Hi, I have an artisan 3200 with a servo motor, went to sew some skirts together today and sewed a test piece first, pulled it out, cut the thread and the machine started going on its own, without me touching the foot pedal, i turned it off then back on and the caution light came on. I've tried unplugging it and waiting but it wont go out and the machine wont work. Is the motor cooked? Its only a couple years old and hasnt seen too much use and zero abuse. Any help would be much appreciated. Just sold my trusty back up Mach 3, now wishing I still had it
