#emc | Logs for 2010-10-25

[00:04:00] <theorb> theorb is now known as theorbtwo
[01:31:57] <ries_> ries_ is now known as ries
[03:57:55] <jthornton_> jthornton_ is now known as jthornton
[06:43:36] <mrsunshine> hmm, do i need to set a variable in the mill config to set the tool change position ?
[07:07:43] <mrsunshine> hows a hall switch to use as limiting/home switches?
[07:07:45] <mrsunshine> good bad?
[07:08:09] <mrsunshine> will only mill non magnetic materials
[07:23:31] <nullie> it's probably not as precise as mechanical switch
[07:43:37] <alex_joni> depends how fast you move
[07:43:44] <alex_joni> as a limit switch it's surely fine
[07:43:56] <alex_joni> as a home switch it's probably fine, if you have a pretty slow latch speed
[12:10:44] <Jymmm> JT-Hardinge: ping
[12:30:48] <jepler> anyone want to double-check my fix for SF#3092250 (near doesn't work for negative numbers and relative difference) http://emergent.unpy.net/files/sandbox/near.patches.mbox
[12:42:29] <MattyMatt> perfect emc2 pc? http://robosavvy.com/store/product_info.php/cPath/39/products_id/521
[12:44:04] <alex_joni> MattyMatt: not really
[12:46:43] <Jymmm> Ok, a servo motor + encoder, attached to a belt driven reducer then output shaft.... Why would you have a optical interrupter on the output shaft in this configuration
[12:47:58] <Jymmm> By belt, I mean fancy rubber band - friction
[12:48:19] <Jymmm> (meant to rotate glass)
[12:48:55] <MattyMatt> syncing for tapping etc?
[12:49:00] <Jymmm> Here is a video... http://www.dongares.com/rotary_mpeg4.avi
[12:49:27] <MattyMatt> or maybe just for the RPM DRO
[12:50:05] <Jymmm> Never seen someone tap glass before
[12:51:53] <SWPadnos> rubber band breakage sensor?
[12:52:21] <Jymmm> SWPadnos: Any other purpose it might serve?
[12:52:41] <SWPadnos> dunno, the video is unwatchable on this PC
[12:52:53] <Jymmm> SWPadnos: Ah, try VLC ?
[12:53:08] <SWPadnos> I was using RealPlayer something.or.other
[12:53:24] <Jymmm> Yeah, try VLC if you can
[12:54:22] <alex_joni> Jymmm: a belt can slip
[12:54:33] <Jymmm> alex_joni: ok
[12:54:39] <alex_joni> and cause misalignment because of thermal influences
[12:54:46] <Jymmm> heh
[12:59:42] <Jymmm> Anyone have any ideas on what could be the cause in that video? It shouldn't be turning at all during initial power on,
[13:06:19] <alex_joni> Jymmm: to be able to guess, I'd have to know how it's connected and commanded
[13:07:18] <Jymmm> alex_joni: It should be stationary. It's at the power on stage.
[13:07:42] <alex_joni> Jymmm: it should hold position != it should be stationary
[13:08:28] <Jymmm> alex_joni: Ok, you win. So if it's trying to find "home",
[13:08:39] <SWPadnos> or not powered ...
[13:08:59] <Jymmm> SWPadnos: What's not powered? The motor is at least
[13:09:29] <SWPadnos> the driver may be, but the motor may not be. Or homing as you said ...
[13:09:51] <Jymmm> SWPadnos: you seen the video?
[13:09:57] <SWPadnos> nope :)
[13:10:28] <SWPadnos> well, parts of it, between full-screen green flickers
[13:10:37] <SWPadnos> made it hard to tell what was happening
[13:10:55] <Jymmm> install VLC, it cna play everything.
[13:11:12] <SWPadnos> I think I'll leave this Win2K machine as is for now
[13:11:37] <Jymmm> Install VLC portable then, delete the folder == uninstalled
[13:12:08] <Jymmm> can even be run from a thumbstick
[13:12:20] <Jymmm> I'll get you the link in a moment
[13:12:49] <SWPadnos> don't waste your time. I've got other things to do anyway
[13:13:57] <Jymmm> SWPadnos: http://v7.tinypic.com/player.swf?file=rib090
[13:14:21] <Jymmm> can you play that video link?
[13:15:23] <SWPadnos> yep, thanks
[13:15:55] <mungkie> i bet its a bad ground connection
[13:17:19] <Jymmm> SWPadnos: http://portableapps.com/apps/music_video/vlc_portable
[13:17:25] <SWPadnos> yeah, it looks (and sounds) like it's not working right
[13:17:43] <SWPadnos> the buy says something like "it should slow down now. Oh look, it took off again"
[13:17:47] <SWPadnos> s/buy/guy/
[13:18:25] <Jymmm> But speculating, is it mechanical, electrical, both?
[13:18:48] <SWPadnos> electrical or optical, I think
[13:18:55] <SWPadnos> the motor seems to move the doodad correctly
[13:19:13] <Jymmm> The nippleless boob =)
[13:19:14] <mungkie> i think a loose wire
[13:19:41] <SWPadnos> that was one ugly boob
[13:19:43] <SWPadnos> IMO
[13:19:47] <Jymmm> LOL
[13:19:51] <mungkie> is it a milking machine?
[13:19:56] <Jymmm> mine too
[13:19:59] <SWPadnos> hard to tell
[13:20:13] <mungkie> it wont be able to milk if there is no nipple
[13:20:25] <Jymmm> mungkie: rotary attachment for a laser engraver; to engrave glasses and bottles, etc
[13:22:33] <Jymmm> SWPadnos: The link I gave installs/writes to NOTHING to the system, all configuration (registry libs etc) are all contained in the folder you install to (which is really just a self extracting archive). You delete the folder, you've uninstalled it.
[13:22:58] <SWPadnos> ok, that's cool
[13:23:58] <Jymmm> SWPadnos: All the portable apps on that site are like that.
[13:24:10] <SWPadnos> yep, seen that before
[13:24:23] <SWPadnos> it's a great resource
[13:24:26] <Jymmm> SWPadnos: You can install them to a thumbstick and take them with you
[13:25:28] <SWPadnos> if only they had "fat binaries", so you could have a thumb drive that could be plugged into a Windows, Linux, and maybe Mac machine to run your programs
[13:26:06] <Jymmm> Or just install knoppix to a thumbstick =)
[13:26:20] <Jymmm> fits on a 1gb stick btw
[13:26:28] <Jymmm> with room to save data
[13:26:47] <Jymmm> then just boot from the stick
[13:27:25] <Jymmm> But use a 2GB stick in case you need to DL and burn ISO's
[13:42:53] <Jymmm> JT-Work: ping
[13:43:08] <JT-Work> hi, Jymmm I didn't get very far yesterday
[13:43:34] <Jymmm> JT-Work: where did you get stuck at?
[13:44:15] <JT-Work> vmc won't run the disk, 386 you know, second computer floppy does not work for some reason, third computer tied up and could not shut it down to boot
[13:44:53] <JT-Work> I have a floppy drive in my had to install into a computer tonight to try it out
[13:45:25] <JT-Work> and I was running the vmc yesterday some so couldn't shut it down much
[13:45:40] <Jymmm> JT-Work: ah, gotcha.
[13:46:08] <Jymmm> JT-Work: Interested in a 486 to replace it?! LOL
[13:46:15] <Jymmm> DX too
[13:49:52] <JT-Work> it is not a normal motherboard at all
[13:50:24] <Jymmm> ok
[14:14:35] <Jymmm> http://v7.tinypic.com/player.swf?file=bfjnep
[15:32:16] <cpresser> hi, slightly OT-question: I am looking for a chart, displaying the DIN8530 (like this one: http://www.tiefbohren.info/DIN8580-2.gif). only in nice and large
[15:32:36] <cpresser> i want to do a large print for my office, and color the parts I am able to do
[15:33:23] <cpresser> its a german standard, so i am not sure, if even anybody of you knows this classification of manufacturing processe :)
[15:37:23] <alexis_4315> hi
[15:37:35] <alexis_4315> hey guys, check this one:
[15:37:36] <alexis_4315> http://www.youtube.com/watch?v=Cd9yR64jwFo&feature=player_embedded
[15:38:03] <alexis_4315> THIS is the new era
[15:38:13] <alexis_4315> ;)
[15:39:51] <alexis_4315> i remember the same on the old movie 'lost in space' have those
[15:41:05] <alexis_4315> gtg, nice day everyone
[15:41:11] <alexis_4315> :)
[16:52:28] <lilalinux> Why does G41/G42 need an entry move?
[17:00:36] <skinnypup> Because you're changing from non compensated to radius compensated path
[17:04:12] <lilalinux> lets say I have a hole with 6mm diameter
[17:04:28] <lilalinux> and a cutter with 5mm diameter
[17:04:44] <lilalinux> shouldnt it be possible to use that cutter for this hole?
[17:05:37] <SWPadnos> yes
[17:05:59] <lilalinux> but the entry move must be at least 1/2 of the cutter radius
[17:05:59] <SWPadnos> but emc has to move the cutter in a 1mm diameter circle to make that hole
[17:06:36] <SWPadnos> turn on compensation before plunging into the middle of the hole
[17:06:48] <lilalinux> so it's a cam problem, and not an emc problem?
[17:06:51] <SWPadnos> and before the move "above" the center
[17:07:02] <SWPadnos> well, it's a geometry problem
[17:07:03] <lilalinux> i'm using dxf2gcode
[17:07:11] <SWPadnos> if you think it's a problem, that is :)
[17:07:31] <skinnypup> i never had good luck with dxf2gcode
[17:07:42] <skinnypup> try sheetcam
[17:08:54] <atmega> I bought cut2d, it seems to work really well, if you have a winbox
[17:08:57] <skinnypup> you can change the lead in and lead out radius in the gui there
[17:10:01] <atmega> or just get a 6mm cutter or a 5mm hole
[17:10:18] <skinnypup> o_0
[17:11:29] <lilalinux> SWPadnos: so the entry move can be done in the air?
[17:11:41] <SWPadnos> yes, it just haas to have an X/Y component
[17:11:43] <SWPadnos> has
[17:20:01] <lilalinux> will activating G41/G42 afftect Z?
[17:22:50] <SWPadnos> no
[17:24:26] <lilalinux> oky doky
[17:24:28] <lilalinux> we have a winner
[17:24:29] <lilalinux> thank you
[17:24:36] <SWPadnos> sure
[17:27:11] <lepton> Has there been much work on communicating with VFDs via CAN or Ethernet? I'm trying to search through old EMC archives without a lot of success
[17:27:38] <kb8wmc> Axis is locking up the computer on startup, using 10.04 Lucid, EMC2 2.4.5, ATI Rage 128 video, any suggestions for possibly changing video to VESA? Thanks
[17:34:24] <kb8wmc> Axis is locking up the computer on startup, using 10.04 Lucid, EMC2 2.4.5, ATI Rage 128 video, any suggestions for possibly changing video to VESA? Thanks
[17:35:00] <kb8wmc> hello Andy, thanks for posting your suggestions in the forum
[17:37:38] <andypugh> Have you tried creating then editing an xorg.conf? (I confess that might as well be a magical incantation to me as far as what it actually _means_ is concerned)
[17:38:30] <kb8wmc> andypugh: yes, I have, I followed the directions from the link you posted, but from there I am stuck...
[17:40:05] <andypugh> is there a line in xorg.conf that says something like driver=r128 ?
[17:41:16] <kb8wmc> yes, standby and I will copy/paste to here
[17:43:00] <kb8wmc> Identifier "Card0" Driver "r128" VendorName "ATI Technologies Inc" BoardName "Rage 128 Pro Ultra TF" BusID "PCI:1:0:0"
[17:43:22] <psha> replace r128 with vesa
[17:43:26] <psha> in 'Driver' clause
[17:44:06] <kb8wmc> roger that psha, will give it a try...thanks
[17:46:49] <kb8wmc> going to reboot and give it a try now...again tnx for help
[17:59:39] <andypugh> That took worrying long?
[18:00:04] <kb8wmc> well, it didn't like that change to the xorg.conf file
[18:00:36] <andypugh> it was "vesa" not "Vesa"?
[18:00:51] <kb8wmc> my monitor just displayed an "out of frequency" error
[18:01:07] <kb8wmc> correct Andy, all lower case
[18:01:34] <andypugh> Flatscreen monitor?
[18:01:39] <kb8wmc> yes sir
[18:01:55] <andypugh> it might default to 75Hz, which is faster than most flatscreens can handle.
[18:02:04] <kb8wmc> hmmm
[18:06:04] <psha> kb8wmc: you are with r128 now?
[18:06:14] <andypugh> Looks like an entry in Section Monitor (VertRefresh) might help. http://linux.die.net/man/5/xorg.conf
[18:06:14] <kb8wmc> yes
[18:06:39] <psha> may you try to install libgl1-mesa-swx11 package?
[18:06:41] <kb8wmc> had to go to root recovery mode to get xorg.conf changed back
[18:06:55] <psha> theoreticaly it may solve issues with gl+rtai
[18:07:01] <psha> but i have not tried it
[18:07:26] <kb8wmc> rgr...will check in synaptic...thanks for your help
[18:07:47] <psha> if it is then it'll be far more simple solution to theese issues
[18:09:15] <andypugh> Yes, let us know how it goes, it could be put on the Wiki
[18:10:27] <kb8wmc> will do Andy
[18:25:33] <kb8wmc> looking in synaptic at the packages that will be removed is "ubuntu-desktop"...I am uncertain that I want to do that...any input?
[18:27:08] <psha> only desktop or bunch of packages too?
[18:27:30] <kb8wmc> it indicates it is limited to the desktop
[18:27:40] <psha> libgl1-mesa-swx11 is software rasterizer replacing GLX one
[18:27:57] <psha> ubuntu-deskopt is metapackage depending on all other desktop packages
[18:28:08] <psha> it's 10.04?
[18:28:18] <kb8wmc> it does also remove 3 other mesa packages, which I would expect
[18:28:30] <psha> http://packages.ubuntu.com/lucid/ubuntu-desktop
[18:28:31] <kb8wmc> yes 10.04
[18:28:31] <psha> this one?
[18:28:55] <psha> heh, it depends on libgl1-mesa-glx :)
[18:29:35] <psha> you may try to remove it and if it would not help - reinstall
[18:30:01] <psha> but don't confim 'autodeletion' of packages
[18:30:13] <cradek> ubuntu-desktop is fine to remove
[18:30:37] <cradek> you might want to put it back if you ever want to do an online upgrade to the next LTS, but other than that, it's no problem
[18:31:43] <kb8wmc> cradek: from the above link, it lists quite a few other package dependencies....
[18:32:04] <psha> kb8wmc: it's a 'metapackage'
[18:32:12] <psha> empty body but many dependencies
[18:32:23] <psha> it's used to ensure that all needed packages are installed
[18:33:12] <psha> it's safe to remove it if you won't call 'autoremove' later :)
[18:33:39] <kb8wmc> psha: I will give it a try then...
[18:35:51] <kb8wmc> psha: where is the confirmation of "autodeletion" of packages, found?...I have never used it
[18:36:18] <psha> aptitiude tries to do it on every opertation
[18:36:27] <psha> apt-get only when 'autoremove' command is issued
[18:36:37] <kb8wmc> ok,
[18:36:38] <psha> and i've not used synaptics
[18:36:40] <psha> :)
[18:37:19] <psha> hope it's like apt-get and won't do it untill you explicitly ask it
[18:37:47] <kb8wmc> going to find out shortly
[18:39:03] <kb8wmc> going to reboot now...tnx for help
[18:42:52] <kb8wmc> well, fyi all, I didn't bork the computer, and Axis now starts without locking up the computer, that seemed to fix the problems with locking up
[18:43:05] <cradek> yay
[18:43:20] <andypugh> That's excellent news
[18:43:46] <kb8wmc> tnx cradek, andy, and psha
[18:44:01] <andypugh> I wonder if the same approach would let me run Axis in an X-session through ssh?
[18:45:06] <kb8wmc> don't know, I only felt that the problem involved the video components and was not certain...it very well may be of help andy
[18:45:08] <cradek> no, I think you need to fix the xserver if you're having that problem
[18:45:22] <cradek> xserver = screen you're looking at
[18:45:49] <psha> may someone document this workaround?
[18:46:14] <kb8wmc> I have to bail out for a bit, thanks again folks for all the help
[18:46:14] <psha> i'm too bad in writing texts larger then 2 strings :)
[18:46:28] <JT-Work> any suggestions? http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/id,4818/catid,9/limit,6/limitstart,6/lang,english/
[18:46:56] <psha> JT-Work: config.log is needed
[18:46:58] <cradek> yes, install the build dependencies. he probably has no compiler at all.
[18:47:10] <JT-Work> ok, thanks
[18:47:33] <psha> cradek: at least he has autotools for autogen.sh :)
[18:47:47] <cradek> hm
[18:49:21] <Jymmm> kb8wmc: When you renewed your ticket, did you do it at fcc.gov? If so, was there any fees?
[19:58:19] <kb8wmc> Jymmm: yes, did it online
[19:58:23] <kb8wmc> no fees
[20:04:27] <SadMan> bah, livecd boots ok but system installed from it boots to black screen
[20:05:26] <skunkworks> SadMan: what is the system?
[20:07:17] <SadMan> skunkworks: figured it out, i've switched monitor to other input while booting so it probably didn't detect the display
[20:28:16] <psha> kb8wmc, andypugh: may somebody docuement libgl1-mesa-swx11 workaround on wiki?
[20:29:41] <andypugh> Well, anyone can, and it was your idea, wasn't it?
[20:30:03] <psha> my but i'm very bad in writing texts in english
[20:30:38] <psha> even in russian it's a great problem for me to put several sentences together in text :)
[20:31:28] <andypugh> OK, create a page with the facts in, and I can make it onto an article.
[20:33:39] <cradek> it would be great to have a url to point to when this comes up
[20:35:40] <psha> i'm addint to troubleshooting
[20:39:59] <psha> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TroubleShooting#R128_display_issue_with_Lucid_Install
[20:40:46] <psha> i've put facts i'm aware off
[20:45:05] <psha> and now i'll leave you :)
[20:45:33] <andypugh> OK, I will have a look through later
[20:49:08] <spawn> realitime system did not load, shutting down and cleaning up EMC2
[20:49:22] <spawn> RTAPI: ERROR: could not open shared memory(erno-=2)
[20:49:34] <awallin> do you have a realtime kernel?
[20:53:09] <spawn> i am using the cd provided by the project
[20:53:14] <spawn> a fresh install
[20:53:37] <awallin> does the sim config work? what config is problematic?
[20:53:41] <cradek> spawn: pastebin your dmesg?
[20:53:44] <spawn> Isim config?
[20:54:02] <spawn> one sec cradek thx
[20:56:03] <Jymmm> kb8wmc: Ok, thanks.
[20:56:25] <Jymmm> kb8wmc: I thought there was a renewal fee.
[20:56:27] <spawn> pastebin.com/6bgHta4x
[20:57:04] <spawn> i have rtai
[20:57:24] <awallin> apic tuning in bios?
[20:57:32] <cradek> or add lapic on the kernel command line
[20:57:42] <cradek> where is our relevant instruction page...?
[20:58:47] <cradek> http://www.mailinglistarchive.com/html/emc-users@lists.sourceforge.net/2010-09/msg00106.html
[20:59:41] <cradek> or yes, perhaps a bios setting
[21:01:14] <spawn> ok thx
[21:01:16] <cradek> if you cannot get lapic to work one of those two ways, you'll have to use the 8.04 hardy install
[21:01:31] <cradek> (or build a rtai kernel with different settings for your lucid system)
[21:01:39] <spawn> ok cool, I was about to do that
[21:01:50] <cradek> this is a problem with relatively old motherboards/cpus
[21:02:33] <cradek> the advantage of using this setting is we get SMP support for multiprocessor systems, but at the expense of some old systems like P2s
[21:04:04] <spawn> nope
[21:04:36] <spawn> this mb is from 2005 not 1995
[21:05:19] <cradek> spawn: what kind of cpu?
[21:05:50] <spawn> VIA Nehemiah 1ghz
[21:06:20] <cradek> check bios for apic-related settings, I guess
[21:06:26] <Jymmm> Q: Is a dual atom 32 or 64 bit?
[21:07:01] <cradek> or try the instructions at that url
[21:08:47] <SWPadnos> the 330 is 64-bit, with HT, but no VT (I think)
[21:08:56] <SWPadnos> I imagine the 510 is about the same
[21:11:03] <skunkworks> I really need to video tape how fast the k&t boots
[21:27:29] <spawn> hm
[21:27:36] <spawn> spawn is now known as CrunkWorks
[21:32:29] <kb8wmc> boy-o-boy, it feels good to have Axis running smoothly
[21:33:27] <andypugh> cradek will be trying to convert you to the Touchy side soon
[21:33:47] <kb8wmc> aha, something to contemplate then
[21:34:06] <kb8wmc> tnx again for your help andy
[21:37:32] <DaViruz> the touchy side has me in a firm grip
[21:37:44] <DaViruz> no more chips in the keyboard
[21:39:12] <DaViruz> (i guess there are probably more ways to avoid that particular problem)
[21:40:46] <andypugh> I am beginning to realise that it is not coincidence that none of the world's great chefs are famous for coding C at the same time as cooking.

[21:41:30] <SWPadnos> those suck unless you restrict yourself to one-finger typing
[21:41:39] <SWPadnos> maybe two (one on each hand)
[21:43:05] <DaViruz> i guess i can live with that, the longest stuff i type is g0x0y0z50
[21:43:47] <DaViruz> probably not worse than the on screen keyboard in touchy
[21:44:24] <SWPadnos> I'm not sure. my touchscreen is only 800x600, and I haven't tried touchy on it
[21:44:49] <SWPadnos> the rubber keyboard I have, which is the best of the few that I tried, is still not very good for typing
[21:45:22] <SWPadnos> for poking at individual keys, it's not too bad (and on a good day, on a good surface, you can almost type on it)
[21:46:08] <DaViruz> as long as the planets don't have to be lines up
[21:46:19] <SWPadnos> no, it seems to be astronomically independent

[22:59:35] <andypugh> Is your name particularly apt?
