When defining MCO for turret movement in part CS (G54), tool tip is moving from position in last operation, to absolute coordinates in G54.
Picture NZF-534-40546
If coord. systems of sub-machine, vMAC, and G54 are in same orientation, then xh_move, yh_move and zh_move will have same values. If they are not in same orientation, they will have minus (-) values.
