Putting encoders on a stepper is an obvious idea that occurs to everyone
faced with positioning errors, but it turns out th

Yes, of course it can. You need a way to read the encoders into the PC.

There are stepper drivers that can extract feedback for
detecting missing steps, but they require parameters be
set to match the particular motor. One such device is

Mariss Freimanis of Gecko did quite a bit of work on this a while ago,
called the
"unstallable stepper", I think. There should still be some info on the
