:02:22] <ALS> set your lead screw to the pitch of the thread
[16:02:26] <archivist> and a separate concentric one for indicating and set up if needed
[16:02:27] <BigJohnT> never too early to start drinking I guess
[16:02:43] <BigJohnT> ALS: Cool
[16:02:45] <cradek> good idea, you can run the indicator in the thread then
[16:03:09] <cradek> we're so smart (but only collectively)
[16:03:22] <ALS> hehe
[16:03:26] <SkinnYPuppY> Use some brass or aluminum strips as temporary softjaws and a bushing that will just slip over it to dial in the t.i.r.
[16:04:37] <BigJohnT> I could make an aluminum collet real fast and use the 4 jaw to get it to 0.0001 run out using the patented ALS: indicator method...
[16:05:39] <cradek> is there a hole for a center on either end?
[16:06:46] <BigJohnT> cradek: as long as the collective doesn't start assimilating people were ok
[16:06:58] <BigJohnT> cradek: no center holes at this time
[16:08:25] <BigJohnT> I have to turn down 1 3/4" for the bearings, nut, and connector so I'll indicate the end and put a center in it first
[16:09:09] <ALS> if you center drill them finish bore the center drill hole
[16:09:38] <BigJohnT> ALS: I don't follow
[16:10:11] <ALS> many times the drill will get pushed off a little
[16:11:11] <BigJohnT> This is a 1/2, don't know if I have a tool as small as that to bore...
[16:11:15] <ALS> you can indicate the center drilled part and if its good move on
[16:11:29] <BigJohnT> ok, that I can do
[16:12:24] <BigJohnT> good thing is I have 36" so I can practice on one and if I get some experiance instead of what I expected I can learn from that LOL
[16:12:24] <ALS> hss ground to 29 deg point ,compound set to 60degs
[16:12:28] <cradek> gene: it's silly to ask for help with commercial software on the emc list!
[16:13:01] <BigJohnT> ok
[16:14:01] <JymmmEMC> ALS: If you get the details on the ram, I might have available. But I'd rather it not just be a guess at the specs.
[16:14:29] <JymmmEMC> compaq can be funkyish
[16:14:46] <ALS> sdram dimm 100 or 133mz
[16:15:31] <JymmmEMC> ecc? nonecc? registered? max capacity? pairs?
[16:16:26] <JymmmEMC> ALS: look it up here if you can: http://www.oempcworld.com/
[16:19:21] <ALS> 64 MB 100 MHz SyncDRAM, shared memory architeture, two total DIMM slots, upgradable to 512 MB - 8 MB dedicated for video memory (SyncDRAM DIMM required)
[16:19:46] <ALS> from compaq
[16:21:03] <JymmmEMC> so probably 2x256sdram 100MHz
[16:21:31] <ALS> ya
[16:21:41] <JymmmEMC> ALS: Wait....on board video? Are you sure you want to use that system for emc?
[16:22:00] <ALS> yes/no
[16:22:08] <JymmmEMC> it be better to use an older system with no onboard video, even if you plan on using an ext video card.
[16:22:34] <archivist> some comaq on board still have a video system with separate ram
[16:22:53] <archivist> probably will be ok
[16:23:42] <archivist> if using system ram then not so good/baaad
[16:23:45] <SWPadnos> if it says "8MB Dedicated for video", then it's just about guaranteed to be shared RAM
[16:24:01] <JymmmEMC> archivist: his is shared video ram, so that be a bad thing, but even if he uses an ext video card, that onboard is still visable to the system and just one more thing to have to deal with.
[16:24:19] <ALS> I don't relly plan on running a cnc with this machine just play time and have linux for learning and dev.
[16:25:07] <JymmmEMC> ALS: Well, shit... do you have $600?
[16:25:07] <fenn> BigJohnT: to accurately hold a ballscrew you can make a sleeve that press fits over the balls as they are in the thread groove
[16:25:30] <ALS> whay for?
[16:25:36] <ALS> what
[16:25:42] <fenn> or if you use a drive pin you can use slip fit
[16:26:02] <fenn> the crests of the threads are not necessarily centered wrt the pitch diameter
[16:26:07] <JymmmEMC> ALS: http://www.dell.com/content/topics/segtopic.aspx/linux_3x?c=us&cs=19&l=en&s=dhs
[16:27:01] <ALS> I have a dell running EMC2
[16:27:48] <BigJohnT> fenn: it's actually an acme screw
[16:29:34] <fenn> just wrap some aluminum shims around the chuck jaws then
[16:30:17] <SWPadnos> JymmmEMC, note that those dells have no parallel port ...
[16:30:31] <ALS> booo
[16:31:06] <SWPadnos> they do have PCI slots though, so a Mesa card would sork :)
[16:31:10] <SWPadnos> or work, even
[16:31:14] <JymmmEMC> SWPadnos: he said he want to play with linux, not cnc
[16:31:26] <SWPadnos> then there's no problem with onboard video
[16:31:40] <SWPadnos> that's only an issue when you actually want to control stepper machines
[16:31:42] <JymmmEMC> for $600 he can have a nice lil nix laptop
[16:32:05] <SWPadnos> it isn't likely to be a problem with servos (or any other config that doesn't need a really fast BASE_PERIOD)
[16:32:07] <JymmmEMC> with 1GB of ram even =)
[16:32:29] <JymmmEMC> hey, what about a pcmcia paraport? anyone ever tried that?
[16:32:53] <SWPadnos> yes, they work once you figure out the base address
[16:32:56] <JymmmEMC> usually they perform much better than onboard ones in a alaptop
[16:33:05] <JymmmEMC> 0xd400 =)
[16:33:13] <JymmmEMC> or...
[16:33:16] <JymmmEMC> DEBUG
[16:33:20] <JymmmEMC> D 04:00
[16:33:22] <JymmmEMC> =)
[16:38:30] <JymmmEMC> LOL http://www.craigslist.org/about/best/hou/590888944.html
[16:39:16] <bill20r3> classy!
[16:40:10] <SkinnYPuppY> OMG
[16:41:56] <BigJohnT> that's some pair
[16:42:08] <ALS> mom pam and two on the way + rims
[17:01:35] <JymmmEMC> And the pregnant girl is looking for a boyfriend
[17:01:48] <SWPadnos> or a girlfriend
[17:02:02] <SWPadnos> (she didn't say :) )
[17:02:02] <JymmmEMC> Nah, that's what Mom is for
[17:02:10] <archivist> gf plus free mother
[17:02:10] <BigJohnT> don't forget the pony
[17:02:20] <SWPadnos> no - apparently that cuases friction in their mother-daughter relationship
[17:02:30] <JymmmEMC> dont forget that mom puts out too
[17:02:47] <SWPadnos> yeah, a two-fer for the boyufriend, but it's short-term
[17:02:50] <SkinnYPuppY> Look @ the date, must have been a heck of a valentines
[17:02:52] <SWPadnos> -u
[17:03:23] <SWPadnos> OMG ponies!!!
[17:04:38] <JymmmEMC> and DOUBLE child support.... the DA is gonna have a field day with this one, not to mention the one child will be the aunt/uncle to the other one.
[17:05:18] <ALS> step children ,neice,and sister
[17:05:22] <archivist> or half brother/sister
[17:05:23] <BigJohnT> * BigJohnT humms I am my own Grandpa by the muppets
[17:06:23] <skunkworks_> * skunkworks_ tries not to think about it
[17:06:57] <alex_joni> SkinnYPuppY: too soon after valentine
[17:07:44] <archivist> I used to know a bloke having fun mother and daughter
[17:09:47] <alex_joni> archivist: tmi
[17:10:11] <archivist> tmi?
[17:10:19] <skunkworks_> heh - ran the latency-test all night 8us
[17:10:19] <alex_joni> giyf :)
[17:10:28] <alex_joni> skunkworks_: dual-proc?
[17:10:40] <skunkworks_> no 1ghz old compaz.
[17:10:43] <skunkworks_> compaq
[17:10:45] <alex_joni> sounds great
[17:10:55] <skunkworks_> yes - should work grreat
[17:11:37] <archivist> hmm what model, compaq's seem common over here as well
[17:15:48] <lewin1> lewin1 is now known as lewing
[17:16:24] <skunkworks_> deskpro ec
[17:16:26] <skunkworks_> en
[17:16:36] <skunkworks_> those really small cases
[17:16:43] <SkinnYPuppY> Intel cpu ?
[17:18:38] <skunkworks_> yes
[17:18:46] <skunkworks_> case looks similar to this http://www.electronicsam.com/images/866mhz.JPG
[17:19:13] <skunkworks_> (same style - this one worked good also but required a external video card as this one had shared memory)
[17:20:12] <skunkworks_> actually was doing this http://www.electronicsam.com/images/866mhzyum.JPG
[17:21:30] <skunkworks_> 40khz step rate
[17:22:22] <skunkworks_> The 1ghz machine doesn't have shared video memory. The onboard is working great
[17:22:46] <JymmmEMC> http://www.malevole.com/mv/misc/killerquiz/
[17:23:01] <JymmmEMC> I got 5/10
[17:23:51] <archivist> I got you need flash to play this game
[17:24:16] <JymmmEMC> Works fine in ubuntu for me
[17:24:54] <archivist> Im on an old debian box
[17:25:02] <skunkworks_> they look like this http://cgi.ebay.com/2-COMPAQ-DESKPRO-EN-SFF-COMPUTER-PD1060-USED-TESTED_W0QQitemZ380002892977QQihZ025QQcategoryZ140072QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
[17:25:43] <JymmmEMC> archivist: ah
[17:26:02] <SWPadnos> that figures. I missed the one I should have gotten right - 9/10
[17:26:10] <SWPadnos> (missed "son of sam"
[17:26:12] <SWPadnos> )
[17:27:17] <skunkworks_> what?
[17:27:23] <skunkworks_> * skunkworks_ is a son of sam ;)
[17:27:24] <SWPadnos> different sam :)
[17:27:30] <SWPadnos> and different son
[17:27:40] <SkinnYPuppY> sos
[17:27:55] <SWPadnos> http://en.wikipedia.org/wiki/David_Berkowitz
[17:29:37] <archivist> weeeeee on my winbox 10/10
[17:37:56] <lerman> Have you ever programmed in SNOBOL? Inventing it is worse than being a serial killer. :-)
[17:38:04] <archivist> hehe
[17:38:41] <SWPadnos> isn't that the Satanic version of COBOL? (Satanic New Order Business Operating Language) :)
[18:15:18] <skunkworks_> fenn has some problems today..
[18:17:57] <ALS> bbl
[18:30:46] <fenn_> apparently moving the cordless phone to a new location makes the DSL modem freak out
[18:39:20] <skunkworks_> interesting. My cell phone gets into my speakers.. When my cell phone is about to ring - the speakers go SHRITS..
[18:52:15] <JymmmEMC> dee da, dee da, de de de de de de de
[18:56:36] <BigJohnT> one lead screw done, thanks for the tips
[18:57:02] <BigJohnT> wish I had my camera here
[18:58:49] <BigJohnT> bbl
[20:03:15] <BigJohnT> http://i47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/HPIM0624.jpg
[20:03:30] <BigJohnT> crappy picture but it's done'
[20:38:42] <skunkworks_> cool
[20:39:55] <cradek> looks nice
[21:03:10] <alex_joni> hi guys
[21:03:34] <BigJohnT> thanks
[21:03:43] <alex_joni> BigJohnT: nice work
[21:03:53] <alex_joni> looks absolutely spot on..
[21:04:00] <alex_joni> err.. what's it supposed to do?
[21:04:08] <BigJohnT> it'
[21:04:18] <BigJohnT> it's the Z axis lead screw
[21:04:32] <fenn_> where was the raw material from?
[21:04:43] <BigJohnT> mcmaster carr
[21:05:40] <BigJohnT> two bearings go on in the bearing block then a threaded shaft collar then the coupling
[21:07:40] <BigJohnT> http://i47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/zassb.jpg
[21:08:03] <BigJohnT> motor mount missing from that picture
[21:08:56] <fenn_> so you tapped the plate that goes on the end of the 80/20?
[21:09:01] <fenn_> fenn_ is now known as fenn
[21:09:45] <BigJohnT> fenn: no there is a brass nut under that plate
[21:09:51] <fenn> ok
[21:10:24] <BigJohnT> two small screws hold the nut up
[21:12:05] <fenn> a polyurethane topcoat over regular paint is the greatest thing since sliced bread
[21:26:10] <BigJohnT> BTW, fenn: that is frameworld not 80/20 it's more cost effective
[21:33:00] <tomp2> wow frameworld is about 10 minutes from my place
[21:35:38] <BigJohnT> cool
[21:39:46] <BigJohnT> the muppets are singing I am my own Grandpa on my computer as I type
[22:11:06] <BigJohnT> * BigJohnT is off to the house, might make some sparks tomorrow...
[22:21:54] <acemi_> acemi_ is now known as acemi
[22:23:55] <alex_joni> night all
[22:24:24] <skunkworks_> night alex
