Tommie Gannert f3f26f7cb3 Creality Ender support. 
Reverse engineered from the unpublished firmware from Creality,
inferring the base version and configuration they used. The basis is
the firmware version from "Jul 31 2017 10:16:30". Configurations were
found by seeing what code was compiled into the firmware, and
constants used there.

They used Marlin 1.0.1, because

* 1.0.0 had very different serial output in `setup()` and overall
  code structure.
* 1.0.2 changed the `VERSION_STRING` to include a leading space,
  and `lcd_init` uses `SET_INPUT` instead of `pinMode`.

For U8Glib, a version between 1.14 and 1.17 was used, because

* 1.12 didn't have the extra speed argument to u8g_InitCom.
* 1.13 didn't have the soft reset instruction for UC1701 initialization.
* 1.18 has a new directory structure.

Quirks

* The value of PID_dT hints that F_CPU is 20M, but MarlinSerial.begin
  suggests it's indeed 16M (and the board uses 16M). Left at 16M for now.

* The LED and DOGLCD_CS are on the same pin.

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!

Bugfix Branch

Not for production use. Use with caution!

This branch is used to accumulate patches to the latest 1.1.x release version. Periodically this branch will form the basis for the next minor 1.1.x release.

Download earlier versions of Marlin on the Releases page. (The latest tagged release of Marlin is version 1.1.7.)

Recent Changes

  • Internally always use native machine space
  • Initial UBL LCD Menu
  • New optimized G-code parser singleton
  • Initial M3/M4/M5 Spindle and Laser support
  • Added M421 Q to offset a mesh point
  • Refinements to G26 and G33
  • Added M80 S to query the power state
  • "Cancel Print" now shuts off heaters
  • Added EXTRAPOLATE_BEYOND_GRID option for mesh-based leveling

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 2.0 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.
