[00:04:06] <theorb> theorb is now known as theorbtwo
[04:24:10] <spasticteapot> Anyone here familiar with old-fashioned cutting lasers?
[04:24:35] <atmega> I happen to be an expert on 19th century lasers
[04:25:07] <spasticteapot> lulz
[05:13:02] <Jymmm> Lasers are old fashioned?
[05:13:45] <Jymmm> Oh yeah, I always see the old B&W of the laser sitting next to the wood burning stoves
[05:14:15] <elmo42> >_<
[05:16:16] <Jymmm> spasticteapot: Did you have a question?
[05:16:36] <spasticteapot> Yes.
[05:16:49] <Jymmm> Then just ask
[05:17:01] <spasticteapot> I've found some great big lasers on laserresale.com and was wondering exactly what would be involved in setting one up.
[05:17:22] <spasticteapot> Currently trying to find the blasted thing. :(
[05:17:47] <spasticteapot> http://www.laserresale.com/?fa=app.view&it=5404
[05:18:02] <spasticteapot> The price is right, but it's, well...a huge old monstrosity.
[05:23:49] <spasticteapot> Jymmm: So...what *is* this thing?
[05:26:13] <atmega> we have an old CO2 laser at work that is physically very similar
[05:26:57] <elmo42> spasticteapot: you need a supply of CO2.
[05:27:19] <spasticteapot> elmo42: Does it need to be a mix specific to this laser, or just plain CO2?
[05:27:35] <spasticteapot> Also, do you know what sort of maintenance or service must be performed on a lump like this?
[05:27:47] <atmega> ours uses some odd mix, not just co2
[05:27:49] <spasticteapot> And do you have any thoughts on using mirrors to build a "flying head" laser setup?
[05:28:17] <spasticteapot> atmega: Is this the sort of thing you can buy off the shelf, or is it loopy expensive and only sold by the manufacturer?
[05:28:34] <atmega> it comes from our regular gas supplier
[05:28:54] <atmega> no idea on cost/ease of use/etc
[05:29:19] <atmega> we weld zircalloy and inconel with it
[05:29:36] <spasticteapot> All I know about inconel is that it's a bugger to work with and worth more than I am.
[05:30:12] <elmo42> lol
[05:30:14] <spasticteapot> Do you know if this sort of laser is generally able to be throttled down to 1/2 power output?
[05:30:21] <elmo42> says it pulses
[05:30:33] <spasticteapot> elmo42: Do you think that can be turned off?
[05:30:41] <spasticteapot> I suppose I should just call the vendor....
[05:30:53] <atmega> power is controlled by shutter-open time
[05:31:19] <elmo42> what I mean is it can be pulsed.
[05:31:32] <elmo42> it does constant ON, but it can also pulse
[05:32:19] <spasticteapot> Hmm.
[05:32:30] <atmega> we used to have some 2500w YAG lasers, they were incredibly expensive water heaters
[05:32:41] <spasticteapot> Anywho, does anyone have any thoughts on using mirrors and moving optics?
[05:33:08] <spasticteapot> In theory, it allows you to have a much faster cutting speed on the laser, but I'm not sure if you can really do it with a 750W laser.
[05:33:41] <spasticteapot> OTOH, were it possible to do so, it would drop the cutting time for MDF down to nothing. :)
[05:36:41] <elmo42> you worried all that much about cutting time?
[05:37:03] <elmo42> unless the machine is run 24/7 cutting time is almost irrelevant
[07:45:35] <root> root is now known as Guest72914
[07:45:42] <Guest72914> Guest72914 is now known as minorursa
[07:48:21] <minorursa> "can not mount /dev/loop0 " etc. Any suggestions, anyone?
[07:49:14] <minorursa> Anyone home, or is everbody lurking?
[07:49:28] <psha> :)
[07:49:39] <psha> please more details
[07:49:47] <psha> what is mounted? how? who?
[07:50:07] <minorursa> downloaded latest release, burned ISO, boot goes through some grinding, and then
[07:50:55] <minorursa> the message Can not mount /dev/loop0 (/cdrom/casper/filesystem-squashfs) on //filesystem squashfs
[07:51:14] <psha> that's all?
[07:51:18] <archivist> google can not mount /dev/loop0
[07:51:43] <minorursa> pretty much. There's a message about ash running.
[07:51:55] <psha> look into dmesg
[07:52:48] <psha> maybe corrupted CD?
[07:53:07] <psha> try check cd from boot menu first
[07:54:02] <minorursa> bottom of the dmesg file: "Major/minor mismatch, older Squashfs 3.1 filesystems are not supported
[07:54:18] <minorursa> Huh? This is supposed to be running from a live CD.
[07:54:49] <minorursa> Suspect a bad CD?
[07:54:58] <psha> yes
[07:55:20] <minorursa> Done. I'll try again tomorrow (local time is 4 am).
[07:55:25] <psha> :)
[07:55:38] <psha> btw what iso version?
[07:55:40] <psha> 10.04?
[07:55:50] <minorursa> yes, 10.04
[07:56:00] <minorursa> downloaded earlier this evening
[07:56:11] <psha> there is (must be) 'check cd' entry in boot menu
[07:56:16] <psha> so try it
[07:56:34] <minorursa> hang on, and I'll see if I can get to it.
[07:56:51] <psha> at least for me this image is working
[07:57:00] <psha> also it's useful to check md5 of downloaded iso image
[07:57:57] <minorursa> cd being checked now
[07:58:37] <minorursa> check ended with same message--can not mount . . .
[08:00:22] <psha> so it's corrupted
[08:00:32] <minorursa> Looking a ls shows the file in question (filesystem.squashfs) has over 700 meg. Huh? Must be corrupt.
[08:00:39] <minorursa> We try again tomorrow.
[08:00:44] <psha> no, it's ok
[08:00:56] <psha> try md5sum filesystem.squash
[08:01:00] <psha> i'll check mine
[08:01:51] <psha> 0bee86ae9ac2fdb468b49d62de89906c /mnt/tmp/casper/filesystem.squashfs
[08:03:31] <minorursa> Much thanks. I'll work on it tomorrow.
[08:03:42] <minorursa> Thanks for the ear, and the suggestions.
[10:09:11] <Paragon39> jepler: Are you available?
[10:11:13] <theorbtwo> If there is one, then a torrent will have the nice effect of re-downloading only the corrupted bits.
[10:17:28] <Paragon39> I there anyone available that has pluto-step experience?
[10:32:45] <boot|sleep> boot|sleep is now known as bootnecklad
[11:12:05] <Jymmm> cradek_: Now, if they only had a wired version, this might be slick for use with Touchy http://www.apple.com/magictrackpad/
[11:21:26] <psha> Jymmm: just a bit cheaper then touchscreen :)
[11:21:46] <Jymmm> a lot cheaper
[11:22:24] <psha> 70$? acoustic ts for 17" are sold for ~90$ here
[11:22:44] <Jymmm> link?
[11:23:11] <psha> http://www.touchbaza.ru/catalog/sensors_screens/saw/147
[11:23:24] <psha> 1$ ~ 28 rubles
[11:23:35] <psha> 30
[11:23:47] <Jymmm> that's an overlay
[11:23:53] <psha> yes
[11:24:09] <Jymmm> it's also 4:3 ratio, meaning CRT, not LCD.
[11:24:18] <psha> it's mountable on nearly every 17" tft screen
[11:25:07] <psha> 17" 4:3 tft's are still popular
[11:25:22] <Jymmm> Maybe in Russia
[11:25:24] <Jymmm> =)
[11:26:00] <psha> dunno how it's across the border :)
[11:26:22] <psha> payment terminals are very popular here in last years so ts displays are pretty cheap
[11:26:24] <Jymmm> Wide Screen 16:9 or 16:10 Ratio
[11:26:47] <Jymmm> Even on netbooks
[11:28:40] <psha> I switched to 16:10 monitor last year too
[11:29:01] <psha> but 4:3 are sold starting at ~100$
[11:29:06] <psha> new
[11:29:20] <psha> also u may buy used one very cheap
[11:29:51] <psha> old TN matrices were not too nice so people sell their old ones
[11:30:06] <Jymmm> Yeah, CRT's are just not worth it these days. I have a 23" Samsung that does 2048 natively, which means I have full two-page layout! I just love that, too bad they discontinued it.
[11:30:20] <Jymmm> and cheap too
[11:30:29] <Jymmm> ~$150 USD
[11:32:10] <psha> Heh, large CRT's were large
[11:32:17] <psha> very large
[11:32:24] <psha> and heavy
[11:32:56] <Jymmm> I still have a 24" Sony Trinitron @ 68lbs. It just sits around as a backup.
[11:33:06] <Jymmm> Those things just never die!
[11:35:53] <psha> :) Already have a backup tft :)
[11:35:57] <psha> 17" 4:3 :-P
[11:36:53] <psha> I checked prices for TS since there is posibility that I'd have to build setup with it
[11:37:08] <Jymmm> ah
[11:37:42] <psha> And magicktrackpad has one small disadvantage
[11:37:59] <psha> I expect that it behaves like 'relative' input device, not 'absolute'
[11:38:15] <psha> So it's like any other mouse
[11:38:53] <psha> btw have you considered trackballs?
[11:39:05] <psha> Thay are popular among medical equipment
[11:39:47] <Jymmm> That's all I use. Kensington 4 button TrackBalls
[11:40:41] <Jymmm> http://us.kensington.com/html/2200.html
[11:40:50] <Jymmm> cue ball sized
[11:42:11] <psha> How it's compared to mouse? Comfortable?
[11:42:25] <Jymmm> BL: Left Click, BR: Right Click, TL: Copy, TR: Paste, Chord Top: Cut, Chord Bottom: Browser Back
[11:43:54] <Jymmm> I've used this and the previous generation trackball for over 7 years. I don't have any wrist fatigue, when I use a regular mouse (like if I'm working on someone else computer, I can feel the strain after a couple of hours.
[11:44:11] <Jymmm> maybe more like nine years.
[11:46:21] <psha> Long enough to be confident in trackballs :)
[11:46:31] <psha> I've never used them :)
[11:46:44] <Jymmm> and to request one when starting a new job too.
[12:09:27] <jthornton> jthornton is now known as JT-Mississippi
[12:09:45] <Jymmm> JT-Mississippi: ???
[12:10:00] <JT-Mississippi> hi Jymmm
[12:10:15] <JT-Mississippi> I'm at Biloxi, MS
[12:10:19] <Jymmm> JT-Mississippi: whatcha doin there?
[12:10:23] <JT-Mississippi> down on the beach
[12:10:33] <Jymmm> ah
[12:10:53] <JT-Mississippi> drinking coffee and watching the shrimp boats come in
[12:10:59] <Jymmm> heh
[12:11:58] <JT-Mississippi> doesn't archivist cut gears with EMC? http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/id,4488/catid,30/
[12:12:19] <Jymmm> I think so
[12:12:32] <JT-Mississippi> that's what I thought too
[12:51:30] <JT-Mississippi> here it is http://www.youtube.com/user/davethearchivist#p/a/u/1/HAtziCsUj5Q
[12:52:55] <Paragon39> is there a way to get more vertical divisions (squares) in hal scope?
[12:54:13] <Paragon39> The current default is 10X10...
[13:24:05] <salvarane> hello I must to configure joypad for emc 2.4 this are the options that I see throght halmeter http://pastebin.com/ZiBEkvJL
[13:24:26] <salvarane> and my configure minimal are this http://pastebin.com/pEDbkvye
[13:25:07] <salvarane> My problem is that the my joypad is very limited http://imagebin.org/116668 and the option input.0.abs-rz-position not is present to in halmeter,
[13:25:07] <salvarane> for this I'm not possible connect and movie the axis Z.
[13:25:17] <salvarane> Is possible that I can connect the axis Z througth a generical button and the axis X or Y for movie the axis Z.
[13:26:08] <JT-Mississippi> you should be able to use any button for anything
[13:27:28] <salvarane> I don't know as do this operation
[13:28:48] <JT-Mississippi> once you have your joypad connected and EMC sees it then you can use Machine/Show Hal Configuration to view the pins
[13:29:05] <salvarane> ok
[13:30:35] <salvarane> the pins of my joypad return from halmeter http://pastebin.com/ZiBEkvJL
[13:30:51] <JT-Mississippi> you can add a pin to the watch window to see it's operation as you press/move it
[13:32:25] <salvarane> could you please to do example
[13:32:42] <JT-Mississippi> this is how I hooked up my joypad for my plasma http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Simple_Remote_Pendant
[13:33:27] <salvarane> I saw this wiki yesterday
[13:34:01] <salvarane> but the problem is that the pin not are equals
[13:34:55] <JT-Mississippi> you have to adapt
[13:35:50] <JT-Mississippi> this is a very short understanding of HAL commands http://www.linuxcnc.org/docview/html//hal_basic_hal.html
[13:36:28] <salvarane> for example I have the buttom 1, free , how can I connect this buttom together axis X for moving the axis Z ?
[13:37:32] <Jymmm> Does anyone have any tricks to finding the center of a circle drawn on a flat plate?
[13:37:36] <JT-Mississippi> you would have to use some HAL logic componets
[13:38:20] <salvarane> whats are
[13:38:28] <JT-Mississippi> Jymmm: I use to know but forgot
[13:38:48] <Paragon39> Hello could someone please take a look at the following EMC forum post as I am currently pulling my hair out :-( http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,38/id,4483/lang,english/#4493
[13:39:19] <Jymmm> JT-Mississippi: let me know if you remember please
[13:39:30] <JT-Mississippi> salvarane: scroll down on this page for a list of all componets http://www.linuxcnc.org/docview/html/
[13:39:58] <salvarane> thanks I look at
[13:40:20] <JT-Mississippi> Jymmm: http://www.mathopenref.com/constcirclecenter2.html
[13:40:58] <Jymmm> JT-Mississippi: Heh, I just found that too =)
[13:41:07] <JT-Mississippi> dang I missed the change to do "let me google it for you"
[13:41:15] <JT-Mississippi> chance
[13:41:51] <Valen> google "that"
[13:42:53] <Jymmm> JT-Mississippi: This is slick... http://www.mathopenref.com/thalestheorem.html
[13:43:41] <JT-Mississippi> pretty neat Jymmm
[13:44:16] <Paragon39> That's Cool...
[13:44:22] <Jymmm> JT-Mississippi: It's always nice to know WHY shit works =)
[13:44:37] <JT-Mississippi> yea, I'm the same way
[13:45:49] <Paragon39> I wish I knew why pluto-step does not ;-)
[13:46:25] <JT-Mississippi> I think the pluto guy monitors the mailing list, not sure if he visits the forum
[13:46:47] <Paragon39> Is that Jepler?
[13:46:56] <JT-Mississippi> I do recall something about a math problem with a pluto driver...
[13:47:14] <JT-Mississippi> jon something I think
[13:47:51] <Paragon39> JT-Mississippi: did you look at the scope image I posted?
[13:48:26] <JT-Mississippi> yes
[13:48:46] <salvarane> sorry but this informations is too , and the example is not exhaustive, this is the general information, not specific about this argoment joypad and all possibilities
[13:49:20] <Paragon39> Weird huh.. when the Y neg is commanded it feeds back to the Z axis!
[13:50:28] <Paragon39> The problem I not sure is weather it is EMC or the Pluto firmware?
[13:50:59] <JT-Mississippi> it is weird I would post this question on the mailing list
[13:51:12] <Paragon39> mailing list?
[13:51:55] <JT-Mississippi> salvarane: you won't find anything that lists all possibilities for a joypad
[13:51:57] <cpresser> https://lists.sourceforge.net/lists/listinfo/emc-users
[13:52:07] <Paragon39> Thanks
[13:55:39] <salvarane> the component of the emc are too, and they uses are not clear for me whit this documentation , exist a document that explain with examples the uses of this component and the field of the applications
[13:58:07] <cpresser> salvarane: did you take a look at the integrators_manual?
[13:59:36] <JT-Mississippi> salvarane: the place to start if you know nothing about HAL is here http://www.linuxcnc.org/docview/html//hal_basic_hal.html
[14:00:01] <JT-Mississippi> it explains the basics and gives some examples
[14:01:50] <salvarane> ok thanks in the section 5 of the integrators manual there is something, I look at
[14:04:26] <JT-Mississippi> one trick I use is to write the logic down in English (or your favorite language) of each thing I want to do in HAL
[14:05:30] <JT-Mississippi> for example "if button 1 is on and switch 2 is on turn output 3 on"
[14:06:10] <JT-Mississippi> then find the proper HAL command to replace each logic part and do one at a time till you get to know the commands
[14:07:48] <JT-Mississippi> then test each line as you add them...
[14:08:44] <Paragon39> JT-Mississippi: I have just posted a message to the mailing list... but how do I view it?
[14:09:15] <JT-Mississippi> you will get a copy if you subscribed to it
[14:10:13] <salvarane> the method be like the pointers of the language C
[14:11:31] <salvarane> a component point another component and so forth
[14:11:31] <Paragon39> I have subscribed and have sent a message but have not received a reply as yet does it take a while, also did I need to check 'Would you like to receive list mail batched in a daily digest?' to receive them?
[14:12:16] <Paragon39> Or is it I only see replies when someone else makes one?
[14:12:58] <salvarane> <JT-Mississippi> thanks for your patiece, I must study this manual.
[14:13:12] <salvarane> sorry patience
[14:13:33] <JT-Mississippi> no problem salvarane
[14:13:45] <cpresser> Paragon39: you should see your own message on the list
[14:13:51] <cpresser> as well as any answers
[14:14:03] <JT-Mississippi> Paragon39: I use individual e-mails it seemed simpler to me
[14:14:07] <cpresser> I ee your list :)
[14:14:12] <cpresser> ~see
[14:14:26] <cpresser> "I see your mail" dammit. i am to dumb to type :D
[14:14:41] <Paragon39> I cant find it... lol
[14:15:05] <cpresser> you can use your mail-clients thread-view. it gets you a better overview on the list
[14:16:20] <Paragon39> I am using googlemail but cant find the post!
[14:45:19] <JT-Mississippi> http://www.linuxcnc.org/component/option,com_kunena/Itemid,20/func,view/catid,10/id,4454/lang,english/#4492
[14:45:40] <JT-Mississippi> anyone notice this on your install
[14:46:19] <alex_joni> he probably has GEOMETRY in his config
[14:46:37] <alex_joni> or something like that, it's surely not 10.04 related, he should post his ini
[14:46:45] <JT-Mississippi> ok
[14:59:53] <Paragon39> Am I right in understanding the following... 'Xpos-cmd axis.0.motor-pos-cmd => pluto-step.stepgen.0.position-cmd' states axis.0.motor-pos-cmd passes info to Xpos-cmd then Xpos-cmd passes it onto the pluto-step.stepgen.0.position-cmd?
[15:24:15] <JT-Mississippi_> JT-Mississippi_ is now known as JT-Mississippi
[16:19:04] <Paragon39> Hi, How does one get rtapi_print_msg to print to standard out ?
[16:21:53] <Paragon39> or rarther were does the output for rtapi_print_msg(RTAPI_MSG_INFO, go
[16:25:24] <psha> "master" process i think
[16:25:54] <psha> whic starts all stuff
[16:26:03] <psha> at least it behaves like this )
[16:26:33] <Paragon39> psha: do you know how do I see the message is it in a log file?
[16:27:00] <psha> replace INFO with ERR and you'll see in on console :D
[16:27:28] <psha> i don't know where INFO messages goes, used ERR for debugging :)
[16:27:36] <Paragon39> I tried that but it also scrolls over the AXIS gui
[16:52:41] <Endeavour_> Endeavour_ is now known as Endeavour
[16:54:27] <Tech_Talk> Tech_Talk is now known as Birdman3131
[16:54:40] <root> root is now known as Guest71291
[16:54:47] <Guest71291> Guest71291 is now known as minorursa
[16:55:05] <minorursa> looking for help with problem installing 10.04
[16:55:15] <minorursa> anybody care to try?
[16:56:18] <minorursa> Nobody home?
[16:56:59] <minorursa> OK, I'll return later.
[18:08:08] <minorursa> Anyone home who would like to tackle an install problem?
[18:12:59] <SWPadnos> what actually happened?
[18:14:24] <minorursa> I burned a CD, and the system cannot mount the squashfs filesystem. It turns out that it has mounted one of the partitions on my disk
[18:14:46] <minorursa> as cdrom, and then tries to mount an old version of the file on loop0.
[18:14:58] <minorursa> I can provide the various messages if this is not clear.
[18:18:42] <minorursa> ???
[18:23:47] <SWPadnos> well, I'm not sure what's going on there
[18:24:13] <SWPadnos> could be a bad CD burn, but it could be something else entirely
[18:29:36] <psha> minorursa: have you checked md5 sums?
[18:30:04] <minorursa> I find that /cdrom is mounted on a partition of my hardrive that has an old ISO, and the system is trying to mount on an older version of the squashfs system.
[18:30:09] <minorursa> Yes, md5 is fine.
[18:34:20] <minorursa> SWPadnos: What other info do you need?
[18:35:16] <psha> minorursa: please a bit more about partions & old iso
[18:35:27] <psha> it's written there directly?
[18:36:23] <minorursa> drive has 4 partitions, listed by df as sda1-4. /cdrom is mounted on sda4. iso is the iso from which I installed Heron.
[18:36:23] <tom3p> maybe rename/move 'older version of the squashfs system' to see if correct one will load?
[18:37:53] <psha> Or if it has iso filesystem just temporary kill superblock
[18:40:47] <minorursa> I'm waiting for boot now so I can rename the file. How to I kill superblock?
[18:42:09] <psha> What is filesystem on that partition?
[18:42:36] <psha> If it's possible to mount it in read-write mode then just rename casper subdir
[18:43:07] <minorursa> I have renamed the file and am waiting for reboot from CD
[18:43:47] <minorursa> if that doesn't work, I will rename the directory (casper).
[18:45:12] <minorursa> It doesn't work. This time, the system attempted to mount the file with the changed name. Grump.
[18:45:38] <minorursa> psha: ext3
[18:47:47] <psha> try to rename casper subdir
[18:48:06] <psha> and set 000 permissions for sure )
[18:48:21] <minorursa> boot with renamed directory is now in progress
[18:49:24] <minorursa> seems to be working
[18:51:39] <minorursa> reading the heck off the CD, and taking its sweet time. It's an old machine (750 MHz).
[18:56:33] <minorursa> Well, it works, sorta. I have started, and killed EMC. Clicking on the latency test menu item does nothing, however.
[18:57:03] <SWPadnos> run it from a terminal and see why it doesn't run
[18:57:06] <SWPadnos> latency-test
[18:57:22] <minorursa> It might be worth a note somewhere that any old directories named casper should be renamed before attempting boot from the CD.
[18:57:49] <SWPadnos> yeah, that is strange that it tried to read stuff off the hard drive
[18:58:19] <SWPadnos> but I guess it makes sense - that could have been a USB flash drive with your personal data on it
[18:59:24] <minorursa> What (and where) is the latency test program, please?
[18:59:37] <psha> latency-test
[18:59:43] <psha> from console or Alt-F2
[19:00:08] <SWPadnos> terminal, not ALT-F2
[19:00:13] <SWPadnos> that way you get to see any error messages
[19:01:23] <psha> There is checkbox 'run in terminal' in alt-f2 :-P
[19:01:29] <minorursa> found it in /usr/bin. Pile of messages on termal
[19:02:01] <minorursa> first message is from insmod, operation not permitted.
[19:02:14] <psha> Second with same problem :)
[19:02:21] <SWPadnos> what's the kernel version
[19:02:23] <SWPadnos> ?
[19:02:25] <psha> 10.04
[19:02:31] <psha> 2.6.32-122 i think
[19:02:50] <minorursa> RTAPI could not open shared memory. Kernel is whatever is on the live CD.
[19:02:52] <SWPadnos> not what it's supposed to be, what it is ;)
[19:02:57] <SWPadnos> uname -a
[19:02:59] <psha> :)
[19:03:35] <minorursa> 2.6.32-122-rtai
[19:04:51] <SWPadnos> ok, lsmod | grep rtai
[19:06:55] <minorursa> it's not there. The message said that loading the module failed.
[19:07:09] <SWPadnos> yep. try it anyway
[19:07:35] <minorursa> "Operation not permitted."
[19:07:46] <SWPadnos> lsmod is not permitted?
[19:10:37] <minorursa> No, loading the module, specifically rtai_hal.ko
[19:11:10] <psha> dmesg | tail
[19:11:48] <SWPadnos> one possible reason for not being able to load a module is if it's already loaded. that's what I'm trying to get you to find out, usinf "lsmod | grep rtai"
[19:13:40] <minorursa> lsmod says it is not there. dmesg says local apic configured but not available.
[19:14:01] <minorursa> insmod on other modules in the directory gets the same "operation not permitted."
[19:15:16] <SWPadnos> ah. go into BIOS setup and make sure that APIC (or local APIC, or HPET ...) is/are enabled
[19:16:17] <minorursa> I'm pretty sure that there is no option for that, but I could easily be wrong. I'll check now.
[19:16:50] <tom3p> (SWPadnos, if its any use, i running EMC2 right now and 'lsmod | grep rtai' just returns the prompt)
[19:17:09] <SWPadnos> sim? :)
[19:17:17] <tom3p> yep sim 5axis
[19:17:30] <SWPadnos> heh. that's not what I meant, but still
[19:18:04] <SWPadnos> I'm pretty sure there should be some modules named *rtai* if you're running RT, but that could have changed
[19:19:00] <minorursa> confirmed, there is nothing in the bios setup about APIC.
[19:19:11] <Jymmm> O_o
[19:19:41] <minorursa> rebooting CD now. I'll check if any rtai modules have been loaded as soon as I have a terminal.
[19:20:14] <SWPadnos> if EMC ran, then modules should have been able to load
[19:20:26] <tom3p> (SWPadnos, very very odd, my scroll back shows it didnt exist, yet now it does)
[19:20:35] <minorursa> didn't get past the select config screen
[19:20:56] <SWPadnos> it is possible that the RTAI kernel on the 10.04 CD can't support certain older motherboards, since I get the feeling that local APIC is required
[19:21:11] <SWPadnos> but I've been a bit out of touch lately, so I could be all wrong
[19:21:27] <minorursa> and this is an old machine, with an old motherboard.
[19:22:12] <psha> minorursa: look in irc logs
[19:22:24] <psha> you are second this week with same problem
[19:22:45] <minorursa> anyone remember the solution?
[19:22:47] <psha> logger_emc: bookmark
[19:22:47] <psha> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-10-02.txt
[19:23:47] <psha> minorursa: nothing good )
[19:24:31] <psha> minorursa: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2010-09-27.txt
[19:24:35] <psha> search for lapic
[19:25:10] <psha> ~17:30
[19:27:38] <tom3p> http://pastebin.com/KjCsT39L
[19:28:15] <acemi> minorursa: afaik you need to compile a new rtai kernel with a disabled lapic support
[19:30:11] <minorursa> I think I may just stay with 2.3, since it is giving me pretty much what I want, but it would be nice to upgrade. The nuisance of making a new kernel is
[19:30:44] <minorursa> a bit much, especially because I have a packed weekend as it is. Thanks for help.
[19:31:18] <minorursa> Checked the log, and there is no solution given there. Just a note that it looks bad.
[19:31:56] <minorursa> For future reference, where is the source for an emc-patched kernel?
[19:32:27] <minorursa> If the kernel is patched, that is.
[19:33:45] <SWPadnos> you could try 8.04
[19:34:48] <minorursa> 8.04 is running fine. I was interested in upgrading without net connection, so I got the CD. I know that I can do an upgrade of 8.04 if I connect to the net.
[19:39:17] <minorursa> f6 at boottime offers a "noapic" option and a "no loapic" option. How do I activate these?
[19:41:36] <minorursa> got it. No need to answer last question
[19:53:34] <minorursa> Thanks for the help, folks. I'll do some tinkering, but am not hopeful. Unfortunate.
[20:31:19] <minorursa> for all who tried to help me with 10.04, here is the solution: add lapic to the boot line. Picked that up off http://www.mail-archive.com/emc-users@lists.sourceforge.net/msg22482.html
[20:38:34] <spasticteapot> elmo42: Do you have any experience cutting MDF or plywood with lasers?
[20:38:57] <spasticteapot> From what I understand, the more power you use, the faster you can cut, and the the neater the end results are.
