I might be missing something but why would you use a belt drive with a 1:1 ratio. The motors will hang to the side and then out front anyway. In addition you will need to take care of radial as well as axial loads with the bearing arrangment. Seems like a lot of work for zero gain to me.

Hawkjet, I think that doing a 1:1 I will not need to be concerned with the resolution/accuracy issue that you mention. Correct me if I am wrong.
