[00:00:00] <iwoj> freeeeeze
[00:00:01] * pfred1 runs EMC on a 1 GHz P3
[00:00:08] <iwoj> with 30000
[00:00:16] <iwoj> ns
[00:00:22] <gene__> Thats pushung that 1Ghz cpu
[00:00:27] <pfred1> you have ot look in syslog
[00:00:39] <pfred1> gene__ I know it limits what i can do
[00:01:05] <pfred1> gene__ but for a machine i literally picked out of a trash pile I think it does pretty good :)
[00:01:35] <pfred1> I been looking at atom systems i hear they're da bomb for latency
[00:01:49] <pfred1> like 5000ns

[00:04:11] -!- theorbtwo has quit [Ping timeout: 252 seconds]
[00:04:18] theorb is now known as theorbtwo
[00:04:54] <pfred1> hmm a game of mines or KMahjongg?
[00:06:14] <iwoj> there's a conf file in /etc/modprobe/emc2 with a parport_pc line
[00:06:58] <iwoj> it says something about uncommenting it so that other programs don't interfere with the parallel port
[00:07:15] -!- cevad [cevad!~davec@host-174-45-229-40.bln-mt.client.bresnan.net] has joined #linuxcnc
[00:07:38] <pfred1> iwoj have you looked in syslog to see if it says what might have crashed your system?
[00:07:53] -!- rob_h has quit [Ping timeout: 244 seconds]
[00:08:49] <iwoj> BINGO!
[00:08:52] <iwoj> That was it.
[00:09:19] <iwoj> now I'm testing the x-axis and my multi meter is showing a voltage change from 0.02V to 0.2V
[00:09:23] <iwoj> great!
[00:09:46] <pfred1> try testing the direction pin
[00:09:47] <iwoj> I had installed some modprobe stuff that was using the pport
[00:09:50] <pfred1> it should be easier to see
[00:09:55] <iwoj> will do
[00:10:17] <pfred1> yeah I didn't think emc liked the regular port driver loaded
[00:10:43] <iwoj> awesome
[00:11:03] <iwoj> xdir goes from 0.02V to 5.0V
[00:11:06] <pfred1> now yo ucan crank your base period back up
[00:11:19] <iwoj> beuaty.
[00:11:21] <pfred1> or down rather
[00:11:22] <iwoj> beauty.
[00:11:31] <iwoj> thanks guys
[00:11:39] <pfred1> thank yourself you did it
[00:11:39] <iwoj> i've got to run, but you've been a huge help.
[00:12:02] * pfred1 wants to get on the leader board today in KMahjongg
[00:12:27] <pfred1> I have to beat 05:47
[00:12:28] <iwoj> it always helps to share the troubleshooting with others. i learned a lot in the procees.
[00:12:30] <iwoj> later.

[02:36:24] <gene76> <cradek> The newest that I just installed 2 hours ago is crashing the machine on quit, about every third time.
[02:36:27] -!- Tom_L [Tom_L!~Tl@unaffiliated/toml/x-013812] has joined #linuxcnc
[02:37:14] <gene76> <pfred1> that is what I am getting by using this script to run it.
[02:37:22] <pfred1> gene76 most clients won't highlight a user if you enclose their nick in brackets
[02:37:41] <jdhNC> and it looks like you are cut/pasteing
[02:38:16] <pfred1> jdhNC well if you know how to do it you can snag the nick easily without the brackets double click it nets the word in X
[02:38:45] <gene76> No, just copying. Anyway this script, if used to run latency-test instaed of linuxcnc, will get that figure
[02:38:51] <gene76> #!/bin/bash
[02:38:52] <gene76> taskset 0x00000002 /usr/bin/linuxcnc -l &
[02:38:54] <gene76> exit 0
[02:38:55] <gene76> gene@shop:~/linuxcnc/configs/my-mill-atom$
[02:39:06] <gene76> ignore last line
[02:39:33] <gene76> so how do i send a line to pfred1?
[02:39:50] <pfred1> /msg pfred1 would send a private message
[02:40:08] <pfred1> but to highlight in most clients in a channel just begin the line with the nickname
[02:40:11] <gene76> not private mode
[02:40:20] <pfred1> gene76 like this
[02:40:36] <gene76> so everyone see it, but pfred1 sees that it is addressed to him?
[02:40:56] <pfred1> yeah it'd be yellow in my client as opposed to white on a black background
[02:41:02] <gene76> pfred1 like this?
[02:41:07] <pfred1> yes
[02:41:16] <gene76> ahh, thanks
[02:41:28] <pfred1> and if I'm in another window it'll show up as a red activity for the window
[02:41:57] <pfred1> I think that is how a lot of IRC clients work
[02:41:57] <gene76> pfred1 I've seen that, wondered where it came from
[02:42:12] <pfred1> now you know
[02:42:14] <gene76> pfred1 I dare say most
[02:42:53] * pfred1 has been IRCing in some form or another since 1995 so has picked up a thing or two ...
[02:43:15] <pfred1> that is a /me BTW
[02:43:17] <gene76> anyone, in eagle, how do I put text that isn't "isolated" just carved once
[02:43:57] <pfred1> as in cadsoft Eagle?
[02:44:23] <gene76> Its over carving it when I put it in the top or bottom layers, cadsoft eagle yes, followed by pcbgcode
[02:44:59] <gene76> I am getting a .txt file but its esswentially empty
[02:45:02] <pfred1> I keep hoping for an FOSS replacement for Eagle
[02:45:23] <gene76> so do I, & gEDA isn't it.
[02:45:32] <pfred1> not yet for me either
[02:45:43] <pfred1> though I've seen some folks do some impressive stuff with it
[02:45:51] <pfred1> it just crashes a lot for me
[02:46:54] <gene76> I'm about shot for the night, so I'll go in & check my email & ultra lite supply. :) Back at it tomorrow
[02:47:07] <pfred1> I have the freebie Eagle and once i thought I needed a bit more board real estate so I exported parts of my circuit to images and pasted them together in the gimp
[02:47:23] <pfred1> it is a bit of a pain but can be made to work :)
[02:47:41] <pfred1> I eventually redesigned the board so it fit in the limited space
[02:49:20] <pfred1> really eagle's 3x5 freebie limit just forces me to design better boards
[02:50:04] <pfred1> because i really don't want to make boards any bigger than that if I can help it anyways
[02:50:19] <jdhNC> you could join two with headers if you really needed the space.
[02:50:46] <pfred1> yes make a project with modules
[02:50:59] <pfred1> something i naturally do anyways
[02:52:11] <Tom_L> gene76, not sure what you're asking
[02:52:49] <Tom_L> maybe vector is your answer?
[02:52:57] <pfred1> this was the stitched together board I made with freebie eagle http://img404.imageshack.us/img404/6325/stitched.png
[02:53:33] <Tom_L> still got airwires too
[02:53:50] <pfred1> Tom_L I never planned on etching it
[02:54:07] <Tom_L> why not?
[02:54:23] <pfred1> no setup right now
[02:54:27] <pfred1> http://img717.imageshack.us/img717/8530/pict0787a.jpg
[02:54:56] <Tom_L> classic
[02:55:07] <pfred1> but i still print it out as a drill guide
[02:55:23] <pfred1> looks OK from the top http://img697.imageshack.us/img697/7711/pict0789w.jpg
[02:55:39] <Tom_L> yep
[02:56:00] <pfred1> believe me just having a drill guide is pretty handy for making a board
[02:57:10] <pfred1> that is this http://img692.imageshack.us/img692/646/hsoptos.png
[02:57:33] <pfred1> works good too ;)
[02:57:47] <Tom_L> i've been using eagle quite a while
[02:57:56] <pfred1> its what i use
[02:58:08] <pfred1> I keep trying the FOSS stuff but so far no luck with it
[02:58:11] <Tom_L> and etch once in a while but mostly just have em done anymore
[02:58:37] <pfred1> I was etching but PNP blue screwed up 2 toner cartriges on me
[02:58:46] <pfred1> be cheaper for me to have them done
[02:58:49] <Tom_L> i didn't like that stuff
[02:58:58] <Tom_L> i have a packet of it still
[02:59:08] <pfred1> well having messed up $300 in toner carts I'm not too thrilled with it myself
[02:59:26] <Tom_L> i use a laserjet that cost me $65 new
[02:59:37] <Tom_L> the replacement cartridge costs more than the printer
[02:59:48] <pfred1> yeah they come with half fills
[02:59:54] <Tom_L> i used a series II until it died
[03:00:11] <jdhNC> heh, I've never seen a II die
[03:00:23] <pfred1> I have a 4+
[03:00:46] <Tom_L> i forget what happened to it
[03:00:54] <Tom_L> i probably could have fixed it but meh
[03:01:19] <pfred1> I hate inkjets whenever i go to use one the ink is always clogged
[03:03:29] <jdhNC> or it's doing a cleaning cycle and dumping all the ink in a sponge
[03:03:43] <pfred1> Tom_L this has a lot of air wires http://img545.imageshack.us/img545/2833/tb6560ahqacr.png
[03:03:44] <Tom_L> yeah
[03:04:14] <Tom_L> i'm not used to making boards with lots of space between parts :)
[03:04:46] <pfred1> jdhNC ever seen the video about The Light Bulb Conspiracy?
[03:04:52] <Tom_L> http://tom-itx.dyndns.org:81/~webpage/boards/USBTiny_Mkii/USBTinyMkII_1-1c_top.jpg
[03:04:58] <Tom_L> i just got those back last week
[03:05:06] <Tom_L> and assembled a batch last night
[03:05:13] <jdhNC> nope
[03:05:23] <pfred1> jdhNC http://www.youtube.com/watch?v=I5DCwN28y8o
[03:05:50] <pfred1> watch it to 1:01
[03:07:28] <pfred1> but if you watch the whole thing you find out how Juan really got screwed over

[13:21:16] <JT-Shop> I have to (want to) make 4 of these chin bolts and I'm looking for suggestions for the head part http://imagebin.org/197236
[13:21:46] <JT-Shop> basically a 3/8 rod threaded on one end with the funny head on the other end
[13:22:28] <pfred1> if you need Chins get a Chinese phone book
[13:24:51] <pfred1> when I got my mill it didn't come with a 7/16s x 14 drawbar so I cut the threads off one and welded it to a piece of rod, it has held up remarkably well over the past 20 or so years
[13:25:09] <pfred1> better than I thought it would when I made it
[13:25:48] <jthornton> that's kinda what I thought I would do weld the preformed head to the rod
[13:26:13] <jthornton> it has to hold up to cannon fire :)
[13:26:22] <pfred1> let me put it this way I don't even think about it much anymore it is as if it was tapped into a solid piece of steel
[13:27:01] <pfred1> at one time all refined metal was molten
[13:27:36] <pfred1> I'd take a picture of my welded drawbar but it is in my mill holding in a 2 inch shell cutter
[13:28:08] <jthornton> no need, I understand
[13:28:37] <pfred1> if a weld is done well it is remarkably strong
[13:28:54] <pfred1> know what blows my mind worse though? when I braze together bandsaw blades
[13:29:06] <pfred1> and they break somewhere other than where i brazed them
[13:29:43] <pfred1> I do a double scarf joint when i do that lots of surface area
[13:30:16] <pfred1> well double beveled
[13:31:28] <pfred1> today I try to stay away from superglue techniques but sometimes it is the most intelligent option

[17:26:39] <pcw_home> Jymmm must be a communist. how can you be against infinite growth?
[17:26:41] <pcw_home> the successful strategy of consumer societies and cancer tumors
[17:27:53] <Jymmm> pcw_home: But, financial growth != Infinite Growth =)
[17:29:36] <Jymmm> pcw_home: But you gotta admit, a nice 17x20 Glossy of a 16" caner tumor is pretty sexy
[17:29:54] <Tom_itx> in who's world?
[17:30:03] <Jymmm> Tom_itx: yours!
[17:30:11] <Tom_itx> nope not mine
[17:30:56] <Jymmm> Tom_itx: Didn't you read the disclaimer on those AVR's? "Will cause cancer"
[17:31:09] <Tom_itx> no
[17:31:12] <Tom_itx> didn't 'click'
[17:31:16] <pcw_home> That clip reminded me of the story of stuff (which is a lot more preachy)
[17:32:03] <Jymmm> Tom_itx: and you thought you were just getting a pot belly, better go get an xray RADIATION exposure done =)
[17:33:03] <Tom_itx> the xray is more likely to introduce cancer cells
[17:34:05] <Jymmm> pcw_home: Someone invented a 100,000 Mile tire. Goodyear bought and squashed the patent on it. Some college created a car (from various off-the-shelf parts) that does 109 MPG back in the 80's, Some oil company bought and squashed that too.
[17:35:24] <pcw_home> I didnt know about the inkjet printer thing (cartridges yes)
[17:35:43] <Jymmm> Now, we have laws banning incadesent light bulbs, yet are given CFL's that have mercury, do NOT last 10 years, and now will go into our landfills.
[17:37:54] <pcw_home> CFLs supposedly are still a win due to the amount of mercury released from coal burning plants but
[17:37:56] <pcw_home> you would think they they could come up with something better
[17:38:05] <Jymmm> Kill someone, get 3-5yrs. Steal $50K you get 10-15yrs. WTF is up with that?!
[17:38:37] <Jymmm> pcw_home: They have, LED. But just costly as PG&E and the like are not sponsoring them.
[17:39:45] <pcw_home> yeah not really cost effective yet (though we have some new LED streetlights around here)
[17:40:42] <Jymmm> pcw_home: The CFL might eb a win if that actually lasted 10 years. but they barely last 9months in a typical household usage. (on/off just kills the life of them)
[17:41:10] <pcw_home> I think the replacement/service cost of the streetlight makes them cost effective
[17:41:37] <Jymmm> We do keep one CFL on 24/7, it has lasted 18 months.

[17:42:15] <Jymmm> pcw_home: As in street lighting, or signal (red/yel/grn) ?
[17:42:19] <pcw_home> we have many CFLs that are 5 or more years old but some dont even last 6 months
[17:42:43] <pcw_home> No regular white streetlight
[17:43:15] <Jymmm> Haven't seen that yet. SJ just turns off half the lights due to budget cuts instead.
[17:44:07] <pcw_home> wonder if any cars have LED headlights yet?
[17:44:23] <Jymmm> I think BMW, might
[17:45:13] <Jymmm> 85 doens't have street lights in certain parts of it. Iwas able to drive by my hand held LED flashlight and see across all four lanes.

[17:48:51] <Tom_itx> is it right for a company i quit doing business with to buy the one i chose instead and take it over so i'm back to square one again?
[17:49:23] <Jymmm> Tom_itx: For buying or selling to?
[17:49:39] <Tom_itx> a service

[17:50:03] X704 is now known as WalterN
[17:50:12] <Tom_itx> in this case consumer
[17:50:55] <Jymmm> Tom_itx: It happens, and it sucks. Big Evil guy eats little Nice guy, you get screwed in the end.
[17:51:19] <Tom_itx> or move to the next one and wait to be eaten?
[17:51:57] <Jymmm> Or hope that Nice Guy gets to continue to play by their rules and not of Evil one.
[17:52:24] <Tom_itx> there was absolutely no notice given, just a local news announcement and it all happened within a week

[18:06:15] <pcw_home> " So did the eWaste dumping in Ghana. They could have shedded all that PVC and made into pellets for reuse"
[18:06:17] <pcw_home> without a requirement that things be built with recycling in mind is cheaper to just dump them and the environmental problems
[18:06:19] <pcw_home> on some poor country
[18:07:41] <Jymmm> I still think it be cheaper to shred it, than transport it around the world.
[18:08:18] <Jymmm> the thing that fubar's us is the EPA regulations.
[18:08:43] <Jymmm> Oh that has lead, OMG you have to this and this and this and this...
[18:09:07] <pcw_home> Look at how many working ewaste recyclers exist in country with any kind of environmental protection (0 maybe)
[18:10:37] <Jymmm> That's why a lot of mfg is done in China, no environmental regulations at all.
[18:10:51] <Jymmm> at least nothing like here.
[18:11:23] <pcw_home> if we didnt have the EPA every river would be toxic waste dump instead of only 1/2 or so :-)
[18:11:34] <Jymmm> lol
[18:12:32] <Jymmm> and thus why I carry a fire starter, can boil off all those 3 headed zombie viruses in the water!

[20:23:06] <elmo40> kernel 3.x, they have a low-latency version? i booted into DreamStudio 11.04 and when Grub loads it says 3.0.0-9-lowlatency
[20:23:19] <elmo40> not sure if it is realtime or not.
[20:23:31] <elmo40> how would i check for that?
[20:24:20] <pfred1> I've never seen the stuff EMC uses in a mainstream kernel yet. Namely the RTAI extensions
[20:29:25] <archivist> elmo40, http://wiki.linuxcnc.org/cgi-bin/wiki.pl?action=browse&id=Latency-Test&revision=84
[20:29:56] <pfred1> but I wonder if the newer kernels can net lower latency scores?
[20:30:14] <pfred1> can they be patched for RTAI?

[21:05:07] <elmo40> hrmm. so i cant even install emc2-sim on a newer OS (11.04) Depends on python < 2.7 but 2.7.1 will be installed
[21:05:25] <pfred1> change the kernel
[21:05:28] <elmo40> the .1 is that much different that emc2 cant use that version of py? i cant see that
[21:06:51] <pfred1> probably just need to create a link with a version number the script will recognize but if it isn't that easy yo ucan install another local copy and use it
[21:07:33] <elmo40> just wondering if i can just run the latency test, thats all
[21:07:33] <cradek> note that it says < 2.7, which is how you spell 2.6.x
[21:07:41] <cradek> so it's not a difference of 2.7 vs 2.7.1 at all
[21:07:42] <pfred1> I've had to do it with librarries multiple times
[21:07:44] <elmo40> ya, got that now ;) took too many seconds
[21:08:21] <pfred1> then you can still install a different local version
[21:09:09] <elmo40> is there an rt-tests in your repo?
[21:09:32] <elmo40> ...'tests and measures various real-time components...'
[21:10:01] <elmo40> ah, lol, when i apt-get it they want to install 2.6.38-13 :-P
[21:10:15] <elmo40> i dont think this kernel is real time, only low latency.

[22:11:48] <pfred1> but i made the original table and gave it to him
[22:13:24] * pfred1 thinks it is cool he hosts it but ther isn't a link to it from the rest of his website ...
[22:15:44] <pfred1> I copied it off a hand out chart we got off our steel supplier when I worked in a machine shop I wore out my original I still have it kicking around though
[22:16:24] <pfred1> is this neat plastic thing
[22:17:16] <pfred1> it was funny when my shop foreman gave it to me he said, I now present you with the magic key ...
[22:17:36] <pfred1> he was right it's awesome
[22:46:49] <skunkworks> pfred1: what do you mean?
[22:47:03] <pfred1> skunkworks about the magic key?
[22:47:18] <elmo40> there is no 0.010" drill?
[22:47:28] <skunkworks> oh - I see - he has other charts but not that one
[22:47:36] <elmo40> i guess 0.0098 is close enough ;)
[22:48:05] <pfred1> skunkworks oh about no link in his site yeah that was why I sent it to him I thought his other charts weren't all that comprehensive really
[22:48:42] <pfred1> elmo40 you can get any drill size custom made but there are only a fixed number of "standard" industrial sizes
[22:49:16] <pfred1> so called off the shelf tools
