Controlling the motors is done through [Guy Carpenter]’s Switec X25 library for the Arduino, allowing an Arduino Uno to control up to three stepper motor gauges simultaneously.

Leveraging the Trinamic TMC2208 stepper motor driver gives Ethersweep silky smooth and quiet motor control, which could be very important for some applications.

Makers, developers and Arduino enthusiasts searching for silent stepper drivers with high resolution encoders which are also Arduino compatible.
