In profile mode Mach cuts corners off? Shortest distance issue?

Edit: Oh and your G-code doesn't help matters by creating arcs with tiny lines. Try using a post processor that uses (i) (j) Arc moves instead of breaking each arc into tiny straight lines. Could also be a setting in the Cam software.?

Aspire has an option to simplify the vectors you are intending to cut. I think it is called "smooth" or some such. you can change the setting in that option to make the number of line segments less. Gives you machine a much easier time. You will hear the difference from the sound of the axis motors.
