Just got my M2 assembled and calibrated. The big issue for me is the constant whining noise that motors make ALL the time. Primarily the X and Y motors. The noise starts as soon as I plug in USB cord to a computer. It gets a bit quieter for 1 second or so after “Set Home” is pressed in CNCjs/Makerverse but it is there unless power is cut to the board.
I tried several different Due boards with same shield but there is no change.
That high pitched noise is unbearable to me and makes me keep the machine off until the last minute before I have to use it and turn power off as soon as I’m done.
Please help me keep my sanity in shop. Any ideas on how to make M2 be quiet when it’s not in use?
