[00:25:36] <crepincdotcom> i need a wicked quick bipolar driver.... i have a bunch of L297 and L298 lying around, but I'm yet to make the two work together
[00:25:54] <crepincdotcom> anyone have a simple way to set them up? I don't need the chopper or current sensing
[00:27:48] <jmkasunich> stepper?
[00:28:02] <crepincdotcom> yeah
[00:28:03] <jmkasunich> how are you going to limit the current? use low voltage?
[00:28:14] <crepincdotcom> s/low/proper
[00:28:21] <crepincdotcom> that part of the driver isnt usually used anyway
[00:28:27] <jmkasunich> s/proper/low and slow/
[00:28:29] <crepincdotcom> its just picky about it being there
[00:28:34] <alex_joni> crepincdotcom: proper voltage for a stepper is 20-30 times the rating
[00:28:37] <alex_joni> but limiting the current
[00:28:53] <crepincdotcom> uhhhh how do you propose one does that
[00:28:57] <jmkasunich> you can do a low voltage driver, where the coil R limits the current
[00:29:06] <jmkasunich> but you'll have limited max step rate
[00:29:09] <crepincdotcom> right, thats what i have now
[00:29:14] <crepincdotcom> with unipolar motors
[00:29:15] <alex_joni> crepincdotcom: I'd use the pminmo schematic
[00:29:23] <crepincdotcom> but i have Bipolar motors that are larger
[00:29:27] <jmkasunich> modern drivers use choppers, so the applied voltage is high, then when the current gets to where it should be they start chopping
[00:29:42] <crepincdotcom> ug.
[00:29:49] <jmkasunich> what are the motor ratings? (amps, volts, etc)
[00:29:48] <alex_joni> http://www.pminmo.com/l297-8/l297-8.htm
[00:29:52] <crepincdotcom> that involves way too much setting up
[00:30:01] <Skullworks> http://engraving.majosoft.com/html/stepper_driver_board_with_l297_and_L6203.html
[00:30:13] <crepincdotcom> jmkasunich: i have a buncha different motors, i just want a generic bipolar driver that i can test them with
[00:30:16] <jmkasunich> good, fast, cheap, pick 2
[00:30:17] <alex_joni> crepincdotcom: I also suggest reading this: http://www.geckodrive.com/photos/Step_motor_basics.pdf
[00:30:27] <crepincdotcom> hm
[00:30:29] <alex_joni> jmkasunich: gecko :D
[00:30:37] <fenn> gecko aint cheap
[00:30:45] <jmkasunich> yes - read that gecko paper, then you'll probably know the answers
[00:31:01] <jmkasunich> no, they ain't, but the paper is good regardless of whether you buy geckos or not
[00:31:02] <alex_joni> fenn: he only said 2 :D
[00:31:09] <fenn> heh ok
[00:31:20] <jmkasunich> first law of engineering: good fast cheap, pick 2
[00:31:30] <fenn> thought that was murphy's law, but oh well
[00:31:38] <jmkasunich> geckos are good and fast (fast in this case means design time - or purchase time actually)
[00:31:59] <alex_joni> no, murphy's law will tell that if you're building it it won't be neither good, nor fast nor cheap
[00:32:04] <alex_joni> at least not the first 5 times
[00:32:16] <jmkasunich> homebrew can be fast and cheap, but bad (unipolar, or bipolar L/R) or good and cheap (choppers, but you'll spend weeks getting everything right)
[00:32:24] <fenn> where 5 is actually n+1
[00:32:39] <alex_joni> probably :D (or n!)
[00:33:07] <robin_sz> to be fair ... the geckos are good, fast and (relatively) cheap
[00:33:27] <jmkasunich> cheap is relative - for their performance they are cheap
[00:33:31] <fenn> and steppers suck btw
[00:33:34] <robin_sz> * robin_sz nods
[00:33:37] <crepincdotcom> yeah anything id use i'd build
[00:33:46] <jmkasunich> for a hobbyist on a budget, they are a big hole in the wallet
[00:33:50] <crepincdotcom> steppers suck, what are you PWMing DC motors?
[00:33:51] <crepincdotcom> that sounds lame
[00:33:59] <fenn> ever heard of an optical encoder?
[00:34:09] <crepincdotcom> point being
[00:34:14] <fenn> its better than a stepper
[00:34:23] <crepincdotcom> its MORE ACCURATE: != better neccesarily
[00:34:24] <robin_sz> better is a loose term
[00:34:33] <fenn> it's better because i say so :P
[00:34:49] <robin_sz> for some apps steppers are better, for some apps servos are better ...
[00:34:52] <robin_sz> it depends
[00:35:40] <fenn> crepincdotcom: dont come bitching to me when you lose a step and your part is scrapped
[00:35:53] <crepincdotcom> ...i wasnt bitching
[00:35:52] <skunkworks> after playing a bit with a cheap servo drive and encoders.. I really like dc servos. They have lost thier spookyness.
[00:36:02] <crepincdotcom> steppers are simply easier to setup and run
[00:36:22] <robin_sz> and, if done right are perfectly adequate
[00:36:25] <robin_sz> for some apps
[00:36:25] <alex_joni> * alex_joni sticks with his AC servos at work
[00:36:39] <robin_sz> well yeah, dont we all :)
[00:37:28] <fenn> matt shaver was working on a modbus ac servo drive
[00:37:35] <fenn> wonder if that ever went anywhere
[00:38:00] <robin_sz> lots and lots of current spec "sign" routers, the 1m x 1m sorta size for acryllic etc ... lots of the commercial ones are stepper driven and generally they dont give problems ... it all depends on design and application
[00:38:00] <fenn> trying to get it to work with emc i mean
[00:38:01] <alex_joni> well, if he got it to work..
[00:40:53] <jmkasunich> figured out my lost steps (finally)
[00:41:10] <alex_joni> oh, you found those?
[00:41:28] <jmkasunich> yeah, its an analog issue
[00:41:33] <alex_joni> * alex_joni heads to bed :)
[00:41:37] <alex_joni> good night all
[00:41:44] <jmkasunich> I knew the 3.3V output from the fpga was marginal
[00:41:54] <jmkasunich> since the gecko optos have a 5V source
[00:42:08] <jmkasunich> even when high, there is a chance for a bit of current thru the led
[00:42:21] <jmkasunich> enough to greatly lengthen the rise time
[00:42:26] <robin_sz> yeah
[00:42:47] <robin_sz> nice little open collector output would be better
[00:42:50] <jmkasunich> result - if the high time (led off) is less than about 30uS, the step gets missed
[00:43:05] <jmkasunich> yeah, thats what I'll be doing for the final version
[00:43:17] <robin_sz> there are some nice chips to do that
[00:43:26] <robin_sz> fpga->real world
[00:43:36] <jmkasunich> open collector, or HCT logic that is happy with 3.3V input swing, and goes rail to rail on the output
[00:43:37] <robin_sz> ISTR Mariss uses some on the GREX
[00:44:08] <jmkasunich> I miss 5V LSI
[00:44:32] <robin_sz> he had some nice 3.3V to dfet output things .. took 100ma or more on the output side if I remember right
[00:45:07] <robin_sz> the 3.3v stuff is umm ... well
[00:45:16] <robin_sz> high is what anything over 2.2
[00:45:23] <robin_sz> low is anything blow 1.5?
[00:45:34] <robin_sz> ISTR it was a bit "vague"
[00:45:44] <jmkasunich> bah
[00:45:58] <jmkasunich> gimme 5V logic and +/- 10V analogs, with +/-15 supplies
[00:46:04] <jmkasunich> old school ;-)
[00:46:13] <robin_sz> yeah
[00:46:39] <robin_sz> 3.3v logic is ok on chip and intra-chip .. but you dont want it going off the board really
[00:46:44] <robin_sz> too feeble
[00:46:46] <jmkasunich> right
[00:47:05] <jmkasunich> and in a noisy environment, its too feeble on the board too
[00:47:08] <robin_sz> is this your first set of geckos then?
[00:47:11] <jmkasunich> yes
[00:47:21] <robin_sz> pleased?
[00:47:26] <jmkasunich> had them for over a year, only started messing when them lately
[00:47:38] <jmkasunich> getting more pleased as I find out the issues
[00:47:44] <robin_sz> right
[00:47:47] <alex_joni> robin_sz: try working with .9V VCC :)
[00:47:54] <alex_joni> that's for intra-chip these days
[00:48:00] <robin_sz> they pack a lot of punch for a tiny box
[00:48:02] <jmkasunich> I ran them at 2400 RPM using a signal generator couple days ago
[00:48:08] <robin_sz> heh
[00:48:24] <jmkasunich> they'd do 3000 if you didn't ask for too much accel/decel
[00:48:42] <robin_sz> nice
[00:49:16] <jmkasunich> 990 oz-in
[00:49:35] <robin_sz> good size motors
[00:50:14] <Skullworks> at what voltage?
[00:50:20] <jmkasunich> 55ish
[00:51:02] <Skullworks> thats geckos other strong point - they are one of very few that go over 50V
[00:51:06] <jmkasunich> which by a coincidence is the temp in degrees C they reach after running for a while
[00:51:29] <jmkasunich> robin_sz: they're only 100mm long, not counting the back end shaft
[00:51:40] <jmkasunich> (or the front shaft)
[00:51:54] <Skullworks> 34's ?
[00:52:03] <jmkasunich> yep
[00:52:03] <robin_sz> coo
[00:52:10] <robin_sz> nice
[00:52:17] <robin_sz> Sanyos?
[00:52:18] <jmkasunich> 2.1V 6.1A, 3.3mH 0.35ohm
[00:52:21] <jmkasunich> chinese
[00:52:29] <jmkasunich> keling
[00:52:34] <robin_sz> cheap?
[00:52:40] <Skullworks> 3.3mH - thats sweet
[00:52:39] <jmkasunich> $109
[00:52:48] <robin_sz> coo
[00:52:50] <robin_sz> cheap
[00:53:02] <jmkasunich> I picked the lowest voltage and inductance in the 700-1200 oz-in class
[00:53:08] <robin_sz> good call
[00:53:16] <alex_joni> good night all
[00:53:21] <robin_sz> night alex_joni
[00:53:26] <jmkasunich> night alex
[00:53:34] <Skullworks> nity
[00:53:39] <robin_sz> feed em smooth pulses and gear em right, they shoudl fly
[00:53:51] <Skullworks> gear?
[00:54:09] <robin_sz> gear as in match them to the load
[00:54:41] <jmkasunich> http://www.kelinginc.net/SMotorstock.html, first one listed under 3:
[00:54:48] <jmkasunich> they call em 906 oz-in now
[00:55:09] <jmkasunich> re: gearing - the machine was built with 2:1 reduction to the screws
[00:55:19] <jmkasunich> and 10 tpi acme screws
[00:55:36] <Skullworks> I have 3 of ther 280oz-in and there 450~ both 23's
[00:55:40] <jmkasunich> I'd eventually like to switch to ballscrews, which will be 5tpi most likely
[00:55:44] <Skullworks> nice company
[00:56:11] <Jymmmm> jmkasunich get the preloaded ones with brushes =)
[00:57:17] <Jymmmm> well, shit... I guess I'm going to buy the 6 -0rt raid card instead of the NAS box
[00:58:02] <jmkasunich> hmm... up to about 60C now
[00:58:22] <Jymmmm> I'm in shorts and a t-shirt =)
[00:58:33] <SWPadnos> ewwwww
[00:58:38] <Guest482> I'm stark bollock naked...
[00:58:44] <Guest482> Actually I am not...
[00:58:46] <SWPadnos> ewwwww
[00:58:51] <Guest482> It's too cold here... Ireland...
[00:59:05] <robin_sz> ireland?
[00:59:06] <SWPadnos> aye - you're probably almost as cold as here
[00:59:13] <SWPadnos> then again, probably not
[00:59:15] <Guest482> So, is the deal here that everyone is using LinuxCNC?
[00:59:25] <SWPadnos> EMC2, but close enough
[00:59:34] <Jymmmm> TurboCNC FTW!
[00:59:36] <fenn> actually a lot of people just hang around and talk a lot of shit
[00:59:38] <SWPadnos> LinuxCNC is just the website name
[00:59:40] <Guest482> Ireland is colder than everywhere but the Nordics & Russia...
[00:59:45] <Guest482> & Canada...
[00:59:50] <SWPadnos> and Vermont
[00:59:53] <Guest482> I give you Canada...
[00:59:56] <Jymmmm> or should I say FTMS-DOS =)
[00:59:58] <jmkasunich> and ohio
[01:00:01] <Guest482> Okay... shades of Monty Python here...
[01:00:02] <robin_sz> jmkasunich, so 1 turn = 1/20th of an inch?
[01:00:09] <jmkasunich> yeah
[01:00:15] <SWPadnos> what is this, the Spanish Inquisition?
[01:00:36] <Skullworks> sure - English edition
[01:00:46] <Jymmmm> SWPadnos: Of course not, we're saying that till you hit California
[01:00:49] <robin_sz> you do reallise that sketch is probably 30 years old now?
[01:00:59] <Jymmmm> sa/saying/saving/
[01:01:00] <SWPadnos> yep :)
[01:01:02] <jmkasunich> robin_sz: so 1500 RPM (should have heaps of torque there) will give me 75ipm
[01:01:03] <Guest482> Yes... over...
[01:01:08] <jmkasunich> plenty for this class of machine
[01:01:11] <SWPadnos> closer to 40, I think
[01:01:30] <robin_sz> jmkasunich, yep ... sounds good.
[01:01:34] <Guest482> So... anyone made a minature lathe here?
[01:01:53] <Skullworks> keep in mind the stepper torque will have dropped off alot at 1500rpm
[01:01:53] <fenn> i made a 6" dia swing 18 or so between centers
[01:01:53] <Guest482> (I think I snuck that question in there nicely)
[01:02:43] <Guest482> A big shoebox lathe
[01:02:48] <Guest482> Mmmm...
[01:02:49] <jmkasunich> no...
[01:02:59] <fenn> Guest482: http://fenn.freeshell.org/lathe_pedestal.jpg
[01:03:38] <Jymmmm> * Jymmmm can confirm that's fenn workshop.... It's so freaking dark you can develope color film in there!
[01:03:40] <jmkasunich> Guest482: what size lathe do you have to use to make your lathe?
[01:03:59] <fenn> a shaper is really the best tool to make lathes with
[01:04:11] <Jymmmm> fenn a what?!
[01:04:12] <jmkasunich> kinda hard to make a spindle with a shaper
[01:04:19] <Guest482> I guess I'd use a standard one.. from a Uni...
[01:04:20] <fenn> or a grinder maybe
[01:04:26] <robin_sz> jmkasunich, so, say 400 oz-in at 1500 rpm ... the effective gearign is 6.128/ 0.05 =~ 125 ... 125 x 400 = 50,000 oz of thrust ... say 70% of that due to the efficiency of ths scme screw ... 35,000 oz of thrust ...
[01:04:34] <jmkasunich> Jymmmm: a shaper - not a wood shaper (upside down router) a metal shaper
[01:04:53] <Jymmmm> jmkasunich never heard of one before.
[01:04:56] <jmkasunich> efficiency is probalby more like 15%
[01:05:04] <robin_sz> could be
[01:05:19] <robin_sz> pour more oil on it
[01:05:47] <Skullworks> shaper - thats old school even by my standards
[01:05:46] <jmkasunich> Jymmmm: http://www.kelinginc.net/SMotorstock.html
[01:06:22] <jmkasunich> http://www.geocities.com/euxineseaweed/shaper.html
[01:06:24] <fenn> Guest482: are you planning on building a lathe?
[01:06:28] <jmkasunich> oops, wrong link the first time
[01:07:36] <Jymmmm> jmkasunich Not really =) Kinda like the dual shaft 1200 in/oz 4wire stepper =)
[01:07:43] <Jymmmm> 6a, just not sure on the voltage
[01:07:52] <jmkasunich> go for the 906 oz-in ones
[01:07:56] <robin_sz> ahh ...
[01:07:59] <jmkasunich> lower inductance, better top speed
[01:08:01] <Jymmmm> * Jymmmm pulls out the ohms law doohickey
[01:08:05] <robin_sz> now, the bottom picture on that site ...
[01:08:13] <jmkasunich> probably have just as much torque at high speed as the 1200's
[01:08:15] <robin_sz> THATS a real shaper!!!
[01:08:39] <jmkasunich> no its not, its a planer
[01:08:50] <Jymmmm> so about 75v @ 6a for this ---> KL34H2120-60-4B(Dual shaft with flat) Specification Price: $129 ( in stock)
[01:09:18] <Guest482> Fenn... okay... this is the story... I'm a MechEng grad' ('bout seven years ago, so rusty)
[01:09:34] <jmkasunich> rusty?
[01:09:35] <fenn> that's ok half of what you learned in school will be irrelevant
[01:09:56] <Guest482> I was good @ exams but not that that counts for crap...
[01:09:59] <jmkasunich> seven years is just about perfect - you forget all the crap they teach you in school and learn the real world stuff
[01:10:08] <Guest482> I've been Computing & Mathsing since...
[01:10:14] <jmkasunich> ohhh
[01:10:15] <Jymmmm> * Jymmmm lol @ jmkasunich
[01:10:22] <robin_sz> Jymmmm, forget about ohms law, the inductance is more important
[01:11:01] <Jymmmm> ok, 6mH
[01:11:09] <Guest482> Now.. I was looking @ RepRap... & thinking about MEMS... & the idea of making a mini-lathe (possibly shoebox size) came up...
[01:11:15] <jmkasunich> the 906 oz-in ones are only 3.3mH
[01:11:33] <Guest482> (is 'computing & mathsing' bad? :|?)
[01:11:43] <fenn> Guest482: make sure your spindle has a decent through-bore (at least 1/2")
[01:11:54] <jmkasunich> no, it just means you weren't excersizing your mechE muscles
[01:12:01] <Skullworks> 6mH is bordlineline
[01:12:15] <robin_sz> low inductance = high torque at high speed
[01:12:27] <Jymmmm> oh shit... just noticed the shaft is 1/2", not 1/4"
[01:12:38] <jmkasunich> 1/4"? thats nutz
[01:12:49] <jmkasunich> standard for NEMA34 is 3/8
[01:12:50] <Jymmmm> jmkasunich for *MY* machine
[01:12:53] <Guest482> looking up spindle & through-bore.. (excuse me & forgive my ignorance)
[01:12:55] <jmkasunich> but the high torque ones use 1/2
[01:13:02] <Jymmmm> jmkasunich these are NEMA23
[01:13:12] <jmkasunich> if you have 1/4" shafts, you just plain don't need 1200 oz-in
[01:13:15] <Jymmmm> Item #10
[01:13:45] <fenn> Guest482: spindle is the part that turns; usually there's a hole through it so you dont have to cut your round stock off and waste a part of it
[01:14:02] <fenn> also you can use collets which are more rigid and accurate than a chuck
[01:14:36] <jmkasunich> Jymmmm: pick the lowest inductance motor in the general torque range you are looking for
[01:15:06] <Guest482> I gotcha... fenn...
[01:15:15] <Jymmmm> I forget, if I buy a 8wire, I can still use it in 4wire configuration, correct?
[01:15:18] <fenn> wikipedia has a nice diagram naming all the lathe parts
[01:15:21] <jmkasunich> yes
[01:15:24] <Jymmmm> k
[01:15:37] <Jymmmm> geckos support the full 8wire config?
[01:15:52] <Guest482> thanks, it's probably better than what I'm using right now...
[01:15:57] <jmkasunich> no, you can connect an 8 wire motor in either series or parallel
[01:16:04] <jmkasunich> either way, when you are done there are four wires
[01:16:11] <Jymmmm> ah, cool
[01:16:12] <fenn> http://en.wikipedia.org/wiki/Lathe_(metal)
[01:16:19] <jmkasunich> Jymmmm: you don
[01:16:23] <fenn> parentheses mess up the URL sometimes
[01:16:26] <jmkasunich> you don't wnat #10
[01:16:31] <skunkworks> fenn: did you cast the spindle on your lathe?
[01:16:32] <jmkasunich> want even
[01:16:39] <Jymmmm> I'm hoping I dont' have to replace anything, but I'm keeping my eye out
[01:16:39] <Skullworks> * wire gives you all the options
[01:16:42] <fenn> skunkworks: no, it's a piece of scrapyardonium
[01:16:45] <Skullworks> 8 wire
[01:16:49] <jmkasunich> it can only do series (sucky, high inductance) or unipolar
[01:16:50] <skunkworks> :)
[01:17:03] <fenn> Skullworks: probably something horribly unsuited for the task, but it machined nicely
[01:17:06] <fenn> erf
[01:17:15] <fenn> stupid tab complete
[01:18:10] <skunkworks> fenn: what ever works. :)
[01:18:17] <Guest482> I've got a good memory of all the parts & what they do... just the names... fine... also just saw watchmakers lathes...
[01:18:31] <Jymmmm> jmkasunich #9, first in list?
[01:18:45] <jmkasunich> yeah, that one is definitely better than 10 or 11
[01:18:50] <jmkasunich> looking at the other 9s now
[01:18:52] <Jymmmm> and #8 ?
[01:19:28] <jmkasunich> 8 not nice
[01:19:37] <jmkasunich> high inductance
[01:19:51] <jmkasunich> its a good low speed high torque motor
[01:19:53] <Jymmmm> the curve dont' look so purrty either.
[01:19:54] <jmkasunich> if thats what you need
[01:20:02] <fenn> Guest482: there is a group called "gingery_machines" on yahoo groups that you may wish to look at..
[01:20:11] <jmkasunich> but 9 is better for overall performance
[01:20:44] <Guest482> I saw mention of that while looking up Fonly Lathes via Fab@Home...
[01:21:11] <fenn> also i have a half-completed website about this sort of stuff here: http://fenn.dyndns.org/gingery_machines/
[01:21:28] <Guest482> Say... on another point... are CNC & Lathe guys getting paid well these days?
[01:21:37] <fenn> no
[01:22:13] <Guest482> Getting fucked by the accountants?
[01:22:29] <jmkasunich> getting fscked by the chinese and indians
[01:22:33] <skunkworks> getting f$cked by the economy
[01:22:33] <jmkasunich> and the accountants
[01:22:40] <Guest482> I see...
[01:22:55] <skunkworks> most people on here are mostly hobbiest
[01:23:05] <Guest482> I see...
[01:23:44] <fenn> you'd do better sitting on your butt all day in a do-nothing job
[01:23:57] <jmkasunich> wow... look at the chips coming off this cut: http://www.geocities.com/euxineseaweed/shaperimges018.jpg
[01:24:09] <skunkworks> fenn: my grandfather casted a shaper, mill, lathe and a few other things I forgot.
[01:24:10] <fenn> shear cutter
[01:24:12] <Jymmmm> fenn Hey now... I don't make THAT much at work sitting on my butt watching movies.
[01:24:30] <fenn> rake is probably like 80 degrees on that tool
[01:24:41] <jmkasunich> its still a beast
[01:24:42] <skunkworks> that is about the size of the shaper we have.
[01:24:58] <jmkasunich> 2" wide by 0.030 deep is a heavy cut no matter what the cutter geometry is
[01:25:13] <Jymmmm> * Jymmmm was trying to be funny, but actualyl does sit on his butt at work and watch movies most of the time. And it's ok with the owner too.
[01:25:16] <skunkworks> it rumbles the floor
[01:25:35] <fenn> jymmm what is your nominal job?
[01:26:03] <Jymmmm> fenn: Support engineer at a Tier1 Data Center
[01:26:29] <Guest482> Most 'support engineers' I know watch movies online all day...
[01:26:31] <fenn> are you allowed to call yourself an engineer if you dont have an engineer's certificate?
[01:26:56] <Jymmmm> fenn I dont' call myself that, it's just wants on the job desc title
[01:26:56] <Skullworks> * Skullworks would love his old sit on his ass job telling people how they pooched there Windows system...
[01:27:05] <Guest482> Bosses call you whatever they like... no?
[01:27:15] <Skullworks> but these days I really work
[01:27:24] <Jymmmm> Guest482: Yeah but do they have a 8TB media server at work?
[01:27:40] <Guest482> I know not...
[01:27:47] <fenn> ah now i see why you want a raid array for your jukebox :P
[01:28:03] <Jymmmm> Guest482 We do, one of the NetAdmin's private stock
[01:28:09] <Jymmmm> fenn =)
[01:28:21] <Jymmmm> Even ahe access to it from home as well.
[01:28:38] <Jymmmm> but easier to bring in a 100gb usb hdd and dump it down
[01:29:10] <Guest482> We will drown not in the rising oceans... but in culture from Hollywood...
[01:29:41] <fenn> he's from hollywood so if he's still breathing he must be immune
[01:29:42] <Guest482> Prophesy by Guest482, 4th Century A.D.
[01:30:38] <Jymmmm> We have almost ever TV show out there on the server.... makes it nice to watch it from the beginning
[01:30:55] <Guest482> What? 'TV'?
[01:31:12] <Jymmmm> Guest482 that thing you only have 4 channels of in Ireland =)
[01:31:18] <Guest482> ...from the very first broadcast...
[01:31:38] <Guest482> We have, I'll have you know, as many as....
[01:31:41] <Guest482> 10!
[01:31:43] <Guest482> YES!
[01:31:45] <Jymmmm> lol
[01:31:46] <Guest482> 10 channels!!!!
[01:31:48] <Guest482> :))
[01:31:50] <jmkasunich> Jymmmm: 250 channels of crap is nothing to be proud of
[01:32:26] <jmkasunich> I think the rabbit ears bring in about 5 here
[01:32:37] <Guest482> Actually jmk... our 10 are like 9 of crap & 1 of crap that no one watches coz they hate Irish coz the teachers of Irish are all fucking idiots...
[01:32:39] <jmkasunich> I don't do cable
[01:33:04] <Guest482> I don't even watch terr' TV...
[01:33:06] <Skullworks> I only get 4 here - but then I'm too cheap for cable TV - Cable to me is just for broadband.
[01:33:13] <Guest482> I am Vincent Vega...
[01:33:22] <Jymmmm> jmkasunich: Since we moved, we no longer do $60/mo cable, thus all the media jukebox stuff I've been working on
[01:34:12] <Jymmmm> jmkasunich: I have 3mbps dl that I pay on the dsl if I use it or not, plus the 10GigE pipes at work I'm allowed to use, so...
[01:34:58] <Jymmmm> I may not be able to watch the episode coming on tonight, but I can download it tomorrow =)
[01:36:01] <skunkworks> jymmm: why not satellite?
[01:36:08] <Guest482> If the world ends, you will get an extra 24 hours of not knowing about it...
[01:36:23] <Guest482> Satellite is how they read your every thought skunk...
[01:36:36] <skunkworks> hard to when only one way.
[01:36:54] <Guest482> ...so they say...
[01:37:03] <Jymmmm> Skullworks The difference between cable/satellitte and regular TV is just that it take you longer to find out there's still nothing on TV =)
[01:37:12] <jmkasunich> heh, right
[01:37:20] <jmkasunich> s/nothing/crap/
[01:37:29] <Jymmmm> At least this way it doens't cost me any more than what I'm already paying for on DSL
[01:37:40] <Jymmmm> I sleep, it's downloading.
[01:37:56] <Jymmmm> no commercials, pause and start anytime I want.
[01:38:08] <Jymmmm> rewatch whenever
[01:38:17] <skunkworks> jymmm: I can't say it any differnt other than - arrrrr - yee scurvy fellow.. (satellite)
[01:38:36] <Jymmmm> scurvy?
[01:38:47] <skunkworks> isn;t that a pirate word>
[01:38:48] <Jymmmm> Skullworks ah
[01:38:50] <ejholmgren> ARRRRR YE SALTY DOGS!
[01:39:04] <Jymmmm> Skullworks I never looked into it too much (yet)
[01:39:12] <skunkworks> there is even linux software...
[01:39:14] <Guest482> Dave Gingery seems extremely cool... why do they not show us things like this when @ Uni?
[01:39:46] <jmkasunich> remember what I said about forgetting the crap you learned at school
[01:39:47] <Jymmmm> skunkworks I've considered it, but so far I'm just using stuff I already have out of the junk box,
[01:40:01] <jmkasunich> uni is all about theory, not practice
[01:41:10] <Jymmmm> skunkworks have you tried it or know someone that has?
[01:41:30] <skunkworks> yes
[01:41:31] <Skullworks> this is just so hard core - its what I would do if I wasn't doing 60 hr/wk http://homepage3.nifty.com/amigos/qctp/qctp-e.htm
[01:41:43] <Guest482> I agree mostly... but I'm probably doing a MSc soon..
[01:43:38] <Guest482> I was thinking about Stirling Engines... or something like that...
[01:44:19] <Guest482> Skull what do you do 60 hours @?
[01:44:23] <ejholmgren> "I have been being freedom from adjustment by the sole plate using long time."
[01:44:26] <ejholmgren> base base base base
[01:44:54] <Skullworks> I'm a green button pusher
[01:45:19] <Guest482> I did that, I think... for a while...
[01:45:36] <Guest482> Never 60 hours though...
[01:45:39] <Skullworks> A CNC setup and production worker
[01:45:45] <Skullworks> 5x12
[01:45:47] <Guest482> Oh...
[01:45:52] <Skullworks> 5a to 5p
[01:46:25] <Guest482> Well then... those guys get paid well... they are, after all, almost the only ones who know what the fuck is going on...
[01:46:38] <Guest482> the management doesn't... most of the workers don't...
[01:46:40] <Skullworks> Had to go back to REAL work after the computer corp I was working for outsourced everything overseas
[01:47:07] <Guest482> Ya... Google will soon have to change it's name...
[01:47:20] <Skullworks> and your right about management in my case
[01:48:01] <Skullworks> I expect the company to folde in 2years or less - there running it into the ground
[01:48:09] <Guest482> Skull... I am right about management for most of the companies... they know as little or less than I do...
[01:48:31] <Skullworks> meanwhile I'm banking the OT for the hard times ahead.
[01:48:35] <Guest482> They play 'let's manage'....
[01:48:52] <Guest482> I dislike banks...
[01:49:12] <skunkworks> guest482: where are you from?
[01:49:15] <Guest482> Always buy Gold, other precious metals... or perhaps collectables... stamps or something else traditional...
[01:49:18] <Guest482> Ireland...
[01:49:26] <Guest482> We are doing extremely well here...
[01:49:32] <Skullworks> yes but banks have there uses
[01:49:37] <skunkworks> :) went there last year.
[01:50:00] <Guest482> 10% corporation tax... lowest in Europe... practically an English speaking, European, tax haven...
[01:50:00] <skunkworks> did a fly and drive. We probably drove you off the road once or twice.
[01:50:11] <Skullworks> I like earning interest on my mortgage payment before the check clears
[01:50:20] <Guest482> I run... I hate bastards who drive early in the morning...
[01:50:46] <Guest482> Drive all other times of day... but not between 6.30 & 7.30
[01:51:00] <Guest482> :)
[01:51:25] <ejholmgren> I drive a large crappy van
[01:51:33] <ejholmgren> it makes merging really easy
[01:51:38] <Guest482> Is everyone here a Yank...?
[01:51:48] <ejholmgren> no
[01:51:54] <Skullworks> * Skullworks says he never exceeds 120Kph on surface streets @ 4am
[01:51:59] <jmkasunich> this time of day it leans that way
[01:52:11] <jmkasunich> cause its sleepy time in EU
[01:52:24] <Guest482> Yes... I should go...
[01:52:31] <Guest482> ....& make some coffee...
[01:52:34] <Guest482> :)
[01:52:54] <Guest482> Any Canucks?
[01:52:55] <jmkasunich> I think robin_sz is still here, he's a brit
[01:53:03] <jmkasunich> a-l-p-h-a is canadian
[01:53:12] <jmkasunich> alex_joni is sleeping - he's romanian
[01:53:28] <robin_sz> * robin_sz puts on his Union Jack underpants
[01:53:34] <Guest482> Cool...
[01:53:47] <Guest482> Good mix of folks...
[01:53:56] <robin_sz> Guest482> Is everyone here a Yank...?
[01:54:00] <robin_sz> let me guess ...
[01:54:09] <Guest482> Ireland.
[01:54:11] <robin_sz> you work for the diplomatic service, right?
[01:54:16] <Guest482> Yap...
[01:54:28] <robin_sz> which bit of ireland?
[01:54:49] <Guest482> Dundalk, Dublin & across westward...
[01:55:06] <Guest482> Sometimes even Belfast...
[01:55:15] <robin_sz> never been to the north
[01:55:37] <robin_sz> wifes family from dublin
[01:55:51] <Guest482> Cool...
[01:56:08] <Guest482> So you professional or hobbiest?
[01:56:13] <robin_sz> both
[01:56:13] <Guest482> @ lathe work?
[01:56:18] <Guest482> Ah...
[01:56:21] <robin_sz> lathes? hobbiest
[01:56:29] <fenn> it's hobbyist btw
[01:56:35] <Guest482> I actually came here via RepRap which is Uni of Bath...
[01:56:41] <ejholmgren> hobbeast
[01:56:59] <fenn> hobbesist, from the philosophy of hobbes
[01:57:00] <ejholmgren> * ejholmgren growls
[01:57:17] <Guest482> I was using the 'cute' spelling I saw earlier...
[01:57:30] <robin_sz> I vaguely know bath uni ... I just remeber the big hills :)
[01:57:49] <Guest482> Being one who is the most hobbiest...
[01:57:57] <robin_sz> I have relative in Bradford on Avon, just ouside
[01:58:36] <Guest482> I was manufactured 'n London town...
[01:58:40] <robin_sz> this lot do CNC mills, Im the cnc laser and robots guy
[01:58:52] <Guest482> Robots...
[01:58:57] <Guest482> Mmmmm....
[01:59:16] <robin_sz> 6 axis industrial bot .. alex_joni is the guy for robots
[01:59:48] <Guest482> One of my claims to fame was that I got an Intellidex Robot working during my Diploma year that no one else could get working....
[01:59:56] <robin_sz> if it doesnt pull 10KVA of 3 phase its too small for me :)
[02:00:07] <Skullworks> Love to retro fit the Nd-YAg laser - but not sure EMC is ready for variable capacitence feedback loop.
[02:00:07] <Guest482> There was no instructions even online... no fucking anything...
[02:00:33] <Guest482> I see...
[02:00:47] <Guest482> So not the Sony robodog...
[02:00:56] <robin_sz> nope :)
[02:01:25] <Guest482> Well the Intellidex was just a big fucking arm that no one could remember how to program...
[02:01:31] <Skullworks> Try pleading with an old GMF - Run, PLEASE...
[02:01:40] <Guest482> I 'fluked' it...
[02:01:45] <robin_sz> http://www.redpoint.org.uk/photos/upload/robot/Image018.jpg
[02:02:48] <Guest482> It doesn't look the least like a Dalek... bummer...
[02:03:13] <fenn> looks more like a big red commie triffid
[02:03:26] <Skullworks> some pics from work in this writeup http://www.roboticsonline.com/public/articles/index.cfm?cat=294
[02:03:31] <robin_sz> Intelidex 605?
[02:03:44] <Guest482> I honestly cannot recall...
[02:04:56] <robin_sz> 'k
[02:05:21] <Guest482> I actually asked for my report back... last June.. but it was 6 or so years...
[02:05:21] <robin_sz> right bedtime ... the staff are on a 7am call tomorow .. I'd better be there to let em in
[02:05:30] <Guest482> K
[02:05:35] <robin_sz> later guys ..

[02:17:47] <Guest482> The Chinese have no Year of the Duck...
[02:17:54] <Guest482> This seems unfair...
[02:17:59] <Guest482> :|
[02:18:58] <Skullworks> Manderin duck - too greasy for me
[02:22:26] <a-l-p-h-a> Peking Duck... yummmy
[02:22:48] <a-l-p-h-a> it's like the Chinese Taco. The Mexicans copied the chinese, wrapping something up in a flour wrap.
[02:24:15] <Skullworks> Mex food is all modular
[02:24:24] <Skullworks> and its all good
[02:25:31] <Guest482> Yes... Mex is good...
[02:25:34] <a-l-p-h-a> ALL good?
[02:25:48] <a-l-p-h-a> remember that last re-fried bean burrito...
[02:25:50] <a-l-p-h-a> was that good coming out?
[02:25:57] <a-l-p-h-a> NO.
[02:26:02] <a-l-p-h-a> so... it's not ALL good.
[02:26:07] <Guest482> Alpha, you're Canadian, right?
[02:35:43] <Skullworks> Burrito's have nothing on Viet food - burns both ways
[02:36:25] <a-l-p-h-a> Viet food... I dunno about that... depends on what you eat... I usually have pho, or vermicilli / grilled something / spring roll.
[02:36:44] <a-l-p-h-a> Guest482, yup. Canadian, every single atom.
[02:37:46] <Skullworks> I had some clear soup that could prove the theory of spontainious human cumbustion.
[02:38:24] <Skullworks> * Skullworks can't type tonite...
[02:51:14] <Guest482> Toronto/Montreal?
[02:52:21] <jmkasunich> heh, my stepper sounds like a gas engine
[02:52:30] <jmkasunich> its doing 272 rpm (average)
[02:52:40] <jmkasunich> stopping and starting 4 times per revolution
[02:52:49] <DanielFalck> tomp: are you around? join #cam
[02:52:56] <jmkasunich> peak speed 500 rpm
[02:53:03] <jmkasunich> 0 to 500 in 9mS
[03:01:28] <tomp> DanielFalck:cu@cam
[03:04:39] <jepler> tomp: I'm sorry I haven't taken the time to review your pyvcp enhancements yet. Probably you should ask someone else to do it, or send it to the developers' mailing list in patch format.
[03:23:56] <jmkasunich> is Peter Wallace lurking here?
[03:23:59] <CIA-19> 03cradek 07TRUNK * 10emc2/src/libnml/posemath/_posemath.c: simple doc fixes
[03:24:00] <CIA-19> 03cradek 07TRUNK * 10emc2/src/emc/kinematics/tc.c: simple doc fixes
[03:31:16] <Guest482> I'm off... see you all again soon...
[03:40:44] <cradek> any idea why he can't email you?
[03:40:50] <jmkasunich> no clue
[03:41:02] <jmkasunich> I'm replying now, and asking him to send the bounce messages to my yahoo address
[03:41:09] <cradek> good idea
[03:41:24] <cradek> have you tried gmail? I bet it's better than your current webmail
[03:41:41] <jmkasunich> no, maybe I should
[03:41:50] <cradek> I can send you an invite
[03:41:54] <jmkasunich> I think you sent me an invite once, no clue what I did with it
[03:42:01] <cradek> I'll do it again
[03:42:01] <jmkasunich> something turned me off on the idea of gmail tho
[03:42:06] <jmkasunich> don't recall what it was
[03:42:28] <cradek> was it that all webmail sucks?
[03:42:34] <jmkasunich> ;-P
[03:42:46] <jepler> there's the google data retention policy and the "targeted" ads
[03:43:12] <jmkasunich> yeah, general "I don't like the terms of service" concerns are what I recall
[03:43:49] <cradek> I can't disagree with that
[03:44:31] <jmkasunich> I don't see myself changing to gmail (or yahoo) as my primary address
[03:44:41] <jmkasunich> and how many backup addresses does one need?
[03:44:50] <cradek> well, I have none
[03:45:00] <jmkasunich> especially since I don't check the yahoo one unless I'm expecting something
[03:45:13] <jmkasunich> I use the yahoo one when I don't want to give out my real one
[03:45:26] <jmkasunich> you know, websites that say "register and we'll mail you a password"
[03:45:31] <jmkasunich> like cnczone
[03:45:38] <jmkasunich> and the xylinx software
[03:49:21] <Jymmm> I'm Baaaaacck!

[04:19:21] <a-l-p-h-a> jmkasunich, I'm readin gup on emc-users... what's going on with this step generator?
[04:20:22] <jmkasunich> pete is doing the hardware (has done it already pretty much)
[04:20:39] <jmkasunich> I haven't seen the FPGA firmware yet, so driver isn't started yet
[04:22:54] <a-l-p-h-a> COOL.
[04:22:56] <a-l-p-h-a> so fast.
[04:23:32] <a-l-p-h-a> I've love to learn this stuff...
[04:23:36] <a-l-p-h-a> I'd
[04:23:56] <Jymmm> Learn FPGA Programming in 24 hours, by jmkasunich
[04:24:55] <jmkasunich> heh, 24 days mabye
[04:25:02] <Jymmm> months
[04:28:02] <steves_logging> steves_logging is now known as steve_stallings
[04:31:38] <steve_stallings> jmkasunich - earlier you mentioned that your stepper drivers were reaching 50 degres C, was this without a heatsink?
[04:31:53] <jmkasunich> not the drivers, the motors
[04:32:03] <jmkasunich> the drivers are on a sink, and are barely getting warm
[04:32:12] <steve_stallings> aah, that is different 8-)
[04:32:12] <jmkasunich> the motors topped out at about 60C
[04:32:13] <Jymmm> jmkasunich what the?!
[04:32:25] <Jymmm> jmkasunich what voltage/amperage?
[04:33:12] <jmkasunich> 6.1A 2.1V steppers, 55V DC supply
[04:33:25] <Jymmm> I got luck and bought a non-contact thrometer for very purpose
[04:33:26] <jmkasunich> the steppers we were talking about an hour ago from keling
[04:33:42] <Jymmm> that's kinda weid to get THAT hot, isn't it?
[04:34:12] <steve_stallings> with 55 volt power source driving a motor that has 2.1 volt drop at rated current your voltage ratio is a bit high and may be causing excess heat due to chop ripple and hystersis in the iron
[04:34:45] <jmkasunich> well, its a nominal 48V supply
[04:35:15] <jmkasunich> unloaded is 55V, but it doesn't drop much (so far - only running one motor)
[04:35:27] <jmkasunich> it has +/-10% taps, so I might tap it down to a lower voltage
[04:35:56] <steve_stallings> Mariss recommends a ratio of 20 or less on his drives except for the G203 that has more intelligent recirculation management
[04:36:15] <Jymmm> can you "turn down" the amperage on geckos?
[04:36:31] <ejholmgren> yes
[04:36:45] <ejholmgren> I think so at least ... with a resistor?
[04:37:03] <Jymmm> Xylotex, there is a pot on the board I can set.
[04:37:08] <jmkasunich> I thought mariss recommended 10-25
[04:37:22] <jmkasunich> 52,5 = 25 * 2.1
[04:37:32] <jmkasunich> yes, there is a resistor to set the current
[04:38:05] <Jymmm> resistor or a pot?
[04:38:29] <ejholmgren> resistor
[04:38:35] <Jymmm> ug
[04:39:18] <jmkasunich> whats wrong with that
[04:39:28] <jmkasunich> don't have to worry about it getting bumped or anything
[04:40:10] <ejholmgren> or you can choose your resistor in less than ideal light ... and get the multiplier way off
[04:40:26] <ejholmgren> I thought I'd broken something on evening
[04:41:41] <ejholmgren> there's a table silkscreened on the case with amperage/resistor values, I believe
[04:41:58] <steve_stallings> OK - I see the latest manuals mention up to a 25x voltage ratio. Still the non-G203 drives run something similar to anti-phase drive and the ripple current is significant with higher supply voltages. As usual you get to trade off high speed performance for motor heating.
[04:56:02] <tomp> jepler: no problem. i was just complimenting your work on the spline, thanks
[04:57:11] <tomp> e or i? i thought the spline was neat

[15:24:57] <Martin_Lundstrom> Hello everyone
[16:00:14] <Guest299> hello
[16:01:01] <jepler> Guest299: welcome
[16:01:15] <Guest299> ty
[16:02:25] <Guest299> im try to find out how to make emc2.1 home my mill with 3 shared limit/home switches
[16:02:41] <Guest299> can only make 1 axis work
[16:06:58] <Guest299> cant a single limit/home switch share a pin?
[16:09:40] <cradek> yes you can put all homes and limits on one pin if you want
[16:09:58] <cradek> what have you done so far, and where are you stuck?
[16:11:30] <Guest299> if i put one axis on 2 pins it will operate as a home/limit switch
[16:11:56] <Guest299> if i add an axis only htat 1 will home
[16:12:00] <Guest299> that
[16:12:27] <Guest299> if i put on the same pin it wont home either
[16:13:20] <Guest299> only way so far is to have 2 pins on axis
[16:13:43] <cradek> can you put your hal file changes on www.pastebin.ca, I need more specific information about what you've done in order to help
[16:14:22] <Guest299> sure can or I can email also
[16:14:40] <cradek> if you use pastebin.ca, anyone here can help
[16:15:18] <Guest299> k,have never used it before,first time in room also
[16:15:41] <Guest299> joined emc mail list this morning also
[16:15:48] <cradek> cool
[16:16:35] <rayh> If you have multiple axes home/limit to a single pin you will need to move each axis away from it's switches before you home the next.
[16:16:35] <Guest299> hate to be a bother but i been on these limit switches for the last couple of days
[16:17:23] <cradek> brb
[16:17:34] <Guest299> k
[16:17:59] <Guest299> you mean move axis in jog before you home?
[16:18:30] <rayh> There is a home offset in the ini file which will move the axis and set the moved position as home.
[16:19:09] <rayh> after the axis has touched the switch.
[16:19:11] <Guest299> my home offset is 0 im my ini file
[16:20:29] <Guest299> gonna log off here,gonna get on my linux box in the garage
[16:20:34] <rayh> I set that value to 0.25 (inch) on my machines and it moves off the switch.
[16:20:38] <Guest299> brb
[16:20:42] <rayh> k
[16:30:42] <cradek> also be sure to set HOME_IS_SHARED for safety and HOME_SEQUENCE for convenience (home all)
[16:33:44] <Guest299> i added HOME_IS_SHARED,and HOME_SEQUENCE to my ini file,what should the home_seq value be?
[16:34:14] <cradek> you can set any sequence you want
[16:34:21] <Guest299> have used 0 or 1 for the home is shared,seems to have no effect
[16:34:43] <Guest299> what would be an example seq for 3 axis?
[16:35:18] <rayh> I'd get it homing on each axis before I worry about sequential homes.
[16:35:19] <cradek> 0, 1, and 2
[16:35:28] <cradek> true
[16:35:38] <cradek> but HOME_IS_SHARED=1 on all axes is very important
[16:35:40] <jepler> You would set HOME_IS_SHARED = 1 on all axes
[16:35:52] <rayh> Once a home switch closes, any home command will see that axis as already homed.
[16:35:52] <cradek> http://www.linuxcnc.org/docs/html/config/ini_homing/ini_homing.html
[16:36:21] <jepler> that way you will get a message that says "Cannot home while shared home switch is closed", instead of having the machine move in an undesired fashion
[16:36:21] <cradek> rayh: not true - it will back off the switch and then home
[16:37:41] <cradek> that's why HOME_IS_SHARED is important - otherwise if the other axis is on the switch, this axis will go the wrong way and crash (never finding the switch)
[16:37:47] <Guest299> would "0,1,2" be a valid entry for home seq,are commas allowed
[16:38:04] <jepler> Guest299: [AXIS_0] HOME_SEQUENCE=0 [AXIS_1] HOME_SEQUENCE=1
[16:38:14] <jepler> use one number for HOME_SEQUENCE in each AXIS
[16:38:21] <Guest299> got ya
[16:38:30] <cradek> also [AXIS_0] HOME_IS_SHARED=1 [AXIS_1] HOME_IS_SHARED=1 ...
[16:39:07] <jepler> first the axis (or axes) with HOME_SEQUENCE=0 are homed, then HOME_SEQUENCE=1, and so on
[16:39:31] <Guest299> k,let me give it a whirl
[16:39:39] <rayh> It is getting deep here. There are simpler ways to start this process for a newbee
[16:41:35] <cradek> well that's helpful
[16:46:42] <Guest299> still wouldnt work
[16:47:40] <cradek> can you describe exactly what doesn't work, and also put your hal and ini files on pastebin.ca
[16:47:52] <cradek> we're just guessing otherwise
[16:48:01] <Guest299> set the home seq correctly,and all home is shared to 1,also ingnore limits is set to yes
[16:48:11] <cradek> ok good
[16:48:46] <Guest299> when you try to home an axis it just triggers the limit switch
[16:49:16] <cradek> ok let's see your hal file to see if you have it wired up right
[16:49:25] <Guest299> want me to put my ini file on pastebin
[16:49:54] <CIA-19> 03cradek 07TRUNK * 10emc2/docs/src/config/ini_homing.lyx: initial backoff was not described

[16:51:13] <Guest299> ?
[16:51:42] <fenn_> fenn_ is now known as fenn
[16:51:45] <jepler> Guest299: yes, please put your .ini and .hal files on pastebin
[16:51:59] <Guest299> k
[16:55:37] <Guest299> just put em on there
[16:56:06] <jepler> you need to give us the URL it assigned to your submission
[16:56:20] <Guest299> k,brb
[16:56:31] <jepler> er -- I found your submission, but you need to put the *contents* of the files there, no just the filenames
[16:56:33] <jepler> *not* just
[16:57:55] <Guest299> k,will do again
[17:01:13] <Guest299> how bout now
[17:02:48] <cradek> much better, found the hal file
[17:02:53] <Guest299> cool
[17:03:00] <Guest299> my first time,lol
[17:03:12] <cradek> don't see the ini file
[17:03:28] <cradek> hal file: http://pastebin.ca/363699
[17:03:47] <Guest299> i wonder if it wrote over it,i sent it first
[17:04:05] <Guest299> will send again
[17:04:11] <cradek> ini file: http://pastebin.ca/363697
[17:04:13] <cradek> found it
[17:04:26] <eholmgren> there's some wicked skew going on in that manual
[17:04:27] <cradek> when you do the paste, it gives a URL, then you can copy that here so we can find it
[17:04:37] <jepler> linkps parport.0.pin-12-in-not => homeswitches
[17:04:44] <jepler> linkps parport.0.pin-12-in-not limit-reached # connect this signal to pin 15 on the parport
[17:05:02] <jepler> a pin (like parport.0.pin-12-in-not) can only be hooked to one signal (like homeswitches)
[17:05:21] <jepler> the second "linkps" has the effect of removing pin-12-in-not from homeswitches and attaching it to limit-reached
[17:06:07] <cradek> brb
[17:06:15] <Guest299> 363710 for ini file
[17:07:37] <cradek> I see you are set up for the first sequence with latch negative - this means the home location is located as you back off the switch
[17:07:45] <Guest299> yep
[17:07:51] <cradek> but jepler definitely spotted the problem above
[17:08:16] <jepler> Guest299: do you want to home to the limit switch, or are they supposed to be different pin numbers for home and limit switches?
[17:09:02] <cradek> (also you need to set HOME or HOME_OFFSET nonzero so after homing each axis, it moves away from the switch)
[17:09:05] <Guest299> yes,want to home to the limit switch
[17:09:18] <jepler> OK
[17:09:41] <Guest299> does it have to move off the switch?
[17:09:54] <cradek> yes, otherwise you can't home the other axes
[17:10:18] <jepler> first you need to fix your hal file so that pin-12-in-not is connected to all the things it should be
[17:10:21] <cradek> well I guess with your setup, it will be off the switch after homing, but just barely
[17:10:33] <jepler> the second "linkps" has the effect of removing pin-12-in-not from homeswitches and attaching it to limit-reached
[17:10:34] <cradek> jepler is right, sorry for distracting
[17:10:43] <Guest299> k
[17:10:49] <jepler> so have only one "linkps" command, such as 'linkps parport.0.pin-12-in-not => switches'
[17:11:22] <jepler> and then link 'switches' to all of the home and limit pins: 'linksp switches => axis.0.neg-lim-sw-in', 'linksp switches => axis.0.home-sw-in' and so on
[17:11:40] <Guest299> would like to be able to use pin 11 for x home,limit,12 for y,13 for z
[17:11:57] <Guest299> that is my ultimate goal
[17:12:38] <jepler> that will be fine too
[17:12:50] <jepler> in that case you would have 3 signals, perhaps named "Xswitches", "Yswitches" and "Zswitches"
[17:13:09] <Guest299> k
[17:15:20] <cradek> if you do that, they can all home at the same time, which is nice
[17:16:17] <jepler> this shows how the HAL commands would be for 3 parallel port pins, or for just 1 pin: http://pastebin.ca/363733
[17:16:32] <jepler> oops, except there's at least one typo in the second part
[17:16:47] <Guest299> of mine?
[17:16:57] <jepler> no, of my pastebin
[17:17:03] <jepler> fixed: http://pastebin.ca/363737
[17:18:30] <Guest299> k,im looking at it now
[17:18:45] <Guest299> let me try that right quick
[17:28:36] <Guest299> doesnt like the new signals,wont start emc
[17:29:05] <jepler> start emc from the terminal if necessary so you can see the errors
[17:29:20] <jepler> if you don't know what they mean, then put them in a new pastebin and I'll take a look
[17:29:25] <jepler> it's most likely that I had a typo somewhere
[17:30:56] <Guest299> i turned the old signals off,ex home switch and limits,did i need to leave them on?
[17:31:06] <SWPadnos> the last group of linkps all refer to axis 0, not 0,1, and 2
[17:31:32] <jepler> oops -- yeah, thanks for spotting that
[17:31:54] <jepler> should be axis.0 for the first 3, then axis.1, then axis.2
[17:31:59] <SWPadnos> actually, they all refer to axis 0 (are the upper sets of links needed?)
[17:32:17] <jepler> SWPadnos: it's two choices: first, if you're using 3 input pins. second if you're using only 1 input pin.
[17:32:27] <SWPadnos> got it
[17:33:56] <Guest299> ?
[17:34:49] <SWPadnos> like this: http://pastebin.ca/363761
[17:35:24] <SWPadnos> use either the lines above the #-------------------------- (for separate switches) or the ones below for one shared switch
[17:36:27] <lerneaen_hydra> 'lo, anyone here?
[17:36:33] <SWPadnos> nope
[17:36:43] <Guest299> let me try that
[17:36:47] <Guest299> brb
[17:36:55] <lerneaen_hydra> damn, better wait a while
[17:37:13] <lerneaen_hydra> SWPadnos, you run linux?
[17:37:19] <SWPadnos> sometimes
[17:37:35] <lerneaen_hydra> played with grub before?
[17:37:38] <SWPadnos> mostly for gaming these days (that's a turnaround, huh?)
[17:37:45] <SWPadnos> yes, some
[17:37:46] <lerneaen_hydra> heh
[17:37:48] <lerneaen_hydra> nice
[17:38:14] <lerneaen_hydra> any idea of why a kernel update and grub update would end up with a nonbootable system?
[17:38:26] <lerneaen_hydra> I get an error17, partition not readable
[17:39:14] <SWPadnos> hmmm. no other changes to the machine )BIOS changes ...)
[17:39:24] <lerneaen_hydra> and I've tried all possible combinations of root(HDx,0) and dev/sdx1
[17:39:29] <lerneaen_hydra> nope, no bios changes
[17:39:36] <lerneaen_hydra> no hardware changes
[17:39:42] <SWPadnos> have you seen this or soemthing like it? http://forums.gentoo.org/viewtopic.php?t=120802
[17:39:45] <lerneaen_hydra> partition is not dead as knoppix can read it fine
[17:40:20] <lerneaen_hydra> damn brb
[17:40:29] <SWPadnos> seeya
[17:45:11] <Guest299> says hal error allswitches not found when i try to use allswitch command
[17:45:49] <SWPadnos> oops - one other typo. let me fix that and repost it
[17:46:52] <SWPadnos> http://pastebin.ca/363777
[17:47:02] <Guest299> k,brb
[17:47:03] <SWPadnos> all the linksp and linkps commands had been swapped
[17:51:21] <Guest299> k,let me try that
[17:59:34] <Guest299> ok,now it will boot into emc
[17:59:42] <SWPadnos> excellent
[17:59:50] <Guest299> but not homing yet
[17:59:59] <SWPadnos> bummer
[18:00:40] <Guest299> for real,but yet closer
[18:01:18] <Guest299> im wondering if its in the ini file now
[18:01:52] <SWPadnos> I'm looking at that now - have you changed the ini since posting it to pastebin?
[18:02:01] <Guest299> nope
[18:02:06] <SWPadnos> okl
[18:02:07] <SWPadnos> ok
[18:03:12] <lerneaen_hydra> iB
[18:03:16] <lerneaen_hydra> *iab
[18:03:21] <SWPadnos> I think Ray suggested adding in a "home_offset" to move off the switches
[18:06:07] <Guest299> i just tried it on the y axis only and it worked
[18:06:24] <SWPadnos> good. you'll need to do it on all axes, since they share the same input
[18:06:49] <Guest299> but wont work on all axes
[18:07:04] <SWPadnos> what does it do?
[18:07:17] <SWPadnos> actually, what did you do, and how did it work after that? :)
[18:08:00] <Guest299> you start homing an axis,make the switch,lights go red,motion stops,no home green light
[18:09:18] <SWPadnos> err - I'm not sure I can help you here. I don't have a machine running EMC at the moment, and I don't really know what the UIs do when you home
[18:09:23] <Guest299> if i change to just 1 axis it does same thing,but give green home light
[18:09:43] <SWPadnos> I think there's a "home all" key in AXIS, but I don't remember what it is
[18:09:53] <SWPadnos> that should home each axis in sequence
[18:09:55] <lerneaen_hydra> SWPadnos, looks like I got it working, the command-line in grub and find <filename> is what saved me
[18:10:18] <SWPadnos> lerneaen_hydra, cool
[18:10:38] <Guest299> im actually wanting it to be 11 for xhmoe/limit,12 for y,13 for z
[18:11:15] <SWPadnos> ok. you should use the upper set of signals then, and set HOME_IS_SHARED to 0 for each axis
[18:11:27] <SWPadnos> err - the upper set of hal commands from the pastebin
[18:11:28] <Guest299> it actually does work for the first time ever using a single pin for axis home,limit
[18:11:43] <SWPadnos> oops - ignore what I just said :)
[18:12:06] <Guest299> k
[18:12:25] <Guest299> lemmee try something right quick
[18:12:31] <tomp> lerneaen_hydra: find vmlinuz... or initrd... ?
[18:13:42] <lerneaen_hydra> tomp, find /boot/grub/stage1
[18:14:43] <tomp> whoa! it missed that.. yeh grub cmd line is great, but skimpy with on-line on docs when it wont boot
[18:17:11] <lerneaen_hydra> err, this is starting to scare me, xorg is dead now
[18:17:37] <lerneaen_hydra> oh
[18:17:39] <lerneaen_hydra> wait
[18:18:01] <lerneaen_hydra> I run the binary driver, it needs special kernel interlinking, which is probably dead now that I've updated the kernel
[18:19:30] <lerneaen_hydra> it seems kind of scary that a grub update would do something that results in an unbootable system
[18:20:06] <Guest299> dude i added an axis,now i ca do y an z,awesome
[18:20:34] <Guest299> fixing to wire the x in on pin 11
[18:20:50] <Guest299> have 12 and 13 working now
[18:21:20] <Guest299> ive spent 3 days on this so far,im starting to see some light
[18:21:30] <SWPadnos> great
[18:22:24] <Guest299> i knew it had to work,never found that switch command you gave me in any examples
[18:22:49] <SWPadnos> which switch command?
[18:23:16] <Guest299> allswitch
[18:23:33] <SWPadnos> oh - connecting everything to one signal
[18:23:57] <Guest299> im trying to make an ini and hal file so that a mach3 user can try this software
[18:23:59] <Guest299> yes
[18:24:21] <SWPadnos> I had considered doing that as well, but Mach gets all screwed up on my machine
[18:24:31] <SWPadnos> I have to reboot after using it
[18:25:17] <Guest299> runs good on mine,have done 3 retrofits with it also,so have done 4 in all
[18:25:38] <Guest299> but have never been able to make emc work till now
[18:25:40] <lerneaen_hydra_> lerneaen_hydra_ is now known as lerneaen_hydra
[18:26:11] <SWPadnos> that's cool. my computer is a somewhat older Athlon with Windows 2000, and if I have anything like Winamp running when I run Mach, all system timers get totally screwed up until I reboot
[18:26:42] <Guest299> this appears to be an awesome program,just hard for a regular joe to understand
[18:26:42] <SWPadnos> so things like the pause before a tooltip or menu pops up are 5 seconds or so instead of 0.5
[18:27:06] <SWPadnos> I agree - it can do just about everything, so it's harder to tell it which subset of features to use :)
[18:27:08] <Guest299> when i run it i dont have anything else running
[18:28:20] <Guest299> true,gonna find whats needed for a regular setup like a mach setup and save it
[18:28:41] <crepincdotcom> well, if fenn were here he'd be laughing at me right now
[18:29:06] <SWPadnos> it should be pretty easy to make a stepper config that has the same pinouts as Mach (though I don't know what those pinouts are)
[18:29:08] <crepincdotcom> damn open loop steppers are a bad idea
[18:29:39] <Guest299> i agree fully,just all i have right now
[18:29:52] <crepincdotcom> me too :-(
[18:30:09] <crepincdotcom> for some unknown reason, i loose about 2 steps per several rotations
[18:30:10] <Guest299> it what my boss bridgeport had
[18:30:18] <crepincdotcom> so throughout a board i get more and more error
[18:30:58] <Guest299> mine actually positions very well in mach,havent made a part with emc yet
[18:31:15] <crepincdotcom> wahts mach
[18:31:30] <SWPadnos> Mach3 is a Windows based CNC controller
[18:31:35] <crepincdotcom> ahh
[18:31:36] <Guest299> a windows cnc program
[18:31:42] <SWPadnos> http://www.artofcnc.ca
[18:31:49] <SWPadnos> I think
[18:31:53] <Guest299> yep
[18:32:09] <SWPadnos> it's "the competition" :)
[18:32:16] <Guest299> im gonna make this work,done set my mind to it
[18:32:19] <crepincdotcom> lol
[18:32:45] <Guest299> this new version looks like it could be the 1
[18:33:06] <SWPadnos> Guest299, when you do, it would be great if you could put up a page on the wiki
[18:33:07] <Guest299> brb,gonna wire in my x switch
[18:33:32] <SWPadnos> also, having a "mach stepper" config in the distributed packages would probably be a good thing
[18:33:41] <Guest299> i sure will,jon elson said it was a good idea,so did alex joni
[18:33:45] <SWPadnos> (especially on the LiveCD, so people could easily try it))
[18:33:51] <SWPadnos> great
[18:34:43] <Guest299> thats my whole goal,so guys that can setup a mach machine can try this without having to rewire everything
[18:35:08] <Guest299> alex said he would try to work it in when im done
[18:35:36] <Guest299> and you have been a tremendous help
[18:36:00] <Guest299> brb
[18:36:13] <steve_stallings> steve_stallings is now known as steves_logging
[18:40:35] <Guest299> yep they all wor,x,y and z
[18:40:47] <Guest299> work
[18:40:49] <SWPadnos> awesome
[18:40:58] <Guest299> for real
[18:41:13] <Guest299> you just dont know how awesome
[18:41:42] <Guest299> have you ever used the debounce command
[18:41:57] <SWPadnos> let us know your impression of how well EMC2 works relative to Mach
[18:42:24] <SWPadnos> no - what are you trying to do?
[18:42:50] <Guest299> stop some signal noise
[18:43:31] <SWPadnos> when you say ?debounce command", what do you mean? there is a debounce component in EMC, is there a debounce setting in Mach?
[18:43:49] <SWPadnos> (I know what debounce is. I'm an electrical engineer :) )
[18:43:51] <Guest299> mach has a setting for it,i noticed there was a command for it,but dont know how to use
[18:44:07] <SWPadnos> ok
[18:44:10] <Guest299> yes mach has a setting for it
[18:44:44] <SWPadnos> what are the units for the mach setting?
[18:44:51] <SWPadnos> step periods, micro/nanoseconds ...
[18:44:55] <SWPadnos> arbitrary
[18:44:58] <Guest299> on every machine ive done you have to set a value for it,or it will think a limit was made
[18:45:29] <Guest299> let me check
[18:50:31] <Guest299> cant get to it right now,would have to reboot my linux box
[18:50:45] <SWPadnos> ok - no worries
[18:50:47] <SWPadnos> tjere
[18:50:55] <SWPadnos> there's a component called "debounce"
[18:51:03] <Guest299> but i turned my machine power on and its not doing it like before
[18:51:27] <Martin_Lundstrom> anyone: Where to get bored HTD pulleys?
[18:51:32] <SWPadnos> you set the number of samples that a signal has to remain the same
[18:51:44] <Guest299> cool
[18:52:20] <SWPadnos> this can be done for multiple groups of signals. each group can have as many as 8 inputs (I think), and each group has a separate filter count setting
[18:52:35] <Guest299> in mach you usually set the value to 2000 and that will clear up a false limit signal,home never does it
[18:52:37] <SWPadnos> each group can also sample at a different rate - the filters don't have to run in the same thread
[18:53:07] <Guest299> this is some amazing software
[18:53:09] <SWPadnos> Martin_Lundstrom, http://www.sdp-si.com may bore pulleys for you, but pulleys usually are sold with small holes with the expectation that you'll bore them out yourself
[18:53:20] <SWPadnos> Guest299, have you read the HAL integrator's manual?
[18:53:47] <SWPadnos> it sounds like you would get a lot out of it - there are a lot of components to HAL, and you can do some pretty amaxing things with them
[18:53:47] <crepincdotcom> anyone familiar with the L297?
[18:53:48] <Guest299> been all over it last weekend
[18:53:53] <SWPadnos> ok
[18:54:00] <SWPadnos> a very recent copy?
[18:54:05] <SWPadnos> crepincdotcom, buy geckos :)
[18:54:10] <Martin_Lundstrom> SWPadnos, ok is that in US?
[18:54:11] <crepincdotcom> noooooooooo
[18:54:15] <Guest299> with my new 2.1
[18:54:18] <SWPadnos> Martin_Lundstrom, yes, they are
[18:54:32] <Guest299> i have some geckos
[18:54:33] <crepincdotcom> SWPadnos: 1) no money, 2) I like building things 3) see #1
[18:54:58] <SWPadnos> Guest299, ok - that's good. I don't remember if the HAL manual is included in the users guide now, but there have been a lot of changes in the last 6 months to a year
[18:54:57] <Guest299> lol,thats my line
[18:55:05] <SWPadnos> crepincdotcom, ok :)
[18:55:17] <Guest299> it doesnt have the allswitch
[18:55:41] <crepincdotcom> ok fine, talk to me about the gecko for a second
[18:55:46] <crepincdotcom> does it work out of the box with emc?
[18:55:54] <SWPadnos> crepincdotcom, as long as you're doing this for the fun of it, that's fine. if you want to get actual work done, then you should do a whole lotta learning before trying to build a step motor driver :)
[18:55:57] <crepincdotcom> does it support input like limit switches or encoders?
[18:56:23] <SWPadnos> the motor drivers don't deal with limits (though they have enable/disable inputs)
[18:56:31] <crepincdotcom> SWPadnos: well i got SOME work done before i had issue, but the driver i built to start with works perfectly
[18:56:37] <SWPadnos> the step drivers don't have encoder inputs, since they aren't generally needed for steppers
[18:56:39] <Guest299> mine do,jst need to set correct steps per inch
[18:56:46] <crepincdotcom> only issue is that i built it for unipolar and i want to use bipolar motors
[18:57:02] <SWPadnos> pminmo.com and others have plans you can build
[18:57:05] <crepincdotcom> the issue is that if it ties up the ppt port, then i cant do inputs
[18:57:24] <Guest299> why not
[18:57:35] <crepincdotcom> ...because something is already connected to it
[18:57:37] <SWPadnos> you need to count up the number of I/Os you need, then figure out what hardware is needed to get that many
[18:57:44] <Guest299> i have inputs
[18:57:56] <crepincdotcom> i have 8 pins: 2 for each motor leaves me 2
[18:57:59] <crepincdotcom> == not enough for input
[18:57:59] <Guest299> how many do you need
[18:58:01] <SWPadnos> EMC can work with any number of I/O cards (simultaneously)
[18:58:11] <SWPadnos> the parallel port gives you 13 pins usually
[18:58:11] <crepincdotcom> can i get a ppt io card?
[18:58:16] <SWPadnos> 8 out and 5 in
[18:58:23] <Guest299> yep
[18:58:23] <crepincdotcom> SWPadnos: which 5 are in?
[18:58:33] <SWPadnos> yes, you can have multiple parports
[18:58:37] <Guest299> 10,11,12,13 and 15
[18:58:40] <SWPadnos> http://www.byterunner.com is oe option
[18:58:44] <SWPadnos> one
[18:59:13] <crepincdotcom> hm
[18:59:21] <SWPadnos> if you "loadrt hal_parport" then "show pin parport", you'll see a list of all parport pins
[18:59:31] <SWPadnos> ones that end in "-in" or "-in-not" are input pins
[18:59:31] <Guest299> cnc4pc has a breakout board for 25 bucks that can toggle input and outputs
[18:59:50] <crepincdotcom> SWPadnos: how do i run the hal commands, do i just run hal first?
[18:59:56] <Guest299> its what im using
[19:00:30] <SWPadnos> crepincdotcom, the easiest way (assuming that emc2 is installed, not run-in-place), is to run emc from the menu
[19:00:36] <SWPadnos> select a stepper config
[19:00:41] <crepincdotcom> right
[19:00:47] <SWPadnos> then open a terminal and use halcmd
[19:00:50] <Guest299> plan on getting a real motion card later
[19:00:52] <crepincdotcom> ah ok
[19:00:54] <SWPadnos> halcmd show pin parport
[19:00:56] <crepincdotcom> k
[19:02:01] <SWPadnos> Guest299, just for fun, here's a list of a bunch of HAL components (I'm not sure it's exhaustive): http://cvs.linuxcnc.org/cvs/emc2/src/hal/components/
[19:02:54] <crepincdotcom> these geckos are $140 and each one only drives one motor!
[19:02:54] <crepincdotcom> gah
[19:03:04] <SWPadnos> yes
[19:03:11] <crepincdotcom> *cry*
[19:03:16] <SWPadnos> $114 for the ones without pulse multiplier
[19:03:22] <crepincdotcom> sigh
[19:03:56] <SWPadnos> though the 203v (at $147) is better in many ways - it's basically unkillable
[19:04:15] <crepincdotcom> im not gonna have $300+ to throw down anytime soon
[19:04:22] <lerneaen_hydra> *coughanonimasucough*
[19:04:30] <SWPadnos> I know the problem :)
[19:04:33] <crepincdotcom> huh?
[19:04:33] <lerneaen_hydra> crepincdotcom; got lots of free time?
[19:04:38] <crepincdotcom> lerneaen_hydra: a good bit
[19:04:51] <lerneaen_hydra> crepincdotcom; you could make your own
[19:04:59] <Guest299> yep the 203v is the better stepper drive
[19:05:00] <crepincdotcom> thats what iv been doing, but everyone is telling me to bye one
[19:05:03] <lerneaen_hydra> especially if you don't need microstepping
[19:05:06] <crepincdotcom> i dont
[19:05:08] <SWPadnos> crepincdotcom, you had mentioned your smotor voltage current before - what are they again?
[19:05:12] <Guest299> thanks i saved that link
[19:05:16] <SWPadnos> argh
[19:05:37] <SWPadnos> Guest299, that's not the ideal place to look for information, but it will always be up to date (since that's the source :) )
[19:05:49] <Guest299> cool
[19:05:51] <crepincdotcom> SWPadnos: i have 3 steppers curently on the mill that came out of canon scanners. i think theyre like 5v 3 amp. i have a box of other unmatched motors of varying sorts
[19:06:14] <SWPadnos> did you read the step motor basics paper from Geckodrive?
[19:06:18] <crepincdotcom> yes
[19:06:25] <SWPadnos> cool - lots of good info there
[19:06:27] <crepincdotcom> definatly some things i didnt know
[19:06:55] <crepincdotcom> i learned that im killing my motors..... when i have an axis stopped, the coil just sits energized, but I dont have current limiteing on it so its like aahhhhhhhhh
[19:06:58] <crepincdotcom> which is why it gets so hot
[19:07:08] <Guest299> i gotta run for a bit,thanks for the help
[19:07:10] <SWPadnos> I don't know any specifics of the L297, but there are several drivers that use it, including some kits
[19:07:13] <SWPadnos> see you later
[19:07:17] <Guest299> greatly appreciated
[19:07:23] <SWPadnos> one Q before you go
[19:07:27] <Guest299> k
[19:07:29] <SWPadnos> which config did you start with?
[19:07:41] <SWPadnos> stepper/inch.ini?
[19:07:42] <Guest299> stepper_inch
[19:07:44] <SWPadnos> ok
[19:08:11] <Guest299> in gonna remove the stuff i dont need now that its working
[19:08:16] <SWPadnos> ok.
[19:08:23] <Guest299> one more quick question
[19:08:25] <SWPadnos> I see that the config has a comment section on shared home switches
[19:08:47] <SWPadnos> but not shared home and limit for all axes, I guess
[19:09:02] <SWPadnos> shoot
[19:09:14] <Guest299> can emc output a 12.5 khz squarewave signal to an output pin
[19:09:40] <Guest299> so that a charge pump could used
[19:09:59] <SWPadnos> see the chargepump component, I think :)
[19:10:04] <SWPadnos> or freqgen
[19:10:39] <SWPadnos> oops - it's called charge_pump
[19:10:46] <Guest299> is that in the hal manual?
[19:10:51] <SWPadnos> I'm not sure
[19:11:20] <SWPadnos> I don't know that there's a full list of components in the manual :(
[19:11:28] <Guest299> i didnt see it,but looked like freqgen could work
[19:11:40] <SWPadnos> you can find out some of this stuff if you get comfortable with the halcmd "shell"
[19:12:25] <SWPadnos> halcmd has tab completion, so you can open a halcmd shell ( halcmd -kf ), and type loadrt <tab><tab> to get a list of all realtime components that can be loaded
[19:12:30] <Guest299> cool,i got a lot to learn for sure,but im moving and homing for the first time ever
[19:12:41] <SWPadnos> that's a good start
[19:13:01] <Guest299> for sure
[19:13:29] <Guest299> thanks again
[19:13:37] <SWPadnos> you're welcome
[19:13:54] <Guest299> gotta go figure out how to updat the java on my ubuntu box
[19:14:12] <SWPadnos> see #ubuntu :)
[19:14:16] <Guest299> so i dont have to run back and forth
[19:14:34] <SWPadnos> why not just use an IRC client instead of the web client?
[19:14:44] <SWPadnos> like chatzilla in firefox ...
[19:14:45] <Guest299> i downloaded the rpm,just gotta get it to install
[19:15:12] <Guest299> havent tried that yet,does it come here
[19:15:45] <SWPadnos> firefox is installed by default, and to install chatzilla, all you need to do is go to help -> extensions, then get more extensions
[19:15:50] <SWPadnos> search for chatzilla and install it
[19:16:04] <SWPadnos> I use it on both Windows and Linux, and it works greaet
[19:16:06] <SWPadnos> great,too
[19:16:49] <Guest299> coll,will try that instead
[19:16:52] <Guest299> cool
[19:17:21] <Guest299> tahnks again
[19:17:25] <Guest299> thanks
[19:17:31] <SWPadnos> enjoy :)
[20:09:03] <alex_joni> hi all
[21:05:04] <SWPadnos> oh man, this is too funny: http://www.youtube.com/watch?v=KyLqUf4cdwc&eurl=
[21:05:12] <SWPadnos> you need audio though
[21:05:28] <Jymmmm> too bad it's youtube...
[21:05:36] <Jymmmm> * Jymmmm no watch youtube
[21:05:46] <SWPadnos> what, HE isn't YouTube enabled? ;)
[21:06:04] <SWPadnos> what good is that fat pipe then, anyway
[21:06:16] <Jymmmm> No, I just HATE YouTube.... worse than BDTV
[21:06:29] <SWPadnos> watch this one - it's very funny
[21:06:42] <Jymmmm> Since YOU asked, ok....
[21:06:46] <SWPadnos> and it's even work safe (as long as the occasional swear word won't get you fired)
[21:06:53] <Jymmmm> I avoifd ALL of Alex's links
[21:07:18] <SWPadnos> heh
[21:07:36] <SWPadnos> this is a sample of writinga simple perl script using Windows Vista speech recognition
[21:08:02] <Jymmmm> watching.... Press Caps lock
[21:18:12] <Jymmmm> SWPadnos: Ok, funny, but way too long.
[21:18:22] <SWPadnos> yeah - I think that was the point :)
[21:18:38] <Jymmmm> No more youtube links from you either!
[21:18:49] <SWPadnos> the recognition actually seemed to work well, but the interpretation was very lacking
[21:18:54] <SWPadnos> :P
[21:19:21] <Jymmmm> Setup for dictation, not programming it seems
[21:19:34] <skunkworks> funny
[21:19:54] <skunkworks> Jymmmm: that websit seems to be working today.
[21:19:58] <SWPadnos> yeah - I'm not sure how this software works. I know that Dragon Dictate sepcifically had separate command and dictation modes
[21:20:27] <SWPadnos> Vista may also, but I suspect thay decided that would be too complicated
[21:20:33] <SWPadnos> they
[21:34:57] <anonimasu> lol
[21:36:44] <anonimasu> it's hillarious
[21:45:38] <alex_joni> http://www.youtube.com/watch?v=bWhtkkOYoxo&NR <- that's hillarious
[21:46:08] <Jymmmm> * Jymmmm sez, JUST SAY NO TO alex_joni's YouTube links!
[21:49:23] <alex_joni> Jymmmm: you don't know what you're missing :P
[21:49:33] <anonimasu> alex_joni: heh
[21:49:40] <anonimasu> alex_joni: are you making diamonds?
[21:49:51] <Jymmmm> alex_joni If it's your link, I'm not worried about it =)
[21:49:59] <alex_joni> well.. not really, but Jymmmm surely isn't :P
[21:51:45] <anonimasu> alex_joni:
[21:51:47] <anonimasu> what the **, my microwave broke, my house burned down, and i do NOT have any diamonds, just some solid.. thank you guys. Please, this is scam
[21:52:21] <anonimasu> how retarded
[21:52:24] <Jymmmm> Already heard about it, not missing a thing alex_joni
[21:53:29] <alex_joni> anonimasu: loool
[23:49:14] <ejholmgren> moo
[23:51:09] <Jymmmm> Quawk
[23:52:30] <jlmjvm> anyone know how to install the axis gdepth download?
