Marlin Firmware

Open-source 3D printer firmware for 8-bit and 32-bit boards, used by many commercial printers.

PlatformWebfree

Marlin is open-source firmware for RepRap-style 3D printers that runs on both 8-bit AVR and 32-bit ARM control boards and ships on many commercial machines. A hardware abstraction layer lets one code base cover more than a dozen board platforms, with support for multiple axes and extruders. It is built with PlatformIO or the Arduino IDE from per-machine configuration files, serving printer builders, modders and upgraders.
