[02:16:11] <jepler> can someone tell me what the third row of the "intermittent lube" chain (the one that uses %I4 AKA lube-up) is for?
[02:18:59] <cradek> hmm, I can't run that without realtime can I
[02:19:32] <jepler> you can rip out the parport stuff
[02:19:38] <jepler> actually I'm about to check in a simulator version of that
[02:22:24] <skunkworks> took the tach of the back of the GE servo - it has a 3/8 shaft out the back ;). That is the size of the encoder hub.
[02:22:29] <cradek> did you have to monkey with the limit switches?
[02:22:43] <jepler> I took the limits out
[02:24:01] <CIA-5> 03jepler 07HEAD * 10emc2/configs/demo_sim_cl/ (8 files): simulated system with classicladder
[02:26:48] <skunkworks> I hooked it up to the h-bridge - wow. with how low inertia is - I can switch from 2500rpm to -2500 rpm without even a hickup.
[02:27:41] <cradek> with pid, or just on/off?
[02:27:54] <skunkworks> just on and off. I need to mount the encoder yet.
[02:28:05] <skunkworks> that is next ;)
[02:28:31] <skunkworks> or on -on :)
[02:28:51] <CIA-5> 03jepler 07HEAD * 10emc2/src/Makefile: copy common files into demo_sim_cl
[02:30:41] <skunkworks> (still hooked up as a spindle)
[02:31:10] <cradek> still cool
[02:31:23] <skunkworks> very
[02:31:49] <cradek> jepler: I think iocontrol.lube_level is supposed to be an alarm input of some kind, and this is supposed to simulate 20 minutes worth of lube
[02:32:09] <jmkasunich> ?
[02:32:21] <jmkasunich> I thought it was an intermittent lube thing
[02:32:36] <jmkasunich> run the lube pump one minute every 20, or something like that
[02:32:36] <cradek> the bottom rung
[02:32:44] <jmkasunich> says /me without looking at it
[02:32:51] <jepler> there's a part that is 10 seconds on 20 seconds off
[02:33:02] <cradek> it runs lube 10 out of every 30 seconds, plus it does something else too
[02:33:08] <jepler> but the bottom part does something after 20 minutes
[02:34:08] <cradek> I wonder if the input (I4, the parport pin) is supposed to be "I filled it now" and 20 minutes later something is supposed to happen
[02:34:29] <cradek> (although poking iocontrol.lube_level doesn't seem to do anything)
[02:35:37] <jmkasunich> have you looked at http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Sample_HAL_And_ClassicLadder
[02:35:39] <jepler> so maybe it should be NC, the way I've got it hooked into VCP -- click the button to simulate the "lube refilled" signal rather than the other way around?
[02:36:00] <cradek> emc_lube_level
[02:36:00] <cradek> Returns the lubricant level sensor reading as "ok" or "low".
[02:36:22] <cradek> if (emcStatus->io.lube.level == 0) {
[02:36:22] <cradek> Tcl_SetResult(interp, "low", TCL_VOLATILE);
[02:36:30] <jmkasunich> the paragraph right before section 4 might explain what Ray had in mind with that rung
[02:37:07] <cradek> tkemc never calls emc_lube_level though
[02:37:12] <cradek> :q
[02:37:17] <cradek> oops
[02:38:10] <jepler> is that a digraph for the little-known german character "sideways snail umlaut"?
[02:39:00] <cradek> no it's an emoticon for a cat with tuna on his nose
[02:41:59] <jepler> I'm afraid I don't quite see it that way
[02:42:25] <jmkasunich> maybe a cat about to lick its nose?
[02:42:28] <skunkworks> jmkasunich: people said you wouldn't be too impressed with this little one ;) http://www.electronicsam.com/images/KandT/servostart/permotor.JPG (ok - one person)
[02:42:44] <jmkasunich> I saw that
[02:43:00] <jmkasunich> I'm impressed by the huge peak to continuous ratio
[02:43:18] <skunkworks> the rotor seems to be only about 2 inches at the most
[02:44:08] <skunkworks> turning it over by hand - it feels like nothing is attached to the shaft ;)
[02:49:06] <CIA-5> 03jepler 07HEAD * 10emc2/configs/demo_sim_cl/ (demo_sim_cl.vcp demo_sim_cl.hal estop.vcp): rename vcp file; convert lube-up to a toggle button
[09:18:46] <alex_joni> hi Dallur
[09:26:19] <anonimasu> morning
[09:43:25] <alex_joni> hey anders
[09:44:20] <anonimasu> what's up?
[10:05:09] <alex_joni> lots :)
[10:06:07] <alex_joni> * alex_joni is playing with 40mm sheets now
[10:07:31] <alex_joni> metal sheets that is :D
[10:39:17] <anonimasu> hehe
[10:39:32] <anonimasu> alex_joni: you are crazy calling that kind of stuff "sheet"
[10:40:04] <alex_joni> anonimasu: if it's in 2x6m sizes.. yes
[10:40:25] <anonimasu> "slab" :D
[10:40:31] <alex_joni> slab?
[10:40:40] <anonimasu> more like it..
[10:40:53] <anonimasu> actually you are right it's still sheet..
[10:40:53] <alex_joni> yeah
[10:41:03] <alex_joni> I've seen sheets in 80mm
[10:41:04] <alex_joni> and thicker :D
[10:41:22] <alex_joni> even 200mm+ .. but I won't call those sheets :P
[10:43:13] <anonimasu> :D
[11:02:18] <alex_joni> http://www.theregister.co.uk/2006/11/03/urinal_auction/
[11:38:15] <anonimasu> :9
[13:02:55] <alex_joni> morning ray
[13:04:03] <rayh-smithy> Hi alex
[13:06:58] <rayh-smithy> Hi Jymmm
[13:07:45] <Jymmm> hey ray, how ya doin?
[13:19:35] <alex_joni> morning Jymmm
[13:33:46] <Guest244> hello everybody
[13:33:56] <rayh-smithy> Hi
[13:36:45] <rayh-smithy> rayh-smithy is now known as rayh
[13:41:55] <Guest244> somebody could help me in core-servo.hal
[13:43:32] <alex_joni> Guest244: ask away
[13:44:22] <Guest244> my nick is Didier usually
[13:44:26] <anonimasu> brb
[13:46:18] <Guest244> why when i have linksp Xpos-cmd <= axis.0.motor-pos-cmd and linksp Apos-cmd <= axis.0.motor-pos-cmd
[13:46:31] <Guest244> only the last is available ?
[13:47:27] <alex_joni> no, both should work
[13:48:20] <Guest244> when i see in hal configuration, i obtain only one
[13:48:40] <alex_joni> only one of what?
[13:49:02] <alex_joni> axis.0.motor-pos-cmd if the command coming out of emc2
[13:49:15] <alex_joni> in your setup it goes to both Xpos-cmd and Apos-cmd
[13:49:17] <Guest244> i see axis 0 motor-pos-cmd
[13:49:26] <alex_joni> Guest244: of course
[13:49:39] <Guest244> i have only => Xpos-cmd
[13:50:51] <Guest244> and not => Xpos-cmd => Apos-cmd
[13:51:35] <alex_joni> Guest244: Xpos-cmd is a signal
[13:51:42] <Guest244> ok
[13:51:55] <Guest244> Apos-cmd too
[13:52:36] <alex_joni> in your example you would see axis.0.motor-pos-cmd linked to Xpos-cmd and Apos-cmd
[13:52:44] <alex_joni> but halcmd and halshow can't show that afaik
[13:53:23] <Guest244> it's to say, effectively the connection is ok, but i can't see it ?
[13:53:59] <Guest244> afaik ?
[13:55:58] <skunkworks> As Far As I Know
[13:57:15] <Guest244> thank you skunkworks for the frenchie
[13:58:37] <skunkworks> no problem.
[13:59:10] <alex_joni> Guest244: halcmd show
[13:59:13] <alex_joni> it should have a section for signals
[13:59:17] <alex_joni> there you should see both
[13:59:41] <Guest244> i try
[13:59:45] <alex_joni> Guest244: take the max-nc configuration, or any other 4-axis configuration and start from there.. much easier
[14:00:02] <Guest244> thanks
[14:00:17] <skunkworks> /nick <name>
[14:00:24] <skunkworks> changes your name
[14:01:47] <Guest244> but Didier is already in use ?
[14:05:30] <skunkworks> some one has it registerd I guess. Can you use an alternate?
[14:05:48] <skunkworks> skunkworks is now known as didier_
[14:05:54] <didier_> didier_ is now known as skunkworks
[14:05:54] <alex_joni> then you need to register it next time
[14:06:08] <alex_joni> alex_joni is now known as _
[14:06:27] <_> _
[14:07:20] <_> _ is now known as ^
[14:07:31] <^> this is fun
[14:07:38] <^> ^ is now known as alex_joni
[14:07:45] <skunkworks> goof ball
[14:07:48] <skunkworks> ;)
[14:10:58] <alex_joni> * alex_joni kicks skunkworks
[14:13:40] <alex_joni> #EMC You need to be a channel operator to do that
[14:28:04] <skunkworks> alex_joni: I played with that ge servo last night - pretty cool.. Next I need to close the loop.
[14:30:41] <skunkworks> alex_joni: Your not an operator?
[14:30:59] <Guest244> there is a configuration 4 axes with servo ?
[14:34:39] <skunkworks> Guest244: what is your hardware?
[14:35:05] <Guest244> Motenc
[14:35:48] <Guest244> Guest244 is now known as _Didier
[14:42:03] <_Didier> there is a problem whit this hardware ?
[14:43:49] <skunkworks> Not that I know of. I have no experience with the motenc card. (actually very litte experience with servos for that matter)
[14:44:29] <_Didier> i have 3 motors, and i try to do a gantry XXY with motenc configuration
[14:51:32] <anonimasu> logger_emc: bookmark
[14:51:32] <anonimasu> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2006-11-07.txt
[14:54:12] <anonimasu> hey apha
[14:54:17] <anonimasu> alpha..
[14:54:37] <A-L-P-H-A> hi
[15:01:21] <anonimasu> I've got new tooling today :)
[15:32:30] <_Didier> bye everybody, and thanks
[16:02:41] <_Didier> hi again
[16:02:57] <_Didier> trivkin is the solution for a gantry ?
[16:13:22] <_Didier> sorry bye
[16:13:22] <Sturgge> I'm planning to use EMC on a old computer, but i'm not sure if EMC will work with it. What kind of computer it needs how fast and how big harddrive?
[16:13:54] <cradek> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Hardware_Requirements
[16:14:28] <Sturgge> ok, thanks
[16:14:34] <alex_joni> Sturgge: cradek is an automated bot that searches the wiki and displays relevant pages :D
[16:14:39] <alex_joni> * alex_joni is kidding
[16:17:25] <cradek> no I'm just a guy who helps write wiki pages that people don't find
[16:18:01] <alex_joni> you didn't write that .. did you?
[16:18:04] <alex_joni> :-P
[16:18:18] <cradek> part of it
[16:25:04] <alex_joni> cradek: just playing..
[17:48:17] <jepler> cradek: that "glitch" in the ladder editor I mentioned wasn't a glitch. Some other rung of the ladder has the function of constantly setting the duration of that particular counter to 5s (or 10s if some condition is true)
[17:48:43] <cradek> ah, cool
[17:48:55] <cradek> it would be nice if there weren't any glaring problems to start with
[17:49:06] <jepler> alex said he'd found a crash :(
[17:49:14] <cradek> LALALALA
[17:49:18] <jepler> with load or save or something
[17:49:36] <alex_joni> jepler: let me try on the latest
[17:52:11] <alex_joni> jepler: no issues now
[17:52:26] <alex_joni> but I don't want to mess much with it, cause I'd probably find a ton of bugs
[18:34:03] <skunkworks> you guys are awsome :)
[18:34:11] <skunkworks> awesome
[18:49:33] <alex_joni> skunkworks: safety issue: pc hangs, parport freezes, forwards sticks to 1
[18:49:45] <alex_joni> motor turns CW at max speed
[18:50:12] <alex_joni> maybe not with your h-bridge, but there might be some that do that
[18:52:51] <skunkworks> Good point. but you are right - with my h-bridge it would run until the bootstrap cap dischared and then shut off. (about 5 seconds at the most)
[18:53:55] <skunkworks> granted - a lot can happen in 5 seconds ;)
[18:54:29] <alex_joni> at full speed
[18:54:53] <skunkworks> right
[18:55:51] <skunkworks> isn't that what you would set up a 'charge pump' for? (external circuit that would keep track that the computer wasn't locked up)
[18:56:47] <alex_joni> yup
[18:57:01] <alex_joni> and a few other safety features :D
[18:57:30] <A-L-P-H-A> back from the docs.
[18:57:50] <A-L-P-H-A> I'm so far healthy, but don't know what STDs I may have if any.
[18:58:33] <skunkworks> why not get tested?
[18:58:47] <A-L-P-H-A> bloodwork is in.
[18:58:49] <A-L-P-H-A> 2 weeks
[18:59:28] <A-L-P-H-A> Actually checking hapititus... but I don't show any signs of problems, so doubtful.
[19:02:25] <alex_joni> http://romaniainedit.3xforum.ro/img/pics/romaniainedit.3xforum.ro/ok_122680.jpg
[19:05:50] <A-L-P-H-A> that is ONE FAT PUSSY.
[19:06:15] <A-L-P-H-A> seriously, that cat I give 2 months before it dies of obesity.
[19:06:34] <LawrenceG> "girl found crushed by cat"
[19:06:42] <A-L-P-H-A> cat = pussy
[19:06:50] <A-L-P-H-A> better headline grabber.
[19:06:59] <A-L-P-H-A> "girl found crushed by pussy".
[19:07:11] <A-L-P-H-A> you'd read that more than "girl found crushed by cat"
[19:07:22] <A-L-P-H-A> gotta use keywords to grab people's attention.
[19:07:38] <LawrenceG> "girl found with large pussy?"
[19:08:18] <A-L-P-H-A> not bad.
[19:08:24] <A-L-P-H-A> "girl w/giant pussy!"
[19:08:34] <LawrenceG> good morning from the west coast of NA
[19:08:43] <A-L-P-H-A> uh
[19:08:54] <A-L-P-H-A> yeah
[19:10:58] <skunkworks> lawrenceg: how is the 3 phase controller going?
[19:11:27] <alex_joni> http://romaniainedit.3xforum.ro/img/pics/romaniainedit.3xforum.ro/ok_124482.jpg
[19:11:37] <alex_joni> that's a cute pussy
[19:11:50] <LawrenceG> not very fast... ended up using some brush servos for the current project...
[19:12:17] <LawrenceG> need to get out to the shop and make some motor mounts and get some iron moving
[19:12:56] <A-L-P-H-A> http://today.reuters.com/news/articlenews.aspx?type=healthNews&storyid=2006-11-06T181057Z_01_COL663143_RTRUKOC_0_US-CIRCUMCISION-STD.xml&src=rss Circumcision appears to reduce STD risk... well, I'm cut. but not getting enough to be at significant risk to get an STD.
[19:13:01] <skunkworks> Thats ok.. I hooked a decent sized servo up to my h-bridge last night. pretty cool (still running as a spindle) hope to mount the encoder tonight and play with pid.
[19:13:26] <LawrenceG> I would like to get back to the 3 phase project, as the motors/encoder I have are very nice
[19:14:11] <A-L-P-H-A> alex_joni: wtf is that? in the image? it looks like a marsupial
[19:15:08] <skunkworks> I have posted this picture about 5 times now - but this is the servo we found on a shelf ;) http://www.electronicsam.com/images/KandT/servostart/permotor.JPG
[19:15:31] <alex_joni> A-L-P-H-A: they claim it's cat
[19:15:53] <A-L-P-H-A> looks like a marsupial... from like Madagascar.
[19:16:27] <LawrenceG> cool.... I would like to find a good cheap high speed spindle....
[19:16:44] <LawrenceG> so far, a trim router is what I am planning to use
[19:17:09] <A-L-P-H-A> I've got nothing for a highspeed router.
[19:17:10] <LawrenceG> My current mill tops out at about 3000rpm and mostly I make PCB's
[19:17:12] <A-L-P-H-A> I would love to have something.
[19:17:29] <A-L-P-H-A> LawrenceG: mechanical etching?
[19:17:35] <LawrenceG> yea...
[19:17:43] <A-L-P-H-A> doesn't it gum up?
[19:18:20] <LawrenceG> no... most of the problems are grinding my own cutters from broken pcb drills
[19:18:26] <A-L-P-H-A> oh
[19:18:31] <A-L-P-H-A> brb...
[19:18:38] <A-L-P-H-A> ahh,... nm
[19:18:51] <A-L-P-H-A> I can't decided on anything.
[19:18:58] <A-L-P-H-A> I can't even decide to reboot my machine into windows.
[19:19:00] <LawrenceG> I have to cut about 5ipm because of the slow spindle.....
[19:19:00] <A-L-P-H-A> GAH!
[19:19:08] <A-L-P-H-A> k, reboot
[19:20:00] <skunkworks> LawrenceG: I am running a 'rotozip' style spidle on the gantry. works well for circuit boards
[19:21:47] <LawrenceG> picture? model?
[19:22:24] <skunkworks> hmm - have to look - I think it is something we got from sears
[19:23:23] <a-l-p-h-a> back, and what fun!
[19:23:28] <LawrenceG> ok.... how are bearings standing up? Some of my boards take an hour to route
[19:24:14] <alex_joni> good night all
[19:24:22] <LawrenceG> cheers
[19:26:47] <a-l-p-h-a> wth?
[19:26:48] <a-l-p-h-a> alex_joni: ? what time is it?
[19:26:59] <a-l-p-h-a> isn't it like only 10pm??
[19:31:12] <skunkworks> LawrenceG: no issues yet. I don't know how much time we have on it. it is similar to this http://www.sears.com/sr/javasr/product.do?cat=Portable+Power+Tools&pid=00917244000&vertical=TOOL&subcat=Rotary+%26+Spiral+Cutting+Tools&BV_UseBVCookie=Yes
[19:31:45] <skunkworks> I jammed it into the table once so far also ;)
[19:34:48] <LawrenceG> i hate it when that happens
[19:35:44] <a-l-p-h-a> I have limit switches, yet I choose not to use them.
[19:35:52] <a-l-p-h-a> like mount them.
[19:35:54] <a-l-p-h-a> I'm dumb.
[19:36:07] <a-l-p-h-a> I should probably put them on, but I feel like napping instead.
[19:36:56] <LawrenceG> yea... I have done a couple of pcb projects where Z got out of whack and tried to cut a trace right through the PCB... not pretty
[19:43:33] <skunkworks> This looks more like it http://cgi.ebay.com/SEARS-CRAFTSMAN-Rotozip-Type-Rotary-Tool-Router_W0QQitemZ7563627567QQihZ017QQcategoryZ29528QQssPageNameZWD1VQQrdZ1QQcmdZViewItem#ebayphotohosting
