MANUALplus automatically determines the cutting and infeed
directions from the current tool position relative to the starting
point / end point of the contour area.
Tool position at the end of the cycle:
G827: Cycle starting point X; last retraction diameter in Z
G828: Cycle starting point
Example: G827, 828
