Marlin 3D Printer Firmware

Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. First created in 2011 for RepRap and Ultimaker printers, today Marlin drives a majority of the world's most popular 3D printers. Marlin delivers outstanding print quality with unprecedented control over the process.

Marlin 1.1.x

This 1.1.x Release Branch contains the latest tagged version of Marlin (currently 1.1.8 – December 2017).

Marlin 1.1 represents an evolutionary leap over Marlin 1.0. It is the result of over two years of effort by several volunteers around the world who have paid meticulous and sometimes obsessive attention to every detail. We've focused on code quality, performance, stability, and overall user experience. Several new features have been added, many of which require no extra hardware.

Marlin 1.0.x

Previous releases of Marlin include 1.0.2-2 (December 2016) and 1.0.1 (December 2014). Any version of Marlin prior to 1.0.1 (when we started tagging versions) can be collectively referred to as Marlin 1.0.0.

License

Marlin is published under the GPLv3 license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.
