I looked and sure enough the steel leaf of the switch was twisted downward. I was able to jog the head left while holding the limit switch down so I assume the unit needs to be replaced. Do you know if there are any spares at sudo? I have some from open source hardware that look similar but didn't want to attempt taking off the rail to get at it and making it worse. Cheers, Hol
