Today the wash stopped again at the same spot.☹
I'll investigate and keep you updated...
Where is your distributor during this? Was a tech the one who tightened the belts?
What is the plc error code? Did you ever investigate the simultaneous input signals on you input cards? I believe they were gantry home and gantry rear limit / front limit all lit; this, in my experience, is illogical and indicates a malfunction of prox / cable / relay/cable end.
