Marlin Firmware is an open source firmware for 3D printers, Plotters, Foam-cutters, Laser-cutters, and CNC routers.

The complete project includes these components:

Marlin : The firmware source code. Authorized for use under the GPLv3 License.
Configurations : Example configurations for a wide variety of machines.
MarlinDocumentation: Jekyll source code for the marlinfw.org website.
AutoBuildMarlin: A Visual Studio Code extension used to configure, build and install Marlin Firmware.

We also maintain a few supporting libraries required for a proper build of Marlin Firmware.
