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 ... to 4 seconds (≙ 5). I want torque, so I ...

[Ken]’s Easy Stepper Motor Controller is a much simpler solution to the problem of testing these drivers and could, with a bit of practice, be constructed on a single-sided homebrew PCB.

The type of driver has a large influence on the stepper motor system's overall performance, specifically its torque, output power, and speed. Distinguishing between the different types is important ...
