#emc | Logs for 2008-09-05

[00:00:23] <dareposte> dmesg doesn't show anything too terrible to my untrained eye either
[00:00:51] <dareposte> loads a bunch of RTAI modules, then unloads them
[00:21:48] <dareposte> It loaded!
[00:22:07] <dareposte> it will now load most of the interfaces except for AXIS interface
[00:22:11] <dareposte> then it crashes
[00:22:16] <dareposte> anybody?
[00:25:19] <dmess> dont use AXIS...
[00:26:33] <dareposte> but its sooo purdy
[00:28:00] <dareposte> guess i don't have a choice
[00:28:17] <dareposte> any recommendations for non-axis interfaces? I haven't messed with the others much yet
[00:32:30] <SWPadnos> AXIs is the only UI that uses openGL
[00:32:41] <SWPadnos> check that you have working openGL - run glxgears in a terminal
[00:48:00] <yatesdr_> cool it works!
[00:48:11] <SWPadnos> yay
[00:50:14] <dareposte1> cool it works!
[00:50:41] <dareposte1> it turned out to be a problem with building against tcl/tk 8.5 instead of 8.4
[00:50:59] <SWPadnos> heh - oops :)
[00:51:42] <SWPadnos> that makes some sense - AXIS uses tcl/tk (as does tkemc), but it uses it with external libraries, whereas tkemc doesn't
[00:53:09] <dareposte1> used "./configure --enable-run-in-place --with-tclConfig=/usr/lib/tcl8.4/tclConfig.sh --with-tkConfig=/usr/lib/tk8.4/tkConfig.sh"
[00:53:34] <dareposte1> also linked against newer glut libraries which may or may not have had anything to do with it?
[00:53:45] <dareposte1> instead of using freeglut used regular glut
[00:53:59] <dareposte1> at any rate i'm one happy camper now
[00:54:22] <dareposte1> except i lost my configuration files in the shuffle so I guess i have to remake those
[00:55:22] <dareposte1> SWPadnos: I think you are on to something, because all the curses based UI's worked fine, just not the graphical ones
[00:55:26] <SWPadnos> heh - should be pretty easy with stepconf
[00:55:37] <SWPadnos> oh, did tkemc also not work?
[00:55:41] <dareposte1> dareposte1 is now known as dareposte
[00:56:00] <dareposte> don't remember, but i doubt it
[00:56:20] <SWPadnos> ok. even if it did, it would still make sense to me (maybe not the the real experts though)
[00:56:23] <dareposte> i just went through and clicked randomly on different ones, and all the ones that loaded were text-mode curses based
[00:56:59] <SWPadnos> AXIS uses some tcl/tk for the UI, but also links with python and C code, so there's a level of complexity there that tkemc doesn't have (as far as I know)
[00:57:04] <SWPadnos> ah
[00:57:08] <dareposte> ooh good point
[00:57:16] <dareposte> i did install some python tk bindings too
[00:57:23] <dareposte> well heck now i don't have a clue what actually fixed it
[00:57:37] <SWPadnos> glad you got it working. gotta get back to accounting now :)
[00:57:39] <dareposte> shotgun approach
[00:57:45] <dareposte> thanks for your help
[00:57:53] <SWPadnos> you're welcome
[00:57:58] <dareposte> what time zone are you in to be accounting at this hour??
[00:58:04] <SWPadnos> eastern
[00:58:10] <SWPadnos> but I own the business so ...
[00:58:12] <dareposte> oh
[00:58:25] <dareposte> congratulations
[00:58:32] <SWPadnos> still got 3 more work hours today ;)
[00:58:48] <dareposte> at least you own it though :)(
[00:59:19] <dareposte> thanks again!
[01:25:16] <JymmmEMC> SWPadnos: Get your ass back to work!
[01:32:42] <stustev> SWPadnos: let the monkey do the accounting
[01:34:03] <SWPadnos> stustev, the monkeys at the IRS don't like that
[01:35:06] <antichip> how is everyone tonight?
[01:35:45] <stustev> the IRS doesn't have monkeys - just apes
[01:51:57] <antichip> I am thinking of using R/C type speed controllers and smallish dc motors with a linear encoder for a makeshift servo set-up
[02:05:55] <jmkasunich> cradek: what kind of drills do you use for PCBs? straight shank (and some kind of chuck) or 1/8" shank and a collet?
[02:11:38] <cradek> 1/8 shank and 1/8 set screw holders
[02:11:56] <cradek> I doubt any drill chuck would work acceptably
[02:13:59] <jmkasunich> yeah, probalby too much runout
[02:14:20] <jmkasunich> I was wondering if I should make an adapter to put one of these http://www.amazon.com/Keyless-Chuck/dp/B0009V68X8/ref=cm_cr_pr_sims_t/002-5555198-3484045 on the bosch
[02:14:35] <jmkasunich> all it needs is a male thread
[03:22:55] <JymmmEMC> jmkasunich: I have one like it, uses 1/4-20 thread
[03:23:26] <JymmmEMC> jmkasunich: Yes, made in china, yes from HF, really ironic that it uses imperial threads
[03:24:15] <JymmmEMC> It's a three-piece jaw, spring loaded.
[03:25:44] <JymmmEMC> as you screw it on the bolt, it pushes down on a flat metal plate, which closes the jaws.
[03:29:44] <KimK> Any news on the m5i21 driver? I see the recently released EMC2_Integrator_Manual.pdf dated September 1, 2008 mentions only the m5i20.
[04:06:50] <cradek> jmkasunich: I bet a $5 drill chuck is worth every penny
[04:12:06] <stustev> and not much more
[04:12:20] <cradek> that was fun. I made a nice little boring bar (probably two hours of grinding)
[04:12:30] <stustev> by hand?
[04:12:35] <cradek> then a bushing to hold it (.25) in a boring bar holder (.625)
[04:12:36] <cradek> yes
[04:12:47] <stustev> HSS?
[04:12:50] <cradek> yes
[04:13:04] <stustev> have you tried it yet?
[04:13:26] <cradek> I blindly turned 1" down to .625" with whatever tool offsets I had from last time and I got .6246
[04:13:40] <stustev> sweet
[04:13:46] <cradek> then I drilled and reamed the center and pushed the boring bar in and it sprang back out
[04:13:59] <cradek> ... seems it's a real lathe
[04:14:05] <stustev> from the air pressure?
[04:14:10] <cradek> yes
[04:14:17] <stustev> nice fit
[04:14:31] <stustev> round hole
[04:14:36] <cradek> it didn't matter because I will slot it anyway, but it's nice to have stuff turn out right.
[04:15:09] <stustev> I can feel your confidence rising with that lathe
[04:15:29] <cradek> also, emc is cool.
[04:15:48] <stustev> I will NOT disagree with that
[04:18:02] <stustev> just passing thru on my way to bed - good night
[04:18:09] <cradek> me too. goodnight.
[06:51:55] <Lerman_> Lerman_ is now known as Lerman
[08:28:47] <Assargadon_> Assargadon_ is now known as Assargadon
[09:01:12] <Lerman_> Lerman_ is now known as Lerman
[11:40:00] <Assargadon_> Assargadon_ is now known as Assargadon
[16:16:47] <stuste1> good day earth
[16:19:49] <cradek> wow, anyone in CA need a plate? http://losangeles.craigslist.org/lac/tls/822894415.html
[16:19:52] <cradek> hi stuart
[16:22:01] <JymmmEMC> oh man, this is SO much better! Gotta love 5ft pwr strips!
[16:23:33] <JymmmEMC> that be nice to have. is pink higher density?
[16:24:26] <cradek> I think it's supposed to wear less
[16:24:32] <JymmmEMC> ah
[16:24:37] <anonimasu__> logger_emc: bookmark
[16:24:37] <anonimasu__> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-09-05.txt
[16:24:49] <cradek> starrett pinks are NOT cheap
[16:25:11] <JymmmEMC> I really dont have any place for it, even if I was in SoCal
[16:25:21] <JymmmEMC> except the back yard - ick
[16:25:25] <anonimasu__> hm..
[16:25:28] <jepler> I wonder if that's anywhere near dave-e
[16:25:29] <cradek> ha
[16:25:31] <anonimasu__> I could use that one as diing table.
[16:25:33] <anonimasu__> dining
[16:25:43] <anonimasu__> just because it's pretty ^_^
[16:25:58] <cradek> it'd make a great cutting board for the kitchen
[16:25:59] <JymmmEMC> anonimasu__: Awww isn;t that precious
[16:26:58] <anonimasu__> :)
[16:27:03] <JymmmEMC> cradek: I'm not using $400 knives on a granet anything tyvm!
[17:07:32] <archivist_ub> you could use the table to hone your knives
[17:27:31] <JymmmEMC> that's true, but do you really want honing oil on such a nice table?
[17:47:09] <SkullWorks_PGAB> I received my shipping confirmation on 6 Gecko G251 drives at the Promo price of $37 ea. - Last chance to get yours, price expires Sept 6.
[17:53:04] <anonimasu__> anonimasu__ is now known as anonimasu
[17:53:56] <Jymm> nice SkullWorks_PGAB
[18:01:51] <SkullWorks_PGAB> yeah normal price will be like $69 ea. - I don't even have any idea what I will use them on yet, but I needed 3 for a shopmaster conversion I'm doing for a friend, so I had him get 6 and I got six, means I'll have 9 on the shelf.
[18:02:53] <SkullWorks_PGAB> Oh - They had a limit of 6 per person at the sale price.
[18:38:24] <assargadon> hm
[18:38:45] <assargadon> it looks like my soundcard is not working in realtime environment
[18:39:22] <jepler> assargadon: it may work if you install the package linux-ubuntu-modules-2.6.24-16-rtai and reboot
[18:40:06] <assargadon> hm...thanks, let's try it
[19:13:53] <dmess> any one know how to get to the bios on an acer laptop
[19:14:41] <SWPadnos> it's probably ESC, F2, DEL, INS, CTRL-F2, or S
[19:14:54] <SWPadnos> of course, it could also be something else
[19:14:58] <dmess> oh yeah without a working keyboard on board
[19:15:16] <anonimasu> plug another one in..
[19:15:16] <SWPadnos> replace the keyboard, or plug in an external one
[19:15:28] <anonimasu> if that dosent work.. then you are fscked..
[19:16:06] <dmess> ok ill try some of those... but i dunno if the bios sees the usb keyboard yet or if i have to set it up
[19:16:24] <SWPadnos> the web seems to think it's F2 on the Acers (and many other laptops)
[19:16:44] <SWPadnos> if legacy support is on, then it will. if legacy support is off, then it might
[19:16:52] <SWPadnos> is there no PS/2 port?
[19:17:14] <dmess> f2 gets me to the winblows recovery but NOne of the arrow keys work anywhere
[19:17:26] <dmess> no.. retards..
[19:17:34] <SWPadnos> you're hitting the keys too slowly
[19:17:49] <dmess> ill try again
[19:17:58] <SWPadnos> if it gets to the Windows boot menu, then it's already well past the time for going to BIOS setup
[19:18:12] <dmess> i know
[19:18:23] <SWPadnos> what I usually do is repeatedly tap the key I'm trying as soon as I power on the machine
[19:18:53] <SWPadnos> you never know how fast the keyboard gets reset, or how little time the BIOS will look for the magic key
[19:19:44] <dmess> do you think a usb kbd would need bios setting
[19:20:00] <SWPadnos> for a laptop with no PS/2 port, it's worth a shot to try one
[19:20:21] <SWPadnos> unless USB legacy support has been specifically disabled (and maybe even then), a USB keyboard should work for the BIOS
[19:22:13] <archivist_ub> just fix the internal keyboard
[19:25:02] <tomp> any recommendations for rolled ballscrew vendors?
[19:25:14] <jepler> just make an avr microcontroller project that hooks into the keyboard connector and emulates the F2 keypress
[19:25:36] <jepler> time permitted: 25 minutes
[19:28:09] <SkullWorks_PGAB> tomp - Nook XPR
[19:28:57] <tomp> SkullWorks_PGAB: thanks, know any published price lists?
[19:30:06] <SWPadnos> how about checking mcmaster-carr or MSC?
[19:30:38] <SkullWorks_PGAB> no - but Nook XPR has best specs for rolled max error .001" per foot
[19:30:54] <SkullWorks_PGAB> Thompson is .004"
[19:31:21] <tomp> SkullWorks_PGAB: i saw the .001 :) , thanks
[19:31:24] <SkullWorks_PGAB> and there prices and customer support are great
[19:31:44] <SkullWorks_PGAB> we use them at work for all sorts of things
[19:52:19] <dmess> sure Jep.. im off to the holo-deck to replicate that
[22:14:05] <JymmmEMC> SWPadnos: http://www.arduino.cc/
[23:23:35] <andypugh> Hi. Anyone paying attention?
[23:24:38] <andypugh> I am having installation issues. Well, the LiveCD works, but latency is unimpressive and it only uses one of my two CPUS
[23:25:21] <andypugh> So I have been trying to build from scratch with SMP support, with almost no success.
[23:32:08] <SkullWorks_PGAB> some users have made SMP work - I don't know the details, but its been tried and it worked - though it might have been with v2.1
[23:32:25] <jmkasunich> its not the EMC version that matters
[23:32:40] <jmkasunich> building an SMP kernel with RT patches is the hard part
[23:32:55] <andypugh> Aye, I haven't got as far as getting RTAI to work.
[23:33:29] <andypugh> I think that it is in the config options, which are truly baffling to a long-term Mac user.
[23:33:43] <jmkasunich> I can't help - haven't built one myself
[23:33:44] <SkullWorks_PGAB> think it was the Breezy kernal
[23:33:44] <andypugh> I really want to be cutting metal, not building an OS...
[23:34:07] <jmkasunich> cradek did build an experimental SMP/RTAI kernel that seemed to work on some systems
[23:34:25] <jmkasunich> I don't recall where he put it, but I think its online somehwhere
[23:35:54] <andypugh> I may be able to work with the LiveCD install, and just accept the wasted CPU, but the latency tests run at 15uS (acceptable) with occasional 4000uS glitches (clearly not)
[23:36:20] <jmkasunich> its unlikely that SMP would help that
[23:36:39] <jmkasunich> have you looked at the troubleshooting page on the wiki - it talks about some latency killers and possible workarounds
[23:36:42] <andypugh> I am really looking for a better match to my hardware.
[23:37:19] <andypugh> It all seems a bit vague, the Wiki stuff, unless I am looking on the wrong bit.
[23:37:49] <andypugh> I am borrowing a graphics card over the weekend, I will try that.
[23:38:35] <andypugh> But the onboard is a fairly decent ATI chipset with its own memory, so is probably not the cause.
[23:38:54] <jmkasunich> this is the page: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting
[23:39:23] <jmkasunich> if your bad latency events happen at regular 64 second intervals, that points to SMI
[23:42:05] <andypugh> I was just looking at that, it certainly looks like it is worth a try.
[23:42:28] <andypugh> As it is an Intel motherboard.
[23:43:48] <andypugh> As I said, this is all new to me, since 1988 I have just bought Apple stuff, which has Just Worked.
[23:44:42] <andypugh> (Though I have picked up a lot of geek-stuff by osmosis, and I write a fair bit of software)
[23:49:45] <andypugh> OK, I am booting off the live CD to see if the glitches are periodic.
[23:50:20] <andypugh> The fix looks vaguely painful, though. ie a recompile.
[23:55:18] <andypugh> OK, it is exactly every 64 seconds. Huge thanks.
