The probe touches 4 points on the inside of the circle.
To compensate any ball-tip center offset, press the soft key to rotate
the touch probe by 180 degrees, and probe the 4 points on the inside
cylinder surface again. (This operation is possible only on machines
with spindle orientation, defined in MP6160).
No probing from opposite spindle orientations.
