This abrupt stopping of the rotary hook can cause it to slip a little on it's shaft. I noticed you had mentioned "material thickness" in one of your earlier posts. Am I to assume you are running a Non-XT Amaya with software from before 2006???? When was the last time you had a technician give the machine a "once over" to check all the fine points of the machine?
