This is an inofficial derivative of the Meachaduino Project: https://hackaday.io/project/11224-mechaduino
The original Mechaduino is a cool project, but is designed for stepper drivers with properties of a typical NEMA 17. When you want to drive a CNC-Mill, you require stepper motors the size of a NEMA 23 (or bigger). This project tries to make a "HighPower" Version of the Mechaduino including some improvements, based on the original design from Tropical Labs.
Please note that the project is still in development, and not ready for production use!
