This is my Fork of grbl. It is based on the eddge branche and uses L6474 Stepper-drivers from ST. I am using 4 X-NUCLEO-IHM01A1 boards and a custem board with a Atmega1284p controller.

Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. * Licensing: Grbl is free software, released under the GPLv3 license.
