It will run on a vanilla Arduino (Duemillanove\u002FUno) as long as it sports an Atmega 328. \n\nThe controller is written in highly optimized C utilizing every clever feature of the AVR-chips to achieve precise timing and asynchronous operation. It is able to maintain up to 30kHz of stable, jitter free control pulses.\n\nIt accepts standards-compliant g-code and has been tested with the output of several CAM tools with no problems. Arcs, circles and helical motion are fully supported, as well as, all other primary g-code commands. Macro functions, variables, and most canned cycles are not supported, but we think GUIs can do a much better job at translating them into straight g-code anyhow.\n\nGrbl includes full acceleration management with look ahead. That means the controller will look up to 18 motions into the future and plan its velocities ahead to deliver smooth acceleration and jerk-free cornering.\n\n* [Licensing](https:\u002F\u002Fgithub.com\u002Fgrbl\u002Fgrbl\u002Fwiki\u002FLicensing): Grbl is free software, released under the GPLv3 license.\n\n* For more information and help, check out our **[Wiki pages!](https:\u002F\u002Fgithub.com\u002Fgrbl\u002Fgrbl\u002Fwiki)** If you find that the information is out-dated, please to help us keep it updated by editing it or notifying our community!
