[00:00:04] <jthornton> 5 down one to go
[00:33:42] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[00:45:00] <MarkusBec> MarkusBec is now known as MarkusBec_away
[03:19:33] <dmess> hi all
[03:36:07] <Jymm> howdy
[03:44:25] <dmess> hi J
[05:23:32] <ZeroFlex> morning
[05:26:33] <Patrice> Has anyone installed gcnccam?
[05:27:14] <Patrice> sudo apt-get install libgnomeuimm-2.6-1c2a -OK
[05:27:59] <Patrice> but the next command line does not work: sudo dpkg -i gcnccam_0.4.4-1_i386.deb
[05:30:55] <Jymm> doesn't look like it's had any updates for 18 months
[05:31:03] <Jymm> hasn't
[07:09:36] <numen> hi
[07:11:28] <numen> i ve problem using emc2, i have still joint2 following error, can anyone explain me, how i can fix that?
[07:15:35] <numen> in the shell it is emc/task/taskintf.cc 607: error on axis1, command number 117
[07:42:18] <micges_work> numen: what is your config (steppers. servo)?
[07:51:37] <alex_joni> numen: check dmesg
[07:51:41] <alex_joni> micges_work: it's steppers
[07:51:48] <alex_joni> in dmesg there is the exact cause
[07:51:52] <alex_joni> probably misconfiguration
[07:51:54] <numen> steppers
[07:55:41] <numen> but where
[07:55:54] <alex_joni> numen: open a terminal, and type 'dmesg'
[07:56:01] <alex_joni> there will be a long list of messages
[07:56:08] <alex_joni> pastebin the last 50-100
[08:17:56] <numen> i found the mistake
[08:18:03] <numen> the velocity was to high
[09:21:14] <piasdom> g'mornin all
[09:21:37] <micges_work> hi
[09:32:30] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[10:45:06] <Valen> I Haz a shed
[10:45:31] <archivist> I haz a Denford Starturn cnc lathe
[10:46:09] <Valen> I have a mill that whines at me does that count?
[10:46:36] <archivist> mine is silent till I get at the wiring
[10:47:13] <archivist> I wish I could find the manual for the speed controller thats in it
[10:47:32] <archivist> old SCR dc drive
[10:50:40] <archivist> Valen, pcw left a reply for you after you went
[10:51:03] <Valen> I don't know how those work, SCR's only turn off when current is 0 innit?
[10:51:09] <MarkusBec> MarkusBec is now known as MarkusBec_away
[10:51:11] <Valen> have it handy archivist?
[10:51:20] <Valen> or where was the log stored?
[10:51:31] <Valen> I was going to dig through it to compose stuff for the list
[10:51:54] <archivist> logger_emc: bookmark
[10:51:54] <archivist> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-09-09.txt
[10:52:53] <archivist> basicly the whistle is likely the current limit
[10:53:36] <Valen> hmmm doesn't seem likley
[10:53:40] <Valen> could be though
[10:54:17] <Valen> hrmmm actually could be
[10:56:07] <Valen> though it doesn't explain why the halrun style of pushing wasn't working
[10:57:23] <Valen> yeahs there were 4 red LED's on, which indicates over current
[10:57:37] <Valen> which is really bad actually
[10:57:56] <Valen> it wasn't even moving the mill and only hitting 1.2 volts across the motor
[10:58:08] <alex_joni> Valen: there are 2 settings
[10:58:11] <alex_joni> for current limit
[10:58:22] <alex_joni> 7.5A and 15A if this is the same issue
[10:58:22] <Valen> yeah but even doubling it probably won't be enough
[10:58:36] <alex_joni> what's the motor rating?
[10:58:40] <Valen> 500W
[10:58:46] <alex_joni> voltage?
[10:58:47] <Valen> 36V
[10:59:03] <alex_joni> that's < 15A
[10:59:20] <Valen> thats why I figured the 400W drivers would do the job
[10:59:31] <alex_joni> yeah, but set to 200W they won't ;)
[10:59:48] <Valen> I would expect them to be able to at least move the thing though
[11:00:16] <Valen> i mean the torque output was way lower than it needed to actually move the mill
[11:01:06] <Valen> we put a handle on it and could quite easily spin it against the direction the motor was pushing
[11:01:18] <alex_joni> hmm
[11:01:35] <alex_joni> I'd wait for PCW later on
[11:02:22] <Valen> its motor current its limiting too which is a little bad too
[11:02:42] <Valen> if its pushing 7.5A at 1.2 volts thats only pushing ~10W into the motors
[11:03:11] <alex_joni> it should limit at 7.4A at 36V though
[11:03:20] <Valen> thats not motor current limit
[11:03:21] <alex_joni> what's your PSU?
[11:04:12] <Valen> that was running off a 12v supply so if it went nuts it would stay on the bed
[11:04:12] <Valen> we jacked it up to ~24v and the measured motor voltage was actually lower
[11:04:20] <Valen> but it might be seeing aliasing using the multi-meter to look at the PWMed waveform
[11:04:45] <jthornton> is there any way to test an onboard network card in Ubuntu?
[11:06:44] <Valen> plug it in and see if it works?
[11:07:41] <jthornton> it quit working and I swapped the cable to another computer and that works on the other computer
[11:07:58] <jthornton> so it is in the computer
[11:08:03] <Valen> ifconfig --all will tell you if its there
[11:09:39] <jthornton> ifconfig doesn't have an --all
[11:09:49] <jthornton> it has an --allmulti
[11:10:16] <Valen> ifconfig -a
[11:10:20] <alex_joni> ifconfig
[11:10:42] <jthornton> -a worked
[11:10:53] <alex_joni> does it say anything?
[11:11:15] <jthornton> link encap:local loopback
[11:11:32] <alex_joni> plug the cable in, and check dmesg
[11:11:36] <Valen> anything else?
[11:11:38] <jthornton> inet addr: Mask:
[11:11:39] <alex_joni> it should say linkup/down
[11:11:45] <alex_joni> that's teh wrong one
[11:11:52] <jthornton> no linkup/down
[11:12:01] <alex_joni> jthornton: the one starting with lo is the local loopback
[11:12:07] <alex_joni> you need to see an eth0, eth1
[11:12:21] <alex_joni> there's a column on the left
[11:12:35] <jthornton> I just did it on this computer and see the eth
[11:12:40] <alex_joni> if the first one you're seeing is lo, then it didn't detect any other cards
[11:12:43] <alex_joni> check dmesg
[11:12:50] <jthornton> ok
[11:13:00] <Valen> lo usually comes up first
[11:13:08] <alex_joni> dmesg | grep eth
[11:13:08] <alex_joni> [ 20.915516] eth0: VIA Rhine II at 0xfdffe000, 00:e0:4d:77:da:62, IRQ 19.
[11:13:14] <alex_joni> Valen: not on this 8.04
[11:13:27] <Valen> right you are
[11:14:01] <alex_joni> http://pastebin.ca/1559617 <- here's mine
[11:14:51] <jthornton> that looks similar to this computer but the other one only had the lo part
[11:15:03] <alex_joni> jthornton: then it didn't see the card
[11:15:11] <alex_joni> check dmesg | grep eth to see if it's trying at least
[11:15:15] <alex_joni> and then lspci -vv
[11:15:20] <jthornton> ok
[11:16:30] <jthornton> no eth in the dmesg
[11:17:36] <alex_joni> then check lspci
[11:17:56] <alex_joni> it looks like this for me:
[11:17:57] <alex_joni> 04:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
[11:18:22] <jthornton> nothing like that in mine
[11:18:31] <jthornton> * jthornton wonders what happened
[11:19:10] <alex_joni> maybe it doesn't sit properly
[11:19:14] <alex_joni> try reseating it
[11:19:42] <jthornton> ok I'll try that
[11:22:14] <Valen> pastebin the lspci
[11:22:27] <alex_joni> without network it's a bit harder ;)
[11:22:27] <jthornton> it is built in to the mother board
[11:22:35] <Valen> ahh yeah
[11:22:39] <Valen> true that lol
[11:22:46] <alex_joni> err.. hmm, then pastebin the lspci -vv
[11:22:47] <jthornton> thumb drives to the rescue
[11:22:50] <alex_joni> using a stick
[11:22:54] <alex_joni> right
[11:23:02] <Valen> I have been known to stick another NIC in to work out the problem with the first one ;->
[11:23:14] <jthornton> I'll put it back together first
[11:23:49] <Valen> meh if you feel like it ;->
[11:25:13] <skunkworks> disabled in the bios?
[11:27:25] <jthornton> I see MAC Lan = Auto in peripherals setup in bios
[11:28:15] <Valen> yeah thats fine
[11:28:32] <Valen> just so long as its enabled (which it would be unless you did something or updated the bios)
[11:28:41] <Valen> check with a different cable
[11:28:52] <jthornton> did that
[11:28:56] <Valen> I have seen some cards all of a sudden decide they don't like a paticular cable
[11:29:17] <jthornton> picky cards :)
[11:30:08] <Valen> and a VoIP phone
[11:30:59] <jthornton> now it won't boot up :(
[11:31:28] <jthornton> it gets to the ubuntu progress bar and then no signal
[11:32:41] <jthornton> dang gateway
[11:33:22] <archivist> skunkworks, what voltage does your drive go up to?
[11:33:49] <Valen> leave it for a while
[11:34:11] <Valen> it might be trying to sync time and it'll take ages to fail
[11:34:20] <jthornton> ok
[11:34:25] <Valen> (like 2 or 3 minutes or something silly)
[11:34:47] <Valen> did it stop in the bouncing progress bar phase or the progressing progress bar phase
[11:35:25] <jthornton> it looked like it finished the progress bars and the next screen would have been the desktop
[11:36:06] <Valen> whats on the screen now?
[11:36:18] <Valen> the time thing happens well before that
[11:36:30] <jthornton> just black
[11:37:09] <archivist> do the rescue boot
[11:37:09] <Valen> press ctrl + alt + F1
[11:37:16] <Valen> see if you get a terminal
[11:37:30] <jthornton> yes it wants me to log in
[11:37:47] <Valen> its something to do with X then
[11:39:32] <jthornton> it's been doing this off and on for a while
[11:39:58] <Valen> is the video on the motherboard?
[11:40:15] <Valen> if you login you can sudo poweroff to turn it off
[11:40:26] <jthornton> no it is a card
[11:41:20] <jthornton> ok I logged on
[11:41:41] <Valen> if you
[11:42:16] <Valen> tail /var/log/Xorg.0.log
[11:42:16] <Valen> It should tell you what went wrong with luck
[11:43:04] <jthornton> it complains that there is no such file
[11:43:33] <Valen> thats weird
[11:43:34] <Valen> try
[11:43:43] <Valen> sudo /etc/init.d/gdm restart
[11:44:34] <jthornton> went blank again
[11:45:02] <Valen> yeah it jumps you over to the graphical console (ctrl + alt + F7)
[11:45:15] <jthornton> did a ctrl alt f1 to get back
[11:45:17] <Valen> press ctrl + alt + F1 again to go back
[11:45:18] <Valen> yeah
[11:45:22] <Valen> then try the tail
[11:45:31] <Valen> of Xorg.0.log
[11:45:49] <jthornton> no file
[11:46:14] <Valen> thats really weird
[11:46:15] <jthornton> i'm in my home directory
[11:46:26] <Valen> yeah you did put the whole path in right?
[11:46:26] <alex_joni> jthornton: doesn't matter
[11:46:35] <Valen> try tail /var/log/syslog
[11:46:38] <alex_joni> if you do " tail /var/log/Xorg.0.log/
[11:46:39] <jthornton> yes
[11:46:41] <alex_joni> if you do " tail /var/log/Xorg.0.log"
[11:46:54] <jthornton> with the quotes?
[11:46:58] <Valen> no
[11:47:02] <alex_joni> no quotes
[11:47:47] <jthornton> syslog shows up
[11:48:21] <jthornton> now it worked
[11:49:01] <Valen> what worked?
[11:49:14] <jthornton> tail /var/log/Xorg.0.log
[11:49:17] <alex_joni> _it_ :D
[11:49:27] <jthornton> :)
[11:49:28] <alex_joni> jthornton: look for err lines
[11:49:44] <alex_joni> I think it's (ERR) or such at the beginning of the line
[11:49:56] <Valen> or something saying generally why its screwed
[11:50:19] <jthornton> server pid 4490 dead
[11:50:23] <Valen> If there isnt enough there you can do tail -n 100 /var/log/syslog | more
[11:50:26] <jthornton> dilled everything
[11:50:31] <Valen> whats the line above that?
[11:50:42] <skunkworks> archivist: bootstrap diodes are 200v - other than that.. the thrace isolation could be widened.
[11:50:52] <jthornton> that was at the top of the screen
[11:50:52] <skunkworks> thrace?
[11:50:54] <skunkworks> traces
[11:51:22] <archivist> skunkworks, I just got a lathe, it has a 180V 3.25A DC spindle motor
[11:51:45] <skunkworks> well - i have lightly tested it to 180v
[11:51:52] <skunkworks> 22a.
[11:52:58] <archivist> hmm which dir is the latest circuit?
[11:54:15] <skunkworks> hmm - can you get to my website?
[11:54:43] <archivist> I did the other day /me forgot the url though
[11:55:12] <skunkworks> I think it is http://electronicsam.com/images/KandT/servostart/schem/latestcurrentlimit
[11:55:14] <jthornton> didn't see anything in the syslog that jumped out at me
[11:55:32] <skunkworks> but it seems to be down here.
[11:56:12] <skunkworks> biab
[11:56:35] <archivist> skunkworks, and another famous site is dead /me wonders if a datacenter is dead somewhere
[12:03:39] <jthornton> yea, it came back alive
[12:06:44] <Valen> archivist http://downforeveryoneorjustme.com/
[12:08:27] <archivist> heh selling their service :)
[12:09:00] <archivist> sun's dns is dead
[12:09:02] <Valen> not me, I just thought it was cool
[12:09:07] <Valen> oooh thats gonna suck
[12:09:24] <archivist> yup its affecting mysql
[12:09:33] <Valen> damn sun for buying them
[12:09:40] <Valen> I'm gonna have to start using postgres now
[12:09:51] <archivist> and oracle for buying sun
[12:10:04] <archivist> noo use MariaDB
[12:10:38] <archivist> http://askmonty.org/wiki/index.php/Main_Page
[12:11:06] <archivist> Im running a buildbot for the project
[12:12:42] <Valen> mmm doesn't "feel" right those kind of forks
[12:12:51] <Valen> I spose it might have enough oomph behind it
[12:13:36] <Valen> I'm tempted to integrate SQL into my ultimate file system
[12:14:05] <archivist> Valen, that fork is monty the person who sold too sun
[12:15:06] <numen_> re
[12:15:34] <Valen> yeah but i dunno, forks are bad mmmkay
[12:16:06] <Valen> If he said, right dumping all mysql and starting over now we have learnt the lessons and can break compatibility
[12:16:08] <Valen> all for it
[12:16:29] <jthornton> gotta go thanks for the help
[12:16:30] <Valen> mysql is getting too big but not really featurefull
[12:16:31] <archivist> the Drizzle fork is more like that
[12:16:33] <Valen> no worries
[13:14:47] <Valen> http://www.fluid-forms.com/design-your-own/Earth-Brooch-Silver?lang=en
[13:16:09] <archivist> hmm have cnc ...profit!
[13:16:19] <Valen> they are 3d printed
[13:16:23] <Valen> out of silver
[13:16:49] <Valen> reckon .001mm is fine enough resolution to make something that detailed? assuming the right spindle
[13:27:45] <archivist> 1 thou probably good enough
[13:32:24] <Valen> probably need encoders on the motors to give EMC enough signal to work with
[13:37:42] <skunkworks> archivist: back up -http://electronicsam.com/images/KandT/servostart/schem/latestcurrentlimit/
[13:37:55] <skunkworks> sorry http://electronicsam.com/images/KandT/servostart/schem/latestcurrentlimit/
[13:38:01] <archivist> I just noticed :)
[13:38:36] <skunkworks> I thought I had let something expire - but suprisingly not.
[13:43:21] <archivist> I do that as well :)
[14:15:52] <twice2> i think i need to recompile kernel to enable certain options so atheros wifi driver will work.
[14:15:54] <twice2> is there specfic guide for doing this on emc2 system, or is even possible to do?
[14:16:19] <Valen> you can do so
[14:16:23] <Valen> I did it to enable SMP
[14:16:34] <Valen> I'll see if i can dig it up
[14:17:00] <Valen> see if this floats your boat
[14:17:01] <Valen> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Debian_Lenny_Compile_RTAI
[14:17:15] <Valen> I doubt you need to though
[14:17:24] <Valen> you using 8.04?
[14:17:34] <twice2> yes 8.04
[14:18:11] <Valen> atheros should work out of the box unless the devs turned something off
[14:18:24] <Valen> you might want to be wary of running a wifi card in it,
[14:18:47] <Valen> there might be dodgy latency issues, those drivers typically really aren't nice lol
[14:19:53] <twice2> not work out of box, even with restricted modules. i will work with ndiswrapper/window driver but causes latency prob
[14:20:50] <twice2> that's why i wanted to try native linux driver
[14:22:46] <twice2> Valen: thank you for your input tho
[14:22:55] <Valen> no worries
[16:28:31] <piasdom> anyone ever used one of these engravers ? http://www.engraving-machines-plus.com/Roland-EGX-600-PRO-Engraver_p_10.html?gclid=CLDTzf745JwCFcZM5QodWVcPGw
[16:29:18] <piasdom> it has servos on it and i was wondering if it's opssible for emc2 to control it
[16:29:34] <Jymm> for how much?
[16:30:07] <piasdom> Jymm:don't know what you're asking
[16:30:15] <piasdom> oooooooooooo
[16:30:29] <piasdom> you mean for me tp pay someone
[16:30:53] <piasdom> it's possible
[16:30:59] <piasdom> but around jan,
[16:31:00] <Jymm> piasdom: Well, you didn't just ask about that specific item at random, so you must of foudn one somewhere, how much are they asking for it?
[16:31:12] <piasdom> i have one
[16:31:23] <Jymm> and it doesn't work?
[16:31:25] <piasdom> but don't like their softare
[16:31:29] <Jymm> ah
[16:31:32] <piasdom> works great
[16:32:04] <Jymm> eah, it can be controlled via EMC, you might have to change out the controls/drivers though.
[16:32:17] <piasdom> on the machine ?
[16:32:23] <Jymm> no the frig
[16:32:52] <piasdom> guess this will be too hard for me....what's a frig ?
[16:33:03] <Jymm> ting you store food in to keep cold.
[16:33:09] <Jymm> thing
[16:33:13] <piasdom> ok
[16:33:33] <piasdom> i'm understanding you now.....smart :)
[16:33:53] <piasdom> Jymm; thanks
[16:34:03] <Jymm> Yes, the machine... you may have to remove the existing electronics in it and use "standard" controls and motor drivers.
[16:34:24] <piasdom> i'll look and see what they have
[16:34:54] <Jymm> You might want to see if they have a seperate spindle speed control and if you can reuse that.
[16:36:19] <piasdom> it has seperate controls for spindle and z
[16:37:17] <Jymm> cool, then you might be able to reverse engineer the existing Z motor driver.
[16:37:47] <Jymm> Else, just use something common like a gecko
[16:38:20] <fenn> can EMC run my refrigerator?
[16:38:33] <fenn> could one of the devs come install it for me?
[16:38:42] <fenn> it's urgent, plz
[16:38:44] <Jymm> fenn: ok course, you DO have the beer delivery attachement don't you?
[16:43:00] <piasdom> the board says it an XZ junction board...does this mean anything > A30C5 ?
[16:47:04] <piasdom> Jymm; thanks...gone searching
[16:49:00] <maddash> maddash is now known as evil_fluorine
[17:28:41] <piasdom> all i can find so far is the A30C5 is used(besides in this mach) to control TV AV input....is there a site to look for schematic ?
[17:30:55] <Jymm> You might be able to buy a service manual, but it might not be complete or even have schematics
[17:39:03] <piasdom> so i'll have to know what to do just by looking at the board ?
[17:39:40] <piasdom> i can make connector and cables(i'm contracted out to ITT)
[17:40:06] <Jymm> Rolnad stuff is usually very propritary
[17:41:12] <piasdom> thanks i'll go look some more
[17:41:12] <Jymm> I doubt you'll find anythng unless someone has already hacked one.
[17:41:45] <piasdom> which is better to use....which gecko ? or does in matter the mach
[17:42:36] <piasdom> i can afford any control, just want to get the best the first time
[17:42:39] <Jymm> You'll have to determine what motors are being used
[17:42:45] <piasdom> ok
[17:42:55] <Jymm> then select a driver to match
[17:44:31] <piasdom> thanks
[17:54:36] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[18:13:20] <piasdom> looks like roland scratched the brand off the servo
[18:14:50] <piasdom> does anyone reconize this > http://imagebin.ca/view/aHuhgQ.html
[18:17:54] <archivist> that motor looks a bit like a stepper with an encoder on it, could be some sort of ac servo
[18:19:08] <skunkworks> my guess would be ac (3phase) servo. does it cog when you turn it by hand?
[18:19:15] <piasdom> great....so it IS a stepper...they say servo :)
[18:19:35] <archivist> it has 8 wires as my motors do
[18:19:40] <piasdom> it's free when power off
[18:19:51] <skunkworks> then it is probably a servo...
[18:19:56] <archivist> servo then
[18:20:14] <piasdom> cool...my mill does cog
[18:20:28] <archivist> although my DC spindle motor cogs :)
[18:21:59] <skunkworks> archivist: going to build the amps?
[18:22:17] <archivist> may well do
[18:22:36] <archivist> or live with the scr drve thats in there
[18:22:37] <piasdom> so what would be a good control board ........ any suggestions ?
[18:22:39] <skunkworks> would love some feedback. (like - wth was he thinking... sort of things)
[18:22:51] <archivist> :)
[18:23:06] <skunkworks> piasdom: finding drives is going to be harder....
[18:23:23] <archivist> need to source parts this side of the pond
[18:23:29] <piasdom> thanks...then i'll stay where i'm at
[18:23:44] <piasdom> it was a thought
[18:27:34] <piasdom> digital ac servos....saw that ON the machine :) >need to have me eyes checked :)
[18:37:30] <Jymm> Is there a way to deterine it you have shitty stepper motors?
[18:37:51] <Jymm> without having a dyno that is
[18:39:00] <archivist> drive to specification curve with no load
[18:39:23] <Jymm> no torque curve available.
[18:39:27] <archivist> see how much past the curve you can get
[18:40:34] <archivist> get docs for a similar motor that does have curves
[18:40:36] <fenn> piasdom: looks like an AC servo to me
[18:40:44] <Jymm> like how do you tell if a stepper is going bad, besides the obvious.
[18:40:57] <Jymm> archivist: chna specials
[18:41:00] <Jymm> china
[18:41:04] <archivist> never had one die
[18:41:11] <fenn> red black white = three phase power, blue aqua pink yellow = hall effect sensors?
[18:41:24] <Jymm> Not die, but performance degraded.
[18:41:49] <Jymm> I was just curious is all
[18:42:13] <archivist> fault has always been in the driving or hardware never the motor
[18:52:38] <archivist> skunkworks, hmm the current drive is not dead :)
[18:53:40] <skunkworks> scr's - yeck ;)
[18:55:09] <archivist> its just that its not designed to be externally controlled, just a pot on the front panel
[19:03:28] <Skullworks> is that 8.04.1 LTS update safe or will it try to swap the Kernal?
[19:04:34] <skunkworks> Skullworks: !
[19:04:38] <piasdom> Skullworks; for EMC ?
[19:04:44] <Skullworks> Yazzum
[19:04:50] <Skullworks> yes
[19:05:26] <piasdom> Skullworks; don't know what Yazzam is but i have 8.04 running EMC2
[19:06:14] <skunkworks> Depends - if you installed it from the livecd - or removed the normal kernal - you will probably be fine. If you didn't - it may make the normal kernal active again. But a little bit if editing fixes that. (atleast that is what is in my memory warehouse)
[19:07:12] <piasdom> i did the live cd...and had to tweek the config(with these peoples' help
[19:07:17] <piasdom> )
[19:08:09] <piasdom> but jepler(or someone) put in sample configs that works
[19:08:29] <Skullworks> My update manager shows a 8.04.1 LTS update - I know 8.10 or later breaks things - replaces the RTAI kernel but not sure what this LTS update does.
[19:08:29] <piasdom> i have a sherline mill
[19:09:27] <piasdom> Skullworks; so you have 8.04 now ?
[19:09:40] <Skullworks> Though I do have SIM installed and running on my Eeepc 900a with Eeebuntu v8.10
[19:09:42] <Skullworks> yes
[19:10:03] <Skullworks> from live CD for v2.2.x
[19:10:38] <piasdom> i always run update(though i don't think we have the same source)
[19:11:15] <piasdom> my live cd was with 2.0...something...it's been awhile
[19:11:59] <piasdom> i HAD debian to start with
[19:13:04] <Skullworks> On the dummy boxes I keep forgetting my pass - so I load the latest live CD.
[19:13:41] <piasdom> but no matter what i(we)say here..the decision is yours' to make
[19:14:06] <piasdom> all i can do is let you know what i did
[19:14:24] <Skullworks> The box doing the work is in an out building - only wireless out there - and no v8.04 driver support for the hardware I have :(
[19:15:08] <piasdom> and i'll help all i can(not saying much:)
[19:15:19] <piasdom> what you trying to get done ?
[19:16:28] <Skullworks> no big - I'll just change repositories and get v2.3.3 and worry about the rest of the Ubuntu install later.
[19:16:39] <piasdom> cool
[19:46:05] <piasdom> once again.....where's the manual for hal......i want to learn somein
[19:47:53] <piasdom> want to look over it this weekend
[19:58:31] <jepler> http://linuxcnc.org/docview/
[20:00:28] <piasdom> jepler;Thanks
[21:09:03] <ZeroFlex_afk> hellow, good evening
[21:21:46] <toastydeath> so question re: college
[21:22:15] <toastydeath> i am going to apply to transfer into a physics program, 90 credits for a b.s., then 60 credits to a b.e. in mech. e.
[21:22:33] <toastydeath> should I stay the extra year in physics to take the senior level classes
[21:24:05] <ZeroFlex_afk> does anyone in here know something about these servo's ? 1FT 5064-OAG01-2-Z from siemens
[21:24:14] <ZeroFlex_afk> i can buy 3 of them
[21:43:18] <ZeroFlex_afk> but i cant find anything on the net (specs) about them
[21:53:50] <micges> ZeroFlex_afk: ask them via email
[21:55:07] <ZeroFlex_afk> i did, he didnt know, told me to search on the net....
[21:56:04] <micges> ask siemens
[21:56:06] <ZeroFlex_afk> what values (nm) do i need for a retrofit on a mil like the deckel fp2 (mine wil be sort of the same)
[21:56:35] <ZeroFlex_afk> ok
[21:56:45] <ZeroFlex_afk> will email them
[21:57:05] <micges> search the web, there are some programs to calculate needed Nm
[21:58:06] <micges> you enter vel, acc, mass and such and you get ~Nm
[22:00:57] <ZeroFlex_afk> would it be bad if i oversized the motors ?
[22:01:42] <archivist> by how much
[22:02:00] <ZeroFlex_afk> haha
[22:02:11] <archivist> just odd trade offs may bite
[22:02:16] <ZeroFlex_afk> ok, need to find out what the mass is
[22:02:23] <ZeroFlex_afk> :) then calculate
[22:02:28] <archivist> max rpm is lower on larger motors
[22:02:29] <Skullworks> Toasty taking Physics - Next he will be saying "The Earth doesn't hold me down, I hold the Earth up!"
[22:02:42] <ZeroFlex_afk> hmm
[22:03:53] <BigJohnT> logger_emc:bookmark
[22:03:53] <BigJohnT> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-09-09.txt
[22:04:28] <ZeroFlex_afk> i'm searching all the spare time i have on the internet to simular mill's that have been retrofitted but cant find one with servo's and servo specifications with it.
[22:04:50] <ZeroFlex_afk> if they use steppers it is an 12nm stepper
[22:04:57] <BigJohnT> BigJohnT is now known as BJT_Shop
[22:09:56] <BJT_Shop> * BJT_Shop has internet in the shop now, don't know how I fit the hub in there but no more lugging the plasma computer to the beer cave for updates :)
[22:10:31] <alex_joni> nice
[22:10:42] <alex_joni> managed to sort out that NIC issue?
[22:12:38] <alex_joni> * alex_joni is off to bed
[22:12:45] <alex_joni> good night all

[22:53:46] <dmess> hi all
[23:04:52] <fenn> plasma table design, (not mine) request for comments: http://openfarmtech.org/weblog/?p=1048
[23:07:16] <fenn> er, this page actually has the goods http://openfarmtech.org/index.php?title=Torch_Table_Build
[23:24:09] <skunkworks> fenn: what do you think of stirling engines?
[23:36:16] <fenn> skunkworks: i think they couldnt possibly work :)
[23:36:48] <fenn> "runs on hot air" can you believe it?
[23:37:12] <Jymm> Yes, many women run on hot wire, why not an engine.
[23:37:17] <fenn> reminds me of http://blog.makezine.com/archive/2009/09/claims_of_pnuematic_processor_full.html
[23:39:23] <skunkworks> heh
[23:43:32] <fenn> the water cylinder stirling is interesting
[23:44:01] <fenn> erm. "liquid piston"
[23:44:42] <MarkusBec> MarkusBec is now known as MarkusBec_away
[23:47:43] <fenn> apparently you can run stirlings in reverse to make liquid helium
[23:49:26] <fenn> aha this is what i was thinking http://www.bekkoame.ne.jp/~khirata/seesaw/indexe.htm
[23:51:16] <skunkworks> couple of pretty good articles
