Editing a Mastercam post processor is a valuable skill that moves you from a standard CAM user to a master of your manufacturing process. By understanding the .PST file's structure, mastering basic syntax, and learning to use the built-in tools, you can ensure that the code your software generates is perfectly optimized for your specific machine tools.
Mastercam posts support C-like logic, though the syntax is archaic.
Some edits are beyond a shop floor machinist: You generate the code, press cycle start, and walk away
Use a text editor like Notepad++, or better yet, a specialized post-editing tool like , which provides syntax highlighting. 3. Edit Variables (The Easy Way)
Before making any changes to a post processor file, follow these non-negotiable safety steps: Create a Backup : Always copy your existing
