support for touch probes
« on: November 21, 2009, 09:56:29 PM »
I'm looking for software support hardware touch probes.  I would like software and/or screens that will use the probe to set up the machine to get ready run a job.  Things like determining the zero point for the work piece, determining the height of the work piece, seeing if it is at an angle, etc.  Also, things like finding the center of a hole or the center of a round work piece.  I did a search on this site and got lots of hits, but I couldn't tell if any of them did what I was looking for.  Can anyone point me in the right direction?
Thanks,
Mark

There was a plugin that worked very well but it doesnt seem to be available anymore and nobody seems to respond about it.

Well, that seems to have killed the thread completely >:(  Come on, guys.  Are you telling me that nobody else has written anything that supports touch probes under Mach3?  Or maybe everybody that has is making tons of money with it and doesn't want to lose it. 
Touch probes are such a popular topic these days that I find it hard to believe that some of our resident mentors haven't done something to get one going.  And I haven't even mentioned a tool height setting probe.

Please, friends, help us newbies out.
Thanks for all your help in the past and that hopefully yet to come.

Have you looked in the downloads tab, plug-ins?  How about when you open Mach, wizards tab at top, digitizing wizard?  Member zarzul sells a touch probe in the bargin basement for $99 I think. There are a ton of custom auto zero scripts floating around. You can make one to do what ever you want if you can't find one that does already.

The offsets page in the standard 1024 set has many of the things your looking for I think, just need to write you some macros to use for a touch probe rather than an edge finder.

Look in the members docs board. I posted some info on a simple touch plate there.

Helo,

I'm new on this forum and a have some questions about de digitize probe.
-Can i mount the probe not in the center of the spindle?
-Can i take the probe for surfacing the plate, because the thickness of plexi isn't the same everywhere. when this is possible i don't need a floating spindle for engraving the plate.

Thanks

The probe can be mounted anywhere on the machine, you will have to know where it is in relation to the spindle so you know how much to offset the x,y positions by.

You can write your own commands into the g-code to take measurements at known points to do this you can use the G31 command.

G31 z-10 f25. will move the z axis minus 10mm unless it senses the probe touch something. At the touch point it stops and you can take a reading and do what ever you want with the data by calling a M code.

Thanks Graham,

I have also another question. When i use also other specifacly engraving software, is it possible to send a g-code(dnc file)file to mach 3 and that mach 3 its see so that i just have to start without loading the file?

No, Mach3 has to have a file loaded into memory, Mach3 has no limit on file size.
