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 :)
