The Arduino source for this can be found on the project GitHub. Whilst [Frank] mentions that this assembly has a weight and torque advantage over a NEMA 17 sized stepper motor, but we see no hard ...

The Arduino drives the stepper motor through an Adafruit Motor Shield, with a simple user interface running on the LCD. The user can set the desired end points and speed, and then run the camera ...

grbl is stepper motor controller ... for the normal drivers included on grbl Arduino shields (or integrated Arduino+drivers equivalents), and so I have been considering designing my own to link to ...
