I'm currently enrolled in an Industrial Maintenance class and am working through CNC Operation. The big issue with that is the CNC not responding to the workpiece zero.
The machine, a Levil WL-F400, has a Fanuc Series Oi Mate-MD controller. Going through the lesson, it has me set G55 as the workpiece zero using an edgefinder, and the X and Y zeros work properly. The issue with the Z axis. Despite setting the Z axis for G55, the machine sets the Z axis for way lower when actually running. The same code that will position it right above the corner of the workpiece will also cause it to overrun on Z.
