#emc | Logs for 2009-10-03

[00:00:47] <cradek> are you saying that emc1 would add an entry to the tool table when you did something in the gui?
[00:01:39] <cradek> what version of emc2 do you have? I'm not aware of any EMC2 packages made for BDI in the last 3? years
[00:01:57] <sed_> yea, the tools file when you click edit tools, it would change/add the value to that file
[00:02:22] <sed_> (all 2's anyway)
[00:02:25] <cradek> oh it would let you edit the file directly
[00:03:08] <cradek> 2.2.2 was released in late 2007
[00:03:10] <sed_> yea view-tools
[00:03:22] <sed_> brings up the file for edit
[00:03:41] <sed_> but that file does not change if you click on offset and add/set a tool
[00:03:45] <sed_> like emc1 did
[00:03:53] <cradek> what do you mean click an offset?
[00:04:35] <sed_> on tkemc there is a box that says Offset: ____ you click on that and it brings up a box you can add a tool number and offset
[00:04:53] <cradek> oh, interesting
[00:05:09] <sed_> got used to setting it there in emc1
[00:05:10] <cradek> you should try emc2.3 which may have inadvertently fixed that
[00:05:39] <sed_> ok will try, is the upgrade to 2.3 very streight forward after we have tuned everything and so forth?
[00:05:42] <cradek> in emc2.3 there are smart ways to touch off tools - the tool touch off dialog in AXIS (if you start using AXIS) and also a gcode command
[00:06:07] <cradek> sed_: if you are using BDI I have no idea. If using Ubuntu, it is very easy, and we have instructions written up.
[00:06:37] <sed_> its ubuntu, sorr bdi was a misquote
[00:06:40] <cradek> for BDI you will have to compile it yourself, and I don't know how hard or easy that is on BDI nowadays.
[00:06:43] <cradek> oh ok.
[00:06:45] <cradek> let me find you the url.
[00:06:53] <sed_> thank you
[00:07:03] <cradek> well go to the front page of the wiki http://wiki.linuxcnc.org/
[00:07:12] <cradek> it's about the second link on the front page
[00:07:38] <cradek> you can also see the billion new features and bugfixes since then
[00:07:43] <andypugh> cradek: I might well get to try your threading improvements this weekend. I won't be doing any machining.
[00:08:17] <sed_> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.3
[00:08:19] <cradek> very few changes to tkemc though... it is not actively maintained currently.
[00:08:20] <sed_> cool thanks
[00:09:22] <cradek> andypugh: I should probably try that patch on mine too - it's a very different machine and would be a good data point
[00:09:34] <cradek> I'll try to do that this weekend sometime, but I have a busy weekend planned.
[00:09:55] <sed_> cool thanks for your help
[00:10:00] <cradek> welcome
[00:10:03] <andypugh> I had a busy weekend planned, but blew up to of my stepper drivers. It has turned quiet.
[00:10:13] <cradek> two??
[00:10:18] <andypugh> Yes,
[00:10:23] <cradek> ouch
[00:10:25] <andypugh> the second one is a mystery
[00:10:44] <cradek> is your wiring neat, or is there bare stuff?
[00:10:51] <sed_> what about Keystick is that maintained?
[00:11:02] <cradek> sed_: no
[00:11:20] <cradek> sed_: only AXIS has seen much work in the last year or two
[00:11:27] <andypugh> I was editing the .hal file with the machine powered up but not moving, when the Z motor went quiet, and then there was a "pop" from the controller box.
[00:11:29] <cradek> there are new features that are only available in AXIS
[00:11:57] <andypugh> My wiring is untidy, but insulated.
[00:12:03] <sed_> I dont have the balls on my computer for Axis... well only tried with gnome running.. maybe I will try with blackbox
[00:12:14] <sed_> cradek, features such as??
[00:12:22] <sed_> added to AXIS that is
[00:13:38] <cradek> touch off, tool touch off, radius/diameter mode for lathes, non-sequential joints/axes, ... who knows all
[00:14:08] <cradek> you can look through that stuff on the Released page and see a lot of things marked AXIS:
[00:14:40] <cradek> oh max velocity slider! that's the best feature ever
[00:14:54] <cradek> recently-used files on the file menu...
[00:15:35] <cradek> per-axis DTG
[00:16:18] <cradek> wow 2.2.2 is a long time ago
[00:16:20] <cradek> time flies
[00:17:41] <andypugh> My wiring : http://imagebin.ca/view/T0mlgK.html
[00:18:42] <andypugh> I suppose I _could_ have bundled it all up neatly, but it is bound to change.
[00:20:30] <cradek> well it's not a beauty contest but I know from sad experience that bare wires cause drivers to blow up - just asking.
[00:21:26] <cradek> CB microphone plugs for steppers? neat.
[00:21:34] <andypugh> No, bare wires are anathema. I even went to the trouble to find extra specially small fork crimps for the signal wires. (there is a small yellow size)
[00:23:01] <andypugh> I wanted to use Lemo connectors but I couldn't figure out how to connect flex conduit to them. I bore out those multiway connectors, bond in a sleeve and crimp to the conduit.
[00:23:53] <andypugh> (Actualy, they are only crimped at the motor end, as crimping at the plug end makes disassembly impossible
[00:25:06] <AchiestDragon> well at least you stand a chance of tracing the fault
[00:26:36] <AchiestDragon> http://www.whipy.demon.co.uk/dscf1918.jpg
[00:26:40] <andypugh> The first fault was a missing insulation sleeve in the plug.
[00:27:10] <andypugh> OOh, lovely, Verowire without the combs?
[00:27:30] <AchiestDragon> dual 68040 cpu card
[00:28:24] <andypugh> Did it work?
[00:29:13] <AchiestDragon> any faster than 40 mhz and the pickup on the wires wont handle the speed
[00:29:31] <andypugh> I was thinking that might the the limiting factor
[00:30:24] <AchiestDragon> theres another 3 boards part of the same system ,, a ram /flash , and 2 i/o bords
[00:30:34] <AchiestDragon> all as bad as that
[00:31:07] <AchiestDragon> its why i need a cnc to mill out pcbs on rather than having to do that sort of thing
[00:31:14] <The_Ball_> AchiestDragon, neat, I like it
[00:31:29] <andypugh> Why not etch them?
[00:31:52] <The_Ball_> * The_Ball_ is glad his etching days are over
[00:32:14] <AchiestDragon> etching is a bit limited on the spacings doing home etch and dont want the chemicals arround
[00:32:18] <andypugh> The vero-board in my system transmuted into a proper PCB. I drew it with felt-tip using a flatbed plotter, then etched it in the sink.
[00:33:58] <AchiestDragon> yea , feric cloride makes a real mess of stainless steel and crome ,,, you end up with a brown crome plug hole that does not ever clean , just rinseing the bords after etching
[00:34:06] <andypugh> I did drill the holes with the CNC though. http://www.youtube.com/watch?v=95B8PDlnajk
[00:34:36] <andypugh> Rented house, I moved out :-)
[00:35:44] <The_Ball_> andypugh, nice one
[00:36:08] <andypugh> Actually, it was a pretty much ruined plastic sink, and it didn't seem to suffer unduly.
[00:37:43] <AchiestDragon> you can get away with a cutting feed rate close to the travel rate your using there for doing the drilling on the pcbs ,, the machine i used at work for drilling pcbs although manual activated would drill a stack of 6 boards at the same time
[00:38:48] <AchiestDragon> only thing to watch is dont try drilling a hole twice or widening it with a slightly bigger bit or it will just snap the bit
[00:39:17] <andypugh> I thought I could probably go faster, but it wasn't like 10 minutes was that important, and there was no way to get a new drill bit in less than 3 days
[00:41:21] <andypugh> Anyway, time to sleep. Well, try anyway. Not much luck on that score so far this week.
[00:41:34] <AchiestDragon> well at last ,,, got to be at least 4 years since i last tried emc ,,, but now hoave emc2 running on a pc
[00:42:31] <andypugh> I suspect it has moved on in that time.
[01:10:25] <AchiestDragon> hmm will have a better play with it tomorrow
[01:10:34] <AchiestDragon> bed now ,, nn
