Stepoko: Powered by grbl Hookup Guide
The SparkFun Stepoko is an ATmega328p, Arduino compatible, 3-axis control solution. It’s open source, uses open source firmware and works with an open source Java based cross platform G-Code sending application.
The SparkFun Stepoko, in all its glory.
The simplest installation of it consists of just plugging the stepper motors in, but of course hard work pays off. Handy machine control buttons and locating features can be added at taste to give a mill whichever options are desired.
