I have a unique situation. I have a full time job and do pottery as a hobby. I recently bought a wheel off of Facebook marketplace for $150. The only words on it are "intelligent ceramic drawing machine" definitely not a high tech wheel and only for beginners. It works great! The only thing is as soon as I press the pedal to bring power to the wheel a very loud beeping sound sounds continuously as long as the wheel is moving. I noticed the wires to the pedal have one that looks like it isn't connected but it makes this sound even when I don't use the pedals and I only use the manual speed butt
