How to Edit Fanuc 8000 & 9000 Programs
Overview
By default, 8000 and 9000 programs are protected and cannot be edited. Enabling a parameter is required to edit 8000 and 9000 programs.
It is absolutely critical you know what you are doing when working with 8000 and 9000 programs. Changing or deleting a protected program can render the CNC machine inoperable and may require a qualified machine technician to repair it.
