General Mach Discussion / Re: edge finding/2.5D probing
« on: November 21, 2007, 01:03:52 PM »
Terry, just tried it with a few delays and thus far no luck - I'll try some more experimenting tomorrow. BUT - how's this for wierd?

I just noticed that it fails to work in a pattern. I went back to Art's wizard and set it to probe 100mm in the X and 50mm in the Y with a stepover of 5mm. It turns out that whenever X is 0 or 5 or between 95 and 175 it works fine, any other value of X i.e. between 10-90 and 180-200 and it doesn't. i.e. it fails in "stripes" in the Y direction. Regular as clockwork  ???

Tomorrow I'm going to probe my whole table and I'm betting it spells something out - like playing a sabbath album backwards ;D

Hi Mike - yeah sorry didn't explain things too well. I'm assuming you've:
1) renamed the file I sent as probe.zip
2) unzipped it
3) run setup.exe
4) copied the gcode file and the macro as instructed

now please have a look at the attached (word) doc.

TP - Re: your g4p0 trick - is that for use in VB as in after a "code G31..." or in a .tap or both? I tried it in a .tap and no difference.

G1 Z10
G1 X10 Y10
G31 Z0
G4 P0

Still crashed down to zero even though the object probed was at Z5 - strangely it records the point correctly - just doesn't ****ing stop! and crunch AGAIN!

So can you actually run a bed o nails routine and have it work ok? - I've never got one to work properly yet!... whether I use Art's wizard or Art and Brian's plugin. every time - crunch - I've tried versions of Mach from 1.84 to 2.6. - all the same.

Hi Mike - this could get frustrating what with the time difference...

You could just run the g-code but it'd be better to run the app from your start menu first. By default all the settings are in mm so you might get a few surprises - like a feedrate of 3000 for instance.  :o So....

Run the app, set up your choice of params, run probe25D.tap. The probe will move to startX,startY at a height of safeZ then drop to probe@Z and then travel Y+ve till it hits your edge, it'll then wander round the edge putting points in your triple file. Note that you need to move/delete/rename the triple file each run because it's appended to - not re-written. BTW double-clicking on a file text box will bring up the open/save dialogs. Must write some destructions for it all ;D

Also - could you send Terry a copy of the zip - I'm having trouble getting it through...

General Mach Discussion / problems with G31 Z and bed o' nails type probing
« on: November 20, 2007, 05:38:00 AM »
Like with Art's wizard or Art and Brian's plugin (or anything else that uses G31 Z). Anyone come accross feedrate randomly changing and G31 Z crunching your probe after ignoring it touched on the way down? Seems to come and go at random, but both happen together.

I'm pretty sure this didn't happen pre 2.56 but I may be wrong.

Hi TP, No problem - as I said to Mike, drop me a PM with how I can get them to you (a 1.5 Meg zip) and we'll take it from there.

BTW Mike I took the .zip extension off and mail hasn't bounced it this time so hopefully you have it by now.

Cheers

Hi Mike - sorry for the delay in replying.

I havn't wanted to post the routines until they were tidyer and easier to use because I've fallen foul of releasing software too early before - it just leads to grief and a lot of running round in circles - mainly for me ;D

Anyway I now have a bundle that you're welcome to try. I don't want to post it publicly yet until they've been "beta"'d by at least one person - and you seem to have volunteered yourself  :D. Drop me a PM with how I can get them to you (a 1.5 Meg zip) and we'll take it from there.

Cheers

Hi Mike

Sorry - been off the case for a while - too much to do too little time  :'(. Hopefully I'll have something usable to post in a couple of days.

Cheers

I posted this http://www.machsupport.com/forum/index.php/topic,4694.0.html a few days ago but thus far have had no comments. I've had this happen a couple of times and the only way I've been able to resolve it is to re-install mach - it works for a while and then...
This seems to have become a feature since 2.56.1 which maybe coincidentally was the CV fix version after this thread http://www.machsupport.com/forum/index.php/topic,4113.0.html
