Those sound like vexta stepper motors. I would replace them with motors you know the specs on. Also, they might be miswired unipolar motors that are being run with too much current. You better get some current limiting resistors on those babies, pronto! You don't need the most powerful motors for that machine. I would check out eBay for replacements.Originally Posted by jonboyusmc
Can you send a picture of the machine, I think I might have used one like it when I taught at my old school.
