Submitting Patches

Proposed patches should be submitted as a Pull Request against this branch (bugfix-1.1.x).

  • This branch is for fixing bugs and integrating any new features for the duration of the Marlin 1.1.x life-cycle. We've opted for a simplified branch structure while we work on the maintainability and encapsulation of code modules. Version 1.2 and beyond should improve on separation of bug fixes and cutting-edge development.
  • Follow the proper coding style to gain points with the maintainers. See our Coding Standards page for more information.
  • Please submit your questions and concerns to the Issue Queue. The "naive" question is often the one we forget to ask.

License

Marlin is published under the GPL 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.

While we can't prevent the use of this code in products (3D printers, CNC, etc.) that are closed source or crippled by a patent, we would prefer that you choose another firmware or, better yet, make your own.
