The project illustrates the use of a PIC microcontroller in creating the stepper motor controller by sequencing the steps, along the with TIP120 Darlington pairs for the switching circuitry, and a ...

Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver IC. Although they power most of our CNC machines and 3D printers, ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...
