[00:00:32] <tjb1> Would anyone be willing to load test an assembly in solidworks for me?
[00:01:34] <r00t4rd3d> you better wak ReadError
[00:02:17] <tjb1> I really need to learn how to do that...
[00:07:47] <tjb1> Well this calculator says a 64" fixed 2" square with 1/8" wall, 500lb center load will have a deflection of .0417"
[00:08:06] <tjb1> or .0307 with 3/16" wall
[00:10:10] <tjb1> .017" isnt worth the cost
[02:12:14] <DJ9DJ> moin
[04:24:09] <Loetmichel> mornin'
[04:25:55] <Loetmichel> again the mill engraves Slot plates... its time the order is done, i want to have a weekend again :-(
[04:26:49] <archivist> Im going out to play steam engine driving !
[05:31:29] <Diony> hi
[05:32:21] <Diony> Is there a way to do g38.x until probe or machine limits reached?
[06:06:25] <jthornton> yea just make the move long enough
[06:27:15] <Jymmm> jthornton: goin fishing?
[06:28:15] <Diony> jthornton: sure but how to know the "long enough" with offsets (tool, G5x and 92) including rotations.
[06:29:11] <jthornton> make it a million miles long
[06:29:39] <Diony> linuxcnc doesnot allow the move...
[06:30:50] <jthornton> Jymmm, ?
[06:31:09] <Jymmm> jthornton: you up at 6am on a saturday
[06:31:56] <jthornton> yea, slept in for a change
[06:32:06] <Jymmm> oh, heh
[06:32:24] <jthornton> usually up at 5am
[06:32:48] <Jymmm> jthornton: Didn't realize it. usually dont see you till 8ish
[06:33:44] <jthornton> I'm usually reading the forum, banning spammers etc.
[06:34:37] <Jymmm> jthornton: LOL, Hey I need about 2.5" disc punched from 0.024" SS, suggestions?
[06:35:31] <jthornton> you need 1 or 10,000?
[06:35:38] <Jymmm> 50K
[06:35:49] <Jymmm> But, I dont need all that many immediatly
[06:36:54] <Jymmm> jthornton: I can get away with 100+ for now.
[06:38:43] <jthornton> 100 would be kind of expensive to make a die for, stacked and cut on a water jet maybe...
[06:39:11] <Jymmm> jthornton: can a waterjet engrave?
[06:40:32] <jthornton> dunno
[06:40:36] <jthornton> but doubt it
[06:41:08] <Jymmm> jthornton: I sent out RFQ's to a few precision sheet metal place, what they've been quoting so far is really out there.
[06:41:29] <Jymmm> I like the stacked idea though.
[06:42:09] <jthornton> if you don't spec the tolerance correctly the price of an item goes up exponentially
[06:42:45] <Jymmm> Well, I told them I'm really flexible
[06:43:58] <jthornton> flexible is subject to interpretation and shops don't like that
[06:44:05] <Jymmm> ah
[06:44:30] <Jymmm> Well, I think much of the price they gave was due to the laser engraving on SS.
[06:44:45] <jthornton> you have to give them exact tolerance like 2.5" +- 1/8"
[06:45:09] <jthornton> ask them to break out each op in the quote
[06:45:35] <Jymmm> I did ask them to itemize the quote, none of them did
[06:46:19] <Jymmm> Hell, I had oen place decline, and had to put a flame under the asses of two others to even get a quote.
[06:47:58] <jthornton> in that case what you got was "I don't want to do this job but if you pay this much I'll be happy to do it"
[06:48:22] <Jymmm> I'm sure, I'm just nto sure why, it's an easy job.
[06:49:45] <Jymmm> except for the laser engraving
[06:49:49] <jthornton> many things look easy till you try and do them
[06:50:17] <Jymmm> jthornton: can your plasma cut that thin of SS ?
[06:53:32] <jthornton> the thinest listed on the cut chart for ss is 24ga
[06:54:53] <Jymmm> oh, so you can. would it warp?
[06:55:44] <jthornton> I've never tried to cut 24ga, I don't even know how one would touch off much less hold the material still
[06:56:24] <jthornton> I'm guessing you would need some kind of frame to stretch the material to keep it flat
[06:56:26] <Jymmm> ah
[07:02:17] <jthornton> does it have to be laser etched? you can't use a pad printer?
[07:02:42] <Jymmm> jthornton: Text needs to withstand 1200F+
[07:02:52] <jthornton> ah
[07:02:59] <Jymmm> Unless thee is a high temp ink
[07:03:02] <Jymmm> there
[07:03:41] <jthornton> there might be... what does header paint withstand?
[07:03:55] <Jymmm> 600F iirc
[07:04:50] <Jymmm> hmmmm 2000F http://www.autozone.com/autozone/accessories/Rust-Oleum-12-oz-white-high-heat-spray-paint/_/N-261a?itemIdentifier=69499_0_0_
[07:36:50] <r00t4rd3d> Get some VHT, 1500F
[07:37:35] <r00t4rd3d> VHT Flameproof
[07:38:05] <r00t4rd3d> http://www.caswellplating.com/paints-and-coatings/vht-aerosol-paints/vht-flameproof-coatings.html
[07:39:00] <jthornton> ah caswellplating my favorite place
[07:39:36] <r00t4rd3d> really?
[07:39:40] <r00t4rd3d> you in ny?
[07:40:31] <jthornton> no
[07:41:26] <jthornton> I got a powder coating rig from them and I have acquired 90% of an anodizing kit that needs to get set up
[07:43:00] <jthornton> so Jymmm if you want to send me some material I can test cut a couple for you
[07:44:18] <Jymmm> jthornton: Thanks. Might be later this month as I'm working between two projects
[07:53:28] <andypugh> Jymmm: How does mah unban himelf?
[07:53:44] <jthornton> he can't an operator has to do that
[07:53:46] <r00t4rd3d> irc?
[07:53:48] <Jymmm> andypugh: ask?
[07:54:04] <jthornton> I've tried from here
[07:54:13] <andypugh> How does he ask if he is banned?
[07:54:29] <jthornton> lol
[07:54:34] <Jymmm> andypugh: I PM'ed him to change his nick, join the channel, and just ask
[07:54:43] <Jymmm> last night that is
[07:55:10] <jthornton> I tried to unban him but it said I must be the channel operator and that looks like cradek
[07:55:21] <r00t4rd3d> jymm set it
[07:55:25] <Jymmm> is he here?
[07:55:59] <andypugh> Anyway, he emailed me to say the problem was fixed. But that he can't figure out how to get unbanned
[07:56:13] <r00t4rd3d> /mode -b mhaberler*!*@*
[07:56:21] <Jymmm> *sigh* another case of can't RTFM
[07:56:25] <Jymmm> lol
[07:56:39] <andypugh> Where is TFM for IRC?
[07:57:26] <r00t4rd3d> that is so scary
[07:57:30] <jthornton> LOL
[07:58:05] <r00t4rd3d> was cradek drunk when he set that?
[07:59:26] * r00t4rd3d sets mode +b mhaberler*!*@*
[08:06:48] <andypugh> wb mah
[08:08:33] <jthornton> andypugh, did you ever run a BLDC from the arduino?
[08:08:58] <andypugh> Yes.
[08:10:04] <andypugh> Well, I ran a resolver-feedback AC servo from an Arduino. A conventional BLDC would probably be easier.
[08:10:53] <jthornton> hmm so you need some kind of switch to power the windings and read the position with the hall inputs?
[08:11:41] <andypugh> However, I seem to recall some problem with the Arduino not dong phase-locked three-phase PWM easily, so I ended up using a single PWM output gating a buffer chip.
[08:12:06] <andypugh> Yes, if you have halls it is all rather simple.
[08:12:36] <jthornton> I imagine simple once you know how :)
[08:13:16] * jthornton searching for some info on the web but not really finding much
[08:14:23] <andypugh> If you have the right hall pattern decoding no phases ever go straight from high to low-side drive, so you don't actually have to take precautions about shoot-through. Though the Arduino PWMs allow you to set up two thresholds on the same counter so that you can cover for it anyway.
[08:15:32] <jthornton> just found a graph of the hall output and I can see that only one hall changes at a time
[08:17:00] <jthornton> ah found a Microchip AN885 Brushless DC Motor Fundamentals pdf
[08:21:19] <r00t4rd3d> http://www.pololu.com/catalog/product/1352
[08:21:31] <r00t4rd3d> i have one of those, what should i do with it
[08:24:33] <andypugh> Control some "servos" perhaps? I am pretty sure that it refers to radio control plane "servos" thhough.
[08:26:43] <r00t4rd3d> yeah it is
[08:26:50] <r00t4rd3d> i have one, just sits though
[08:33:23] <r00t4rd3d> http://www.thingiverse.com/thing:2433
[08:33:36] <r00t4rd3d> robotic arm it is!
[08:40:25] <Tom_itx> i'd imagine an xmega would do the bldc alot easier since it has alot more complex timer stuff available
[08:41:13] <Tom_itx> jthornton is it 3 phase?
[08:44:29] <Tom_itx> http://www.atmel.com/Images/doc8012.pdf
[08:44:46] <Tom_itx> source is also there
[08:46:21] <Tom_itx> http://www.atmel.com/applications/automotive/motor_control_systems/default.aspx?tab=documents
[08:46:27] <Tom_itx> rest of the articles in the search
[08:47:27] <jthornton> Tom_itx, thanks, and yes I assume 3 phase
[08:47:45] <jthornton> I have one with a built in drive but I need more than it can provide
[08:47:50] <Tom_itx> http://www.atmel.com/Images/doc8311.pdf
[08:47:55] <Tom_itx> there's one for the xmega series
[08:48:07] <Tom_itx> it would be more robust probably
[08:48:15] <Tom_itx> but they're 3.3v chips
[08:48:26] <jthornton> what does that mean?
[08:48:39] <Tom_itx> it means you run them at 3.3v not 5
[08:49:09] <Tom_itx> non tolerant i believe, they may be 5v tolerant on the io... i don't know enough about them yet
[08:50:08] <Tom_itx> they're alot more complex than the regular 8bit avrs
[08:50:52] <jthornton> this is what I have atm http://www.anaheimautomation.com/products/brushless/brushless-integrated-item.php?sID=147&pt=i&tID=97&cID=48
[08:51:25] <Tom_itx> the old motorola 68332 had built in microcode to control them
[08:51:40] <Tom_itx> as well as quadrature read
[08:52:55] <Tom_itx> seems it has it's own controller
[08:53:47] <Tom_itx> An external potentiometer (10K) or external voltage (0-5VDC) can be used to control the speed
[08:54:25] <Tom_itx> the xmega have dac out i believe
[08:54:44] <Tom_itx> so you read the hall feedback and spit out dac to the control on the motor
[08:55:55] <Tom_itx> jthornton is this your standalone project?
[09:02:39] <Tom_itx> jthornton i don't think you have to do the comutations on that one
[09:03:45] <Tom_itx> you need something to read the hall sensor int0 or pcint will do then output a 0-5v range for velocity mode control
[09:04:28] <Tom_itx> with another pin for direction
[09:07:19] <jthornton> Tom_itx, yes this is for my stand alone project
[09:07:48] <jthornton> this is what I think I want to use actually now http://www.anaheimautomation.com/products/brushless/brushless-gearmotor-item.php?sID=156&pt=i&tID=98&cID=47
[09:09:20] <Tom_itx> star wound 3 phase
[09:09:34] <jthornton> that good or bad?
[09:09:58] <Tom_itx> i don't know
[09:10:55] <Tom_itx> you may have to do your own comutation with that one
[09:11:01] <Tom_itx> i can't tell from that page
[09:12:03] <jthornton> says on this one winding type: Delta, 4 poles
[09:12:49] <Tom_itx> which one?
[09:12:52] <Tom_itx> the link?
[09:12:54] <Tom_itx> These star wound motors come with integrated hall sensors for closed loop control for velocity applications
[09:13:07] <Tom_itx> they're confused
[09:13:12] <jthornton> http://www.anaheimautomation.com/products/brushless/brushless-gearmotor-item.php?sID=158&pt=i&tID=98&cID=47
[09:13:25] <jthornton> I stay confused
[09:14:31] <Tom_itx> it doesn't have the built in controller like the first one
[09:14:51] <jthornton> no, these are just BLDC motors with gear boxes attached
[09:15:11] <Tom_itx> so you would have to do your own BLDC function and feedback
[09:15:24] <jthornton> yea
[09:15:35] <jthornton> I guess it is time to learn how to do that
[09:15:54] <JessicaRN> anyone know of a good router speeds n feeds reference?
[09:15:57] <Tom_itx> the xmega are more complex but probably better suited to do that
[09:18:12] <jthornton> like the AVR1607?
[09:18:32] <Tom_itx> http://www.custompartnet.com/calculator/milling-speed-and-feed
[09:18:34] <Tom_itx> http://www.daycounter.com/Calculators/GCode/Feed-Rate-Calculator.phtml
[09:18:42] <Tom_itx> jess ^^
[09:18:48] <JessicaRN> ty tom
[09:19:21] <Tom_itx> jthornton i closed all those pages
[09:19:33] <jthornton> or for $30 just get this http://www.anaheimautomation.com/products/brushless/brushless-driver-controller-item.php?sID=350&serID=15&pt=i&tID=999&cID=23
[09:20:19] <Tom_itx> 2A max
[09:20:23] <Tom_itx> is that enough?
[09:20:29] <Tom_itx> err 3 max
[09:20:31] <jthornton> they have other models
[09:20:50] <Tom_itx> depends how cheap you are :)
[09:21:04] <Tom_itx> the avr will do it but you have to write your own
[09:21:14] <jthornton> depends on how much torque I need for the application really
[09:21:26] <Tom_itx> i have quadrature for one already
[09:21:30] <Tom_itx> using pcint
[09:22:04] <JessicaRN> you all talking about using a avr as a stepper driver? (sorry... came in the middle)
[09:22:15] <Tom_itx> no, a BLDC motor controller
[09:22:21] <Tom_itx> brushless dc
[09:22:25] <Tom_itx> 3 phase
[09:22:26] <JessicaRN> yea
[09:22:28] <JessicaRN> ok
[09:23:38] <JessicaRN> the only thing i know about bldc is a few cool articles put out by mit. these were all focused on EV's and not machining.
[09:25:04] <JessicaRN> Tom_itx: all the cut rate tables I can find are focused on metal. are there any for wood?
[09:27:37] <Tom_itx> http://forum.thecncforum.com/CNC_Woodworking/Feed_rates_IPM
[09:27:39] <Tom_itx> not really
[09:28:57] <JessicaRN> all good. a bunch of this is just trial and error based on the machine and motors, eh?
[09:29:12] <Tom_itx> http://www.onsrud.com/plusdocs/Doc/index.html?model.code=FeedSpeeds
[09:30:34] <JessicaRN> that last one seems nice
[09:30:37] <JessicaRN> ty again
[09:30:45] <Tom_itx> all sorts of wood tables there
[09:32:55] <JessicaRN> sheesh... you know, it's less effort to calculate medication dosages!
[09:33:07] <JessicaRN> that's scary...
[09:33:22] <Tom_itx> chip load * flutes * rpm
[09:33:26] <Tom_itx> = ipm
[09:33:31] <JessicaRN> yeah
[09:34:11] <jthornton> material, moisture level, machine ... the list of variables goes on and on
[09:34:33] <Tom_itx> JessicaRN, you can still plug those numbers in those other calculators
[09:34:51] <JessicaRN> errr... that's all the stuff you learn with experience, right jthornton?
[09:35:41] <jthornton> yea, when you don't get what you expect you just got some experience
[09:35:45] <Tom_itx> some machines would shake apart under some chiploads while others would beg for more
[09:36:12] <r00t4rd3d> i got a large chipload right now
[09:36:20] <r00t4rd3d> bag of doritos
[09:36:33] <Tom_itx> you got a large load of something
[09:36:45] <jthornton> lol
[09:37:26] <JessicaRN> r00t4rd3d: too much of that chipload and you'll be hauling another load... your ass!
[09:37:55] <r00t4rd3d> nope
[09:38:03] <r00t4rd3d> way too active
[09:38:13] <r00t4rd3d> same weight for 20 years
[09:38:25] <JessicaRN> good job
[09:42:05] <r00t4rd3d> i was jk any way. Never would i eat doritos at my computer
[09:42:24] <JessicaRN> jk?
[09:43:03] <r00t4rd3d> just kidding
[09:43:22] <r00t4rd3d> https://images.nonexiste.net/popular/tag/cheetos/
[09:43:25] <JessicaRN> duh
[09:43:35] <r00t4rd3d> funny thats what i was thinking too!
[09:43:45] <r00t4rd3d> :D
[09:43:52] <JessicaRN> i was thinking you were talking a sport... like JV or something...
[09:44:13] <r00t4rd3d> schooling was never my thing
[09:44:58] <r00t4rd3d> my school sport was seeing how much school I could avoid.
[09:45:17] <r00t4rd3d> i was team captain
[09:47:54] <JessicaRN> well, i won't go there except to say that being a dyslexic genius girl who was into computers and electronics never made my school years a lot of fun.
[09:48:42] <r00t4rd3d> dyslexic genius huh?
[09:48:45] <JessicaRN> i know why jeri ellsworth dropped out
[09:49:00] <JessicaRN> yeah, i prayed to dog every night for a cure.
[09:50:41] <r00t4rd3d> the bounty hunter?
[09:51:09] <JessicaRN> you serious? jeri is like every geek girl's idol...
[09:51:33] <JessicaRN> oh
[09:51:35] <JessicaRN> duh
[09:51:36] <r00t4rd3d> lol
[09:51:44] <r00t4rd3d> are you blond also?
[09:51:54] <JessicaRN> <- doesn't have TV...
[09:52:04] <r00t4rd3d> well i dont watch tv either
[09:52:19] <r00t4rd3d> but i know who dog the bounty hunter is for some odd reason
[09:52:38] <r00t4rd3d> probably his idiot status
[09:52:44] <JessicaRN> shows like that are most of the reason i don't have tv
[09:52:50] <JessicaRN> afk.
[09:54:29] <JessicaRN> i'm doing rapid transit repeatability tests and i thought i heard the machine screaming out in the garage
[09:56:03] <JessicaRN> ok, i'm getting off of here and going to cut some wood. thanks for the snf info
[09:56:19] <Tom_itx> ok, i've been asked about feedrate calcs numerous times here so i added those links to one of my pages: http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
[10:03:20] <r00t4rd3d> tom why dont you port forward 80 to 81?
[10:03:33] <r00t4rd3d> or just use 80
[10:03:41] <Tom_itx> isp block
[10:03:59] <r00t4rd3d> router?
[10:04:06] <r00t4rd3d> port all 81 requests to 80
[10:04:19] <r00t4rd3d> then you can remove the :81
[10:04:27] <Tom_itx> my isp blocks outbound 80
[10:04:35] <r00t4rd3d> they cant
[10:04:46] <Tom_itx> as well as a few others
[10:04:47] <r00t4rd3d> you wouldnt be able to use the internet
[10:05:02] <r00t4rd3d> inbound 80s maybe
[10:05:09] <Tom_itx> well that then
[10:06:27] <r00t4rd3d> dyndns should have some option to port forward also
[10:07:24] <jthornton> Tom_itx, http://www.anaheimautomation.com/manuals/brushless/L010676%20-%20MDC010-024031%20Users%20Guide.pdf
[10:09:53] <r00t4rd3d> set apache up to use port 81
[10:10:23] <r00t4rd3d> and open that port on your router
[10:10:34] <r00t4rd3d> then you should be able to drop the :81
[10:11:34] <Tom_itx> i did i think
[10:11:48] <Tom_itx> apache listens on 81
[10:20:03] <Tom_itx> jthornton, is 17 an adc input voltage?
[10:20:10] <Tom_itx> dac
[10:20:45] <r00t4rd3d> anyone make clocks?
[10:20:54] <Tom_itx> and 11 & 12 set the rpm range
[10:23:21] <jthornton> Tom_itx, I think so
[10:27:52] <Tom_itx> Set value Speed - Analogue input (0-5V); Resolution: 1024 Steps
[10:37:13] <jthornton> on the Inputs what does 1 Pole Pair, 4 Pole Pair, 8 Pole Pair mean?
[10:37:22] <jthornton> page 4
[10:39:41] <Tom_itx> good q
[10:40:27] <andypugh> Talking about motors?
[10:40:39] <Tom_itx> http://www.anaheimautomation.com/manuals/brushless/L010676%20-%20MDC010-024031%20Users%20Guide.pdf
[10:40:41] <andypugh> It's the number of, err, pole pairs :-)
[10:40:44] <Tom_itx> that little driver
[10:40:51] <jthornton> I think so it is on a chart for the driver
[10:42:30] <jthornton> ok, I think I see it on the specs of the motor
[10:42:42] <jthornton> winding type: Star, 4 poles
[10:43:36] <Tom_itx> how do poles and phase correlate?
[10:44:01] <jthornton> good q
[10:44:07] <Tom_itx> andypugh?
[10:44:57] <Tom_itx> maybe it's like a hybrid stepper
[10:45:52] <Tom_itx> http://answers.yahoo.com/question/index?qid=20090401164149AA852gp
[10:45:56] <Tom_itx> :)
[10:51:44] <andypugh> A brushless motor will (almost) always be three-phase.
[10:51:56] <Tom_itx> yeah
[10:58:21] <pcw_home> common exception is a step motor which is a brushless 2 phase normally 50 pole motor
[11:01:07] <andypugh> This is what you get when you run a stepper as a brushless. http://www.youtube.com/watch?v=2SozZ7af3wg
[11:03:31] <jthornton> so that is a stepper with hall feedback?\
[11:03:39] <andypugh> Encoder feedback.
[11:03:50] <jthornton> cool
[11:04:04] <andypugh> Though you probably _could_ do it with halls.
[11:04:54] <pcw_home> You need to have about 10 times the step size encoder resolution
[11:05:12] <andypugh> Hmm. Using halls as encoder feedback on steppers is a really neat idea. Is there a patent lawyer in the house?
[11:06:19] <andypugh> pcw_home: For an encoder, yes. But if you are tracking whether the last step "worked" and not sending the next step until has...
[11:07:15] <r00t4rd3d> every app Vectric makes is awesome
[11:11:07] <pcw_home> Yeah if it were just used to keep in sync with the rotor (and not get better than 1/2 step or so resolution)
[11:12:24] <pcw_home> Is seems to me you would have to mimic the rotor/stator magnetics away from the stator coils (a rotor extension)
[11:13:10] <andypugh> It might be worth an experiment. I can imagine it would be easy to make replacement motor end-covers.
[11:13:25] <pcw_home> just 2 sensors
[11:13:37] <andypugh> I am not sure if I have any small-enough Halls lying about.
[11:13:52] <Tom_itx> andy just want's to play with his little hall sensors
[11:16:48] <L84Supper> http://www.google.com/patents/US5256943 Zero adjustment shaft encoder control for stepping motors
[11:18:40] <pcw_home> Jeez trivial and obvious
[11:18:55] <pcw_home> how else would you do it
[11:22:51] * jthornton has almost found the top of the desk down here in the beer cave
[11:23:05] <jthornton> another few inches to go I suspect
[11:23:36] <pcw_home> But if you could use the magnetic rotor of a hybrid stepper and so matching pole pieces on a HAL stator pickup with interpolation, then you would have something (a absolute over one electrical rotation relatively high res encoder permanently synced with the rotor)
[11:35:21] * jthornton wonders why the forum give an error now if you try and download a .py file?
[11:35:56] <r00t4rd3d> it wants cake
[11:44:48] <r00t4rd3d> whats the error?
[11:44:48] <jthornton> hmmm new user Nina Santamaria from Bogota Colombia... spammer or not?
[11:45:07] <r00t4rd3d> nah, she has your money!
[11:45:43] <jthornton> http://www.linuxcnc.org/images/fbfiles/files/gaxis.py
[11:46:46] <andypugh> I wouldn't assume that she is a spammer, but would be suspcious. I share an office with a Colombian, so they clearly do engineering.
[11:47:20] <r00t4rd3d> wait, what?
[11:47:20] <jthornton> but would their name be after three ships
[11:47:39] <jthornton> or two as the case may be
[11:49:12] <r00t4rd3d> classifying all colombians based on one you work with is not a sane thought
[11:49:36] <jthornton> seems to be a real address afaikt
[11:49:44] <jthornton> afaict
[11:49:46] <r00t4rd3d> ask for pics
[11:50:08] <r00t4rd3d> or cocaine
[11:51:01] <andypugh> She sounds cute, let her in :-)
[11:51:45] <r00t4rd3d> you are gonna get spammed
[11:52:24] <r00t4rd3d> you might as well open a can and rub it into your chest
[11:53:24] <andypugh> "The Niña, the Pinta, and the Santa Maria were the ships that Columbus took on his first journey to the new world."
[11:53:34] <Tom_itx> andy are you saying all columbians are bad?
[11:53:36] <Tom_itx> :)
[11:54:03] <Tom_itx> one of my ancestors was on one of those ships too
[11:54:06] <r00t4rd3d> they are either smart cause they work with him or he is dumb cause he works with them
[11:54:19] <jthornton> andypugh, that's what I was referring to...
[11:54:45] <Tom_itx> innocent coincidence
[11:54:50] <jthornton> and every name ends with an 'a'
[11:55:23] <Tom_itx> i know 3 mexicans named Jesus... are they ok?
[11:55:57] <jthornton> I think there are 25 million mexicans named heyzuse

[11:56:03] <Tom_itx> heh
[11:56:16] <Tom_itx> and likely are all related
[11:57:11] <Tom_itx> ok i gotta find one more old monitor
[11:57:13] <andypugh> http://www.youtube.com/watch?v=y_IrkdXAOkk indicates that ninasanta1 is a Solidowrks user.
[11:58:29] <Tom_itx> i wish i could use solidworks that fast
[11:59:02] <jthornton> must be on speed
[12:07:00] <taiden> what do you guys think of running 1/8" shank bits in a 1/4" or 1/2" collet with an adapter bushing?
[12:07:06] <taiden> for cutting hardwoods
[12:09:39] <andypugh> Better to use a different collet
[12:09:46] <jthornton> sounds like nap time to me
[12:13:28] <taiden> yeah..
[12:13:36] <taiden> man I really am a cheap ass
[12:13:58] <mcenter> Jesus loves you is a fine sentiment when heard in church, but rather terrifying when heard in a Mexican prison.
[12:17:06] <taiden> http://24.media.tumblr.com/tumblr_lxq32wjlAY1qil96wo1_500.jpg
[12:17:09] <taiden> related pic is related
[12:21:02] <taiden> definitely like writing gcode more than I like making parts
[12:21:27] <taiden> maybe that confirms that i should be majoring in computer science instead of mechanical engineering
[12:25:07] <andypugh> I like that I have to choice to do which I fancy at the time.
[12:25:57] <andypugh> Just watched the Women's Team Pursuit. I really thought that they might catch them :-)
[12:31:36] <jthornton> yea! I just got a custom gui to toggle the estop and power in Linuxcnc
[12:31:52] <andypugh> W00t!
[12:32:02] <jthornton> now to figure out how to run it without Axis...
[12:32:07] <taiden> woop!
[12:32:13] <taiden> some day I will dive into that
[12:32:28] <taiden> for now my absurd nested subroutines stored in files seem to work LOL
[12:32:30] <jthornton> it has just became much easier for me up to this point
[12:33:09] <taiden> can the custom gui run gcode direct or does it have to reference a file?
[12:33:41] <jthornton> I assume you could do what ever you want somehow
[12:34:12] <jthornton> I have pyvcp buttons that run a mdi command that calls a file...
[12:35:09] * jthornton really hears a nap calling his name now
[12:36:35] <taiden> did I hear the word PYTHON?
[12:36:40] <taiden> be still my beating heart

[13:53:36] <geo01005Farm> It apears to be connected to the G38.3 probe at line 40
[13:54:23] <geo01005Farm> Sorry, Line 40 should have the () removed.
[13:55:28] <jthornton> so do you have it figured out?
[13:55:48] <geo01005Farm> no, I just pasted it wrong in the pastebin
[13:56:01] <jthornton> ok
[13:59:39] <geo01005Farm> it looks like there is something wrong with o399
[13:59:52] <geo01005Farm> lines 41-50
[14:00:11] <jthornton> I thought you said it was the wrong pastebin?
[14:00:23] <andypugh> Try a space after LOG,
[14:00:55] <andypugh> Ah, no, it woin't be that, as it will just ne seen as a comment if it was wrong.
[14:01:30] <jthornton> what line does the error happen at?

[14:06:36] <geo01005Farm> I'm sure there are still lots of other bugs, I just could see that one.
[14:07:49] <jthornton> geo01005Farm, a good practice to have a preamble at the top of your g code
[14:08:25] <geo01005Farm> It looks like it is a bit of a pain to use parameters 5420 etc along with probing...
[14:08:58] <geo01005Farm> Thanks jthornton, I'll keep that in mind.
[14:09:22] <jthornton> want a link to the tutorial?
[14:10:01] <geo01005Farm> Sure/

[14:11:07] <Tom_itx> i really gotta get my probe hooked up
[14:11:28] <Jymmm> thats what she said
[14:13:27] <geo01005Farm> anybody know how to get the current location (in a parameter) after probing?
[14:13:50] <geo01005Farm> It says #5420 is out of range after a probe move
[14:15:11] <pcw_home> thats what she said
[14:15:24] <Tom_itx> she's a chatty little thing

[14:16:23] <Jymmm> Tom_itx: only because you haven't inserted your probe in the correct socket
[14:17:08] <jthornton> does sound like a mistoke in your code again
[14:22:55] <andypugh> is a mis-toke when you don't inhale?
[14:23:15] <Jymmm> andypugh: when you dont exhale
[14:25:46] <Jymmm> I'm looking for these but with a machine thread, anyone know the proper name? (Note the closed eye, unlike an 'eye bolt') http://images.drillspot.com/pimages/12045/1204509_300.jpg
[14:27:27] <andypugh> Try "forged eye" http://www.ukfixings.net/M6-Forged-Eye-Bolt-Box-of-50.html
[14:29:10] <Jymmm> andypugh: They are coming up but huge, I need about 10-24 thread
[14:29:29] <andypugh> The one I liked was M6
[14:29:33] <andypugh> )linked)
[14:29:45] <r00t4rd3d> aww you liked it!
[14:31:08] <Jymmm> andypugh: The OD of the eye is far too wide, I need that 1/4" at the widest
[14:31:37] <andypugh> Ah, OK.
[14:32:24] <andypugh> Try starting with who might use what you want, and what for.
[14:32:48] <Jymmm> andypugh: The closest I've found a tie rods

[14:34:13] <r00t4rd3d> all icing, made by a guy :/
[14:34:16] <jthornton> Jymmm, you looking for a rod end?

[14:34:47] <Tom_itx> ?
[14:34:48] <Jymmm> jthornton: Only if it's 2-3" long =)
[14:34:59] <jthornton> they come in all sizes
[14:35:06] <Tom_itx> that's what she said
[14:35:12] <Jymmm> Tom_itx: the head OD can't be more than 1/4"
[14:36:12] <Jymmm> jthornton: The rod ends have too wide a head on them it seems
[14:36:19] <r00t4rd3d> well he just meets that criteria
[14:36:50] <Jymmm> I need what I linked but in machien thread instead of wood thread
[14:37:04] <andypugh> How many?
[14:37:07] <jthornton> maybe your looking at one that is too big?
[14:37:09] <Jymmm> Just not sure of the proper name to search for it
[14:37:16] <r00t4rd3d> bolt
[14:37:51] <andypugh> What goes in the eye?
[14:37:52] <Jymmm> jthornton: google images search

[14:40:32] <Jymmm> Tom_itx: now to find in 10-24 instead of 1/4-28 =)
[14:41:27] <Jymmm> andypugh: I'm looking at the drawing, but I'm not seeing it
[14:41:49] <andypugh> Eyes open? Looking at the right side of the monitor?
[14:42:56] <andypugh> What are you not seeing?
[14:43:05] <Tom_itx> http://www.fastenal.com/web/products/detail.ex?sku=0543554
[14:43:07] <Tom_itx> wrong way
[14:43:11] <Jymmm> andypugh: Ah, ok... This isn't terminating the END of a cable, but looped thru the cable.
[14:43:48] <Jymmm> Tom_itx: Yeah, fastenal is usually construction materials
[14:46:25] <Jymmm> They are called 'swing bolts'
[14:46:44] <Tom_itx> swage eye bolt

[14:51:31] <jthornton> np
[15:01:00] <joe9> i added a tool length probe switch. instructions at http://forscience.nl/?p=144 work fine. I can see the False and True states in HalMeter.
[15:01:16] <joe9> Now, I am checking this out http://forscience.nl/?p=197
[15:01:52] <joe9> and it feels that I do not need it. I just need to program M6 so that the machine automatically does a "tool length" probe, whenever there is a tool change.
[15:02:19] <joe9> Is adding the gui component as mentioned in the tutorial superior to just a custom program to M6?
[15:02:25] <joe9> any thoughts, please?
[15:03:00] <joe9> i see the instructions here: http://softsolder.com/2010/04/14/emc2-ugliest-tool-length-probe-station-ever/ and they do not seem to be for M6
[15:03:24] <joe9> It just seems to be a standalone program for "tool length probe". I could be wrong.
[15:03:59] <jthornton> to change the behavior of M6 you will need to look at master
[15:04:10] <jthornton> do you need a link to the documents on that?
[15:04:16] <joe9> andypugh: any thoughts, please?
[15:04:28] <joe9> jthornton: I think I am going down the wrong path.
[15:04:40] <andypugh> Which path do you want to go down?
[15:04:45] <joe9> I don't want to change how M6 works. just to call this tool length probe function when M6 happens.
[15:05:02] <joe9> andypugh: is this what you meant yesterday?
[15:05:12] <andypugh> So, you are happy to have an extra bit of G-code after the M6 command/
[15:05:22] <joe9> andypugh: i want to stick with your recommendation. so, that any tool change automatically does the length check.
[15:05:35] <andypugh> Then you need to change M6
[15:05:45] <andypugh> Ah, actually...
[15:05:49] <andypugh> You might not need to.
[15:06:10] <jthornton> classicladder?
[15:06:16] <joe9> oh, ok. how about a sed script that "s/M6/M6 <more gcode>/g" for my gcode programs?
[15:06:19] <joe9> is that good enough.
[15:06:26] <andypugh> MDI_COMMAND on the tool-change pin...
[15:08:09] <joe9> http://softsolder.com/2010/12/06/improved-tool-length-probe-switch/ seems to be pretty good.
[15:08:19] <joe9> andypugh: is ^^ that how you are thinking?
[15:09:22] <andypugh> I am not thinking. You are the one doing the thinking.
[15:09:23] <joe9> andypugh: is there something that I can do to replicate the homing behaviour for tool length probe too?
[15:10:18] <r00t4rd3d> i like this http://emergent.unpythonic.net/01216264526
[15:10:25] <r00t4rd3d> i think andy posted it
[15:10:50] <joe9> r00t4rd3d: that is the switch I have
[15:10:59] <joe9> i worked off of it.
[15:11:02] <r00t4rd3d> i could make that, just not sure how to set it up
[15:11:41] <r00t4rd3d> i think you could use that as a z homing switch
[15:11:57] <joe9> but, could not find any gcode on how it works.
[15:12:41] <r00t4rd3d> it would be your machine setup, not gcode
[15:13:24] <r00t4rd3d> you would set that switch to z home in the parallel settings
[15:13:46] <joe9> r00t4rd3d: i have the same switch and wired similarly.
[15:13:49] <joe9> r00t4rd3d: gotcha.
[15:13:59] <joe9> so, this new switch will become the z-home switch.
[15:14:02] <r00t4rd3d> im guessing though
[15:14:04] <joe9> is that what you mean?
[15:14:07] <r00t4rd3d> yeah
[15:14:17] <joe9> i already had a z-home switch at the top.
[15:14:33] <joe9> which I use as a limit switch too.
[15:14:48] <joe9> I just wanted to add a tool length probe switch to measure the tool length.
[15:15:10] <joe9> I want the existing limit switch to work
[15:15:24] <joe9> r00t4rd3d: does that make sense?
[15:16:38] <r00t4rd3d> im not sure on probes at all
[15:16:43] <jthornton> anyone want read step 1 of creating your custom gui for linuxcnc?
[15:16:56] <r00t4rd3d> how many pages is it?
[15:17:21] <jthornton> 1
[15:17:44] * Jymmm will wait for the movie to come out
[15:18:06] <r00t4rd3d> Debbie Does Customs?
[15:19:58] <andypugh> joe9: I just managed to make LinuxCNC run G-code automatically after a tool-change using MDI_Command. But I have a feeling it won't work inside a program.
[15:21:12] <joe9> andypugh: Do you think this could work for me? http://softsolder.com/2010/12/06/improved-tool-length-probe-switch/ Is this what you had in mind when you recommended the tool length probe.
[15:21:22] <joe9> not exactly that but that idea, I mean.
[15:21:50] <andypugh> I have no idea which "idea" there you are talking about.
[15:23:11] <andypugh> Yes, you probably could bolt a microswitch to your machine table.
[15:23:27] <andypugh> Yes you could use G-code to control the probe move.
[15:24:53] <Jymmm> joe9: a micro switch with a long lever on it would provide more sensativity if you need it http://www.isplc2006.org/b2b/pics/Micro_Switch.jpg
[15:25:15] <andypugh> Jymmm: Les sensitivity
[15:25:19] <Jymmm> and a little lead room if over traveled
[15:25:48] <r00t4rd3d> http://www.liveleak.com/view?i=9d6_1344053879
[15:26:50] <Jymmm> andypugh: more precision?
[15:27:50] <andypugh> No. It takes more travel to operate the switch with the lever, so variations in switching point are larger variations in tool travel.
[15:29:48] <Jymmm> andypugh: more macho?
[15:33:25] <andypugh> joe9: If you look in the "examples" section of the nc_files directory you ought to find a file called "tool_length_probe.ngc"
[15:33:32] <joe9> "Yes, you probably could bolt a microswitch to your machine table." -- I have done this.
[15:33:41] <joe9> I can check the switch from halmeter.
[15:33:55] <joe9> "Yes you could use G-code to control the probe move." -- I do not have a clue how to go about this.
[15:34:05] <alex4nder> yoh
[15:34:07] <joe9> I have written gcode and have limit/home switches configured
[15:34:12] <andypugh> joe9: If you look in the "examples" section of the nc_files directory you ought to find a file called "tool_length_probe.ngc"
[15:34:43] <joe9> andypugh: ok, will check it out. thanks.
[15:35:52] <joe9> andypugh: thanks, that is exactly what I was looking for.
[15:35:57] <joe9> andypugh: that is helpful.
[15:36:55] <andypugh> It looks like 8 lines of Gcode. You could just insert it when required, or put it in a named subroutine and use O<toollength> call
[15:38:18] <andypugh> The alternative is to change the behaviour of M6, which is possible, but not trivial: http://www.linuxcnc.org/docs/devel/html/remap/structure.html
[15:44:19] <joe9> changing M6 behaviour seems to be a more involved. let me get the subroutine stuff working first.
[15:51:49] <mhaberler> hey, it's dead simple, it's just a oword sub (with an admittedly pathetic but one-off & preconfigured calling sequence ;-)
[16:12:26] <DJ9DJ> gn8

[16:19:53] <r00t4rd3d> http://i.imgur.com/qgkil.jpg
[16:23:24] <andypugh> It appears to be more of a sundial without a gnomon.
[16:23:57] <r00t4rd3d> i need some clock parts
[16:24:13] <r00t4rd3d> im fresh out
[16:25:20] <archivist> I haz stock of quartz clock movements
[16:25:29] <andypugh> If I may be excused some pedantry, you have made a nice clock-face, and now need a clock.
[16:32:40] <jthornton> sombitch! my GUI runs without Axis!!!!
[16:38:20] <r00t4rd3d> http://www.microcarve.com/forum002/bbx-paint/
[16:40:31] <jthornton> http://imagebin.org/223307
[16:42:01] <jthornton> quit from menu
[16:42:01] <jthornton> Shutting down and cleaning up LinuxCNC...
[16:42:01] <jthornton> Cleanup done
[16:42:39] <andypugh> Does it also run G-code, or just display it?
[16:43:30] <jthornton> as soon as I add the run, stop button it will run G code
[16:43:47] <jthornton> all I have so far is the open file and the gremlin to display it
[16:43:57] <jthornton> I'm just stoked it worked
[16:44:37] <andypugh> Ah, yes, it's a GUI option in the INI isn't it?
[16:45:05] <jthornton> yes! I ran it from the INI
[16:46:16] <andypugh> And those Mach dudes say you can't customise the GUI in LinuxCNC! Hah, you can write it from scratch. Err, actually, you have to write it from scratch..
[16:47:21] <jthornton> it's so simple really once you put a few lines of code together with the glade screen.
[16:48:06] <jthornton> I have 37 lines of code to get what you see there and won't need any more for standard linuxcnc actions
[16:48:47] <jthornton> I'd guess in 30 minutes following my tutorial you could have a working GUI up and going
[16:48:50] <andypugh> I wonder if there is an argument for re-making Axis in Glade?
[16:49:16] <jthornton> you could
[16:49:34] <jthornton> it would play nicer with GladeVCP that's for sure
[16:49:47] <andypugh> Then we could have a GUI-editable GUI.
[16:50:31] <jthornton> and you could have it default to max screen size with no pain and suffering
[16:53:01] <r00t4rd3d> built in xchat and add a tab
[16:53:04] <Jymmm> kiosk mode
[16:53:49] <Jymmm> order pizza
[16:54:08] <Jymmm> pour beer
[16:54:43] <Jymmm> tell you when to flip the ribs/steaks on the grill
[16:54:44] <andypugh> r00t4rd3d: I think you could already do that
[17:01:06] <jthornton> andypugh, just running a G code file now
[17:01:12] <jthornton> that is amazing
[17:01:38] <andypugh> I am rarther impressed, I have to say.
[17:02:19] <jthornton> all I had to do was add the actions for run pause and stop to my glade file
[17:02:32] <andypugh> Folk have been describing LinuxCNC as modular for a long time, but it seems that we have only recently started to experiment with that.
[17:03:09] <andypugh> Pavel's work in GladeVCP is what makes it all possible, I think?
[17:04:19] <jthornton> yes I think your correct and Chris Morley's work with gscreen
[17:04:39] <jthornton> and Chris Morley telling me how to do it...
[17:06:27] <andypugh> I assume that wasn't mah leavingin a huff?
[17:11:33] <Jymmm> andypugh: why would he?
[17:11:48] <Jymmm> andypugh: what did you do?
[17:12:09] <andypugh> Well, he was involved in GladeVCP too.
[17:13:01] <Jymmm> ok, and?
[17:15:03] <Jymmm> he doesn't like when ppl think it's amazing?
[17:15:29] <andypugh> I gave the credit elsewhere?
[17:15:53] <Jymmm> oh, I dont know who pavel is
[17:16:04] <andypugh> psha
[17:16:07] <Jymmm> ah
[17:17:02] <Jymmm> well, *IF* by a slight chance it is, he'll get over it.
[17:18:06] <jthornton> I should give mah credit for this "Pavel committing a patch ;-)" http://www.liveleak.com/view?i=4cf_1343665540
[17:19:38] <Jymmm> wtf
[17:19:39] <andypugh> looks like they got away with it.
[17:19:48] <Jymmm> grenade?
[17:20:05] <Jymmm> (suicide) grenade
[17:20:10] <andypugh> Maybe a floating grenade?
[17:20:20] <jthornton> short fuse I'd think
[17:20:31] <andypugh> But it seemed like a very short timer
[17:20:32] <Jymmm> one thing for sure, dumbasses with a grenade
[17:20:54] <Jymmm> 2s fuse
[17:21:50] <jthornton> I can't quit staring at jtgui
[17:22:19] <Jymmm> jt? he's such a whore.
[17:22:55] <andypugh> I am working on laser-rasta-gui. Or, rather, the motion controller for it.
[17:23:16] <Jymmm> rasta?
[17:23:20] <Jymmm> ya mon
[17:23:35] <andypugh> Yeah, I like the idea of Bob Marley with a laser.
[17:23:59] <Jymmm> precision doobage?
[17:24:27] <andypugh> I suspect it might all be a bit vague, actually.
[17:28:28] <joe9> HOME_LATCH_VEL = 0.050000
[17:28:31] <joe9> is that too high?
[17:28:39] <joe9> i have a search velocity of 0.1
[17:28:46] <joe9> this is in inches
[17:33:23] <andypugh> Search vel should be as high as possible such that the machine can still stop before crushing or over-running the switch.
[17:34:30] <andypugh> latch_vel should be as slow as makes sense given the accuracy of your switch. Think in terms of how far the machine moves in 1mS
[17:35:31] <joe9> oh, once I think in terms of mS, then I guess what I have is not that bad.
[17:35:32] <joe9> thanks.
[17:49:01] <r00t4rd3d> http://i.imgur.com/rWy9J.jpg
[17:52:10] <Tom_itx> did i hear andypugh volunteer to rewrite axis in glade?
[17:52:17] <Tom_itx> looks nice jthornton
[17:52:23] <jthornton> yea, I think that's what he said
[17:52:25] <jthornton> thanks
[17:52:40] <andypugh> Tom_itx: No, you heard me asking for volunteers. Well done.
[17:53:15] <Tom_itx> how hard would it be?
[17:53:38] <andypugh> If ye ken Python, posibly quite easy.
[17:53:51] <Tom_itx> i don't know python or glade
[17:53:54] <andypugh> Actually, the Python already exists,.
[17:53:58] <Tom_itx> but i'm interested in it
[17:54:07] <andypugh> Well, perhaps you ought to learn :-)
[17:54:12] <jthornton> read my tutorials
[17:54:18] <Tom_itx> perhaps you should teach us
[17:54:35] <andypugh> Who is "you"?
[17:54:43] <Tom_itx> yeah you
[17:54:57] <andypugh> I know _nothing_ about Pythin
[17:55:04] <Tom_itx> i'm doing good to boot linux
[17:55:08] <andypugh> I can't even spell it.
[17:55:11] <Tom_itx> heh
[17:55:36] <Tom_itx> jthornton you're using the builtin gui for linuxcnc with a glade front end?
[17:55:46] <Tom_itx> err backend of linuxcnc
[17:55:58] <joe9> i have this setup in my .hal file: http://codepad.org/W6bBDgLV
[17:56:16] <joe9> How do I know when this "tool-length-probe-in-filtered" is triggered?
[17:56:19] <joe9> in gcode.
[17:56:29] <joe9> in halmeter, I can debounce.0.3.out
[17:56:31] <jthornton> Tom_itx, ?
[17:56:39] <joe9> see that the value is being triggered.
[17:56:54] <jthornton> GladeVCP and LinuxCNC and a little python
[17:56:57] <joe9> but, am not sure how to read this "tool-length-probe-in-filtered" in gcode.
[17:57:16] <Tom_itx> jthornton, how do you hook glade to the backend of linuxcnc?
[17:58:06] <jthornton> that will be in tutorial 3 and it is only a few lines long
[18:00:04] <Tom_itx> so what do i need to load to get started?
[18:00:16] <Tom_itx> i can put off my touch probe longer :)
[18:00:33] <jthornton> to get started with GladeVCP?
[18:00:55] <Tom_itx> isn't gladevcp builtin linuxcnc as a front end option?
[18:01:10] <Tom_itx> are you using glade or gladevcp?
[18:01:15] <jthornton> yes
[18:01:20] <Tom_itx> :)
[18:01:20] <jthornton> and python
[18:01:39] <Tom_itx> glade does the screen and python makes it work
[18:02:08] <jthornton> gladevcp makes it work really if I understand correctly
[18:05:37] <jthornton> Tom_itx, did you read part one of the gui tut?
[18:07:40] <Tom_itx> gettin ready to
[18:07:51] <Tom_itx> lookin for a better keyboard
[18:07:55] <Tom_itx> no way can i program with that crap one
[18:11:42] <r00t4rd3d> I am going to make a mini grandfather clock
[18:12:25] <atom1> ok this one may work
[18:14:12] <Tom_itx> jthornton where do i get glade3?
[18:14:18] <Tom_itx> i see 2 in the package manager
[18:14:44] <jthornton> I think I just went to Ubuntu Software Center on the menu
[18:17:19] <atom1> doesn't say what ver it is
[18:17:52] <jthornton> I'd bet it is 3.6.7
[18:19:01] <atom1> the package manager says i have python-glade2 already, is that something else?
[18:20:15] <atom1> ok this keyboard sucks too
[18:39:29] * Tom_itx makes a general arm sweep across the desk to make room
[18:47:56] <jthornton> Tom_itx, did you get it sorted out?
[18:48:04] <Tom_itx> yeah
[18:48:12] <Tom_itx> i'm reading
[19:03:14] <Tom_itx> jthornton, typo in your demo1 code
[19:03:33] <jthornton> where?

[19:17:07] <jthornton> yes you did
[19:17:31] <jthornton> I'm going to change that so you don't have to change the window name soon...
[19:17:55] <Tom_itx> i'll start over
[19:18:24] <Tom_itx> it's a bit confusing here, i have 4 monitors/kbds on the desk atm
[19:18:35] <jthornton> I know that feeling
[19:19:08] <atom1> starting the glade part fresh
[19:19:57] <jthornton> I see a typo that might confuse you
[19:20:48] <jthornton> if you copy and paste tutorial-1.py it has a typo just use the link for now
[19:20:55] <jthornton> and thanks for testing this
[19:21:01] <Tom_itx> ok, np
[19:23:06] <jthornton> ok refresh your browser, I've fixed the misleading typo
[19:23:16] <Tom_itx> too late
[19:23:55] <Tom_itx> what was it?
[19:24:51] <jthornton> the first listing of tutorial-1.py had get_object("main_window") instead of window1
[19:25:27] <Tom_itx> oh
[19:25:55] <jthornton> bbl
[19:26:40] <Tom_itx> ok
[19:26:53] <Tom_itx> at least gracie isn't looking for you yet
[19:29:35] <Tom_itx> ok it ran that time
[19:43:11] <pcw_home> man its cold here, never got above 60F today
[20:01:40] <jthornton> send some our way it is 95F every day
[20:01:59] <Tom_itx> the emc lib should be renamed in glade
[20:02:16] <ReadError> i wish i had a manual rapid button
[20:02:20] <jthornton> so in hind sight Tom_itx anything in the tutorial need changing?
[20:02:25] <ReadError> so i dont have to put it in the code
[20:02:35] <ReadError> a turbo key that went to the specified velocity when held
[20:02:36] <ReadError> mmm
[20:02:49] <Tom_itx> not yet but it was a bit confusing where the 'credits' and 'license' came form
[20:02:56] <Tom_itx> from*
[20:03:21] <atom1> on the 2nd one
[20:03:33] <atom1> starting #3
[20:03:37] <atom1> got interrupted
[20:03:54] <jthornton> on the help about screen?
[20:04:02] <atom1> yes
[20:04:33] <jthornton> hmmm
[20:05:09] <jthornton> maybe expand the General tab to show them?
[20:05:41] <atom1> well most won't be as noob as me
[20:05:59] <atom1> this is the first time i've messed with glade at all
[20:06:08] <jthornton> gotta assume you know nothing at the start
[20:06:23] <atom1> that's hard to do when you're writing a tutorial
[20:06:25] <atom1> i know
[20:06:35] <jthornton> thanks for the feedback on that
[20:07:02] <atom1> it doesn't help i'm using 2 screens
[20:07:22] <atom1> i think once i re read that it's ok
[20:08:24] <atom1> ie, 'when you start typing in the 'license' dialog, the Licence button will appear on the screen
[20:08:48] <atom1> so far we have been draging stuff from the left side
[20:09:46] <jthornton> is this a better image? http://imagebin.org/223333
[20:10:37] <Tom_itx> yeah
[20:13:29] <jthornton> ok updated the image and changed the word "stuff" to "text"
[20:13:37] <Tom_itx> hah
[20:14:13] <jthornton> time to flick on the magnetassswitch
[20:15:37] <Tom_itx> did you add your controls from the emc stuff on the left?
[20:22:06] <Tom_itx> your tutorial-2 python file needs renamed
[20:24:11] <Tom_itx> no it seems ok now, i'm not sure what i did
[20:26:55] <Tom_itx> yeah i got an error on it
[20:40:34] <Tom_itx> just froze glade
