#emc | Logs for 2008-06-30

[00:08:28] <skunkworks> he was at the fest?
[00:08:37] <skunkworks> damn. missed another one
[00:08:56] <skunkworks> or did I meet him?
[00:09:07] <SWPadnos> dunno. his name is Phil
[00:09:37] <SWPadnos> how close to Stevens Creek are you?
[00:10:56] <skunkworks> me?
[00:11:00] <SWPadnos> yes
[00:11:12] <skunkworks> never heard of it.. let me look
[00:11:55] <SWPadnos> heh
[00:12:59] <skunkworks> ummm - really... in WI?
[00:13:05] <SWPadnos> yep
[00:13:55] <SWPadnos> I think that's what it's called anyway
[00:14:21] <skunkworks> I can't find it.. yahoo is finding me stevens creek road in long lake wi
[00:14:24] <SWPadnos> oh - Stevens Point
[00:14:26] <SWPadnos> oops
[00:14:27] <skunkworks> oh
[00:14:31] <skunkworks> heh
[00:14:35] <skunkworks> that I have heard of
[00:15:39] <skunkworks> about 150 miles north east of here.
[00:15:49] <SWPadnos> ok, so a ways away
[00:15:56] <skunkworks> east north east..
[00:16:15] <SWPadnos> my wife will be there, and maybe me too, in early August
[00:16:25] <SWPadnos> there's a recumbent bike rally
[00:16:33] <skunkworks> ah - you sure come to wisconsin a lot.. ;)
[00:16:50] <SWPadnos> well, since her family is in Manitowoc and Ripon - yeah :)
[00:17:08] <SWPadnos> http://www.hostelshoppe.com/recumbent_rally.php
[00:17:26] <SkullWorks_PGAB> What is a "recumbent bike rally"
[00:17:37] <skunkworks> we just had s and s bike rally here their 50th. (in lacrosse)
[00:17:41] <SWPadnos> it's a gathering of people who have or are interested in recumbent bikes
[00:18:09] <skunkworks> bikes that you sit like your in a recliner.. (seriously)
[00:18:17] <SWPadnos> yep
[00:18:45] <SWPadnos> here's a cool one: http://www.flevobike.nl/content/view/16/79/lang,en/
[00:21:58] <SWPadnos> I think that's the only bike I've seen with the chain internal to the frame
[00:22:30] <SkullWorks_PGAB> Hmm - and I'd be a pariah if I had one cause I'd just HAVE to mount a little 2 cycle motor on one... Green power meets blue smoke... :)
[00:24:32] <SkullWorks_PGAB> But still @ nearly 180MPG I can claim less carbon stomping than driving my Mustang GT...
[00:25:16] <SWPadnos> at 22MPG (in my Jeep Grand Cherokee) I can probably claim less carbon footprint than your Mustang GT
[00:27:03] <SkullWorks_PGAB> I may have you beat - I get 19-23 city but hwy mileage is 27-29 @ 70mph
[00:27:23] <SkullWorks_PGAB> idling in Overdrive
[00:27:39] <SWPadnos> heh
[00:27:55] <SWPadnos> I'm sure it would help if I had a 4-speed transmission
[00:28:24] <SkullWorks_PGAB> ah yes mine has the 5spd manual
[00:29:20] <SkullWorks_PGAB> factory set shift points on the GT autos is weighted towards performance not economy
[00:30:58] <SkullWorks_PGAB> my 2.4Liter Nissan truck can't beat the GT's hwy mileage
[00:31:33] <SWPadnos> yeah, at highway speeds it's the shape that matters
[00:31:40] <SkullWorks_PGAB> it gets a flat 25mpg - city or hwy
[00:32:30] <SkullWorks_PGAB> unless I try to keep the crusie over 75mph then it drops to 20-21
[00:32:59] <SkullWorks_PGAB> made that mistake on the last cross country trip
[03:26:39] <cradek> yay, I got the holes tapped on jepler's mill's new table
[03:27:49] <cradek> jmkasunich: also I noticed my tapping head is JT6, the same as your QC30 find at HGR
[03:28:35] <cradek> if I had noticed that earlier I might have saved myself a few hours of work
[03:31:34] <cradek> (assuming I could get the existing one off...)
[03:36:03] <jmkasunich> what was the few hours of work? making an arbor?
[03:36:17] <cradek> tapping six thousand holes on the drill press
[03:36:27] <jmkasunich> oh
[03:36:44] <cradek> but with one tap, without breaking it!
[03:37:02] <jmkasunich> aluminum? 1/4-20?
[03:37:12] <cradek> yes aluminum, 10-32
[03:37:14] <jmkasunich> piece of cake with tapping head in drill press
[03:37:41] <cradek> I only had one tap, spiral flute - they seem pretty weak
[03:37:48] <jmkasunich> oh
[03:37:50] <jmkasunich> blind holes?
[03:38:15] <jmkasunich> (spiral flute taps do make me cringe a bit, I much prefer spiral point unless the hole is blind
[03:38:16] <cradek> nope, through, but I didn't have the spiral point tap that would have been much better
[03:38:27] <cradek> me too
[03:38:34] <cradek> I guess I need to get some
[03:38:47] <jmkasunich> that is the kind of job that I would defer until the tap arrived
[03:38:49] <cradek> I have a bunch of 1/4-20 - I try to use that whenever I can
[03:39:33] <cradek> I tried to talk him into it, but he wanted 10-32 so he can use sherline clamps and stuff
[03:39:43] <cradek> which I agree is a very nice feature
[03:40:00] <jmkasunich> "sure jeff, order the tap from McMaster"
[03:40:08] <cradek> heh
[03:41:42] <cradek> btw, I also discovered that unlike the HF drills, USA-made 135 degree split point screw machine drills drill the right size hole in the right place
[03:41:59] <cradek> it's a nice couple of features for a drill to have
[03:49:25] <chr0n1c> lol, i can sharpen a drill to cut dead nuts hole sizes for you by hand on a grinder or belt sander ;)
[03:50:06] <cradek> that I'd love to see.
[03:50:53] <chr0n1c> i'll show ya someday ;)
[03:51:41] <chr0n1c> the machinist handbook has an awesome section on drill bit points and sharpening
[03:52:10] <chr0n1c> i combined a few of the techniques to come up with my own sorta split point thing
[03:56:36] <chr0n1c> i could take a few pics of the drills i have at work, i haven't had to resharpen any of the set i have here because i am the only one who uses them ;)
[03:57:01] <chr0n1c> drill bits*
[04:47:37] <chr0n1c> ehh, cya!
[06:18:48] <alex_jon1> alex_jon1 is now known as alex_joni
[11:51:27] <_epineh> Hey all
[11:52:34] <micge1> hello
[11:52:53] <_epineh> 'nother stupid question for the night, is there a terminal program that installs with 6.06 BDI ?
[11:53:09] <_epineh> got emc up and running just need to program my servo drives now...
[11:53:41] <_epineh> router PC is miles away from internet
[11:53:41] <BigJohnT> do you mean EMC in a terminal
[11:54:00] <_epineh> just like hyperterminal for windows
[11:54:03] <_epineh> in ubuntu
[11:54:38] <BigJohnT> I don't know
[11:54:41] <_epineh> k
[11:54:50] <BigJohnT> what do you want to do?
[11:55:07] <_epineh> just program my PID settings via serial link
[11:56:14] <archivist> serial is basicly in by default on linux (or was) connect to /dev/tty
[11:56:18] <_epineh> I can d/l a prog if needed just easier if there is one loaded by default
[11:56:35] <_epineh> k
[11:56:39] <_epineh> I will give it a go
[11:56:42] <_epineh> thnx
[11:56:44] <BigJohnT> good luck
[11:56:50] <archivist> so many years since I did it
[11:57:03] <BigJohnT> afternoon archivist
[11:57:16] <archivist> morning
[11:57:23] <BigJohnT> * BigJohnT is still rubbing eyes and on first cup of joe
[11:58:04] <BigJohnT> _epineh: I'm just wondering why you don't set the PID settings on the computer with EMC?
[12:02:58] <archivist> _epineh, man getty and also lookup minicom
[12:04:33] <_epineh> BigJohnT, my drives are Elm Chan based, step/dir input they have PID settings onboard
[12:04:49] <_epineh> archivist, cheers, will have a look
[12:05:15] <_epineh> I couldn't get /dev/tty to work, I must point out I am a linux noob :-)
[12:05:50] <archivist> /dev/tty0 or 1 and see gety man
[12:06:15] <_epineh> k, I will try again...
[12:06:17] <_epineh> brb
[12:07:11] <archivist> /dev/ttty0 is the device you connect too
[12:07:22] <archivist> or 1 or.....
[12:19:52] <alex_joni> _epineh: /dev/ttyS0 probably for COM1 (in dos)
[12:20:04] <_epineh> didn't work,
[12:20:24] <_epineh> hi alex
[12:20:26] <alex_joni> _epineh: check that /dev/ttyS0 is there
[12:20:29] <alex_joni> hi _epineh
[12:20:30] <_epineh> k
[12:20:40] <alex_joni> ls -al /dev/ttyS*
[12:21:03] <_epineh> k
[12:21:29] <_epineh> I was trying the other ones by typing sudo screen /dev/tty0 - is that right ?
[12:26:29] <archivist> screen??
[12:27:07] <alex_joni> not right
[12:27:29] <alex_joni> try ls -al /dev/ttyS* first
[12:27:39] <alex_joni> then if ttyS0 is there, just run "minicom"
[12:27:59] <alex_joni> and it's got some text/graphical interface where you can set port & params
[12:30:36] <_epineh> k back
[12:30:45] <_epineh> yeah ttys0 is there
[12:31:01] <_epineh> I don't think I have minicom, tried that earlier
[12:31:09] <_epineh> gotta get it
[12:31:33] <alex_joni> sudo apt-get install minicom
[12:31:50] <_epineh> I had a little problem accidentally unplugged the keyboard lead a little, got a little radical for a while, so many terminal windows opening automatisally
[12:32:06] <_epineh> *automatically
[12:32:40] <_epineh> won't I need internet to do that ?
[12:34:47] <alex_joni> _epineh: sure you do
[12:34:56] <alex_joni> but you need internet for most anything these days
[12:36:05] <archivist> hence getty (bit harder to drive though)
[12:36:09] <_epineh> lol ya, router is in shed, with no internet...bummer, ah well I will d/l it an install tomorrow
[12:37:14] <archivist> try getty /dev/ttys0 9600,np,1 or whatever your setting/port are
[12:38:59] <_epineh> k
[12:44:29] <_epineh> no luck, thnx any way, I will get minicom happening tomorrow, been a long day
[12:44:51] <_epineh> gotta go to work in about 6 hrs, should probably get some sleep :)
[12:45:01] <_epineh> thanks all !
[12:45:41] <_epineh> bye
[12:46:08] <anonimasu> hello
[12:49:24] <alex_joni> anonimasu: capital S
[12:50:30] <anonimasu> ?
[12:51:03] <anonimasu> stockholm?
[12:51:39] <alex_joni> I meant archivist: capital S
[12:51:46] <alex_joni> in /dev/ttyS0 (not /dev/ttys0)
[12:52:58] <archivist> alex_joni, I have lc and UC on this box
[12:53:11] <alex_joni> lc and UC?
[12:53:27] <archivist> lower case upp case
[12:53:27] <alex_joni> 15:25 < archivist> try getty /dev/ttys0 9600,np,1 or whatever your
[12:54:08] <SWPadnos> ls /dev/tty[sS].[0-9]
[12:54:36] <archivist> and alex note caveate "or whatever your setting/port are"
[12:55:10] <alex_joni> yeah, well.. newbies don't know how to go from ttys0 to something else (based on whatever your port is :)
[12:55:34] <archivist> I cant know whats on his box :)
[12:56:11] <archivist> serial was allways a b***d
[12:56:24] <SWPadnos> beard?
[12:56:28] <alex_joni> b(tty)d ?
[12:56:30] <SWPadnos> bread?
[12:56:41] <SWPadnos> board?
[12:56:42] <archivist> bastard
[12:56:51] <SWPadnos> oooooohhhhhh
[12:56:53] <alex_joni> ahh.. I get it
[12:56:53] <SWPadnos> :)
[12:56:55] <alex_joni> a *
[12:57:03] <alex_joni> b(a *)d
[13:01:05] <archivist> I date from those days with serial terminals and all the fun RTS DTS CTS DTR.......bit and bauds, wrote a seral terminal in assembler for dos
[13:01:35] <archivist> I was trying to forget it all!
[13:04:26] <alex_joni> archivist: I bet you do ;)
[13:04:38] <alex_joni> I remember doign bit-banging serial on stupid pics in assy
[13:04:43] <alex_joni> that's a nightmare :D
[13:04:50] <archivist> yes!
[13:05:16] <archivist> my last serial pic was a remote control
[13:05:22] <alex_joni> * alex_joni hates pics
[13:05:29] <alex_joni> PICs that is..
[13:05:46] <archivist> horrible but cheap
[13:05:53] <alex_joni> the last one I had, went through some serious underclockign
[13:06:08] <alex_joni> it worked on 50Hz for a couple of cycles :D
[13:06:40] <archivist> you certainly need a logic analyser developing PIC software
[13:07:02] <alex_joni> 50Hz and 230V directly on the PIC was fun to watch :D
[13:07:18] <archivist> hmm nice
[13:07:41] <alex_joni> the compiler is also utter crap
[13:07:48] <alex_joni> I had a big lookup table for some conversions
[13:07:55] <alex_joni> and it never complained the lines are too long
[13:08:14] <alex_joni> instead it just took a couple of the subsequent lines of code as part of the table..
[13:09:02] <archivist> hehe, sounds like the Acorn C compiler I did a printer driver with for Riscos
[13:10:01] <archivist> serious bug in the switch case construct, it only used short branches, add line, crash!!!
[13:11:38] <archivist> PIC has issues with carries(it doesnt) on the program counter, hence tables dont work over page boundaries
[13:12:22] <alex_joni> yeah, I think I hit that one too
[13:17:02] <lerman__> lerman__ is now known as lerman
[13:18:12] <anonimasu> :)
[13:46:51] <Guest313> Guest313 is now known as skunkworks_
[19:32:51] <dave_1> does the dropbox still exist and if so where?
[19:34:01] <gefink> dave_1: http://pastebin.com/pastebin.php ?
[19:34:52] <BigJohnT> dave_1: I was told no a while back
[19:34:57] <BigJohnT> what's up
[19:35:20] <dave_1> oh darned I committed something a long time ago and wanted to take a look at it.
[19:36:14] <dave_1> it streamed gcode and kept track of modals.
[19:36:25] <dave_1> was used for restarting a program.
[19:36:32] <dave_1> in the middle
[19:36:58] <BigJohnT> darn
[19:37:37] <dave_1> I was thinking about combining using it in a script that did a cat with the output of that and the rest of the program.
[19:38:14] <dave_1> don't think I still have the source
[19:38:51] <dave_1> that was a couple of machines back
[19:38:54] <skunkworks_> you should ask Sweeper
[19:38:55] <skunkworks_> oops
[19:39:06] <skunkworks_> try that again. you should ask SWPadnos
[19:39:36] <dave_1> good idea
[19:40:29] <dave_1> off to look on another machine bbl
[19:43:26] <rayh> http://www.linuxcnc.org/dropbox/ will get you there dave_1
[19:44:08] <dave_1> thanks ray
[19:44:23] <dave_1> gonna run
[19:44:46] <Hugomatic> Hi guys... I'm playing around with my rotary table in Axis and I find it difficult to use: whenever I need to rotate a turn, my program needs to remember the current A axis position. Is there an easy way to home the A axis from the gcode? thanks
[19:46:59] <cradek> Hugomatic: I'm not sure what you mean by 'remember'
[19:47:46] <SWPadnos> the dropbox (or at least most of it) is at http://www.linuxcnc.org/dropbox/
[19:47:47] <Hugomatic> Hi cradek. Well, I mean if I want to make a second turn, I need to program "g1 a 720"...
[19:48:08] <SWPadnos> oh - I guess I could have read a little more :)
[19:48:13] <skunkworks_> heh
[19:48:17] <Hugomatic> But I'd like to say "g1 a+360"
[19:48:44] <cradek> g91 g0 a+360 will go one full turn positive, no matter what the current position
[19:48:59] <skunkworks_> sounds like a job for either incremental - or o-words..
[19:49:06] <Hugomatic> cradek: exactly what I'm looking for, thanks
[19:49:11] <SWPadnos> so would g92 a0 / g1a360
[19:49:21] <cradek> be sure to switch back to g90 when you want absolute mode again
[19:49:32] <SWPadnos> but that might blow up after a long time
[19:50:09] <skunkworks_> * skunkworks_ waits for cradek to yell at SWPadnos
[19:50:11] <Hugomatic> ´╗┐SWPadnos: what do you mean? a "joint following error"?
[19:50:43] <cradek> * cradek doesn't have any problem with using g92 within a program
[19:50:49] <SWPadnos> no, eventually (after some days/weeks/months), you might start losing precision when the joint offset gets too big
[19:50:54] <skunkworks_> :)
[19:51:16] <SWPadnos> then again, it's a double in the interp, so maybe that would never happen (for small values of never)
[19:51:28] <Hugomatic> I'm always turning in the same direction for an hour... is it going to be a problem?
[19:51:39] <SWPadnos> not for an hour
[19:52:02] <SWPadnos> but remember to use G92.3 or whatever it is you need to clear those G92 offsets every once in a while
[19:52:29] <cradek> after the program run you'll see A: 360000, and then you can just poke 'home' to zero it
[19:52:36] <Hugomatic> Well, in that case, if I can reset it from the code, it won't be a problem
[19:52:51] <jepler> going to +10000 revolutions during one emc session might be enough to see problems
[19:52:59] <Hugomatic> cradek: how do I poke home?
[19:53:14] <jepler> cradek means you press the "home" button on the GUI
[19:53:23] <jepler> you can't execute the homing procedure from gcode
[19:53:28] <Hugomatic> OK... I know how to do that
[19:53:28] <cradek> sorry, I wasn't being obscure on purpose
[19:54:21] <Hugomatic> jepler: that's unfortunate... I'd like to be able to question the interpreter from the code (getting axis positions, modes, tool number and stuff)
[19:55:38] <cradek> what kind of work are you doing Hugomatic?
[19:56:13] <Hugomatic> I'd like to build electronic kits and robots
[19:57:32] <Hugomatic> something like open source projects for milling machines
[19:57:37] <chr0n1c> anyone in germany? i jsut talke dto my little bro (who is stationed in germany) who happens to be home on leave.. he was telling me about crazy stuff over there
[19:58:10] <gefink> chr0n1c: what stuff?
[19:58:49] <chr0n1c> gefink, like the police and how all german chicks would do anything for an american soldier ;)
[19:59:02] <cradek> sounds interesting, but actually I meant to ask what kind of job involves using the rotary table this way
[19:59:11] <chr0n1c> and he was telling me about some amazing churches with huge pipe organs...
[19:59:42] <Hugomatic> cradek: I don't have a lathe, so I'm using the rotary table instead
[19:59:56] <gefink> yes, we have muchof this
[19:59:57] <chr0n1c> he said his crazy squad buddies go out and get plastered and start fights all the time so he hangs out by himself a lot...
[20:01:02] <chr0n1c> i meant to ask about the music scene over there, but didn't have time.. we're going to lunch tomorrow.. i'll ask then
[20:01:48] <gefink> chr0n1c: http://de.wikipedia.org/wiki/Orgel
[20:02:28] <Sweeper> I'd go to germany for CCC \o
[20:02:29] <chr0n1c> gefink, thank you for the link, amazing!
[20:02:50] <gefink> chr0n1c: i think you can stream german Radio
[20:04:16] <chr0n1c> my little bro was infatuated with rammstein (the music group) when he was younger i think that's part of the reason he ended up in germany...
[20:05:21] <SWPadnos> here's a cool one: http://en.wikipedia.org/wiki/Cologne_Cathedral
[20:09:33] <chr0n1c> * chr0n1c is about to start milling the midibox_core circuit board!
[20:11:03] <kirk_wallace> Hello, I just noticed some strange behavior on my lathe. I ran about twenty parts, and then started checking my g-code file to edit it for the next parts. I noticed that the mouse was jumping around as if the system was under a load.
[20:11:47] <cradek> I bet your backplot has built up a bit. if you clear it (eraser brush icon) does it go back to normal?
[20:12:32] <cradek> I see this a lot. the backplot throws out "very old" moves but maybe it needs to do it a little sooner.
[20:12:36] <kirk_wallace> I toggled the AXIS machine power button and the load went down.
[20:12:59] <cradek> hm, next time you get this, run top and see what it's doing
[20:14:06] <kirk_wallace> In the system monitor / processes it indicated two process as active, EMC ~ 10% and Monitor ~6%.
[20:15:48] <kirk_wallace> That confussed me a little because the CPU load was 90% and no real load from processes.
[20:16:39] <kirk_wallace> I wonder if confussed is a word. confused
[20:16:48] <chr0n1c> top uses less resources on it's own when run from a terminal, the system resources adds 30% load to my CPU when i use it
[20:18:55] <kirk_wallace> I'll clear backplot and/or use top next time. It's cleared up now though.
[20:19:07] <kirk_wallace> Thanks.
[20:23:45] <fenn> kernel processes don't show up in top
[20:27:01] <chr0n1c> is there ztop or something though for the kernel?

[22:32:24] <davidf> hi
[22:34:57] <davidf> my cnc machine hd crashed. I want to download a 6.06 or 8.04 image but can't get my cr rw/ drive installed. Help?
[22:35:15] <davidf> cd not cr
[22:40:26] <chr0n1c> davidf, what's the install hiccup?
[22:41:13] <chr0n1c> doh!
[22:41:20] <davidf> chr0n1c, Hi.
[22:41:44] <davidf> Well, I had a cdrom installed, and replaced it with a cr rw.
[22:42:00] <davidf> But the computer doesn't see it.
[22:42:04] <chr0n1c> are the jumpers for master slave set right?I
[22:42:36] <chr0n1c> is the power plug in (seriously, i have left the power plug out before and been like WTF!)
[22:43:26] <davidf> hm, there was a problem with that. I installed ubuntu with the hd set as slave I think, and have had difficulties with that since.
[22:44:13] <davidf> I had a cdrom that was fine on this box, but I replaced it withthe cd r/w and it doesn't work.
[22:44:14] <chr0n1c> if the hd and cdr are on the same ide cable, one needs to be slave and one needs to be master, usually the hd is master
[22:44:33] <davidf> lol. yeah it's in. :)
[22:45:09] <davidf> separate cables.
[22:45:38] <chr0n1c> -- is the second ide channel turned on in bios?
[22:45:56] <davidf> I tried sudo mount /media/hdb1
[22:46:27] <davidf> and got can't find hdb1 in /etc/fstab or /etc/mtab
[22:46:41] <chr0n1c> does your bios detect the drive?
[22:47:10] <davidf> hmm... I'll need to look and that means I'll have to disconnect for awhile.
[22:47:46] <chr0n1c> m'kay
[22:48:21] <chr0n1c> davidf, http://books.huihoo.org/debian-gnu-linux-guide-to-installation-and-usage/node79.html
[22:48:35] <davidf> I have to run out for a bit. I need to get to a store to pick up a cd.
[22:48:44] <davidf> Thanks, I'll be back soon!
[22:48:47] <davidf> Bye
