Very nice project. As described in the video, for servo motor v dumb stepper, servo motor is more efficient and servo motor won’t miss steps, or at least not without being able to provide a warning.

You get the efficiency of a servo motor at the cost of a stepper motor.” It is designed for coil currents up to 0.7Arms (1A peak) and a nominal 24Vdc supply that can vary across 9 to 28V. Three ...
