[00:05:47] <atom1> i wonder if i skipped a step
[00:05:51] <jthornton> when you made the main window you didn't name it the same
[00:05:53] <jthornton> yes you did
[00:06:18] <jthornton> I'm going to change that so you don't have to change the window name soon...
[00:06:41] <Tom_itx> i'll start over
[00:07:11] <Tom_itx> it's a bit confusing here, i have 4 monitors/kbds on the desk atm

[03:32:01] <Jymmm> This 1959 MIT Science Reporter television program describes the APT project, a novel system for the computerization of numerical control being developed at the new Electronic Systems Laboratory by colleagues John Francis Reintjes and Douglas Taylor Ross. Reintjes and Ross discuss their work using the WHIRLWIND I computer to develop an automatic programming system for numerical control in two dimensions known as APT (automatically programmed
[03:32:02] <Jymmm> tool). MIT ESL worked on APT with US Air Force support and in cooperation with Aerospace Industries Association. The project marked MIT's first government/industry/university joint effort

[11:41:36] <ktchk> Hi loypad control anyone know how to touchup by a remote btn?
[11:42:35] <ktchk> joypad
[11:42:57] <andypugh> Touch-off to zero? Or do you have a way to enter numbers from the joypad?
[11:44:17] <ktchk> I am on the workpiece zero now I wanted to push the touchup buton how?
[11:44:34] <jthornton> what is touchup?
[11:44:53] <andypugh> It's like touch-off I guess, but more fun
[11:44:58] <jthornton> I see
[11:45:04] <jthornton> howdy Andy
[11:45:10] <ktchk> put the system to zero on workoiece
[11:45:31] <ktchk> workpiece
[11:45:37] <andypugh> ktchk: You can link a buttton to an MDI_COMMAND which issues a G10 command.
[11:46:35] <ktchk> the catch is the line in .hal file. any example?
[11:46:41] <andypugh> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Adding_Custom_MDI_Buttons
[11:47:26] <jthornton> my old plasma screen :)
[11:47:42] <ktchk> can the mdi command set up the advance of xyz to 1mm or .1mm?
[11:47:52] <andypugh> (You would link to the physical button input pin rather than the pyvcp pin in that example, and your MD_COMMAND G-code would be a G10 of some flavour.
[11:48:27] <andypugh> ktchk: Yes. The problem is, in fact that it has to be set up in advance and can't easily be changed.

[15:36:06] <Tom_itx> overall i like the tutorials
[15:36:35] <jthornton> thanks, if you get a chance read through them again and see if I fixed all the things you noticed
[15:36:39] <Tom_itx> starting from scratch installing glade i was able to get up to 4
[15:37:09] <Tom_itx> i noticed you added more 'where is' things
[15:38:10] <jthornton> yea, last time around I was able to concentrate on the tutorial and not trying to learn as I go
[15:38:30] <Tom_itx> you might consider zipping the whole set as one download somewhere too
[15:38:48] <jthornton> good idea
[15:38:58] <Tom_itx> it's not easy writing a tutorial and describing it as you go
[15:40:59] <jthornton> no, it is not
[15:41:00] <Tom_itx> :) now the .py files are 404
[15:41:12] <jthornton> yea they are gone, do a refresh
[15:42:38] <Tom_itx> If you haven't already downloaded the set: Open up the tutorial-2.glade file and save as tutorial-3.glade.
[15:43:11] <Tom_itx> i wouldn't include the glade in the zip really
[15:43:31] <Tom_itx> going thru the steps makes you get familiar with glade which is good
[15:43:57] <jthornton> if you just click on the glade it opens up in the browser and looks like gobbly gook
[15:44:13] <Tom_itx> you can 'save as' though
[15:44:42] <Tom_itx> i may have done that on a couple when the names didn't match
[15:45:01] <Tom_itx> did you get the name change in the code?
[15:45:06] <Tom_itx> menuitem i think it was
[15:45:28] <jthornton> I'm not sure let me look
[15:45:59] <Tom_itx> the 'View' wouldn't display on the status bar
[15:46:19] <Tom_itx> tut 3
[15:46:23] <Tom_itx> i think
[15:46:44] <jthornton> might not have pressed enter after selecting the signal handler
[15:48:15] <Tom_itx> i'm not sure i was ever told to change the status bar name, i'm looking
[15:49:08] <jthornton> I've changed all that name changing stuff to use the default names to reduce confusion.
[15:49:36] <Tom_itx> heh
[15:49:51] <Tom_itx> it's good to make the user change stuff though
[15:49:59] <Tom_itx> gets them used to being able to
[15:59:55] <jthornton> ok the 5th one is updated
[16:00:38] <Tom_itx> on the Edit Menu Bar dialog, when i go to the activate dropdown list, it doesn't work on mine. I have to type the name in, unlike the main screen.
[16:00:58] <Tom_itx> it is greyed out

[18:52:02] <andypugh> London.
[18:54:21] <Tom_itx> london bridges falling down...
[18:58:58] <andypugh> It fell down a long time ago, then a new one replaced it, then that was sold to an American, and they built a third.
[18:59:56] <andypugh> How it works: http://www.selmec.org.uk/article_0009_the_heatherwick_rolling_bridge.aspx
[19:01:04] <Tom_itx> lots of force on the end
[19:01:19] <andypugh> Yes, I imagine it takes a bit of bolting down.
[19:01:35] <jthornton> http://imagebin.org/223407
[19:02:13] <Tom_itx> i may as well not start one then
[19:03:20] <Tom_itx> jthornton do you know how to hook it all to linuxcnc?
[19:03:40] <Tom_itx> is there enough hooks to replace the whole axis front end?
[19:04:22] <jthornton> gscreen touchy and others do it so yea
[19:05:37] <jthornton> what do you think of the DRO design?
[19:06:34] <jthornton> I sure I don't know how to connect "all" to linuxcnc :)
[19:07:34] <Tom_itx> my other program shows 'Program', 'Machine', 'Relative' and 'Distance to Go'
[19:08:00] <Tom_itx> distance to go is handy
[19:09:07] <Tom_itx> machine would be coordinate system
[19:09:33] <jthornton> you can get distance to go
[19:09:52] <jthornton> what is program?
[19:10:05] <Tom_itx> G54
[19:10:08] <Tom_itx> i think
[19:10:24] -!- karavanjo has quit [Read error: Connection reset by peer]
[19:13:31] <Tom_itx> maybe 'active offset' would be better than G92 offset
[19:13:34] <Tom_itx> i dunno
[19:13:41] <Tom_itx> i don't think i use G92
[19:14:07] <jthornton> http://imagebin.org/223413
[19:14:38] <jthornton> active offset is prone to interpretation
[19:17:25] <Tom_itx> i'll throw a pic up of it
[19:17:51] <Tom_itx> you're able to set / zero each one above the displays too

[19:23:09] <Tom_itx> brb phone
[19:23:12] <jthornton> is Machine a machine coordinate
[19:23:19] <r00t4rd3d> I wish linuxcnc told me how many lines of gcode there was overall and how many are left to go.
[19:23:45] <jthornton> you have to ask it
[19:23:50] <r00t4rd3d> even a percentage #
[19:23:55] <r00t4rd3d> 80% done......
[19:24:49] <r00t4rd3d> or if it could calculate the job time from my ipm settings
[19:25:03] <jthornton> that is in the menu
[19:25:19] <r00t4rd3d> where?
[19:28:44] <pcw_home> They dont make them like they used to, our DNS/DHCP server power supply died after ~20 years
[19:30:38] -!- sendoushi has quit [Remote host closed the connection]
[19:31:53] <Tom_itx> jthornton, machine is the 'home' position i think
[19:32:32] <Tom_itx> program is the G54 offset i think since it really doesn't use any others
[19:36:55] <jthornton> this is to go next to the back plot so having lots of extra info displayed would just take up space
[19:36:59] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/jt_shop/coordinate.jpg
[19:37:14] <Tom_itx> you get that when you click on the "SET" button
[19:37:16] <jthornton> you could have a tab with all the info from emc_stat in it :)
[19:37:56] <jthornton> kinda like the Axis touch off window but different
[19:38:45] <Tom_itx> yeah you don't have to switch radio buttons to select the axis
[19:39:29] <Tom_itx> the '0' next to the set zero's all axis for that window
[19:39:31] <jthornton> that has caught me more than once
[19:39:55] <Tom_itx> i actually like flashcut's way better than linuxcnc on that
[19:42:29] <jthornton> when you build your own interface you can have it any way you like and that is the best thing

[21:05:02] <ekacnet> Viesturs asks on how to test a 7i43 + 8i20
[21:05:25] <archivist> tom3p, google suggests he is still at purdue
[21:05:39] <ekacnet> I'm almost in the same situation and would like to know how to check that linuxcnc is communicating correctly with the 8i20
[21:05:54] <tom3p> archivist, were you interested? the C source is very readable ( the geometry primitives like circle tanglent to 2 circles given the typical APT 'above'/left etc )
[21:06:02] <tom3p> archivist, thx
[21:06:25] <archivist> I am interested yes
[21:06:27] <ekacnet> as AC motors I have only quite powerfull ones so I'd like to be sure that things are ok before plugging them
[21:06:58] <ekacnet> and finding small (in terms of power and voltage) AC brushless motors is a bit hard
[21:08:00] <andypugh> ekacnet: The ones from model aircraft are very small.
[21:08:07] <andypugh> Though typically don't have Hall sensors
[21:09:38] <andypugh> Things have moved on a bit in the 8i20 driver. It should just work now. Seeing Bus voltage and temperature is a good clue.
[21:13:33] <ekacnet> andypugh: I'm still with a 2.5.0 and pncconf is by default not generating correctly the .hal file
[21:13:52] <ekacnet> andypugh: do you mean that I can use a DC motor like a 48V DC one ?
[21:14:35] <andypugh> Probably not with an 8i20. The 7i39 would drive a 48V bldc.
[21:15:11] <andypugh> You would need an encoder at the very least though, and preferably halls
[21:16:12] <ekacnet> so as I understand the 8i20 is AC only correct ?
[21:17:32] <ekacnet> and the only way to test it, is to put a load on it, just enabling the drive and powering it with at least 48V won't work ?
[21:18:52] <andypugh> I think we need to be clear on terminology. Brushless AC servos, synchronous permanent magnet motors and brushless DC (BLDC) motors are all pretty much the same thing.
[21:19:24] <andypugh> PMDC (permanent magnet DC) motors are different, and AC Induction motors are different again.
[21:19:46] <andypugh> Both the 8i20 and 7i39 will drive all the first set.
[21:21:33] <andypugh> And enabling the 8i20 and powering it up should give you a good idea as to whether comms with te computer is working. Note that in that messgae you linked to, Visteurs was trying to use his own RS422 convertor, and it wasn't necessarily right.
[21:22:28] <ekacnet> I have a 7i52 but as the 8i20 is a bit costly I'm reluctant to use it without load
[21:22:52] <ekacnet> I fear frying the transistors
[21:23:58] <andypugh> Shouldn't be a problem.
[21:24:09] <andypugh> I have done it many times, for days on end.
[21:24:30] <ekacnet> ok good to know
[21:26:48] <ekacnet> I just didn't wanted to nominated to the next darwin award due to motor runaway
[21:33:25] <ekacnet> andypugh: one more question latest version of pncconf should handle the 8i20 ?
[21:33:38] <andypugh> I don't know. I have never used it.
[21:33:50] <ekacnet> or I need to get still inspiration from what I have found on internet
[21:35:07] <ekacnet> because currently pncconf didn't and so the generated hal has signal that are way different from the ones I could find on internet (ie. http://freeby.mesanet.com/hm2-servogreen.hal where a couple a hal components clearly name the 8i20 pins)
[21:38:43] <andypugh> What is Pncconf doing wrong then?

[22:33:36] <jthornton> how do you clear the buffer?
[22:33:42] <atom1> in your .py file i just downloaded, i had to change window to window1

[23:02:10] <jthornton> whatever that means The GLib Object System, or GObject, is a free software library providing a portable object system and transparent cross-language interoperability.
[23:03:43] <atom1> GObject is an abstraction layer that allows to program with an object
[23:03:43] <atom1> paradigm that is compatible with many languages. It is a part of Glib,

[23:09:25] <jthornton> some of the cryptic stuff takes time to understand what the heck it is doing
[23:11:10] <mhaberler> since the main loop is needed to handle the UI and its events, blocking calls like sleep() will block the UI as well, so everything goes through event handlers (aka callbacks)

[23:28:54] <andypugh> flat plate, three prongs, 6 ball bearings, just like a touch probe.
[23:29:19] <r00t4rd3d> image of one please?
[23:30:01] <andypugh> http://www.indoor.flyer.co.uk/probe.htm (upside down, without the stylus)
[23:30:09] <r00t4rd3d> i got 6 nice limit switches here, gonna use 4 on x,y
[23:31:52] <r00t4rd3d> i just want to accurately set my bit height, right now i just eyeball it to 0 on top of my material
[23:31:53] <atom1> http://www.youtube.com/watch?v=0jhyfDpt4hk
[23:32:39] <r00t4rd3d> i want to lower my bit onto something sitting on my material and the machine finds 0
[23:33:20] <atom1> use the tool table
[23:33:22] <r00t4rd3d> http://forums.zentoolworks.com/viewtopic.php?f=11&t=1968
[23:34:06] <atom1> use a chunk of pcb
[23:34:19] <r00t4rd3d> i have some
[23:34:38] <r00t4rd3d> i also have a old stop sign 1/8 thick
[23:34:51] <atom1> so subtract the thickness and store it in the z offset
[23:35:07] <atom1> copper is softer
[23:36:14] <r00t4rd3d> i just looked at the pcb i have and its through hole proto board
[23:36:32] <r00t4rd3d> so that wont work
[23:36:38] <andypugh> r00t4rd3d: Do what JT does (and I sometimes do). Lower the tool too far, slide a dowel up to the side if it, jog up until the dowel slips all the way in. Touch-off to dowel-thickness.
[23:37:08] <r00t4rd3d> to redneck
[23:37:22] <r00t4rd3d> i want to automate it
[23:37:47] <r00t4rd3d> with my brains and some electronic wizardry
[23:38:09] <atom1> you shouldn't be asking us then
[23:38:48] <r00t4rd3d> whys that
[23:39:04] <atom1> with your brains n all
[23:39:24] <r00t4rd3d> my brains accept input
[23:39:43] <atom1> i saw a nice one like andy suggested but i can't find it
[23:40:01] <r00t4rd3d> http://emergent.unpythonic.net/01216264526
[23:40:15] <r00t4rd3d> thats where i got the limit switch idea from
[23:41:31] <jdh> looks quick and easy.
[23:42:06] <r00t4rd3d> jepler, you ever do any thing with that?
[23:43:00] <r00t4rd3d> the post if from when they were all newbs
[23:44:57] <r00t4rd3d> http://forscience.nl/?p=144
[23:45:00] <r00t4rd3d> im doing that
[23:45:29] <jdh> doing what
[23:45:41] <r00t4rd3d> touch plate
[23:45:48] <r00t4rd3d> look at the for science link
[23:45:59] <jdh> Configuring LinuxCnc to accept my touch plate (also known as a touch-off plate) was not easy.
[23:46:06] <jdh> It's one line.
[23:46:15] <r00t4rd3d> he has step by step instructions on setting it up
[23:46:35] <atom1> it's just a line of code in your hal file

[23:54:41] <skunkworks__> i just used a simple microswitch.
[23:55:42] <skunkworks__> made a bunch of circuit boards with it - touch off first tool manually - it would then measure the first tool and then after each tool change it would measure and adjust the tl automagically
