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 ...

Although many schematic diagrams show pronounced ... The trade-off between uni- and bipolar stepper motors is thus basically one between driver and stepper motor complexity. Yet as bipolar stepper ...

How does a stepper motor turn into an encoder? Well, that’s the MacGyver part. We are not big fans of the physical circuit diagrams ... Of course, an Arduino reads the pulses.
