What is GRBL?
GRBL is a free, open-source firmware used to control the motion of machines. It's limited to Arduino-based controllers.
How do I find out if my machine has GRBL?
By default, all Inventables machines are running on GRBL. If you do not have an Inventables CNC, the first step is to identify which motion controller you have. If it's Arduino-based, chances are it's running on GRBL. You may need to reach out to your machine provider and ask for the firmware version.
How do I install GRBL onto my machine?
You can follow these instructions.
Where can I find the source code?
The Inventables fork of the project is here.
Our fork is used for our production configuration management. We currently only make changes to configurable settings to tailor it to an X-Carve or X-Carve Pro.

My machine doesn't run on GRBL. Can I still use Easel?
The Easel driver will only work with GRBL controllers. While you won't be able to connect your machine directly to Easel, you could still set up your project and export it as a gcode file. You would then need to use another gcode sender to run the carve.
