Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. This version of Grbl runs on an Arduino with a 328p processor (Uno, Duemilanove, ...

His offering uses the Arduino Uno, but there are several other hardware options covered as well. The firmware makes use of the serprog-duino library which was crafted at writing to flash memory chips.

GRBL is a firmware for arduino boards (uno,nano,Duemillanove) that controls stepper motors and spindles/lasers. GRBL uses gcode as input and outputs signals via the arduino pins. Most industrial cnc ...

The G-code file generated is given as input to the GRBL-Arduino based controller using the Java-based Windows application Universal GcodeSender (UGS). UGS is linked to the Arduino Uno and GRBL shield ...
