Not a problem from the development or "play" viewpoint. I suspect
that once you get it working and actually use it that you will only
want the .002 and .001.

The Stick-Slip on the ways and stepper granularity will be a problem
with small increments. You will turn the knob and nothing will
happen for a while every time you change direction (backlash).

For larger distances you will probably want to use the controller jog
and push in a button.

Are you doing anything with % Feed rate override? Have you given it
any thought? Some of the controller software has this built in as a
key press adjustment during program operation, some doesn't seem to
have any provisions to adjust the feed while the program is running.
