G-Code, CAD, and CAM discussions / Cutter Compensation

« on: January 23, 2007, 09:13:06 AM »

I am trying to do cutter compensation on a fairly simple shape, but Mach 3 complains about the end radius of the arc not matching the start radius.
The GCode below works fine if I remove the G41. Any suggestions?
