For 3D toolpaths, Mastercam often breaks code into subprograms. The Siemens post must output LBL and LBLxx structures correctly.
If you have MP post processor experience, you can edit the .PST file. Critical sections to modify: siemens 828d post processor for mastercam
Developing a post for Mastercam to the 828D requires attention to several critical areas: For 3D toolpaths, Mastercam often breaks code into
Standard posts output long-hand G81, G83, etc. A proper 828D post converts these into Siemens CYCLE81 (Drilling), CYCLE83 (Deep hole pecking), and CYCLE84 (Tapping). This reduces line count from hundreds to a few lines and allows operators to edit parameters directly on the 828D panel. For 3D toolpaths
