New in Version 5.11

Cutter Compensation has been added to Advanced and Legacy MASSO CNC Controllers.

This feature allows the controller to automatically adjust the toolpath based on the programmed tool diameter and the actual tool size.

Use the same G-code program with different tools (with correct offsets).
Compensate for tool wear or regrinding by updating the tool diameter in the tool table.
Achieve higher precision without needing to regenerate CAM programs.
