I am new to the CNC world but I do have a lot of experience in Catia design. I've always wanted a CNC router so last year I built one. I have Catia Prismatic machining and my CNC uses Mach3. I have very little knowledge of the prismatic desktop and am trying to understand the method of exporting the code that the Mach3 uses. It appears that the Catia generates APT,CLF or NC codes. The Mach3 will only import .tap, .nc, .ncc or .txt formats. Can anyone give me some advise on getting from the PM to Mach3?
