[00:04:55] <gezr> rotary axis are phasing out?
[00:05:08] <anonimasu> gezr: what?
[00:05:18] <gezr> just reading back up about what you said
[00:05:24] <gezr> oh and Howdy ya'll :)
[00:05:38] <anonimasu> gezr: yeah, I've found no use for my rotary table as I went with a cnc..
[00:06:03] <gezr> oh rotary table, I have a use for you that you may not have ever seen :)
[00:06:42] <gezr> machine axis as follows, Y(to and from you facing machine), Z (normal Z axis, up and down), C rotary table
[00:07:02] <anonimasu> gezr: new use`?
[00:07:03] <anonimasu> no
[00:07:11] <anonimasu> gezr: that's why I was wondering about a rotary axis..
[00:07:21] <gezr> have you ever seen a rtb machine?
[00:07:24] <anonimasu> RTB?
[00:07:39] <gezr> its a monarch design, sick fast
[00:07:42] <anonimasu> ah
[00:07:42] <anonimasu> no
[00:07:49] <gezr> mill square pockets and the works
[00:08:12] <anonimasu> yeah :)
[00:09:30] <anonimasu> gezr: I meant that you have less use for a rotary table when you have cnc..
[00:09:53] <anonimasu> unless you are doing 4 or 5 axis work :)
[00:10:06] <gezr> oh no, the need for one increased dramatically
[00:10:11] <gezr> think about it
[00:10:25] <gezr> im not talking about flat plane work, with the table facing up to Z
[00:10:39] <gezr> couldnt find the video link
[00:10:49] <anonimasu> I know what you mean..
[00:10:53] <anonimasu> |-WORKPIECE-|
[00:10:56] <anonimasu> like that :)
[00:10:59] <gezr> yeah
[00:11:01] <anonimasu> for making gears and such..
[00:11:10] <gezr> but then again, if your making a hole pattern
[00:11:23] <anonimasu> yeah
[00:11:33] <gezr> you have 2 axis drift versus, total error of one table
[00:12:04] <gezr> you see what im saying?
[00:12:29] <gezr> you can even with a fast enough servo on your table, you could turn with it
[00:13:32] <gezr> milling a bowl for example, instead of using a boaring bar, you could use a ball endmill, and just arc it in one axis, while the table rotates underneath
[00:14:17] <gezr> that would almost eleminate any out of roundness from say backlash
[00:14:57] <gezr> or am i just nuts?
[00:15:27] <Jymmm> either way, you are STILL nuts, but thats another story
[00:15:52] <gezr> HIT, you sank my battleship
[00:16:32] <Jymmm> oh man, I was aimign for the aircraft carrier!
[00:16:43] <gezr> hahaha
[00:17:14] <gezr> there are so many advantages to haveing a dividing head, or a rotary table, I can only dream about now
[00:19:01] <anonimasu> gezr: well, I've found less use for the rotary table since I got a cnc anyway..
[00:19:14] <anonimasu> the 0,001 deviance in roundness is something I can live with
[00:24:37] <anonimasu> night all
[00:38:54] <Jacky^> nigh anonimasu
[00:47:04] <Jacky^> * Jacky^ confused
[00:47:17] <Jacky^> i've too much linear tracks
[00:47:19] <Jacky^> :\
[00:47:24] <Jacky^> seen*
[00:48:28] <Jacky^> here there is to studying for years..
[00:48:39] <Jacky^> * Jacky^ sigh
[00:52:21] <Jacky^> Night
[00:54:00] <Jymmm> G'Night Jacky^
[00:54:19] <Jacky^> bye
[21:16:23] <alex_joni> you ruined it
[21:16:28] <alex_joni> with a bad driver
[21:16:29] <alex_joni> :D
[21:16:35] <anonimasu> yeah right..
[21:16:43] <alex_joni> :P
[21:17:04] <paul_c> From what I remember.... There should be a green LED that stays on when power is applied...
[21:17:14] <anonimasu> :(
[21:17:23] <paul_c> and a second when EMC runs
[21:17:32] <anonimasu> no that's the estop OK
[21:17:55] <alex_joni> yeah.. the most fun things in electronics projects
[21:18:04] <alex_joni> make the LED light
[21:18:04] <alex_joni> :D
[21:18:13] <alex_joni> after that it's easy
[21:18:32] <paul_c> suggestion: Check the +5V rail on the USC
[21:19:59] <anonimasu> resolution: +5v on the rail
[21:23:20] <paul_c> 'k... For a minute I thought the PSU might be going in to current overload...
[21:23:55] <paul_c> Is the parallel port set for bi-directional data in the BIOS ?
[21:24:08] <anonimasu> I dont know
[21:24:12] <anonimasu> want me to check it?
[21:26:26] <paul_c> Please.
[21:26:44] <alex_joni> hmm.. thought you were just having smalltalk :D
[21:26:52] <paul_c> alex_joni: You got emc2 compiled yet ?
[21:27:04] <alex_joni> got the kernel source ;)
[21:27:25] <alex_joni> getting rtai-dev now
[21:28:25] <alex_joni> err.. didn't get kernel-source
[21:28:26] <alex_joni> :(
[21:28:34] <alex_joni> it's not on the ntworld repo
[21:29:36] <anonimasu> dosent work
[21:29:44] <anonimasu> I set the port as ECP
[21:29:59] <anonimasu> or should I have set it as ECP/EPP
[21:30:11] <paul_c> try ECP/EPP
[21:30:16] <anonimasu> ok
[21:30:17] <anonimasu> sec
[21:35:17] <anonimasu> no
[21:35:19] <anonimasu> dosent work
[21:35:33] <anonimasu> although now the load fail lights up when I pull the power out of the card
[21:36:36] <paul_c> silly question: Are you using a good quality parport cable suitable for bi-directional use ?
[21:36:43] <anonimasu> yes
[21:36:50] <anonimasu> I've got 2
[21:36:51] <paul_c> OK.
[21:37:45] <paul_c> About the only recourse is to email Jon Elson and demand he joins you on IRC to debug the problem.
[21:38:12] <paul_c> * paul_c has reached the limit of knowledge with ppmc hardware.
[21:39:08] <anonimasu> :/
[21:40:02] <paul_c> I've only ever connected to a USC board once, and that was just to prove that BDI-4.2x worked with it..
[21:40:05] <anonimasu> yeah I'll drop him a mail..
[21:40:50] <paul_c> tell Jon about the missing FIND_IO_BASE_ADDRESS symbol & the required fix.
[21:42:05] <anonimasu> hm, ./univstepdiags bus
[21:42:10] <anonimasu> should show the board..
[21:42:44] <anonimasu> I wonder if it's just the port.
[21:43:25] <paul_c> it might be...
[21:43:45] <anonimasu> since it's been used & abused..
[21:43:52] <anonimasu> but ll drop him a mail about it
[21:44:01] <anonimasu> there's probably some way to verify if it's the USC..
[21:44:10] <anonimasu> I think it's strange that the other stuff on it lights up
[21:44:18] <Jymmm> There is a utility on his website to do that
[21:44:29] <paul_c> I'm pretty certain at least one LED should remain on when the USC is powered up.
[21:44:36] <anonimasu> paul_c: I am not..
[21:44:44] <anonimasu> it's the estop led and the power fail led.
[21:44:51] <anonimasu> the estop lights up when you close the estop chain
[21:44:56] <Jymmm> anonimasu " Download Linux diagnostic program for Universal Stepper Controller."
[21:45:03] <anonimasu> * anonimasu slaps Jymmm
[21:45:11] <Jymmm> anonimasu what?
[21:45:19] <anonimasu> Jymmm: it shows nothing.
[21:45:21] <anonimasu> http://www.pico-systems.com/codes/univstepdiag.html
[21:45:27] <paul_c> * paul_c hands anonimasu a large brick.
[21:45:36] <anonimasu> * anonimasu smacks Jymmm once from paul
[21:45:38] <Jymmm> anonimasu you root?
[21:45:52] <alex_joni> * alex_joni hands anonimasu another brick
[21:46:10] <paul_c> Jymmm: I think they are ganging up on you..
[21:46:37] <Jymmm> paul_c: I have some mortar ready.... gonna encase them in theri own bricks
[21:46:41] <alex_joni> u think?
[21:46:42] <anonimasu> Jymmm: I think so
[21:46:42] <anonimasu> :D
[21:46:59] <anonimasu> * anonimasu wonders if it's just the port once again
[21:48:18] <Jymmm> anonimasu did you email jon yet?
[21:48:53] <paul_c> Jymmm: <pedant mode=on> "Have you emailed..."
[21:49:18] <Jymmm> paul_c: /kick yourself then take it to #engwish
[21:49:33] <paul_c> pfft
[21:49:57] <paul_c> * paul_c is bilingual
[21:50:18] <Jymmm> paul_c is bi? TMI
[21:50:53] <paul_c> fluent in both English and 'mericun
[21:51:13] <Jymmm> Have any of you tried using SVG for machining by chance?
[21:55:13] <anonimasu> no, not yet
[21:55:17] <anonimasu> I am still in the shop.
[21:55:36] <anonimasu> I have not emailed Jon yet.
[22:06:12] <paul_c> http://www.cnczone.com/forums/archive/index.php/t-10901.html - Hrmmm....
[22:14:12] <Jymmm> Fuck.... most of the response to that are ..... gimme it free fucker!
[22:14:26] <CIA-3> 03jmkasunich * 10emc2/src/rtapi/mathstubs.c: isnan and __isnan need to be treated independently, at lease on some systems
[22:19:54] <les> oh boy.
[22:20:17] <les> Got a call requesting more acoustics consulting.
[22:20:48] <les> Why couldn't it have been like this a couple years ago?
[22:21:00] <les> bleh
[22:29:03] <alex_joni> * alex_joni will be back later
[22:29:06] <alex_joni> maybe ;)
[22:29:16] <les> gee hope so.
[22:30:44] <alex_joni> heh
[22:31:43] <Jymmm> thanks paul_c
[22:33:55] <Jacky^> hey guys
[22:34:14] <Jacky^> some mounth ago i bought a small motor: http://www.micromed.it/Elettronica/images/mot%20enc%20dig.jpg
[22:34:36] <Jacky^> is there a way to run it without complex circuits ?
[22:34:49] <Jacky^> just for testing
[22:35:48] <Jacky^> it should have internal encoder
[22:37:24] <anonimasu> hm
[22:38:15] <Jacky^> 4 leads on motors
[22:38:27] <Jacky^> motor*
[22:43:48] <Jacky^> the motor looks as an alien
[22:44:52] <anonimasu> I just dropped the mail to jon
[22:50:13] <paul_c> * paul_c gets the rcslib java apps running via http
[22:56:42] <Jacky^> anonimasu: maybe I found: http://www.vincenzov.net/progetti/dualmos.htm
[22:57:03] <anonimasu> yeah
[22:57:21] <Jacky^> oh.. no..
[22:57:22] <anonimasu> night all
[22:57:26] <Jacky^> night anonimasu
[22:58:34] <Jymmm> Jacky^ DC brushed motor, runs on 24,36,42 volts
[22:59:19] <Jymmm> Jacky^ : I have the sales engineer on the phone
[22:59:40] <Jymmm> that 02.1979 is the date code.... Feb 1979
[23:00:08] <Jymmm> the long number is the P/N but they had changed to a new PN scheme
[23:01:17] <Jacky^> oh..
[23:01:58] <Jymmm> He's going to fax me over the datasheet this afternoon, but it's in German.
[23:02:01] <Jacky^> I (maybe) really found now: http://www.vincenzov.net/progetti/motoredc.htm
[23:02:34] <Jacky^> Jymmm: i already have this DC motor
[23:02:47] <Jacky^> i want to try it just for fun ..
[23:02:52] <Jymmm> I thought yo usaid you bought this morot? ----> http://www.micromed.it/Elettronica/images/mot%20enc%20dig.jpg
[23:02:55] <Jacky^> it's a toy :)
[23:03:16] <Jacky^> Jymmm: yeah
[23:03:41] <Jacky^> E. 5
[23:03:43] <Jymmm> Jacky^ Ok, that is the mfg I just got off the phone with. They make precision motors
[23:04:13] <Jacky^> ah.. nice
[23:04:26] <Jymmm> Jacky^ it runs off of runs on 24,36,42 volts
[23:04:26] <Jymmm> [15:01:10] <Jymmm> Jacky^ : I have the sales engineer on the phone
[23:04:40] <Jymmm> Jacky^ it runs off of 24,36,42 volts
[23:04:57] <Jymmm> so, you only need to wires
[23:05:05] <Jymmm> GND and v+
[23:05:15] <Jacky^> understood
[23:05:17] <Jymmm> ok
[23:05:24] <Jacky^> but there are 4 leads
[23:05:41] <Jacky^> 2 of these should be incremental encoder
[23:05:42] <Jymmm> Right, one for 24V, another for 36V and a third for 42V
[23:05:55] <Jymmm> plus ground
[23:06:04] <Jymmm> it is NOT a stepper or servo.
[23:06:21] <Jacky^> ahh..
[23:06:30] <Jymmm> Let him fax over the datasheet in a couple hours
[23:06:31] <Jacky^> i was thinking it was like a servos
[23:06:40] <Jymmm> no, it's a PURE DC motor
[23:06:43] <Jacky^> ok..
[23:06:52] <Jacky^> now is clear
[23:06:56] <anonimasu> dosent matter
[23:06:56] <Jymmm> but like I said, it's in German
[23:07:11] <anonimasu> the only diff betwee a normal dc motor and brushed servo are the rotor inertia..
[23:07:12] <Jymmm> and I don't read/speak German
[23:07:18] <anonimasu> servos are slightly more optiimzed..
[23:07:23] <anonimasu> optimized..
[23:07:33] <anonimasu> but with a encoder you can use a normal DC motor as a servo..
[23:07:54] <Jacky^> anonimasu: it should have internal incremental fotoencoder
[23:08:06] <anonimasu> Jacky^: does it?
[23:08:09] <anonimasu> or should it?
[23:08:16] <Jacky^> i suppose on 2 pin, could be possible to read some voltage value
[23:08:23] <anonimasu> you need a encoder.
[23:08:26] <Jacky^> does i think
[23:08:37] <anonimasu> real encoders to use a normal DC motor as servo.
[23:08:42] <Jacky^> Motore con encoder fotoelettrico incrementale 12V
[23:08:59] <anonimasu> well too small to be usable in the real works
[23:09:01] <anonimasu> world..
[23:09:02] <Jacky^> Motor with photoeletric encoder
[23:09:08] <anonimasu> ;)
[23:09:09] <anonimasu> night
[23:09:15] <Jacky^> night
[23:09:32] <Jacky^> i know it's small
[23:09:56] <Jacky^> i just want to learn an try..
[23:10:07] <Jacky^> * Jacky^ take the hammer
[23:10:16] <Jacky^> fight now !
[23:10:25] <Jacky^> damn motor
[23:10:28] <Jacky^> :D
[23:12:19] <Jacky^> Jymmm: that ok
[23:12:33] <Jacky^> on the bottom there are other 2 leads
[23:13:05] <Jacky^> with a capacitor of 100 ns connected
[23:13:15] <Jacky^> ns ?
[23:13:24] <Jacky^> maybe is not a capacitor..
[23:13:51] <Jacky^> anyway this will be encoder output
[23:15:03] <Jacky^> Jymmm: thanks
[23:17:08] <Jymmm> Jacky^ you better learn german within an hour
[23:17:42] <Jacky^> hehe.. sorry ..
[23:17:59] <Jacky^> i need to translate before reply :s
[23:19:06] <Jacky^> swiss made..
[23:19:26] <Jacky^> when maxon is in USA right ?
[23:24:20] <Jacky^> this motor was probably used in some precision application years ago
[23:25:40] <Jymmm> Ths office in USA, is 40 minutes from me =)
[23:25:54] <Jacky^> cool
[23:26:20] <Jacky^> maxon seem to me have great products
[23:30:22] <Jymmm> Jacky^ : No Idea, just trying to get you the info you needed is all =)
[23:30:32] <Jymmm> hi LawrenceG
[23:30:36] <Jacky^_> Jymmm: thanks a lot ;)
[23:31:29] <Jymmm> Jacky^_ : Just remember... If I ever get to Italy, you have to provide a nice Italian gal, about 20 something and MUTE =)
[23:31:51] <Jacky^> hehe
[23:31:55] <Jacky^> sue :))
[23:31:58] <Jacky^> sure*
[23:32:02] <Jymmm> liar!
[23:32:34] <paul_c> Jymmm: The Italians don't know what a gallon is...
[23:32:50] <Jymmm> paul_c vino
[23:32:53] <paul_c> Jacky^: A US gallon is 3.95l
[23:32:54] <Jacky^> I've an idea..
[23:33:04] <Jacky^> :)
[23:33:20] <Jymmm> gal, chick, woman, girl, female of the species
[23:33:24] <paul_c> and an Imperial gallon is 4.5461l
[23:33:26] <Jacky^> lol
[23:33:29] <Jacky^> understood
[23:33:53] <Jacky^> we have, np :))
[23:35:50] <Jymmm> Jacky^ but remember she HAS to be MUTE, I can't handle all the screaming, hiting and biting are ok though =)
[23:36:04] <Jymmm> s/screaming,/screaming./
[23:36:09] <Jacky^> Jymmm: i will do all possible
[23:36:13] <Jacky^> :D
[23:36:15] <Jymmm> liar
[23:36:17] <Jymmm> lol
[23:36:25] <paul_c> Jymmm: Earplugs ?
[23:36:34] <LawrenceG> hey Paul... what is the price of petrol in your end of the world.... its Cdn$1.06/l here
[23:36:50] <Jymmm> paul_c earplugs for an Italian woman?! I don't think so
[23:36:55] <paul_c> nearly �1.00 per litre
[23:37:08] <Jymmm> $3USD/gal for premium
[23:37:08] <Jacky^> here the girls love a fun
[23:37:19] <Jacky^> and sometime, credit card :\
[23:37:19] <paul_c> * paul_c slaps Jymmm
[23:37:23] <Jacky^> but depend..
[23:37:27] <Jacky^> :P
[23:37:32] <Jymmm> paul_c: for which ?
[23:37:43] <paul_c> $3USD
[23:37:54] <Jymmm> paul_c: That was as of yesterday
[23:38:08] <Jymmm> well 2.99 and 9/10
[23:38:21] <paul_c> wait till it hits $5
[23:38:33] <LawrenceG> time to get a moped
[23:38:40] <LawrenceG> diesel
[23:39:04] <paul_c> a diesel moped ?
[23:39:12] <Jymmm> BioDiesel maybe
[23:39:52] <Jacky^> gpl
[23:39:59] <Jacky^> free ..
[23:40:01] <Jacky^> :)
[23:40:53] <Jacky^> here gpl cars can move on weekend
[23:41:03] <Jacky^> in the bid metropoly
[23:41:11] <Jacky^> big*, others not
[23:41:37] <paul_c> http://journeytoforever.org/biodiesel_bikes.html
[23:43:16] <Jacky^> paul_c: nice :) i like this: http://journeytoforever.org/media/h/hatz2.jpg
[23:44:16] <Jacky^> first time i eard of diesel bikes
[23:44:50] <Jacky^> usually who buy a bike love a speed..
[23:44:52] <paul_c> hell... Diesel Harley....
[23:45:09] <Jacky^> i've seen, nice
[23:45:40] <les> I have been buying diesel for the first time for my new tractor.
[23:46:10] <les> If the oil goes away I will just grow diesel fuel!
[23:46:13] <Jacky^> here the prices in order to maintain the disel are many high ones
[23:46:30] <LawrenceG> I love diesel.... have a 1 ton dodge pickup and a VW bug in diesel
[23:46:39] <Jacky^> there's a fixed tax for a year
[23:47:31] <LawrenceG> the bug gets about 3 times better mileage!
[23:47:59] <les> Well diesel has more specific energy, and the high compression gives much higher carnot efficiency
[23:48:28] <LawrenceG> I like the idea of having oil on both sides of the piston
[23:48:35] <les> heh
[23:48:58] <Jacky^> LawrenceG: why ?
[23:49:09] <Jacky^> for the long life of motor ?
[23:49:34] <LawrenceG> always wondered how a gas engined survived... piston goes up... cylinder gets oiled... piston goes down, the gas washes off all the lubrication
[23:51:25] <LawrenceG> http://www.amproexports.com/lister-diesel-engines.html ... I would like one of these for a generator
[23:51:47] <les> I think the reason is that the majority of petroleum fractions are of gasoline molecular weight
[23:51:55] <les> perhaps
[23:52:41] <Jacky^> my cousin have a big generator.. 4x4 mt
[23:53:22] <LawrenceG> maybe a new retrofit.... diesel bridgeport
[23:53:29] <les> haha
[23:53:32] <LawrenceG> with emc
[23:54:02] <Phydbleep> LawrenceG: Running on a Babbage Numerator?
[23:59:16] <LawrenceG> http://www.utterpower.com/listeroi.htm this guy imports them... lots of interesting reading... kind of heavy for a moped
