dimensions. Traverse paths and position values are referenced to the
slide reference point – machine zero point.
Activating zero-point shifts G980
G980 activates the workpiece zero point and all zero-point shifts.
Traverse paths and position values are referenced to the distance of
the tool tip to the workpiece zero point, while taking the zero point
shifts into consideration.
