Mounting motor under table?

Ermm. . . Not a good idea IMO realying on micro stepping.

I'm not saying rely on it, just it might help. Clearly the result will be slightly distorted.

I already mentioned about microstepping accuracy (or rather lack of) in post #15...

One thing I'm going to try and do with my stepper driver design is make it effectively run using microstepping, for smoothness, yet only require the number of pulses for whatever microstep division you choose. Effectively it will move through each of the microsteps for every step pulse.

ye I know Jonathan and wasn't really picking up or discrediting your referance about microstepping more pointing out for high resolution operations like engraving etc then it's better to use the correct pitch screw.
