Comments in Code

Comments in code allow you to add notes and documentation to your CNC program without affecting the simulation.

Example of comments in CNC code

2.8.1 Two Comment Methods

Parentheses Comments

The primary approach involves placing comments within parentheses. CNC codes inside the parentheses will be ignored by the CNC Simulator Pro interpreter.

G00 X0 Y0 (Rapid move to origin)
G01 Z-5 F100 (Plunge cut)
Parentheses comments
Comments added using parentheses

Note: CNC Simulator Pro-specific $-commands will still be processed even when inside parentheses.

Semicolon Comments

An alternative method uses semicolons, which is commonly used to comment out whole sections of blocks.
