Its a 3rd party thing I got on ebay but seems to work fine. I don’t think the sounds is coming from the motors, it seems like there is some sort of vibration somewhere in the machine. The only noise/vibration is when the machine is moving under 500 mm/minutes. If its fast or stationary there are no sounds. The motors don’t seem to be getting even warm, this issue happens even if I just turned things on. I will have to double check all of the bolts to make sure something isn’t loose somewhere.
