Introduction
Stepper motors are the simplest drive for moderate precision motion control applications (such as CNC plasma cutting). They provide the best price:performace for low to moderate mechanical power (<200W) at low to moderate RPM (<500 RPM). There is no open source stepper driver, AFAIK. This project will fill that need.
Concept
The output of this project will be a family of general purpose electronic drivers for a variety of electromechanical actuators. The first of them will be a stepper motor driver. With the appropriate alternative firmware (embedded software) the same hardware might be used as a servo driver for a brush-DC servo. With a modified output stage we could drive brushless DC or AC servos, or linear motors.
