New tests with 125W motor, fitted with a 400PPR Avago encoder.
The Step/Dir signal is provided by PlanetCNC USB software and board.
You can see how servo parameters affect movement smoothness and so...
I managed to reach 1500 RPM with about 80% power (I am still waiting for a lab power source... soon to come... )
I think the movement got really smooth and precise. I will mount this to my new Z axis and see how it acts under some load conditions.

Enjoy the video.
