1. An apparatus for controlling an electric stepping axis motor wherein the said electric stepping axis motor responds to a plurality of different control settings corresponding to binary words of a predetermined set of binary data, said apparatus including:

  • a memory containing a file for storing a plurality of said binary data;

    a pulse source for issuing each of said plurality of binary words from said memory at predetermined evenly spaced time intervals;

    an interface for decoding said binary words from said memory and controlling said electric stepping axis motor in accordance with the control settings corresponding to said binary words;

    a manually actuable joystick unit for selecting control setting commands consistent with desired speed and direction of said electric stepping axis motor, said joystick unit including a feedback stepper motor for interacting mechanically within said joystick unit to cancel previous control setting commands, said feedback stepper motor including;

    control wiring coupling said feedback stepper motor to rotate in unison with said electric stepping axis motor;

    an encoder for encoding said control setting commands into binary words at evenly spaced time intervals; and

    switching means for saving said binary words to said file in said memory at said evenly spaced time intervals.
