I have done a proof of concept modifying some of the available code and writing some new one so each servo motor mimics the motion of a stepper and reacts to the step and direction signals of Marlin firmware. For the moment only X and Y axis are changed: [www.youtube.com]

Parts for i3: [www.thingiverse.com] and [www.thingiverse.com]
Please note my approach uses a new Arduino Pro Mini per axis for the closed-loop logic (encoder and step counts and motor location PID loop).
