Title: Weird difference between CutViewer and Mach3
Post by: frasej on June 11, 2013, 03:55:20 PM

I just created some gcode to cut a wall switch/outlet cover.  When I view the output of the gcode in CutViewer, it's perfect.  When I bring it into Mach 3, the "I" commands cause a huge circle to be cut.
Sorry for the length of this.
