If you are interested in building your very own full instructions on how to combine the Arduino CNC shield and Arduino code for controlling the to DC servo motors have been kindly published to the ...

This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a special mechanical switch to select the operating mode.

This shield could be a good alternative to hobby RC controllers for robots that need a customizable open-source motor controller. The PCB design and source code are available on GitHub.
