#emc | Logs for 2005-09-29

[00:12:25] <bosone> hi paul :)
[00:17:08] <paul_c> evening..
[00:33:14] <paul_c> Is zwelch awake ?
[00:44:35] <Jymmm> I'm gonna have to pay a fortune for a relay =(
[01:07:03] <lilo> [Global Notice] Hi all. We're experiencing problems with a main rotation server, and we've removed it from the rotation. It may flap a bit while we kill it out, the site is experiencing internet connectivity problems.
[01:29:55] <jcolley> 'lo all
[01:33:08] <jcolley> too late to catch paul again?
[01:39:35] <Jymmm> and les too
[01:39:41] <jcolley> figure
[01:39:41] <Jymmm> les_away wake up
[01:39:51] <Jymmm> he might be here
[01:39:53] <jcolley> what time are they normally around?
[01:39:57] <Jymmm> * Jymmm pokes les_away
[01:40:15] <Jymmm> varioes
[02:04:38] <jcolley> so just how usable is emc2 right now
[02:06:06] <Jacky^> bye bye baby ..
[02:06:09] <Jacky^> G night
[02:56:02] <les_away> I got poked...huh?
[02:58:12] <les_away> well.everyone in Europe is asleep and everyone in the Americas is watching tv?
[02:58:59] <les_away> Don't bother...I flipped through the hundreds of channels...all garbage
[02:59:29] <les_away> and in the 50% of time it's not commercials?
[03:00:00] <les_away> commercials stream on the bottom of the screen during programs.
[03:00:11] <les_away> commercial inflation it seems
[03:00:34] <cradek> I think it's funny that you still get that after paying for the TV service
[03:00:55] <les_away> frog/slowly boiling water thing I guess
[03:01:15] <les_away> yeah we pay to watch em!
[03:01:19] <cradek> not for me - I ditched cable several years ago
[03:01:32] <les_away> I have direct tv
[03:01:34] <cradek> waste of money, waste of time, waste of brain cells
[03:01:40] <les_away> yeah
[03:01:54] <les_away> sure is
[03:26:03] <Jymmm> les_away wastes brain cells in the music room every night.
[11:14:52] <Jacky^> morning
[13:13:47] <les_away> morning all
[13:14:07] <les_away> les_away is now known as les
[13:31:36] <paul_c> paul_c has changed the topic to: Welcome to the Enhanced Machine Control forum - Support and development of a linux based CNC control. | Home page www.linuxcnc.org | Regular Developer's meetings every Sunday between 14:00 & 18:00 GMT | General linux discussions and support the rest of the week. | Final release BDI-4.30 | Six people have ops capabilities - Lucky dip !

[16:36:33] <alex_joni> cradek: chris, you there?
[16:36:57] <ValarQ> hello mr Joni
[16:37:10] <alex_joni> hello captain
[16:53:46] <ValarQ> didn't i tell you i only was a sergeant?
[16:53:55] <alex_joni> so?
[16:54:05] <alex_joni> you might have improved your status till now
[16:54:09] <alex_joni> or you should :D
[16:54:19] <ValarQ> should is a better word :)
[16:54:47] <alex_joni> shoulda woulda
[17:11:50] <cradek> alex_joni: now I am
[17:31:59] <alex_joni> hey rayh
[17:32:08] <rayh> Hi alex.
[17:32:27] <alex_joni> what's new?
[17:36:47] <rayh> Trying to get a 3com modem to work. Not a winmodem but still won't communicate.
[17:37:38] <alex_joni> external?
[17:38:06] <CIA-8> 03paul_c 07bdi-4_30 * 10emc2/src/ (39 files in 8 dirs):
[17:38:07] <CIA-8> This make up the final round of commits. The code compiles and runs on the current BDI-4.30 build.
[17:38:07] <CIA-8> Except for the misclib sources (which are not called by any standard EMC functions), this represents the code base for the final BDI-4 release derived from the original EMC1 code.
[17:38:37] <rayh> PCI
[17:38:57] <alex_joni> treat it with an external case
[17:39:03] <alex_joni> * alex_joni would suggest the trashcan ;)
[17:39:31] <rayh> They worked under 2.4 kernels fine. 2.6 is a known problem.
[17:39:46] <rayh> Need to compile in ppp rather than module.
[17:40:14] <alex_joni> I see
[17:40:48] <rayh> bummer. will suggest to the customer that they purchase a $39 external
[17:42:24] <rayh> Did you get a larger prototype of the triangular laser cutter going?
[17:43:23] <alex_joni> nah.. still thinking of it :(
[17:43:35] <alex_joni> err.. make that "dreaming"
[17:45:22] <rayh> I like the concept a lot.
[17:48:07] <alex_joni> huh.. how did that happen?
[17:49:13] <rayh> I've thought of building a flame cutter using hexapod kinematics and cables.
[17:49:27] <alex_joni> not that ;) I know that
[17:49:34] <alex_joni> [19:24] -ChanServ- You have been added to the access list for #emc with level [10]
[17:50:12] <rayh> Connect winches near the ceiling of the building and store the cables out of the way.
[17:50:34] <alex_joni> you know what would work ok for that?
[17:50:39] <alex_joni> using giant spiders
[17:50:41] <rayh> level(10) who me?
[17:50:48] <alex_joni> produce the cable as it's needed
[17:50:53] <alex_joni> no.. me ;)
[17:51:11] <rayh> Oh. I know nothing!
[17:55:10] <ValarQ> hello Paul
[17:55:28] <paul_c> Evening
[17:55:44] <alex_joni> hey paul
[17:55:53] <alex_joni> is it proper to say electrovalve?
[17:56:57] <paul_c> thermionic device
[17:57:10] <alex_joni> really?
[17:57:44] <paul_c> valves are vintage heaters...
[17:58:33] <alex_joni> ok.. how do you call the thingie that lets air through?
[17:58:44] <rayh> solenoid?
[17:58:52] <alex_joni> solenoid valve?
[17:58:53] <alex_joni> :D
[17:59:28] <rayh> often "air solenoid" or "hydraulic solenoid"
[17:59:36] <paul_c> pnuematic valve or somenoid
[17:59:38] <alex_joni> ok.. solenoid
[17:59:42] <paul_c> pnuematic valve or solenoid
[17:59:56] <alex_joni> ty
[18:00:14] <alex_joni> paul_c: might get it right the third time ;)
[18:00:29] <paul_c> spelling is a bit off today..
[18:00:36] <alex_joni> heh
[18:00:38] <alex_joni> I guess so
[18:02:28] <alex_joni> is 4.30 out there for mirroring?
[18:02:55] <paul_c> wait till the md5 is up.
[18:03:00] <alex_joni> ok
[18:04:13] <paul_c> 640012K
[18:04:33] <alex_joni> sounds reasonable
[18:17:17] <alex_joni> * alex_joni will be online later
[18:17:20] <alex_joni> bye guys
[18:17:34] <paul_c> later.
[21:00:56] <Jacky^> hello :)
[21:05:57] <Jacky^> anyone knoe the EC servomotor brand ?
[21:07:51] <Jacky^> my cousin give me a motor , he has 5-6 kg :\
[21:07:59] <Jacky^> can't find the datasheet ..
[21:08:17] <Jacky^> it*
[21:09:05] <Jacky^> EC permanent magnet servo motor, model 0703
[21:10:38] <Jacky^> hi Jymmm
[21:12:14] <Jymmm> hi
[21:12:39] <Jacky^> Jymmm: any idea about Electro Craft Corporation ?
[21:12:45] <Jymmm> nope
[21:12:46] <Jacky^> it is in US ?
[21:12:51] <Jacky^> ok
[21:13:15] <Jacky^> i'm looking for a datashet
[21:18:23] <Jacky^> 10cm diameter, 18 lenght servo motor :\
[21:18:34] <Jacky^> * Jacky^ ghghg
[21:18:38] <Jacky^> :)
[21:19:25] <Jacky^> its a rock, not a motor
[21:19:53] <Imperator_> have some electro craft servos here
[21:20:07] <Jacky^> Imperator_: wow ..
[21:20:18] <Jacky^> i never seen a motor like that
[21:20:23] <Jacky^> incredible ..
[21:20:36] <Jacky^> im looking for a datasheet ..
[21:20:50] <Jacky^> seem hard to find
[21:21:15] <Imperator_> what is taht special about that servos ?
[21:21:44] <Jacky^> no, idea.. something like voltage, current ?
[21:22:10] <Jacky^> i tried to short + - wire togheter it dont turn !
[21:22:30] <Jacky^> with 12V seem have a great torque
[21:22:40] <Jacky^> but i dnot know other..
[21:23:15] <icee> don't short a motor phase together
[21:23:26] <icee> you're acting as a brake then
[21:23:29] <Jacky^> withou suply i mean
[21:23:52] <icee> yes, without a supply, you're still acting as a brake
[21:23:53] <Jacky^> just to test the magnet inside ..
[21:24:03] <Jacky^> ok
[21:24:21] <Jacky^> understood :)
[21:24:40] <icee> it should turn relatively freely with none of the wires touching tho
[21:24:53] <Jacky^> infact, it does
[21:26:09] <Jacky^> the shaft is abou 15 mm
[21:26:14] <Jacky^> damn motor ..
[21:26:16] <Jacky^> :P
[21:26:42] <Jacky^> seem a monster
[21:27:26] <Jacky^> so.. ther's not much to know about voltage and current ?
[21:27:42] <Jacky^> i could try with a variable supply
[21:29:39] <icee> if you have a current limited supply, you could see what level the motor gets slightly warm at
[21:29:45] <icee> and what the voltage across the coil is
[21:29:57] <Jacky^> yeah, ive it
[21:30:11] <icee> you want to turn it up very slowly though because there's substantial thermal inertia in a motor
[21:30:16] <Jacky^> which voltage should be the high limit ?
[21:30:24] <Jacky^> for a generic servo
[21:30:37] <Jacky^> i've no idea..
[21:30:37] <icee> don't worry about voltage-- worry about current
[21:30:45] <Jacky^> oh .. ok
[21:34:02] <Imperator_> and don't supply the Tacho, if it has one !!
[21:34:14] <Jacky^> ouch
[21:34:21] <Jacky^> there's no taco here ..
[21:34:29] <Jacky^> no encoder too
[21:34:36] <Jacky^> just the motor :)
[21:34:44] <Jacky^> + - wire
[21:35:26] <Jacky^> the test i made is with 12 V battery 1 amp current
[21:35:55] <Jacky^> seem turn slow but with a big torque
[21:40:20] <Imperator_> ok
[21:40:34] <Imperator_> have some with Tacho
[21:40:41] <Imperator_> smal ones
[21:45:21] <Jacky^> this have 2 big screw to change the brush
[21:57:44] <Imperator_> my servos have four
[22:00:00] <Jacky^> mmhh ..
[22:00:11] <Jacky^> id prefer 2
[22:00:19] <Jacky^> or nothing .. better :)
[22:01:10] <les> hi
[22:01:20] <les> wasted day for me!
[22:01:26] <Jacky^> hi les
[22:01:30] <Jacky^> :D
[22:01:51] <les> I was cutting some very fine threads on a resonator on the lathe.
[22:02:13] <Jymmm> les you too huh? I've already fixed a mailbox on one domain, and a forum on another.
[22:02:25] <les> I accidentally bumped into the cross slide crank and moved it
[22:02:38] <Jacky^> les: aarggh
[22:02:46] <les> next pass...zipppppp.....threads peeled right off!
[22:02:48] <les> grr
[22:02:51] <Jymmm> les Got Beer? and lots of it!
[22:02:58] <les> yeah.
[22:03:00] <les> then...
[22:03:16] <les> I dropped one of the other resonators and bent it
[22:03:23] <les> can be repaired
[22:03:25] <les> but
[22:03:30] <Jymmm> * Jymmm hands les a keg
[22:03:39] <les> I'm running negative for today.
[22:03:55] <Jacky^> i succesfull get running 2 steppers with printer-board hacked today :)
[22:04:09] <Jacky^> i need to do the same on another, to get 4 axis :P
[22:04:12] <Jymmm> les seems to be going around today.
[22:04:42] <les> heh
[22:04:51] <Jacky^> and .. i will get my small PCB mill machine :D
[22:05:03] <Jymmm> les : you , me, jacky
[22:05:05] <les> those are handy
[22:05:43] <les> I have to do some tronics....customer requested a change in the encoder functions
[22:06:27] <les> have to throw some band gap diodes in there...and a couple comparators
[22:07:00] <les> and a multiplexer
[22:07:12] <les> or something
[22:07:58] <les> I'm not going to design anything today...i'll just mess it up
[22:10:25] <les> I am going to design a way to empty this can of beer.
[22:11:13] <les> ; )
[22:13:45] <Jacky^> its time to made the wineeeeee
[22:13:52] <les> heh
[22:13:57] <Jacky^> the beer is died
[22:14:02] <Jacky^> :)
[22:14:30] <Jacky^> beer is ok in the summer
[22:15:31] <les> oh and my pet bug died!
[22:15:35] <les> the mantid
[22:15:47] <Jacky^> :\
[22:15:58] <les> I fed him a big grasshopper and he ate it
[22:16:13] <Jacky^> ah
[22:16:14] <Jacky^> :)
[22:16:17] <les> but later stopped moving....normal for a mantid
[22:16:28] <les> but he did not move at all...
[22:16:37] <les> then his head fell off!!!
[22:16:45] <Jacky^> hehe
[22:16:53] <les> I think he has some issues...
[22:16:59] <les> haha
[22:17:12] <Jacky^> :)
[22:18:42] <LawrenceG> when is the funeral? Are international morners invited?
[22:19:07] <Jacky^> hi LawrenceG :)
[22:19:26] <les> heh...on the mantid group I am in people get quite upset...but...bugs die inthe fall!
[22:20:07] <LawrenceG> Jacky^, hey... good work on hacking the printer board... it is running with emc2 now in quaduture mode?
[22:20:31] <Jacky^> LawrenceG: nope.. not at all ..
[22:20:45] <LawrenceG> what is the problem?
[22:20:58] <Jacky^> i just used stepgen [2] to get it running
[22:21:14] <LawrenceG> that works
[22:21:21] <Jacky^> with all pin i* for all current
[22:21:32] <Jacky^> yeah, work fine enough :P
[22:21:47] <LawrenceG> are they strong enough for your project?
[22:22:03] <Jacky^> sure,
[22:22:12] <Jacky^> just move a mini-mill
[22:22:20] <Jacky^> or some pen on a pcb
[22:22:47] <Jacky^> i found some difficult to get 6 pin on genstep
[22:22:59] <Jacky^> it seem have 5 for default..
[22:23:10] <Jacky^> ops
[22:23:13] <Jacky^> stepgen*
[22:23:15] <Jacky^> :)
[22:23:52] <Jacky^> i'm just playng to learn something ..
[22:24:19] <LawrenceG> great.... well my next chore is to rewrite the audio driver for a piece of ham radio software.. need to move it from oss api to the alsa api because the oss emulation drivers for my card are broken {
[22:24:39] <Jacky^> wow
[22:25:02] <LawrenceG> hey with open source if you want it working... it CAN be fixed!
[22:25:30] <Jacky^> are you an amateur radio ?
[22:26:19] <LawrenceG> yup callsign ve7it ... then I would like to built a variable speed spindle drive for some tread mill motors I bought
[22:26:33] <LawrenceG> brb... someone at the door
[22:26:38] <les> lawrence is an amateur radio...he has a cubical quad growing out of his head.
[22:26:45] <Jacky^> wow
[22:26:48] <les> haha
[22:26:52] <Jacky^> i was having a quad too
[22:27:02] <Jacky^> for 2-3 years..
[22:27:05] <Jymmm> * Jymmm has a J-Pole
[22:27:15] <Jacky^> i've postacard from 27 country
[22:27:32] <Jacky^> also from Faroe Island !
[22:27:42] <Jacky^> and one.. from New Zealand
[22:27:49] <Jacky^> incredible
[22:28:06] <Jacky^> new zealand is the other world from here ..
[22:28:10] <Jacky^> :D
[22:28:20] <Jacky^> someone from indonesia
[22:29:04] <Jacky^> ah.. dominican republic too :P
[22:29:24] <Jacky^> but i was an 'abusive' ..
[22:29:30] <Jacky^> i'm an SWL
[22:29:50] <Jacky^> ive not license
[22:29:53] <les> the only radio I do is in aircraft
[22:30:02] <Jacky^> K roger :)
[22:30:06] <les> haha
[22:30:08] <Jacky^> break break
[22:30:18] <Jymmm> cq cq cq dx
[22:30:22] <Jacky^> haha
[22:30:37] <Jacky^> was funny
[22:31:26] <les> We can't do "roger"...FAA requires us to read back air traffic control instructions
[22:31:41] <Jacky^> alex_joni: g evening
[22:31:51] <alex_joni> hey Jacky^
[22:32:07] <Jacky^> alex_joni: ive a question for you
[22:32:09] <Jacky^> :)
[22:32:11] <alex_joni> shoot
[22:32:25] <Jacky^> i want to connect a phisical encoder to emc2
[22:32:29] <Jacky^> just to test
[22:32:46] <alex_joni> right
[22:32:50] <Jacky^> its ok a simple homebuilt circuit ?
[22:32:54] <alex_joni> sure
[22:33:05] <Jacky^> some phototransistor/led ?
[22:33:12] <alex_joni> an encoder shouldn't have enough power to kill a parport
[22:33:22] <alex_joni> basicly yes, but also a lot of logic
[22:33:25] <Jacky^> nah .. TTL
[22:33:30] <Jacky^> yeah ..
[22:33:44] <alex_joni> usually you have 3 channels on the encoder
[22:33:59] <alex_joni> A/_A B/_B and Z
[22:34:00] <Jacky^> I know ..
[22:34:07] <Jacky^> Index
[22:34:13] <alex_joni> Z=index
[22:34:16] <Jacky^> right ?
[22:34:18] <Jacky^> yeah
[22:34:20] <alex_joni> and the other 2 are quadrature
[22:34:58] <Jacky^> 90� out phase ..
[22:35:12] <Jacky^> if i remember well
[22:35:18] <alex_joni> A and not-A
[22:35:19] <alex_joni> right
[22:35:29] <icee> not A?
[22:35:37] <alex_joni> A inverted
[22:35:38] <icee> that would be 180 degrees.
[22:35:44] <icee> And wouldn't tell you what way it's turning.
[22:35:49] <alex_joni> right
[22:36:02] <alex_joni> but there are 2 pairs
[22:36:04] <alex_joni> A nd B
[22:36:05] <icee> Quadrature is 90 degrees out of phase-- gray code
[22:36:09] <Jacky^> 90� respect to the other..
[22:36:13] <Jacky^> ?
[22:36:15] <alex_joni> and not A with not B
[22:36:19] <alex_joni> right
[22:36:25] <Jacky^> ok
[22:36:33] <icee> 00, 01, 11, 10, 00 CW, 00, 10, 11, 01, 00 CCW
[22:36:58] <Jacky^> tomorrow i will try :)
[22:37:18] <Jacky^> alex_joni: how are the things going there ?
[22:37:25] <alex_joni> Jacky^: hook up power to the encoder
[22:37:31] <Jacky^> yeah
[22:37:33] <alex_joni> and turn it, connect a scope to A nd B
[22:37:37] <alex_joni> A and B
[22:37:44] <alex_joni> and see them toggle
[22:38:00] <Jacky^> ok
[22:38:10] <alex_joni> if you find a pair of 90 degs signals then you're set
[22:38:57] <Jacky^> thanks
[22:39:02] <Jacky^> :)
[22:40:56] <alex_joni> Jacky^: yeah, pretty ok around here. going home tomorrow
