I am in search of CAD/CAM software and have decided to investigate Mastercams capabilities. I recently rebuilt a Techno router and configured it to run on Mach2/3 from Artofsoft. I am wondering if Mastercam has a post for this controller? Also, I have used Alphacam for other machines which I rebuilt, and the post modifications are fairly easy. Is it easy to modify Mastercam posts and are there any manuals on how to modify post in Mastercam?
