ABSTRACT:
A method and system for calibrating a machine capable of automatically calibrating the axes of the machine by comparing an initial calibration state of a particular axis with a subsequent motion of the machine along the same axis. The machine adjusts the motion along such axis based on the angular displacement by modifying the reference data in the computer memory of the machine to accord with the subsequent motion along the axis.
