When homing, the Y motor sometimes squeals like it is being driven at an extremely high feed rate, and homing fails.

If I power up the Pro Dual Extruder on my shelf, with 2.1.3.0.7, and immediately press Home All or Home Y it sometimes makes a high pitch squeal like the Y motor is being driven at way too high a feed rate. The Y axis either does not move, or moves a millimeter or two, and then it displays homing failure please reset. I duplicated this on a different Pro with single extruder Galaxy firmware. Both 2.1.3.0.7.

How often this happens seems to depend on the printer. The Pro on my shelf does it often, the one with Galaxy firmware does it far less often, and a third one I tried wouldn't do it at all after maybe 20 tries.

Once in a while the Pro on my shelf will squeal for a much longer time, a couple seconds, stop squealing, and the touch screen will be non-responsive. This has only happened on that Pro.
