[01:41:06] <tom2> tom2 is now known as tom3p
[11:16:33] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[11:20:06] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[12:35:43] <jthornton> when using M1nn and you set a paraport pin can you wait for another pin somehow before the exit?
[12:36:32] <SWPadnos> there's probably some bash while-loop foo you could do
[12:36:46] <jthornton> thanks I'll look that up
[12:37:44] <SWPadnos> you'd probably need to use halcmd -s to return just the value of whatever you want to wait for
[12:38:01] <jthornton> ok
[12:38:07] <SWPadnos> something like fred=`halcmd -s show pin <whichever>`
[12:38:47] <jthornton> thanks
[12:38:49] <SWPadnos> sure
[12:44:06] <alex_joni> otoh, if the pin doesn't change you're stuck in M1xx forever
[12:48:27] <jthornton> yea, I was just wondering about that forever while loop
[12:48:39] <SWPadnos> details
[12:49:06] <jthornton> maybe M66 with a timeout would be better
[12:50:04] <SWPadnos> you can do "or" conditions in bash loops
[12:50:21] <SWPadnos> so you can have a counter or check the time, and also look at the pin
[12:50:34] <jthornton> or have a bailout button
[13:04:47] <cradek> jthornton: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?CustomMcodesToHal
[13:06:20] <jthornton> cradek: cool
[13:16:47] <steves_logging> steves_logging is now known as steve_stallings
[13:17:40] <steve_stallings> cradek - congrats on you new mill, guess the pressure is off for the Boss-8 transition board 8-)
[13:23:08] <cradek> oh was the pressure on previously? haha
[13:25:36] <steve_stallings> not that you could tell from the results....
[13:26:01] <steve_stallings> pressure now is to get the boards I was showing at the Fest released
[13:26:57] <cradek> were those the use-magic-to-get-more-IO boards?
[13:27:50] <steve_stallings> it has been one hell of a summer, my dad passed away in June, my sister's teenage twin boys spent a couple of weeks visiting as summer vacation, and my main programmer/engineer's mother is in and out of the hospital
[13:28:36] <steve_stallings> yes the more I/O board, and several accessory boards
[13:29:02] <cradek> sorry to hear that. the boys must have been a fright if you put them in the same sentence as the other bad news.
[13:29:45] <steve_stallings> great guys actually, but way too much energy and activity for a old fart used to living alone
[13:31:16] <steve_stallings> plus the six 800 mile round trips to home in NC to settle estate and ferry the boys back and forth
[13:32:49] <cradek> yuck. hope everything is back to normal now.
[13:33:34] <steve_stallings> getting there, I am putting the finishing touches on revision B of the PMDX-125 circuit board, planning to send out for fab on Monday
[13:34:23] <steve_stallings> because I jumped the gun and listed it on our web site, we get emails daily asking when it can be purchased
[13:34:33] <cradek> oops!
[13:36:01] <cradek> I think early announcements might sometimes be a winning strategy, but you can't do it too much or you get labeled as a vaporware vendor
[13:36:29] <steve_stallings> and it slows down sales of older similar products in the mean time
[13:37:01] <cradek> ah, I bet
[13:37:25] <cradek> bbl
[17:32:06] <holy_> What if I have compiled emc2-sim and try to copy it to the same system, and all dependencies in both source and destination systems are installed by use of the offline debian files?
[17:33:30] <holy_> Will it normally be the same program? (And Home directory is the same.)
[17:34:55] <jthornton> Yea, we had an erection this morning... the tower is now vertical and one with the rocks up on the hill
[17:35:35] <holy_> erection? Mrs 3G is happy...
[17:35:41] <holy_> ;)
[17:35:49] <micges> holy_: should work, try it
[17:35:55] <holy_> OK
[17:36:45] <holy_> Why couldn't I copy ~/emc2-compiled-as-sim to FAT32 partition? Any "strange" filenames?
[17:37:22] <micges> holy_: copy to fat32 wouldn't work
[17:37:46] <jthornton> 256k wireless internet connection
[17:38:09] <jthornton> up to 1Mb
[17:38:18] <holy_> even copy to another username wouldn't work
[17:38:36] <holy_> jthornton: you can listen to online radio now.
[17:40:02] <jthornton> :)
[17:40:39] <jthornton> you mean I don't have to roll the gold wing out of the garage and sit in the driveway to listen to music anymore...
[17:40:49] <alex_joni> jthornton: working already?
[17:41:14] <jthornton> no, just got it raised up this morning
[17:41:57] <alex_joni> ah, ok .. soon then
[17:41:59] <jthornton> I'll call them as soon as I can find my box of cat5e
[17:42:26] <jthornton> :)
[17:44:22] <holy_> jthornton: you have honda gold wing?
[17:44:33] <holy_> does it have a rear gear?
[17:44:54] <holy_> I want to add rear gear to my Ural
[17:45:23] <jthornton> yes
[17:45:29] <holy_> wow
[17:48:07] <jthornton> my first was a Honda 50 Super Sport in 1968... worked my way up from that
[17:49:13] <jthornton> http://i47.photobucket.com/albums/f163/johnplctech/HPIM1988.jpg
[17:51:03] <jthornton> http://www.vaiden.net/honda_ss50-67.jpg
[17:52:00] <holy_> so, you're old...
[17:52:09] <jthornton> LOL
[17:52:36] <holy_> My Ural isn't registered yet. First time I used it, police have catched me...
[17:53:19] <jthornton> you have a side car?
[17:53:58] <holy_> it's carburetors has a channel for air. I didn't know about this channel, and the engine have stopped -- I rode thru dirt.
[17:55:15] <holy_> I will cheat and register it as a single motorbike. I'll tell the sidecar was damaged, and ask for a new technician passport for the vehicle.
[17:55:44] <holy_> I used it with a sidecar in snow at the territory nearby my garage.
[17:58:24] <holy_> I used it with asphalt tyres in dirt few times. In hills. It was hard to get back to the road.
[17:58:41] <jthornton> I used to ride the Honda 50 on ice and snow in Alaska
[17:59:00] <jthornton> used knobby tires with screws sticking out and took the front fender off
[17:59:46] <holy_> I only like trophies and hauls. Don't even plan to buy angry tyres.
[18:02:39] <holy_> I actually rife Norco Mountaineer in warm winter days, but its V-brake brakes (the model is old) works as "digital".
[18:05:43] <frallzor> * frallzor allmost cries out of happinies
[18:05:56] <frallzor> *happieness even
[18:06:44] <holy_> I think there could be some clubs somewhere around, and folks would agree to visit Europe.
[18:07:09] <holy_> frallzor: Have you become a father of a... son?
[18:07:17] <frallzor> well allmost
[18:07:27] <frallzor> diy-mill, kind of like a son i guess
[18:07:29] <frallzor> just better
[18:07:58] <holy_> "diy"?
[18:08:04] <frallzor> do it yourself =)
[18:08:20] <holy_> :)
[18:08:32] <frallzor> allmost done with my first build
[18:08:49] <skunkworks_> frallzor: pictures?
[18:08:58] <holy_> "do-it-yourself" as it runs when you cycle something ;)?
[18:09:20] <frallzor> as in building it myself :P
[18:09:36] <holy_> I meant pedals, "pedal-powered mill".
[18:09:40] <holy_> =-O
[18:09:46] <celeron55> that would be cool 8)
[18:09:53] <frallzor> nah :P
[18:10:00] <frallzor> diy-cnc-mill!
[18:10:05] <frallzor> no more funnystuff!
[18:10:08] <frallzor> :P
[18:11:36] <holy_> frallzor: tell us more!
[18:11:59] <frallzor> now I just need a few screws and a small piece of metal =)
[18:13:36] <holy_> frallzor: have you gathered components from manufacturers, or you are capable to create circuit boards?
[18:15:13] <frallzor> yes to both
[18:15:25] <frallzor> but I just bought a gecko 540
[18:15:45] <frallzor> didnt want thr hassle with making one myself
[18:16:31] <holy_> frallzor: How do you know how to build circuit boards? I think I will never be able to do it! Or at least when my future wife will do all home work.
[18:17:15] <holy_> frallzor: can you give a link to the pdf with gecko 540?
[18:17:19] <frallzor> well most applications are well documented so when asking around you remember a thing or two
[18:17:50] <frallzor> http://www.geckodrive.com/
[18:17:58] <frallzor> look there for pdf =)
[18:18:10] <holy_> Anyway, I do not even understand why Multimeter has so many features...
[18:18:40] <holy_> frallzor: this web-browser has no plugin for viewing main page.
[18:20:26] <Jymm> Gecko sale ends today!
[18:20:56] <alex_joni> what sale?
[18:21:18] <Jymm> alex_joni: 100pc pricing
[18:21:28] <Jymm> annual customer appreciation sale
[18:21:47] <frallzor> http://www.geckodrive.com/upload/G540%20REV3%20MANUAL.pdf g540 manual holy_
[18:21:59] <Jymm> alex_joni: It's been in the topic since August 7th =)
[18:22:00] <jthornton> but I only need 99 pcs
[18:22:16] <holy_> frallzor: thanks! (My mom pays for Internet access.)
[18:22:17] <Jymm> jthornton: 100pc pricing, qty 1
[18:23:30] <alex_joni> hmm.. the G320x is nice
[18:24:44] <frallzor> there is a nice other brand too for servos
[18:24:56] <frallzor> granite
[18:25:06] <alex_joni> the G251 for 49$ is also quite interesting
[18:26:15] <Jymm> frallzor: Geco isn't the only player, but for those that have been able to afford them, I've mentioned their annual sale.
[18:26:21] <Jymm> haven't
[18:26:49] <frallzor> well yeah thats true
[18:27:22] <jthornton> * jthornton heads up for a nap :)
[18:27:54] <Jymm> alex_joni: Well, time to restock the shelves!
[18:31:21] <alex_joni> http://www.granitedevices.fi/index.php?q=vsd-e-breakout
[18:32:34] <Jymm> alex_joni: Sigh... USB powered
[18:34:11] <Jymm> alex_joni: All these so-called "breakout boards" all seem to be a POS when you take a close look.
[18:37:45] <alex_joni> http://www.granitedevices.fi/index.php?q=servo-drive-vsd-e
[18:37:49] <alex_joni> that one is interesting
[18:38:04] <alex_joni> works with brushed DC, brushless DC, AC, and steppers
[18:41:44] <Jymm> alex_joni: Shit man, I can do that with a bnch of resistors =)
[18:45:29] <alex_joni> I'm sure you can
[18:45:54] <Jymm> oh, and 14 popsicle sticks.
[18:52:26] <Jymm> Do people still use the term blueprints?
[18:53:49] <alex_joni> launchpad does ;)
[18:54:23] <Jymm> I haven't heard the term used in years, except in construction.
[18:54:45] <alex_joni> https://blueprints.launchpad.net/
[18:55:10] <Jymm> Well "blueprint" in the outline aspects, not the unroll on the table sorta way.
[19:13:40] <eric_unterhause1> I remember having a blueprint made back in the day, it was fun and pretty cheap
[19:17:57] <Jymm> Yeah, "back in the day". Just haven't hear the term used lately except in construction trade.
[19:18:34] <jthornton> I can even remember when they were actually blue
[19:18:58] <jthornton> and smelled like ammonia
[19:18:59] <Jymm> jthornton: shhhh, your age is showing again.
[19:19:18] <Jymm> * Jymm hands jthornton a walker
[19:19:47] <jthornton> it's hard to put a walker in the trunk of the gold wing
[19:20:13] <Jymm> Then it be called training wheels
[19:20:35] <Jymm> Hey, I knew a 78yo Lady that road cross country on a 750
[19:20:52] <Jymm> in all weather too
[19:20:57] <jthornton> when I need more than two wheels I'll get a convertable
[19:21:31] <Jymm> They just never let her ride alone, always in a group.
[19:22:33] <jthornton> might get lost alone
[19:22:46] <jthornton> or forget where you wanted to go
[19:22:51] <Jymm> No, mostly for breakdowns and such
[19:23:22] <Jymm> She could ride, but couldn't pick up the bke if tipped over.
[19:23:33] <jthornton> * jthornton needs to go check the smoker brb
[20:14:42] <holy_> Which file does the program takes translation from?
[20:17:45] <dmess> High all....
[20:19:56] <holy_> hi
[20:46:02] <jthornton> .po files
[20:55:54] <alex_joni> jthornton: ?
[20:58:45] <holy> anyway, the "Quick help" in Russian is even wider than 1200x800 screen. "Language=en emc ... .ini" is better.
[21:03:20] <numen> hello
[21:09:52] <jthornton> alex_joni: ?
[21:10:10] <jthornton> bjt
[21:49:29] <alex_joni> good night all
[23:05:16] <frallzor> is there some option in emc to make the mill go back to 0 0 0?
[23:05:24] <frallzor> and not just reset the values
[23:05:44] <frallzor> return to home or something
[23:09:54] <skunkworks> g53x0y0z0?
[23:09:55] <fenn> g53 x0 y0 xz0 ?
[23:10:00] <fenn> damn he beat me
[23:10:03] <skunkworks> heh
[23:10:18] <frallzor> without that =) I dont do code manually :P
[23:10:23] <fenn> oh boo hoo
[23:10:26] <frallzor> no button or something
[23:10:27] <frallzor> ?
[23:10:30] <fenn> it's not a lollypop button
[23:10:30] <frallzor> "home"
[23:10:34] <skunkworks> fenn - what do you think about using automotive tie rod ends for cheap actuator ends..?
[23:11:02] <fenn> skunkworks: the thing i showed the other day was a tie-rod ball joint
[23:11:38] <skunkworks> really? I thought you were talking about universal joints.
[23:11:47] <fenn> er. i was talking about those too
[23:12:06] <skunkworks> I missed that :)
[23:12:42] <fenn> http://fennetic.net/irc/ball-joint.jpg
[23:12:52] <fenn> found it on some jeep website
[23:13:03] <fenn> mostly i was thinking "how do i make these myself"
[23:14:12] <fenn> the cardan (universal) joint has much greater range of motion though
[23:14:42] <skunkworks> yes
[23:14:56] <skunkworks> emc's kins would have to be re-written?
[23:15:04] <skunkworks> for a cardan joint?
[23:15:14] <fenn> not if the two cylinders were co-planar
[23:15:30] <fenn> so you'd have a spider like in a CV joint
[23:15:32] <skunkworks> ok - (that is how I would make them.)
[23:15:45] <fenn> ... a thing that holds 4 cylinders 90 degrees apart
[23:16:22] <fenn> also there's the minor problem of twist about the screw changing the length of the screw
[23:16:50] <fenn> the NIST hexapod had laser interferometers on each leg so it didnt matter what the screw was doing
[23:17:00] <skunkworks> * skunkworks bought a 16gb keychain drive today on a whim.
[23:17:18] <fenn> almost feels like the future doesn't it
[23:17:46] <skunkworks> almost.
[23:18:12] <skunkworks> twist about the screw>
[23:18:14] <skunkworks> ?
[23:18:38] <fenn> when you rotate a nut on a screw it translates, right?
[23:18:48] <fenn> ok so what happens when you rotate the platform around the Z axis?
[23:19:21] <fenn> all the struts twist to accomodate that rotation because the rotational bearing around the strut axis is the nut
[23:20:00] <fenn> so the strut length is off by some fraction of a rotation's worth
[23:20:51] <fenn> unless your encoder is on the other end of the strut
[23:21:04] <skunkworks> did you see this? http://www.youtube.com/watch?v=7TowJZQi-qY&feature=channel
[23:21:12] <fenn> i was assuming the encoder would be down by the motor
[23:22:35] <fenn> wow what a cheezy intro
[23:22:55] <skunkworks> :)
[23:26:37] <skunkworks> that would pretty negligable - wouldn't it?
[23:26:44] <skunkworks> negligable?
[23:26:54] <fenn> depends on the screw pitch and what accuracy you require
[23:28:19] <fenn> why have i never heard of variax?
[23:33:31] <skunkworks> heh - I don't know
