The Commander core allows a combination of circular or arc interpolation of X and Y axes with linear interpolation of the Z-axis to provide a helical path of motion. The U axis is used in the background as a virtual axis to aid in the performance of this function.  This feature is used in applications that may require circular interpolation between the X and Y axes, and to adjust the angle of a jig toward an arc tangent point with the Z axis. Since the U axis plays a role in these moves, it cannot be used for any other purposes.
