[GrizHFMinimill] Re: static sounds coming from motor

Do the sounds happen when The motor isn't turning? If so,mine has done that occasionally since it was new. It seems to happen When he speed control is powered up but the motor is powered off.I always considered it leakage from the speed control.Other than that I have not had any problem with the mill in the 12 years I've had it.
