The motors are off the shelf stepper motors dr​iven by a 30 kHz closed loop controller and a very precise PWM signal. A 'magnetic gearing' approach increases the resolution of the low-cost magnetic rotary encoders by a factor of 30 allowing for steps down to 50nm -(**Please mind the difference between resolution and accuracy**. The absolute accuracy is much lower). +(**Please mind the difference between resolution and accuracy**. The absolute accuracy is significantly worse. The device can be controlled via simple G-Code commands over a USB serial interface and is thus easily integrated into other projects. The firmware implements a complete motion planning stack with look-ahead for smooth and accurate path following capabilities.
