If you don't know why a post is skipping a line, force it to stop. Insert this debug code into the line you are testing: "M00 (DEBUG: Coolant turned on here)", e$ When your machine runs, it will stop, and you can see if the code appeared before or after your motion.

Once you are comfortable with swapping strings, you need to understand MP logic. It resembles a hybrid of C and BASIC. Post-Processor: Definition, How it Works, and Uses -

These define how numbers are formatted (e.g., decimal places, leading/trailing zeros).

if toolchng = 1, [ pbld, n$, "M01", e$ pbld, n$, "G28", "Z0.", e$ ] else, pbld, n$, "G00", "Z.1", e$ Insert this debug code into the line you

For those looking to master this skill, specialized training programs cover Fanuc, Haas, and Siemens logic, teaching users how to build IF/WHILE loops and math-driven cycles into their posts.

If you’ve been in CNC machining for more than a week, you’ve likely heard the phrase: “It’s just a post thing.”

In the world of Computer-Aided Manufacturing (CAM), Mastercam holds a throne as one of the most powerful and widely used software platforms. However, generating a toolpath is only half the battle. The true magic—or nightmare—begins when you need to convert that toolpath into G-code that your specific CNC machine understands.
