CNC coil winder traverse

I have been collecting parts for a CNC air coil winder for a long
time now and have come to the part that has been stopping me, the
wire traverse.

I am using very thin wire down to 0.02mm and want to wind as
accurately as I can, preferably perfect wound coils. To do this and
to make the coils I want to make, at the speed I want to do it, I
guess I need a system accurate to perhaps 0.01mm (half the wire
width) or perhaps less and capable of say 10mm/second traverse.

I had originally assumed a stepper motor system with a fine ballscrew
but for the price I don't think I will get the accuracy I desire.

What I am contemplating is a servo system using a Geckodrive, a small
servo motor, an IKO rail (which I have) and a belt drive. The
feedback to the servo would be via a short linear encoder.

Questions:

1. Does this seem feasible?

2. Any suggestions for sources of small servomotors?

3. Any issues with driving small servos with a Gecko?

4. Will a belt drive be good enough in terms of backlash, I guess yes.

5. Suggestions for the encoder, sources, lines per inch whatever


The load will be low as it will be a simple wire guide, this machine
will be optimised for thin wire.
