Re: [CAD_CAM_EDM_DRO] Re: Treadmill motors as Servos

I'm not too knowledgeable about treadmill motors, but from what I've heard,
this is not do-able. The reason is that the brushes on a treadmill motor
come in to the commutator at a slant, or offset, rather then straight in,
and thus will work well, but in only one direction, not both.
