Backing the y-axis off from the limit position (by manually turning the y-motion knob) caused the motorized Y-motion to be restored. There may be a problem with the range of motion allowed in the Y-axis .... but to investigate that requires pulling the entire probe station out onto a table and turning it upside down to get at the electrical limit switches. At this point, a single report doesn't likely warrant that unless one or more users of this tool required greater than +/- 1" (approximately) excursions in the Y-axis. If so, I will schedule the time to look into that.
