Edge Probing

[Rypper]

Hello,

I have now gotten my probe connected and working.
and would like to do some edge(profile) probing with Mach3.
Is there a macro or wizard available for this function.

Thanks,
Tom

There is no macro avalable for this at this time at some point we will be building a wizard to help with this.

thanks

I've searched here and the Mach support forum and couldn't find any updated info on an edge probing wizard. Any progress?

I just purchased a touch probe for the purpose of edge probing only to discover that it (apparently) isn't possible with Mach.

I guess the main thing I need is a "XY arc probe" move and I can write the macro myself.

Thanks,

Steve

Gerry, that looks perfect! Thanks for the pointer.

Steve--Where you able to get the Razordance probing routines to work?
Thanks

No, unfortunately I never did not get the probing routines to work correctly.

I started doing some troubleshooting, but had to switch gears and never got back to it. I did get some basic movement, but it was very inconsistent. It appeared to me that the routines were not picking up my values - which could be an indication of a installation error.

At some point I will revisit this because probing is something I do need from time to time. I find it really hard to believe that there isn't any built-in support from Mach to do this in a reliable way. Ian has created some nice utilities, but there's no proper interface provided by Mach and it seems buggy at best.

Steve--Thanks for your feedback. Is there any way that you (or anyone) knows to give the probing routing the 2D coordinates from a dxf shape to follow when doing the 3D probing? I think in some or most cases the outside shape is known and just need to probe the 3D.
Looks like this would be a good addition to the digitizing wizard for Mach3.

Nelson, I *think* the Razordance package does allow specifying a 2d boundary around the part to be probed. There are people who have this working, so I don't know what is causing my problems. It would be worth giving it a try.

There is more info on the Mach discussion forum.

Steve--I had asked Ian about this and he said that currently his software doesn't allow for inputing the 2 axis perimeter.
Seems like a person should be able to use CAD to generate the outside shape, fill the inside with points spaced as desired and then generate a program using something like a G81 drill cycle in conjunction with G31 to create the "bed of nails" output.
Probably not that simple or someone would have done it by now.

Actually, I don't think it would be that hard. Basically read a .dxf of points and create a g-code file with a G31 for each point.

I create my g-code with an AutoCAD macro I wrote. This would be pretty simple to do in AutoCAD with VBA.

Gerry--Is this something we could twist your arm into doing for the rest of us "non-programmers"?
