General Mach Discussion / Problem using G41 (tool diameter offset) and G68 (Rotated Coordinate System)
« on: March 04, 2016, 05:52:33 PM »
Hello All, I'm hoping someone more knowledgeable than I can help with how to implement both G41 and G68 at the same time in Mach3. If the "Local System Rotated" is set to 0 in the MDI screen then the G41 (and accompanying lead in) work fine (pic attached). Without the G41 command in the gcode the "Local System Rotated" works fine. But when I use both the tool path gets goofy (pic attached). I've tried outputting as both line segs and arcs but neither way works (gcode attached).
I need to use G68 because I have to optically align to fiducial marks embedded in a substrate. I want to use G41 because the size of that substrate changes and I don't want to have to make a new gcode file in our CAM software for each one but rather want to just use the scale feature in Mach3. I would really appreciate any help. Thank you very much
