* indicates optionalProgrammable mirror imaging is used to turn on or off any of the axes. When one is ON, axis motion may be mirrored (or reversed) around the work zero point. These G codes should be used in a command block without any other G codes. They do not cause any Axis motion. The bottom of the screen indicates when an axis is mirrored. Also see Settings 45, 46, 47, 48, 80, and 250 for mirror imaging.The format for turning Mirror Image on and off is:
G101 X0. (turns on mirror imaging for the X-Axis) ;
G100 X0. (turns off mirror imaging for the X-Axis) ;
X-Y Mirror Image


Mirror Image and Cutter CompensationTurning on Mirror Image for only one of the X or Y axes causes the cutter to move along the opposite side of a cut. The control automatically switches the cutter compensation direction (G41, G42) and reverses the circular motion commands (G02, G03) as needed.When milling a shape with XY motions, turning on Mirror Image for just one of the X or Y axes changes climb milling (G41) to conventional milling (G42) and/or conventional milling to climb milling. As a result, the type of cut or finish may not be what was desired. Mirror imaging of both X and Y eliminates this problem.Mirror Image and Pocket Milling
