I know back Mastercam version 7 has natrive mazatrol post processor, unforturnate I started with version 8 and it is an option.
Anyway, Mazatrol post is an option and expensive, so I like see native mazatrol post for Mastercam? Don't you mind post the first 1/3 of the post(doesn't matter what version) I like to see what it is look like, I might gain something.
The best way to learn is trial error.
