G90G10L2P0 (common coordinates) X0Y0Z0
Write G90G10L2P0 in the program and the coordinate value after it will be automatically entered into the corresponding coordinate system. For example: G90G10 L2P1(G54)X50Y10Z0:
X50Y10Z0 at the end of the program, after CNC reads this sentence, the G54 coordinate will be X50Y10Z0:
