JWC came into lab to evaluate the X stepper motor on the stage.  Initially obs. E4 and after moving the X axis to X = 150 mm manually I was able to get it to rehome towards X = 0 again.
Suspect wear or binding n the X worm drive that caused excessive current draw resulting in error on the Stage controller.
