4.12.2 G29: Return from Reference Position
Format:
G29 [G00/G01] X_Y_Z_A_ (M84)
G29 [G00] X_Y_Z_A_B_C_ (M86)
G29 [G01] Six-axis four-axis combination (M86)
G29 [G00/G01] X_Y_Z_A_B_C_ (M86R)
The coordinates in the G29 command format refer to the coordinates of the destination point of the tool. This command allows the tool to pass from the first reference point through the halfway point to the destination point. This ensures that the tool can reach the point of interest to be machined via this safe path. The waypoint is the point specified in the G28 command. Before using the G29 command, the G28 command must be used to prevent the G29 from not knowing the position of the intermediate point and causing an error.
