#emc | Logs for 2005-08-17

[00:04:21] <Jymmm> I said logger off, not bugger off!
[00:34:07] <gezr> I just dont have much to say
[00:34:54] <gezr> I do wonder if the guy with the chatter problem got it fixed
[00:35:02] <gezr> he is right about the temp of his bp spindle
[00:35:49] <gezr> and this .040 doc is troubling, but it may just suit his application
[00:54:42] <Jacky^> cant find a schematic online for 5 phase stepper motors :(
[00:55:13] <gezr> they tend to require a 5 phase drive
[00:55:27] <gezr> I looked into them, but gave up, vextra right?
[00:55:53] <Jacky^> yeah
[00:56:25] <gezr> I think they tend to be a packaged deal, I may be wrong but I really think they are a drive/motor combo
[00:57:00] <Jacky^> it seem to be used for some application only, like potitioning telescope
[00:57:04] <gezr> ill try helping you search, you loking for the drive right?
[00:57:18] <Jacky^> yeah
[00:57:43] <gezr> http://www.pmsupplies.com/Tamagawa_AU9112.html
[00:57:52] <gezr> low price drive, havent seen a price yet though
[00:58:40] <Jacky^> yeah, thanks
[00:58:54] <Jacky^> i'm not sure abut the current..
[00:59:28] <Jacky^> this model i've is 2.6A/phase 0.67 ohm
[00:59:38] <Jacky^> 0.72 deg/step
[01:00:19] <Jacky^> seem a nice motor
[01:01:35] <gezr> you would probably want a matching drive from vextra for it then
[01:01:53] <Jacky^> probably..
[01:02:21] <gezr> I think they are pretty expensive things though
[01:02:26] <Jacky^> i bought it for E. 15 (used)
[01:02:42] <Jacky^> 7 mounths ago..
[01:03:09] <Jacky^> bah..
[01:03:32] <Jacky^> anyway this is not so good for cnc use
[01:03:57] <Jacky^> i think ..
[01:06:38] <gezr> hmm, hold on
[01:06:47] <gezr> http://www.orientalmotor.com/in_motion/july_2004.htm
[01:08:12] <Jacky^> nice page
[01:08:17] <gezr> the idea behind the 5 phase is uber
[01:08:41] <gezr> if you could find a good drive for it, then heck yeah, I bet one could be made
[01:08:46] <gezr> with that diagram pretty much
[01:09:08] <gezr> but the logic would be a bit more involved
[01:09:13] <Jacky^> tnx :)
[01:09:43] <gezr> seems that a 5 phase motor can be more smooth
[01:09:57] <Jacky^> probably true
[01:10:17] <Jacky^> also great precision
[01:10:24] <gezr> holy crap
[01:10:26] <gezr> http://www.orientalmotor.co.jp/cgi-bin/WebObjects/UPOMStep.woa/wa/F3?typeNameId=2&modelName=CFK5913HBT&frameSize=85&seriesId=FCF2
[01:10:52] <gezr> thats also an 800+oz motor
[01:11:32] <Jacky^> cool
[01:11:51] <Jacky^> the mine is an old model ..
[01:12:08] <Jacky^> i cant find it on the web
[01:12:26] <Jacky^> A3530 - 9215
[01:12:28] <gezr> hmm, 290oz, with driver $475
[01:12:45] <Jacky^> FH7 - 1639
[01:13:18] <Jacky^> weight at lest 1 kg or more :\
[01:13:25] <Jacky^> seem very strong
[01:14:04] <gezr> any other numbers on it?
[01:14:21] <Jacky^> some other..
[01:14:34] <Jacky^> TW8 33428
[01:14:49] <Jacky^> no idea.. what these nr mean
[01:15:03] <gezr> doesnt matter what they mean, im doing a search
[01:15:45] <paul_c> cough phase drive cough
[01:15:52] <Jacky^> on top of label 5 PHASE STEPPING MOTOR
[01:15:57] <Jacky^> hey paul_c :)
[01:16:25] <Jacky^> investigating on a strange motor..
[01:16:41] <paul_c> EMC can already do four phase drive, and there is a coment in the code suggesting that it could be extended to five phase
[01:16:43] <gezr> paul_c : with 5 phase using phase drive?
[01:18:04] <Jacky^> paul_c: nice, so i could use it someday..
[01:18:31] <paul_c> Give LPG a nudge - He wrote the driver code....
[01:19:42] <Jacky^> great
[01:20:11] <paul_c> * paul_c points at LawrenceG
[01:21:11] <Jacky^> i will buy a telescope :P
[01:21:31] <Jacky^> or maybe wait a gift ;P
[01:22:12] <gezr> paul_c : typical 5phase stuff is excluded because its price range, is pretty much inline with servos?
[01:23:15] <paul_c> never used five phase steppers - Way too expensive (and I have servos...)
[01:23:16] <Jacky^> i think are made for different applications
[01:23:56] <paul_c> right.. Time for bed.
[01:24:05] <Jacky^> Gnight paul_c
[01:25:29] <gezr> les : are you watching?
[01:25:48] <Jacky^> gezr: this motor should be nice also for point sat antenna maybe
[01:26:23] <gezr> Jacky^ : oh yeah, you dont need a drive per say to make it whirl around
[01:26:44] <gezr> there are manual ways to position a stepper motor
[01:27:21] <Jacky^> yeah
[01:27:48] <Jacky^> but a gui from pc should be useful
[01:28:19] <Jacky^> to point a star, from software i mean
[01:28:25] <gezr> oh yeah
[01:28:52] <gezr> do you already have the 360deg worm wheels?
[01:29:02] <gezr> err, 360 tooth
[01:29:37] <Jacky^> for ?
[01:29:46] <gezr> the positing of the telescope?
[01:29:52] <Jacky^> nah ..
[01:30:03] <Jacky^> i don't have nothing at the moment
[01:30:08] <gezr> oh okay
[01:30:11] <Jacky^> it is just an idea
[01:30:13] <gezr> im in the same boat
[01:30:17] <Jacky^> hehe
[01:31:15] <Jacky^> Jymmm: how proceed the laptop jobs ?
[01:33:12] <Jymmm> ?
[01:33:19] <Jacky^> gezr: http://www.bbastrodesigns.com/cot/steppercircuit.html
[01:33:29] <Jacky^> Jymmm: running laptop ?
[01:33:40] <Jymmm> Jacky^: Ok, what about it?
[01:33:52] <Jacky^> how it work ?
[01:34:03] <Jymmm> Jacky^ : YOu mean w/o X?
[01:34:21] <Jacky^> already installed linux on it ?
[01:34:26] <Jymmm> Jacky^: Samba + putty + TkEMC running on windows.
[01:34:35] <Jacky^> nice
[01:35:09] <Jymmm> Jacky^: KeyStick gui running on the laptop, TkEMC running on the other laptop
[01:35:27] <Jymmm> XOVER cable between them
[01:35:48] <Jacky^> cool
[01:36:09] <Jacky^> you solved then with tkemc issue on windoze
[01:36:49] <Jacky^> if i remember well yoyu was having some issue..
[01:37:01] <Jymmm> When opening a file under TkEMC on windows, it opens up a local (nix) file system. Will just map a samba share to the proper location.
[01:37:28] <Jacky^> ah.. thats ok
[01:37:55] <Jymmm> oh and SCREEN too.
[01:38:24] <Jacky^> screen is nice
[01:38:46] <Jacky^> i always use it to run and resume remote jobs
[01:38:51] <Jymmm> I don't use it that often, but will do it's job in this respect in case the M$ box fubars.
[01:38:51] <Jacky^> very nice ;)
[01:43:15] <Jacky^> well, bedtime for me
[01:43:22] <Jacky^> night guys
[01:43:40] <Jymmm> G'Night Jacky^
[01:43:47] <Jacky^> bye
[02:00:13] <gezr> 4 auctions for some copley drives on ebay right now
[02:00:28] <gezr> one double unit for 75, the rest are below 40 each
[02:14:16] <Jymmm> copley drives?
[02:19:14] <gezr> servo drive, i have to go to bed now
[02:19:45] <Jymmm> ah, gnight
[03:09:39] <Jymmmm> Jymmmm is now known as Red70sShow
[03:09:40] <Red70sShow> Red70sShow is now known as Jymmmm
[04:05:57] <Jymmmm> Jymmmm is now known as Jymmm
[11:37:09] <Jacky^> morning
[13:43:16] <Yuga> morning
[13:43:21] <Yuga> how u doing Jacky^?
[13:44:49] <alex_joni> hello
[13:44:57] <Yuga> hello alex_joni
[13:58:51] <alex_joni> what's up?
[14:01:25] <Yuga> busy sanding down my one car
[14:01:31] <Yuga> www.myride.co.za/1.jpg
[14:01:32] <alex_joni> cool
[14:01:48] <alex_joni> * alex_joni looks
[14:01:54] <alex_joni> * alex_joni pokes paul_c
[14:02:28] <paul_c> * paul_c slaps alex_joni with a large cricket bat
[14:02:38] <alex_joni> * alex_joni ducks
[14:02:57] <Yuga> oops... wrong addy
[14:02:58] <Yuga> http://www.myride.co.za/uno/1.jpg
[14:03:20] <alex_joni> yucky
[14:03:24] <alex_joni> you running IIS?
[14:03:36] <Yuga> yep :)
[14:03:44] <Yuga> so what u think of the body kit?
[14:03:44] <alex_joni> bugger that
[14:03:48] <paul_c> Does anyone know Michael Moser ?
[14:03:52] <alex_joni> still trying to open
[14:04:10] <Yuga> but it is opening?
[14:05:59] <alex_joni> paul_c: this one http://www.michaelmoser.org/content.htm ?
[14:06:36] <alex_joni> or this one http://www.fotocommunity.de/pc/account/myprofile/26392 ?
[14:06:45] <alex_joni> Yuga: it did eventually load
[14:06:54] <alex_joni> looks ok, probably better with paint on it ;)
[14:07:01] <paul_c> http://www.smart-elektronik.at/kontakt.htm <- This one..
[14:07:10] <Yuga> lol... it has paint on it:) but i guess primer doesnt count
[14:07:49] <alex_joni> hmmm.. nice
[14:07:55] <alex_joni> emc based 6-axes controls
[14:07:56] <alex_joni> :D
[14:08:02] <Yuga> addy?
[14:08:08] <alex_joni> http://www.smart-elektronik.at/industrieelektronik.htm
[14:09:08] <Yuga> english version ??? :P
[14:09:23] <alex_joni> Yuga: start learning foreign languages
[14:09:38] <alex_joni> english will deprecate at one point or another
[14:09:54] <alex_joni> german probably too
[14:10:06] <alex_joni> but you get the exersize to switch languages ;)
[14:10:08] <paul_c> Spanish or Chinese will take over.
[14:10:20] <alex_joni> chinese is a good candidate
[14:10:28] <alex_joni> indian is also pretty wide-spread :D
[14:11:02] <alex_joni> paul_c: a bit pricey
[14:11:22] <alex_joni> 2400 Eur for a 2.8 GHz box with emc installed, TFT and keyboard/trackball
[14:13:05] <alex_joni> but it looks nice ;)
[14:13:21] <alex_joni> * alex_joni thinks about paying them a visit sometimes in the future
[14:15:06] <paul_c> methinks their mail system is borked.
[15:35:46] <alex_joni> laters everyone
[15:35:50] <alex_joni> * alex_joni goes home
[19:20:48] <alex_joni> good evening
[19:24:35] <cradek> good afternoon
[19:24:47] <alex_joni> hey chris
[19:24:50] <alex_joni> what's up?
[19:24:51] <cradek> hi
[19:24:58] <cradek> at work, not much
[19:25:06] <alex_joni> seen the new machine I'm working on?
[19:25:10] <cradek> nope
[19:25:20] <alex_joni> http://www.robcon.ro/emc/positioner/
[19:25:56] <cradek> what is it?
[19:26:02] <cradek> obviously a rotating thing
[19:26:07] <alex_joni> a 2 DOF table
[19:26:14] <alex_joni> for putting a workpiece on it
[19:26:16] <cradek> oh does the whole orange part rotate too?
[19:26:19] <alex_joni> and weld it with a robot
[19:26:21] <alex_joni> yeah :D
[19:26:26] <cradek> cool
[19:26:33] <alex_joni> everything orange is moving parts
[19:26:37] <alex_joni> blue is static
[19:26:56] <cradek> huh
[19:28:33] <cradek> what controlled it initially?
[19:28:53] <alex_joni> it's still controlled by that
[19:28:55] <alex_joni> not emc :(
[19:29:52] <alex_joni> it's a control made by cloos
[19:30:08] <alex_joni> there are some pics with the cabinet there, iirc
[19:30:30] <cradek> yeah
[19:30:51] <alex_joni> it's basicly a 486 controller
[19:31:01] <alex_joni> and some custom FPGA's that do traj & interpolation
[19:39:57] <alex_joni> so, what are you up to?
[19:42:29] <cradek> oh me? just work right now
[19:42:41] <cradek> last night I used my new (to me) lathe to make a pulley for my milling machine's spindle
[19:42:48] <alex_joni> cool
[19:42:51] <alex_joni> got a lathe?
[19:43:03] <cradek> yeah a 6" atlas (WWII vintage I think)
[19:43:06] <alex_joni> * alex_joni finally has some hopes that emc might run a lathe someday
[19:44:39] <alex_joni> evening paul_c
[19:45:05] <cradek> alex_joni: it's very old and used, but I can make parts the right size with it, which is all that counts
[19:45:13] <paul_c> * paul_c grumbles about alex_joni's fiddling wih posemath.h
[19:45:16] <alex_joni> nice
[19:45:41] <cradek> * cradek grumbles about all of paul_c's #ifdef droppings
[19:46:06] <alex_joni> my fiddling?
[19:47:50] <alex_joni> can't recall touching posemath.h
[20:06:23] <alex_joni> http://www.patent2.de/end.htm
[20:35:28] <paul_c> right... That's the latest axis cvs snapshot patched to compile against emc2 AND BDI-4
[20:38:56] <jepler_> right now axis won't even compile against emc1 due to some gratuitous changes
[20:39:30] <jepler_> in fact I've been meaning to post a news article on the axis website about that, but I don't know how to keep it from coming out sounding bitter
[20:40:14] <paul_c> I would have prefered K.R. to mess things up in a branch...
[20:40:54] <paul_c> leave HEAD as stable with/for bug fixes only.
[20:41:16] <jepler_> perhaps it's as simple as teaching K.R. how to use branches with CVS?
[20:41:55] <paul_c> Post something to emc-dev list.
[20:43:40] <paul_c> that aside, Interested in this patch ?
[20:44:07] <jepler_> we'd love to have AXIS building against BDI-4
[20:44:24] <paul_c> OK, where do I send it ?
[20:44:31] <jepler_> jepler@unpythonic.net
[20:44:36] <jepler_> do you have it in patch format?
[20:45:03] <jepler_> if not, just tell me the snapshot you compiled it against and I can make the diff myself easily
[20:45:08] <paul_c> diff -uwr
[20:45:24] <jepler_> should do (I don't generally use -w)
[20:45:53] <paul_c> it just igores whitespace.
[20:46:20] <jepler_> if it works against the cradek_stable branch of emc1 I'll probably check it in after a quick review of the changes, otherwise I'll put the patch on the axis website download area
[20:47:07] <jepler_> what's with the n= and i= anyway?
[20:47:10] <paul_c> Just compiled against emc2 from today, and the BDI-4 sources I'm working with.
[20:47:47] <jepler_> similar enough to the latest released bdi?
[20:48:51] <jepler_> and does this mean that the next bdi 4.xx will have a new axis on it?
[20:49:02] <paul_c> Putting a new release together - There has been a merging of some more sources between emc2 HEAD & BDI-4 branch.
[20:51:22] <paul_c>
[21:00:43] <Jymmm> Hi Everybody!!!
[21:01:00] <Jymmm> (think Dr on the Simpsons)
[21:07:57] <jepler_> paul_c: ?
[21:11:04] <jepler_> paul_c: the patch applied and it still builds against CRADEK_STABLE. Maybe I should run it though...
[21:12:32] <paul_c> I hadn't got as far as running it... Still messing around building BDI-4 debs
[21:14:09] <jepler_> paul_c: well it runs against CRADEK_STABLE, so I checked it in. The next nightly CVS snapshot will have your patch
[21:19:01] <jepler_> paul_c: chris was just telling me about a change he made so that the "Zero Offset" button works properly...
[21:19:08] <jepler_> it is only in branch CRADEK_STABLE now
[21:19:56] <jepler_> it writes out the .var file whenever you change modes, and then the right offsets are used when you reload your file
[21:20:08] <jepler_> otherwise when using offsets you get the wrong display
[21:21:39] <paul_c> Will that be in tonght's snapshot ?
[21:23:20] <jepler_> no, it's a change to emc, not to axis
[21:23:21] <jepler_> http://cvs.sourceforge.net/viewcvs.py/emc/emc/src/rs274ngc_new/rs274ngc_pre.cc?r1=1.10&r2=
[21:24:14] <jepler_> "not a complex patch, and totally harmless (I think)" -- cradek
[21:25:35] <jepler_> http://cvs.sourceforge.net/viewcvs.py/emc/emc/src/rs274ngc_new/rs274ngc_pre.cc?r1=1.10&r2=
[21:27:24] <paul_c> OK.. That looks fairly trivial. I can merge that in without any ill effects.
[21:27:36] <jepler_> great
[21:36:30] <Jymmm> paul_c: Could you add in a beer brewing patch as well?
[21:37:49] <Jymmm> paul_c: once you get the beer patch goin, then we can work on the tequilia module !
[21:39:57] <paul_c> -ENOBOOZE
[21:40:10] <Jymmm> thats a good start!
[21:40:38] <Jymmm> les can test the -ENOMOONSHINE
[21:51:54] <LawrenceG> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7537278656&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1 nice looking mill
[21:53:18] <LawrenceG> they always seem to be on the otherside of the country.... looked into shipping one and it was about $1500usd
[22:27:00] <Jacky^> evening
