I have a script installed in Mach3 that is called by the "Auto tool zero" button on the Program Run page (in the Tool Information box in the standard 1024.set screen layout) that I would like to assign to one of the function buttons on my VistaCNC PS-2 pendant. I found the script attached to a Youtube video that went through the details of how to install it and get it running, which I followed no problem. I just haven't managed to find the right documentation that describes how I can take that function and apply it to the pendant...doesn't seem to be in any of the places I'd expect either at ArtSoft or VistaCNC. I figured with all the knowledge floating around here coming up with someone that's done this already (or at least knows how) would be the best way to find out how to get it done. Any help would be greatly appreciated... TIA <marv>
