The solution is named Ethersweep, and is a small PCB stack that sits on the rear of the common NEMA17-format stepper motor ... with Arduino covering the firmware and host control side in python.

control the motor rotation and listen on the ‘stepper motor driver’ interface pins hooked up to the motion controller upstream. The Arduino source for this can be found on the project GitHub.

ClearCore CLCR-4-13 is an industrial IO and motion controller that can be programmed using the Arduino IDE. It handles up to four axes of step-and-direction motion control (500kHz max step rate), and ...
