Optimized firmware for RepRap 3D printers based on the Arduino platform
README.md

Marlin Firmware logo

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

The complete project includes these components:

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