[02:15:43] <TekniQue> is that a lathe?
[02:16:28] <skunkworks> no - large vmc
[02:16:31] <skunkworks> *hmc
[02:16:43] <skunkworks> that is for rigid tapping
[02:18:09] <TekniQue> ah
[02:19:54] <skunkworks> http://www.electronicsam.com/images/KandT/oldkandt.JPG
[02:23:23] <jmkasunich> gonna do rigid tapping on that beast sam?
[02:24:30] <skunkworks> jmkasunich: Hey! yes - that is the plan.
[02:24:49] <jmkasunich> 1" x 8tpi :-)
[02:25:01] <skunkworks> yes - I plan on making a video :)
[02:25:07] <jmkasunich> I wanna see it do #2-56
[02:25:29] <skunkworks> we can try :)
[02:25:54] <jmkasunich> I just updated my website for the first time in almost 2 years
[02:26:02] <jmkasunich> now if I can just get going on all my other projects
[02:27:08] <skunkworks> heh - I check every so often just to see.
[02:27:23] <jmkasunich> nothing shop related, just some photos
[02:27:33] <skunkworks> nice though
[02:28:01] <jmkasunich> http://jmkasunich.com/cgi-bin/blosxom/index.html
[02:28:44] <skunkworks> I think the spindle encoder is the last major mechanical change to the machine. Now it is just debugging (well and a control panel)
[02:28:59] <jmkasunich> most impressive
[02:29:13] <skunkworks> jmkasunich: cool pics
[02:29:24] <jmkasunich> thanks
[02:29:50] <skunkworks> all I have is http://www.electronicsam.com/images/house/IMG_1525.JPG
[02:30:12] <jmkasunich> nice
[02:30:23] <jmkasunich> looks like you got a bit more snow that we have
[02:30:49] <skunkworks> almost 24"
[02:31:17] <jmkasunich> we have maybe 6-8, where is isn't drifted
[02:31:32] <jmkasunich> had a ton of wind, some places are completely clear, others are deep
[02:31:56] <jmkasunich> is your garage all done?
[02:32:01] <skunkworks> we got some pretty strong winds too.
[02:32:43] <skunkworks> it is functional.. (garage doors work and such) but it needs wiring - outlets and light. (we just use the opener light right now_
[02:33:00] <jmkasunich> thats a summer project, or as least spring
[02:33:04] <skunkworks> yes
[02:33:21] <skunkworks> although it has been a couple of summers and springs so far ;)
[02:33:34] <jmkasunich> I guess I have been away for a while
[02:33:50] <skunkworks> yes you have! glad your back :)
[02:34:06] <jmkasunich> not sure how back I am
[02:34:13] <skunkworks> have you seen any of the videos?
[02:34:25] <jmkasunich> me in the basement and the new dog loose upstairs might result in problems
[02:34:35] <jmkasunich> yes, I've been keeping up on the mailing list
[02:34:53] <skunkworks> heh - good.
[02:35:36] <skunkworks> had a little step back today as I had deleted a abs.0 from a thread and it took a bit to figure out what was going on ;)
[02:35:52] <skunkworks> (spindle quite working)
[02:36:24] <jmkasunich> not quite working
[02:36:33] <skunkworks> *quit
[02:36:37] <skunkworks> heh
[02:36:51] <skunkworks> well - I have to get going - good to talk to you!
[02:37:12] <jmkasunich> same here
[02:37:16] <skunkworks> bbl
[04:29:44] <Connor> http://www.vhipe.com/product-private/SuperPID.htm
[04:30:18] <Connor> Been looking at that for a while now.. trying to figure out what OPTO's he's used on it.. I want something like that, except, just the AC side of it.. no need for the micro.
[04:30:27] <Connor> anyone here have one of them ?
[04:44:35] <Connor> anyone ?
[04:57:43] <atmega> You are no longer limited to burning wood and melting plastic
[04:57:53] <atmega> sounds familiar
[04:59:06] <Connor> Yea. I'm hoping someone who has one can tell me the #'s on the two optos..
[10:41:40] <Jymmm> cradek: I thought you might be interested in this... TTF2SVG http://xmlgraphics.apache.org/batik/tools/font-converter.html
[18:58:17] <Albert_N3> where lookahead code calculated on emc2 source code?
[19:00:18] <archivist> you probably want to look at the trajectory planner
[19:00:30] <awallin> Albert_N3: try this http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Simple_Tp_Notes
[19:01:01] <awallin> and here http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TrajectoryControl
[19:02:17] <Albert_N3> thanks
[19:06:48] <Albert_N3> lot of love...
[19:06:56] <Albert_N3> ...
[19:07:09] <Albert_N3> lol
[19:08:48] <awallin> Albert_N3: improving lookahead isn't a simple thing to do...
[19:09:27] <Albert_N3> yeah, you bet. but maybe...
[19:25:53] <Jymmm> car bowling... http://www.cnn.com/video/#/video/us/2010/12/19/wa.ice.sliding.cars.khq?hpt=C2
[19:26:35] <Albert_N3> ...how can i made livecd of emc2 ?
[19:27:02] <awallin> there should be an iso-download somewhere
[19:27:31] <awallin> http://www.linuxcnc.org/lucid/ubuntu-10.04-linuxcnc1-i386.iso
[19:27:35] <Jymmm> Be sure to verify the MD5 and burn at 4x speed.
[19:27:54] <Jymmm> or slower
[19:28:25] <archivist> I have never burnt that slow for yonks
[19:28:41] <Jymmm> "yonks" ?
[19:28:53] <archivist> good cd's and good drive will be happy a lot faster
[19:29:18] <archivist> yonks...longer that I can remember ish
[19:29:25] <Albert_N3> can i run livecd without hardisk at all?
[19:29:37] <Jymmm> archivist: The problem is that for years emc iso have issues for some, and the solution is to burn at 4x resolves the issue
[19:29:59] <psha> Albert_N3: yes
[19:30:18] <psha> hard disk is not required unless you want some presistance of configs/user dta
[19:30:19] <psha> data
[19:30:21] <Jymmm> archivist: I have no idea what the issue is, but that's the anti-coaster solution.
[19:31:17] <Albert_N3> whats is minimum RAM to run livecd?
[19:31:50] <Jymmm> 256 and the VERY min, 512 ok, more is better
[19:32:55] <Albert_N3> thanks! :)
[19:32:59] <Jymmm> Albert_N3: When you use a LiveCD, everything is kept in memory and not cached to hdd, so the more ram the better, or it'll be reading the cd a LOT
[19:33:16] <Jymmm> and cd/dvd are very slow
[19:33:44] <Albert_N3> how much is LOT of RAM? recommended?
[19:34:34] <Albert_N3> more Ram recommended?
[19:35:06] <motioncontrol> good evening, i have add a new hal pin out, and write in interp_queue.hh the new fuction, but when compile have :../lib/librs274.so.0: undefined reference to `SP_ON()'
[19:35:06] <motioncontrol> collect2: ld returned 1 exit status
[19:35:06] <motioncontrol> make: *** [../bin/rs274] Errore 1
[19:35:06] <motioncontrol> . where is the problem ?
[19:36:33] <psha> Albert_N3: 1gb is enought
[19:37:15] <psha> Albert_N3: less then 512 will involve much CD reading
[19:37:38] <Albert_N3> ok!
[19:38:15] <psha> also i think it's better to use usb stick instead of CD
[19:38:16] <Jymmm> There is never enough ram or L2 cache.... 4TB Ram, 512GB L2 Cache, and 512 PB Storage
[19:38:56] <Jymmm> psha: Eh, both are slow, thumbstick slightly faster.
[19:39:12] <Albert_N3> i have 2GB... it would be enough Thanks!!!
[19:39:15] <psha> Jymmm: re:car bowling: heh, use winter tires :)
[19:39:15] <Albert_N3> :)
[19:39:48] <Jymmm> Albert_N3: that's plenty unless you get abusive and run 100 apps at once
[19:39:58] <psha> Jymmm: cd is extremly slow on random reads and needs spinup time...
[19:41:37] <Jymmm> LiveCD's are great, just netbooting is better if it's going to be used on a regular basis
[19:42:46] <Jymmm> psha: I'm from California dude, we have no funky white stuff =)
[19:42:56] <Jymmm> on the ground that is
[19:43:06] <Albert_N3> 2GB is good right?
[19:43:17] <Jymmm> Albert_N3: excellent, more than enough
[19:43:32] <Albert_N3> ^_^
[19:43:38] <Albert_N3> thanks!
[19:44:14] <Jymmm> Albert_N3: Be sure to run latency tests for 24hours too
[19:44:28] <Albert_N3> how to do thats?
[19:44:30] <Jymmm> to be on the safe side.
[19:45:00] <Jymmm> Well, get up and going on the livecd first, then somene can give you a hand with that
[19:45:04] <Albert_N3> for rtai setting
[19:45:56] <Albert_N3> (i am still downloading a new emc2 livecd)
[19:46:06] <Albert_N3> ok.
[19:46:24] <psha> Jymmm: every year there are new videos from Vladivostok (it's near Japan) where 4x4 cars with winter tires play same bowling :)
[19:46:43] <Jymmm> Albert_N3: Burn it at 4x speed to save some grief.
[19:47:15] <Jymmm> psha: I bet everywhere has that. should have a 360 8" rubber bumper =)
[19:47:29] <Albert_N3> ok Jymmm i will do that.
[19:49:31] <Albert_N3> i ll do a very deep mark on the CD.
[19:49:46] <psha> Jymmm: it's not strange in places where people have snow once per 10 years, but in places where 6 months are covered with ice/snow its a bit strange :)
[19:49:57] <Albert_N3> and run latency test
[19:50:37] <Albert_N3> snow is good!
[19:57:04] <Albert_N3> if i have old livecd, can i update it? recompile emc2? how?
[19:57:38] <Albert_N3> its a big .iso
[19:57:46] <awallin> you can also do a standard 10.04lts install, and then run the emc2-install script
[19:58:02] <awallin> the old livecd is probably not a good idea...
[19:58:54] <Albert_N3> why not good idea?
[19:59:40] <Albert_N3> ubuntu it self has updated version also?
[20:00:25] <Farthen> andypugh: i have found the problem from yesterday with my random behavior of the y axis: one cable was loose and fell off -.-
[20:00:29] <awallin> if it's a livecd based on 10.04lts then maybe it will work. just upgrade to the latest emc2 when done
[20:02:40] <Albert_N3> http://www.linuxcnc.org/lucid/ubuntu-10.04-linuxcnc1-i386.iso-->is this based on 10.04lts
[20:02:43] <Albert_N3> ?
[20:03:10] <awallin> yes
[20:03:53] <Albert_N3> i might need an update in the future, i should get prepare.
[20:04:53] <isssy> hi mic
[20:05:29] <andypugh> Farthen: I think I suggested that possibility?
[20:21:50] <Albert_N3> now ubuntu is v10.10
[20:22:08] <Albert_N3> but no prblem
[20:22:27] <Albert_N3> it is still the same lts
[20:27:47] <Albert_N3> if i add 2gb more RAM, so it is 4gb of RAM, will ubuntu-10.04 recognize it? or it will recognize it as 3.1gb?
[20:31:18] <andypugh> EMC2 doesn't need much memory.
[20:34:34] <Albert_N3> i see.
[20:35:03] <Albert_N3> i just worry about rtai
[20:38:36] <Albert_N3> ok i just read http://en.wikipedia.org/wiki/List_of_Ubuntu_releases
[20:39:26] <Albert_N3> i understand now
[20:39:43] <Albert_N3> thanks again!
[20:39:53] <Albert_N3> have a nice day.
[21:23:46] <tomaw_> [Global Notice] Hi, sorry for the noise. A quick be of re-routing due to the issues a few days ago and some upcoming server maintenance.
[23:49:51] <mikegg> what sorts of things could cause EMC2 to turn off, but not throw an error ?
[23:51:56] <Valen> M2 ?
[23:53:24] <mikegg> that would be lovely if it were that simple...
[23:59:45] <andypugh> It probably thinks it has finished, I guess the question is why it thinks that.
