About
grbl is an open-source, embedded, high-performance g-code parser and CNC milling controller. Written in optimized C, it is designed to run on a vanilla Arduino (Duemillanove/Uno) with an Atmega 328, offering a low-cost alternative to parallel-port-based motion control for CNC milling. The controller utilizes clever features of AVR-chips to achieve precise timing and asynchronous operation, maintaining up to 30kHz of stable, jitter-free control pulses. It accepts standards-compliant g-code, supporting arcs, circles, helical motion, and primary g-code commands. Grbl includes full acceleration management with look-ahead, planning velocities up to 18 motions into the future for smooth acceleration and jerk-free cornering. It is released under the GPLv3 license.
