I am out on a limb here as I dont know anything about the 5 PRO, but a similar issue came up on a 5 Pro awhile back and the OP indicated it was a problem with one of the Y limit switches. I also don’t pretend to understand how one of two Y limit switches caused it. Here is the thread: Not sure where I'm going wrong here - Juice groove. Maybe this will jog some more knowledgeable forum members memories, who can elaborate if this could be a cause. Cheers
