# Creality Ender Support
This branch is a reverse-engineered version based on the unpublished firmware from Creality. It is **not** the authoritative source, but has been carefully re-built by looking at their firmware and inferring the base version and configuration they used. The basis is the firmware version from "Jul 31 2017 10:16:30". It is based on 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`.
Configurations were found by seeing what code was compiled into the firmware, and constants used there.
For U8Glib, at least version 1.14 and at most 1.17 is 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.
## Bitmaps
The bootscreen and custom status screens come from Creality's firmware.
## Creality Ender-2 firmware status
The firmware source code has been published on 2018/07/10.
It is based on Marlin 1.1. The source code and .hex binaries for all printers (including Ender-2) can be obtained from:
https://www.creality3d.cn/download/firmware_c0001
And repositories for CR-10S and Ender-3 can be found here:
https://github.com/Creality3DPrinting
The configuration files have been verified to match the original configuration, but further investigation is needed to ensure there aren't any extra changes in the source code.
## Ender-2 specific changelog:
* 2018/10/08 - Updated BED_MAXTEMP to 75 to match the original Creality Ender-2 Firmware (which is now open source)
