isn't that what the DRO is for.

Yup. The term "feedback" covers a lot of ground.

If you are using it for "full stroke" milling I guess a wiper motor
is useable. Certainly not if you are going to try to set it up as
CNC - which is more what I was thinking of when you mentioned power
driving the feed.

I wouldn't say CNC. Certainly the wiper motor stops dead when the
power is removed, well maybe not the armature, but the table does. I
can cut a slot within a tenth of a given distance. A caveat is to
take the backlash out before cutting or you end up cutting short.

Cutting short isn't as bad as cutting long!! You know the old saw -
"I cut it again and it's STILL too short"
