RE: [CAD_CAM_EDM_DRO] Re: tach output

From what Mariss (The Gecko King) has posted, no the drives will not
function correctly with linear encoders. The concern is that the encoder
will not be coupled to the encoder tightly enough and the servo loop
will not be stable. It may work in some cases if you have a VERY tight
setup with virtually no backlash, but that is not what you are
describing.
