#emc | Logs for 2008-07-14

[00:37:14] <dmess> make it work...HaRD.. and convince them they NEED 3 0or 4 more machines
[00:38:22] <mdynac> np they are an edmnetwork customer for life....
[00:39:31] <dmess> understand the turbine industry is going BALISTIC..... 787 superjet...eclipse... ALL some crzy wings that need attatchement
[00:40:12] <mdynac> yep
[00:40:46] <dmess> can i sighn on....
[00:42:49] <dmess> we ahve 2 of the LARGEST landing gear mfg's within' 100 miles( 160 KM) ALL using the same supplier base.... this is gonna get ugly SOON
[00:43:27] <dmess> OR Expensive....
[02:11:38] <tomp2> mdynac: just read back the logs, watcha thinking to do after wire break stops it? emc's not at the beginning of any gcode line.
[02:12:52] <tomp2> i dont even know if you can find out the line that was being executed.
[02:13:43] <mdynac> why not the pause function in axis?
[02:14:10] <tomp2> yeh, that pauses, but are you just going to thread and start again?
[02:14:27] <tomp2> maybe a few steps further than the break point? dunno
[02:14:56] <tomp2> when you thread you can tell ( shorted or not :)
[02:15:26] <mdynac> ell i still gotta test it out, just doing the figuring right now
[02:15:40] <tomp2> yeh, the pause is a good start
[02:15:51] <mdynac> i assumed the pause function stopped immedeatly
[02:16:05] <mdynac> it sure is the easiest...
[02:16:23] <mdynac> why reinvent the heel if i dont have to...
[02:16:36] <mdynac> damn w key on my laptop....
[02:18:35] <tomp2> heh, i got dueling keyboards here cuz the laptop kbd is crap. hurray for usb kbds.
[02:24:18] <tomp2> mdynac: dimas: you guys would be interested inthis ( if the guy would ever supply the code he 'open-sourced') http://code.google.com/p/edmcontrol/source/checkout
[02:37:10] <pminmo> Can annybody point me to where the emc config files are in the unpacked iso directory tree?
[02:38:05] <jmkasunich2_> I think it is /etc/emc2/sample-configs
[02:39:11] <pminmo> not the installed directory, the .iso file unpacked
[02:40:47] <pminmo> i.e. casper-dists-install-isolinux-pics-pool-preseed
[02:40:49] <jmkasunich> I don't know what you mean
[02:41:22] <jmkasunich> oh
[02:41:40] <jmkasunich> no idea - I've never had occaision to look (and don't have an unpacked iso handy here)
[02:42:01] <jmkasunich> can't you use find?
[02:42:04] <pminmo> i suspect it's my linux ignorance
[02:42:05] <cradek> they're in the squashfs along with the rest of /
[02:42:17] <cradek> but editing them this way is surely not what you want
[02:42:40] <pminmo> yes maybe I'm going doen the wrong path
[02:42:47] <pminmo> I want to give a friend
[02:43:11] <pminmo> a cd with my .ini and hal files in the proper place when installed
[02:44:18] <cradek> you might want them to appear in the installing user's home directory, but that's not easy since that gets generated programmatically
[02:44:57] <jmkasunich> you are probably going to have to do a lot of work, in order to save your friend a tiny bit of work
[02:45:23] <jmkasunich> it might be simpler to say "install this CD, then copy these ini and hal files"
[02:45:34] <jmkasunich> (from a usb stick, or a website, or an email, or whatever)
[02:45:57] <pminmo> ok is there a way I can build the equivalent of a batch file to do the trick?
[02:46:53] <jmkasunich> "the equivalent of a batch file" = a script (linux speak)
[02:47:05] <pminmo> ok :-)
[02:47:16] <jmkasunich> anything you can do at the command line you can do in a script - its just a file with the commands in it
[02:47:43] <cradek> you could just tar up the config and then let him untar [like unzip] it.
[02:47:55] <cradek> that's the customary way to send a directory with some files in it.
[02:48:13] <pminmo> makes sense
[02:49:07] <pminmo> so probably the thing to do would be to take the existing configs dir copy it and add the extra files and let the install configs be overwritten
[02:49:23] <pminmo> so he would have all of them
[02:49:52] <cradek> no, you should not overwrite anything in /etc. a custom config goes in the user's home directory.
[02:50:10] <cradek> ~/emc2/configs/pminmos_config
[02:50:21] <pminmo> thanks
[02:51:47] <pminmo> create archive .tar ?
[02:51:58] <pminmo> via file browser
[02:54:30] <tomp2> man tar to see how to use it
[02:54:58] <pminmo> I feel like I'm in 1st grade again...:-(
[02:55:22] <jmkasunich> tar has about 47 thousand options ;-(
[02:55:22] <tomp2> tar -cvvf foo.tar foo/
[02:55:23] <tomp2> tar contents of folder foo in foo.tar ( test it, untar it, see if its what you want :)
[02:56:14] <pminmo> I 'm seeing them now
[02:56:34] <jmkasunich> tomp2's example sounds reasonable
[02:57:00] <jmkasunich> tar -cvf (name-of-new-tarfile) (name-of-directory-to-tar)
[02:57:05] <jmkasunich> to unpack it:
[02:57:18] <jmkasunich> tar -xvf (name-of-tar-file)
[02:57:54] <pminmo> Ok, thanks I think I have enought to go off and read for a while...
[02:58:13] <pminmo> thanks guys
[02:58:17] <pminmo> later
[03:10:28] <dmess> balls to the wall BOYS
[03:26:48] <mdynac> well it looks like the pause function of axis stops the machine right on the spot, according to my thou indicator......so it should be a good wire break detection input, halui.program.pause
[03:29:14] <jtr> tomp2: did you find contact info for the edm project? I'm wondering if the "name" of the project owner might be a gmail address.
[03:32:50] <tomp2> jtr: i have had no luck finding the author or even a general contact to googlecode, if you have any luck, please post it for the group
[03:33:38] <tomp2> mdynac: cool, can you thread & resume?
[03:35:32] <mdynac> well i do not have my edm up here in cheeseland, going back to ill tomorrow....
[03:35:39] <tomp2> jtr: i didnt uss that right away, how might i format the project name into a gmail address?
[03:36:29] <tomp2> wisconsin!?, then back to flatland ;)
[03:36:36] <mdynac> yep
[03:37:43] <tomp2> wisconsin advertises their instant lotto on billboards reading "faster than a car with Illinois plates"
[03:38:01] <mdynac> ha
[03:38:30] <tomp2> uss/suss
[03:39:41] <mdynac> i have my tiny 1.5" travel soon to be mini-edm up here with me
[03:40:06] <tomp2> jtr: centurion111@code.google.com??
[03:40:13] <mdynac> the u/v axis off an old japax......
[03:40:21] <tomp2> mdynac: nice orbiter :0
[03:41:01] <tomp2> ditto, got one in basement, nice schneeberger crossed roller ways, tho i dont think i got 1.5" travel
[03:41:02] <mdynac> gonna be a .004 wire machine
[03:42:31] <mdynac> this one goes way farther than the limits, so i increased it from 1" to 1.5" with about .5 left not used...
[03:42:47] <jtr> tomp2: on the Project Home tab, it shows the project owner as centurion111. I'm just making a wild guess that tacking on @gmail.com might actually be a/the contact method.
[03:43:02] <tomp2> mdynac: i read you got one of those reciprocating wedm's! they're great fun when the wire breaks, cuz it's going like 1km/minute. the room is suddenly filled with coily wire.
[03:43:12] <tomp2> jtr: now i got it, will try thx!
[03:43:32] <mdynac> yes we do, the chinese thingy......
[03:43:39] <jtr> hope it works!
[03:45:43] <mdynac> it slings oil everywhere, the guards don't help much, you have to add more to keep up with it, but the machine tool itself really gets messy.....
[03:52:04] <tomp2> with oily coolant everywhere, not much need for anti-electrolysis circuits ;) ( its a 'feature')
[03:53:37] <mdynac> its a slow machine, but it costs pennies an hour to run....the big selling point.
[03:56:04] <mdynac> no feedback, runs at a set feedrate
[03:56:26] <mdynac> no scales
[03:57:20] <jtr> tomp2: awallin owns a project there - maybe he can help: http://code.google.com/p/monocam/
[04:02:17] <tomp2> jtr: thats right , i stumbled into his project there, thx again
[04:03:28] <jtr> hope it helps. good night.
[04:03:35] <tomp2> mdynac: old (very old ) wedms had no dro and were open loop. a very good machine tool and electronics doesnt loose steps.
[04:03:42] <tomp2> jtr: gnite
[04:04:10] <mdynac> that is true
[04:05:46] <mdynac> i meant no gap feedback, sorry
[04:06:14] <mdynac> it runs open looped steppers
[04:07:18] <mdynac> the spark gap voltage does affect the feedrate....
[04:07:57] <mdynac> if you run any cnc slow enough it can edm
[04:09:56] <tomp2> servo edm vs running slower than optimum or even near it
[04:11:59] <mdynac> well gotta go, later all
[04:13:59] <tomp2> gnite
[04:14:39] <tomp2> awallin's site list planet-emc, good find
[06:16:25] <Killua> Bonjour
[06:16:40] <Killua> est-ce que quelqu'un pourrais m'aider s'il vous plait ?
[06:18:03] <Killua> Can someone help me ?
[06:27:06] <toastydeath> with emc or machining in general
[06:29:55] <alex_joni> Killua: it's best to just ask your question.. someone might answer
[06:31:14] <Killua> emc
[06:32:06] <Killua> I get a error when I run EMC2
[06:32:28] <Killua> I tried SIM
[06:33:23] <alex_joni> what's the error?
[06:34:02] <Killua> it's like this
[06:34:04] <Killua> http://www.cnczone.com/forums/showthread.php?t=56881
[06:47:32] <Killua> can you help me ?
[06:49:35] <alex_joni> looking now
[06:49:42] <alex_joni> are you sure it's the same error?
[06:50:28] <alex_joni> the error on cnczone is this:
[06:50:43] <alex_joni> "Can't write to /dev/rtai_shm - aborting"
[06:51:09] <Killua> ok wait
[06:51:14] <Killua> please
[07:07:19] <Killua> my error is "Can't read '/usr/realtime-2.6.24-19-generic/modules/rtai_tal.ko : No such file or directory
[07:09:21] <Killua> ERROR : Module rtai_hal does not exist in /proc/modules
[07:22:14] <alex_joni> Killua: wrong kernel
[07:22:28] <alex_joni> it needs to be -rtai
[07:22:50] <alex_joni> you probably selected the wrong kernel on boot
[07:28:48] <Killua> ???
[07:29:09] <Killua> ok
[07:31:52] <chr0n1c> hit esc to get into the grub boot menu when restarting the box
[07:32:04] <chr0n1c> select the - versionrtai
[07:32:17] <chr0n1c> select the -rtai version *
[07:32:34] <Killua> ok
[07:35:59] <Killua> esc does nothing
[07:36:25] <chr0n1c> it says "hit esc to enter the boot menu"
[07:36:34] <Killua> I must reboot ?
[07:36:45] <chr0n1c> when the comuputer boots
[07:36:48] <Killua> ah ok
[07:36:48] <chr0n1c> yes
[07:39:08] <alex_joni> Killua: you can also edit /boot/grub/menu.lst to change the default kernel
[07:39:33] <alex_joni> but you need careful when you do that.. or it won't start at all :)
[07:39:42] <Killua> ok
[07:39:49] <alex_joni> need to be..
[07:40:13] <Killua> I did it
[07:40:20] <Killua> now my computer
[07:40:27] <archivist> keep a copy so its easy to revert
[07:40:54] <Killua> I have a white screen
[07:42:07] <Killua> I don't see anything on screen
[07:42:11] <Killua> on my screen
[07:50:09] <Killua> why my screen is white when I select the -rtai version ?
[07:50:37] <chr0n1c> * chr0n1c doesn't know why
[07:50:43] <archivist> nor me
[08:38:37] <scutsxg> it is so quiet
[10:18:32] <Killua> Why my screen is all white when I am on the RTAI kernel please ?
[10:52:15] <alex_joni> Killua: during boot?
[10:52:19] <alex_joni> or afterwards?
[10:58:06] <alex_joni> ctrl-alr f1 brings you a console?
[14:13:19] <jepler> oooh http://www.sump.org/projects/analyzer/
[14:13:41] <jepler> unfortunately the exact board he used isn't available anymore; the newer boards from the same folks now have SDRAM instead of SRAM
[14:14:16] <jepler> fortunately the FPGAs are bigger now so you still can get a fair number of captured samples in the internal block SRAM
[14:30:44] <jepler> oh wait, I think it's the "S3BOARD" from digilent
[15:37:25] <[1]a-l-p-h-a> [1]a-l-p-h-a is now known as a-l-p-h-a
[16:07:19] <Vq^> is it possible to scale only rapid traverse?
[16:08:43] <cradek> no, feed override affects all moves
[16:13:06] <DaViruz> why would you use feed override to change rapid traverse when rapid traverse has it's own setting?
[16:14:58] <cradek> in emc2, there is one feed override that affects all moves
[16:16:40] <DaViruz> hmm, ok, i really don't see why you would want to make the rapid feed the same as normal feed
[16:20:05] <rayh> DaViruz, Rapid is not a feed. It's a get someplace as quickly as possible.
[16:20:49] <rayh> During testing or first run of a program you will probably want to reduce rapid but during running you will not.
[16:20:50] <DaViruz> well yes, bad choice of words on my part, but you just proved my pooint
[16:21:18] <Vq^> mr OoBIGeye asked me and i think he was concerned about using feed override when tapping
[16:24:29] <DaViruz> hmm, ok, i've never felt the need to reduce rapid during dry runs but i guess it might be useful in some cases
[16:27:11] <rayh> I've seen a couple of controls that had separate feedrate override and rapid reduce.
[16:37:22] <[1]a-l-p-h-a> [1]a-l-p-h-a is now known as a-l-p-h-a
[17:37:32] <[1]a-l-p-h-a> [1]a-l-p-h-a is now known as a-l-p-h-a
[18:26:40] <anonimasu> hm.. the way emc works with the feed override is the same as heidenhain machines do
[18:37:31] <[1]a-l-p-h-a> [1]a-l-p-h-a is now known as a-l-p-h-a
[20:35:37] <chr0n1c> would anyone be interested in 5 N.O.S. "microswitch" aKA: Honeywell industrial roller/plunger limit switches? i came across them today and thought i'd ask before they hit eb*y
[20:35:59] <chr0n1c> ... only thing is i don't have any boxes for them, but they are un-used
[20:36:15] <chr0n1c> $40 bucks a pop from mcmaster...
[20:46:25] <chr0n1c> oh, i'd like to throw in the fact that they ARE NOT "hot"
[20:46:31] <chr0n1c> :D
[21:25:27] <chr0n1c> *sold, thank you!
[21:26:11] <jymm> SWPadnos: ping
[21:35:11] <chr0n1c> someone needs to ping my webhost, can't get to my email *&%$!
[21:35:32] <jymm> chr0n1c: it's been hacked, you lose!
[21:35:45] <chr0n1c> DOH!

[21:38:35] <alex_joni> good night all
[21:38:42] <jymm> alex_joni: thanks
[21:38:46] <chr0n1c> cya alex
[21:39:25] <alex_joni> jymm: I think europe for 2 weeks
[21:39:53] <jymm> alex_joni: that's what I needed to know.... didn't want to ship a pkg to him while away
[21:40:15] <chr0n1c> so like, maybe they have been hacked? both websites of mine are down and the email servers AND their website is down.
[21:40:25] <alex_joni> jymm: right..
[21:40:37] <alex_joni> unless you want to ship to europe
[21:40:46] <jymm> nope =)
[21:41:09] <alex_joni> ok.. see ya..
[21:41:14] <jymm> hasta
[21:41:15] <alex_joni> hope all is well with you
[21:41:40] <chr0n1c> they should train dolphins to swim wearing a backpack for shipping across the pond
