QUITE happy with motor changes

johnridleyWith the wiring change, the X and Y axes both went from being able to stall the motor with slight pressure from one finger to being able to move the entire printer around if I try to hold them steady.
The only odd thing is that the motors now emit this weird hissing noise when they're on certain phases of the PWM microstepping. Changing the drive current affects the noise. And they're running kind of hot (67 degrees) but that's pretty normal for these printers.
I may not even bother changing the motors when they come in, unless I actually have a problem.
