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.

A lot of making goes on in this community these days, but sometimes you’ve just gotta do some old fashioned hacking. You might have grabbed an old Speak and Spell that you want to repurpose ...

Abstract: This article presents a multidelayed repetitive control (MDRC) scheme to achieve the ultra-precision tracking control of the fast tool servo (FTS) for diamond turning of functional surfaces.

Abstract: Super-twisting sliding mode (STM) control offers advantages, such as fast response and low demand on motor model accuracy, and is attractive for the permanent magnet synchronous motor (PMSM) ...
