If your edited post outputs unexpected G-code or generates syntax errors, Mastercam provides native tools to track down the root cause. Utilizing the Bug Tracker ( bug2$ )

Compare the new G-code against an old, verified working file using a text-diff tool (e.g., Beyond Compare).

Variables and logic that define how Mastercam interprets the toolpath (e.g., feed_rate , spindle_speed ). C. Motion Blocks Sections that govern tool movement: prapid : Rapid moves ( plin : Linear interpolation ( pcirc : Circular interpolation ( D.
