| Feature | What to check | | :--- | :--- | | | .pst (the logic file) and possibly .psb (encrypted binary). No .exe , .scr , or .bat . | | Header Comments | Open the .pst in a text editor (Notepad++). The first 50 lines should list the developer, date, and machine target. | | Machine Definition Match | The post must pair with a .mmd (Machine Definition) and .control file. A post alone is only half the solution. | | Test in Backplot & Verify | Use Mastercam's Backplot and Machine Simulation with a simple part (drill one hole, cut one square). Inspect every line of G-code. | | Air Cutting First | Run the code 4 inches above your part. If it looks right, step down. | | Single Block & Low Feed | Never run a new post in full auto mode. Use Single Block, 5% rapid override, and watch the distance-to-go. |
