[04:36:45] <NTU> cradek: perfect response xD
[05:54:39] <skunkworks_> https://groups.google.com/forum/#!topic/machinekit/SMdbuf4b5LI
[07:53:50] <jepler> great, now d.a. is yelling at me.
[07:54:31] <jepler> I knew I should have kept my trap shut, but noooo
[08:07:15] <cradek> his tantrums are not very endearing
[08:08:53] <jepler> I can vaguely imagine his situation
[08:09:02] <jepler> there's some russian linuxcnc forum where they use rar as a matter of national pride
[08:09:10] <jepler> and all he wanted to do was copy this blob of dubious provenance onto our forum
[08:09:13] <jepler> or whatever
[08:09:15] <archivist> the middle ground is zip, iirc rar is only 10-20% of the windows market
[08:11:31] <jepler> do you think responding to him with sarcasm is a good idea?
[08:12:03] <archivist> no, he has been helpful in irc
[08:13:50] <archivist> grmble, why is halmeter one variable at a time :)
[08:17:26] <jepler> this is -devel, go write code
[08:17:45] <archivist> that is sarcasm!
[08:21:02] <jepler> I only have your word for that
[08:32:18] <cradek> welp, now EBo's on it
[08:37:40] <cradek> archivist: halshow is not as pretty, but its "watch" thing will show you a list of hal things
[08:40:21] <archivist> I am trying to debug the hobbing machine I am converting, getting a helix instead of a spur, about 1 deg error, it could be a duff hob dragging the plastic around, so far I cannot see any lcnc error
[08:40:53] <cradek> ooh, do you have photos of it?
[08:42:02] <archivist> up to a year ago http://www.archivist.info/cnc/hob2/ with some added goodness http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_17_Barber_Colman_cnc/
[08:42:52] <archivist> but yesterday the vfd I put on died, fitted another and cant see where the bug is yet
[08:44:37] <archivist> or I simply set the hob angle incorrectly (hob does not state its lead angle like it should)
[08:44:49] <cradek> the path for the cutting oil return is very graceful
[08:44:56] <cradek> oops brb
[08:46:51] <archivist> that is a part catching entry, should have a basket below
[09:25:26] <cradek> huh, I saw a nozzle on top and assumed it was for oil
[09:25:57] <cradek> so you removed a gearbox? anything else?
[10:06:23] <pcw_home> is there a preemt-rt kernel available as a package for wheezy?
[10:07:14] <seb_kuzminsky> pcw_home: yes
[10:07:41] <seb_kuzminsky> it's called linux-image-$VERSION-rt-$ARCH
[10:07:51] <seb_kuzminsky> linux-image-3.2.0-4-rt-amd64 - Linux 3.2 for 64-bit PCs, PREEMPT_RT
[10:08:10] <seb_kuzminsky> it's in the debian.org archive, available to anyone
[10:09:58] <pcw_home> OK thanks, someone on the forum having troubles (somewhat expected) getting a mesa Ethernet hm2 card to work
[10:10:47] <pcw_home> so
[10:10:49] <pcw_home> sudo apt get install linux-image-3.2.0-4-rt-amd64
[10:10:50] <pcw_home> ?
[10:13:09] <seb_kuzminsky> that should do it
[10:14:03] <pcw_home> Thanks, that seems the easiest path
[10:31:00] <archivist> cradek, yes the spout is the cutter oil supply, I thought your comment was about the open v below
[10:31:59] <archivist> cradek, removed the mechanical auto stuff (magazine feed mechanism)
[10:37:44] <seb_kuzminsky> it's depressing when i go to work on a patchset-in-progress and i see original commit dates from months and months ago :-/
[12:22:03] <skunkworks> who is david a on irc?
[12:26:26] <skunkworks> archivist, we need a video of it running.... please :)
[12:26:44] <archivist> cncbasher on ird
[12:26:48] * skunkworks things gear hobbing is cool...
[12:27:07] <archivist> skunkworks, buy me a camera then :)
[12:27:29] <skunkworks> I know for a fact you used to have usb camera.... (didn't you?_
[12:27:47] <archivist> hmmm, mebe
[12:27:56] <archivist> forgot about that
[12:29:11] <skunkworks> I have talked to cncbasher - he seems nice.
[12:32:07] * skunkworks has a thing for gear hobbers.. for some reason..
[12:32:43] <pcw_home> bad day maybe (I hate rar its always a pita)
[12:33:49] <skunkworks> I hate rar also...
[12:34:31] <archivist> I hate it when a machine is not quite right....
[12:34:48] <archivist> is my maffffs wrong
[12:56:54] <skunkworks> pcw_home, I have use the wheezy+rtprempt
[12:57:06] <skunkworks> pretty painless
[12:57:53] <pcw_home> I need to try that but have been unable to get a machine that will boot from a hybrid USB stick
[12:58:46] <skunkworks> if you have those GB motherboards - they won't because the rtai kernel doesn't see the usb..
[12:59:01] <skunkworks> I think we have had this conversation :)
[12:59:56] <pcw_home> I cant get it to boot on a D525 either, and yes we've been through this
[13:01:44] <skunkworks> I have had it boot on an older atom.
[13:02:09] <skunkworks> pcw_home, are you creating the usb stick using DD?
[13:02:18] <pcw_home> Yes, dd
[13:02:22] <skunkworks> huh
[13:03:35] <pcw_home> files and file checksums seemed right
[13:14:36] <KGB-linuxcnc> 03Dewey Garrett 05master d22216d 06linuxcnc 10src/emc/usr_intf/emcsh.cc 10src/emc/usr_intf/shcom.cc 10src/emc/usr_intf/shcom.hh emcsh: support rapid_override * 14http://git.linuxcnc.org/?p=linuxcnc.git;a=commitdiff;h=d22216d
[13:23:32] <cradek> cool
[13:26:08] <kwallace> This looks interesting (Olimex A13 SoM): http://www.ebay.com/itm/271542660637
[13:28:22] <kwallace> https://www.olimex.com/wiki/A13-SOM
[13:44:38] <seb_kuzminsky> it's very silly that emcsh's feed_override and rapid_override take a percentage as int, then divide it by 100.0 to get a float multiplier to send to the controller
[13:45:37] <cradek> all the guis pretty much do the equivalent
[14:51:58] <CaptHindsight> kwallace: linuxcnc runs on the A13, there's just no real time IO yet, same for the A20 boards
[14:56:57] <CaptHindsight> kwallace: about the same price but dual core and 1GB DDR http://store.cutedigi.com/pcduino3-nano/
[15:06:55] <kwallace> CaptHindsight, Oh shoot, you posted that link before and I forgot. My application (sprinkler, thermostat and others) needs a dirt cheap Linux processor with Ethernet and can be headless. I ordered a Raspberry Pi, then found this: http://www.ebay.com/itm/290948287064 and started to consider other options such as: https://www.olimex.com/Products/OLinuXino/iMX233/iMX233-OLinuXino-NANO/open-source-hardware .
[15:17:11] <kwallace> Oops again, I did an Andy and just bought a pcDuino.
[15:18:17] <kwallace> by mistake
[15:20:45] <kwallace> Way off topic: http://www.amnh.org/explore/news-blogs/research-posts/hints-of-gravitational-waves-in-the-stars
[19:44:18] <PCW> well latest master breaks hm2_eth in some way sigh
[19:52:39] <jepler> PCW: I'll look into it
[19:52:45] <jepler> PCW: just basic loading, or something else?
[20:01:19] <jepler> PCW: I didn't see a problem loading hm2_eth at d22216d, using my same old 7i80 card as always, on an amd64 debian7 desktop
[22:09:46] <skunkworks_> pcw is probably doing something wrong.. ;)
[22:10:08] <skunkworks_> what is it doing? I can test my 7i80 tomorrow
[22:52:40] <pcw_home> I get "resource temporarily unavailable" and lose Ethernet connectivity
[22:54:32] <pcw_home> never saw this before last pull (I guess it could be a hardware problem though a different MB behaves the same)
[22:55:06] <pcw_home> I'll have more time to poke at it tomorrow
[23:04:32] <pcw_home> (runs for a minute or so before blowing up)
