Hi Bill,
I am using KeyCreator 7 and am trying to get the NC to work with Mach3. I have hacked around a bit with the post templates and have attempted to modify one for use with Mach3. I can get it to look pretty close to the g-code examples included with Mach3, but I am still getting some errors with circle interpolation. Would you mind sharing the post processor that you created for Mach3?
