[Jim Fong] sent in this demo of his version of the UHU servo motor controller. [Uli Huber] has actually shipped over 2500 controllers for the servo. He doesn’t charge much for the chips, and only asks ...

It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

It is an engineering truism that there is no such thing as a perfect solution—just the best solution for the problem at hand. That holds particularly true for servo motors and stepper motors. Both are ...
