RETRACT/nnn.nnnn
nnn.nnnn represents a number value for the distance. This command determines the distance the machine will move away from the actual hit location before going from "Touch Speed" to "Move Speed".
Some controllers do not retract on their own. In these cases, PC-DMIS issues the move to do the retract, and the distance is based on ball surface to the part's theoretical hit location. If the controller does do the retract, the distance may be calculated either from the ball surface or the ball center to either the theoretical or measured hit location, depending on the particular controller.
