Why not .005mm or .0025mm per step.
If THAT resolution is not swamped by the minimum imposed by the hardware - why not.
The question is - if you can acquire a resolution of .005mm or .0025mm per step - will you see it in the print?
You can definitely see print difference between a UM1 and it's competition --- so can the UM1 do any better if the micro-stepping on the motor can be increased?
Thanks.

IIRC the steppers on the UM are 200steps/rev -> 1.8degrees/step. With microstepping at 1/16 we're at 0.1125degress/step. I can't remember the diameter of the pullies but let's say they're 15mm in diameter, I think that's a reasonable guess. Each step would then move the outer part of the pully 0.01mm per step.
Unless I'm completely off with my calcs that sounds like pretty decent resolution to me. How much more are you looking to get?
