Target printer: Printrbot simple metal (150mm cube) with heated bed
Many thanks to JDWallace for providing instruction: https://www.jdwallace.com/post/printrbot-simple-metal-marlin2
and config: https://github.com/jdwallace/3d-printing
Changes/Differences:
- Set the print volume to 150mm cube
- Included the full Marlin code base (Branched from Marlin 2.0.X-bugfix)
- Updated the configuration files to fix errors in the build
Marlin readme follows:
Additional documentation can be found at the Marlin Home Page. Please test this firmware and let us know if it misbehaves in any way. Volunteers are standing by!
Not for production use. Use with caution!
Marlin 2.0 takes this popular RepRap firmware to the next level by adding support for much faster 32-bit and ARM-based boards while improving support for 8-bit AVR boards. Read about Marlin's decision to use a "Hardware Abstraction Layer" below.
This branch is for patches to the latest 2.0.x release version. Periodically this branch will form the basis for the next minor 2.0.x release.
Download earlier versions of Marlin on the Releases page.
Before building Marlin you'll need to configure it for your specific hardware. Your vendor should have already provided source code with configurations for the installed firmware, but if you ever decide to upgrade you'll need updated configuration files. Marlin users have contributed dozens of tested example configurations to get you started. Visit the MarlinFirmware/Configurations repository to find the right configuration for your hardware.
To build Marlin 2.0 you'll need Arduino IDE 1.8.8 or newer or PlatformIO. We've posted detailed instructions on Building Marlin with Arduino and Building Marlin with PlatformIO for ReArm (which applies well to other 32-bit boards).
Marlin 2.0 introduces a layer of abstraction so that all the existing high-level code can be built for 32-bit platforms while still retaining full 8-bit AVR compatibility. Retaining AVR compatibility and a single code-base is important to us, because we want to make sure that features and patches get as much testing and attention as possible, and that all platforms always benefit from the latest improvements.

Proposed patches should be submitted as a Pull Request against the (bugfix-2.0.x) branch.
- This branch is for fixing bugs and integrating any new features for the duration of the Marlin 2.0.x life-cycle.
- Follow the Coding Standards to gain points with the maintainers.
- Please submit Feature Requests and Bug Reports to the Issue Queue. Support resources are also listed there.
- Whenever you add new features, be sure to add tests to
buildroot/testsand then run your tests locally, if possible.- It's optional: Running all the tests on Windows might take a long time, and they will run anyway on GitHub.
- If you're running the tests on Linux (or on WSL with the code on a Linux volume) the speed is much faster.
- You can use
make tests-all-localormake tests-single-local TEST_TARGET=.... - If you prefer Docker you can use
make tests-all-local-dockerormake tests-all-local-docker TEST_TARGET=....
The Issue Queue is reserved for Bug Reports and Feature Requests. To get help with configuration and troubleshooting, please use the following resources:
- Marlin Documentation - Official Marlin documentation
- Marlin Discord - Discuss issues with Marlin users and developers
- Facebook Group "Marlin Firmware"
- RepRap.org Marlin Forum

Marlin is constantly improving thanks to a huge number of contributors from all over the world bringing their specialties and talents. Huge thanks are due to all the contributors who regularly patch up bugs, help direct traffic, and basically keep Marlin from falling apart. Marlin's continued existence would not be possible without them.
Regular users can open and close their own issues, but only the administrators can do project-related things like add labels, merge changes, set milestones, and kick trolls. The current Marlin admin team consists of:

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.
