I have customer owns a machine shop. He has an expensive Optical Comparator (OC) that has some bad XYZ stepper motor control problems. He asked me if I could come up with a control unit that would run his OC. I will post a picture of the pendant that I made for him. It has some nice features in that it plugs directly into the G540 (not included). It has a XYZ slector switch for selecting the desired axis. It has a mode select switch to select fine movement with the encoder or use with the internal pulse generator for rapid movement. Use the speed control pot to vary the speed. Each axis direction is is reversable. Simply select the mode
I see that this could be used with Mill-Drills as a selectable XYZ control unit where cnc is not required. It plugs in directly to a Geck G540 control box.
