Switching over the coordinate system (MCS/WCS)

The coordinates in the actual value display are relative to either the machine coordinate
system or the workpiece coordinate system.
By default, the workpiece coordinate system is set as a reference for the actual value
display.
The machine coordinate system (MCS), in contrast to the workpiece coordinate system
(WCS), does not take into account any work offsets, tool offsets and coordinate rotation.
Proceed as follows

Switching the unit of measurement

You can set millimeters or inches as the unit of measurement. Switching the unit of
measurement always applies to the entire machine. All required information is automatically
converted to the new unit of measurement, for example:
