Grbl is high performance, low cost, based on parallel motion control, for CNC engraving. It can run in Vanilla Arduino (Duemillanove/Uno) as long as it is equipped with a Atmega 328 chip. The controller is written and optimized by C and uses every smart feature of the AVR chip to achieve precise timing and asynchronous control. It can maintain a stable, unbiased control pulse over 30kHz, which accepts standard G code and passes the output test of several CAM tools. The motion of arc, round and spiral can be as perfect as other basic G code commands. Functions and variables are not currently supported, but they are included as preprocessors in future releases. Grbl contains complete forward-looking acceleration control. It means that the controller will advance 16 to 20 movements to plan the running speed to achieve smooth acceleration and no impact turn.
