grbl is stepper motor controller ... that are too powerful for the normal drivers included on grbl Arduino shields (or integrated Arduino+drivers equivalents), and so I have been considering designing ...

Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver ... Arduino library will help you out. Who else is usi ...

How does a stepper motor turn into an encoder? Well, that’s the MacGyver part. We are not big fans of the physical circuit ... an Arduino reads the pulses. We love using things for unintended ...
