Hi, I started having this problem a few days ago where my printer would make a loud whirring noise while homing its axis but restarting the printer and moving the x/y axis seemed to fix it and its been printing fine. However, this morning I have been getting the same whirring noise and haven’t been able to fix it.

As far as I can tell the motors and end stops are all functioning correctly and the noise happens even before the axis reach their end stops. The noise doesn’t stop until I switch the printer off. Here is a video of the problem: Monoprice select mini whirring sound - YouTube The sound appears to be coming from the base of the printer.

Thanks for the help!
