This repository contains Marlin custom config files for Creality Ender-5 printers with a BIGTREETECH SKR Mini E3 v1.0 motherboard. Settings used are also compatible with Ender-3 and Ender-3 Pro, just be sure to use the correct config examples for your printer. For more information about which settings to change please browse to the config folder in this repository and read the readme.md files.
Please note that this configuration is not compatible with SKR Mini E3 v1.2 or v2.0.
Features:
- Stock Ender-5/Ender-3/Ender-3 Pro LCD 12864 support.
- BL Touch 3.x support (connected to dedicated on board port).
- EEPROM support.
- Works with Octoprint.
- Compatible with Marlin 2.0.6.
Please read section Configuration changes for late 2019 Ender-5 printers if you have an Ender-5 printer shipped from mid/end 2019.

- Get the latest Marlin bugfix-2.0.x from the official site here: http://marlinfw.org/meta/download/.
- Copy files from folder \Config_BLTouch31\Config_Files in this repository to the folder \Marlin in your firmware root folder.
- Optional: Copy files from folder \Config_BLTouch31\Board_Pins in this repository to the folder \Marlin\src\pins\stm32f1 in your firmware root folder if you want to use BL Touch dedicated port (PC14) instead of the default Z end stop pin (PC2).
- Copy files from folder \Config_BLTouch31\Compiler_Settings in this repository to the your firmware root folder.
- Compile the software and flash the board.
- Optional: Do a "Restore failsafe" from the printer's menu or delete file EEPROM.DAT from the SD Card before powering on to make sure that the printer is running with the default values and avoid malfunction.
In late 2019, Creality changed the Z leadscrew on Ender-5 matching the one shipped with the Ender-5 Pro to prevent the bed from dropping after power cuts. If your printer shipped with the new leadscrew you'll need to change DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 93 } to DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 800, 93 } in Configuration.h.
If you are unsure which leadscrew you printer has but your prints are half as tall as they should be, then your printer should have the new version of the leadscrew and you need to change Z stepping configuration.

Below is a picture showing where to connect your BL Touch if you wish to use the dedicated on-board port. This not required but it leaves Z end stop port available if you want to repurpose it. In this case you need to follow step 3 from the Installation guide for Printers with BL Touch 3.1.
Below is a picture showing where to connect your BL Touch if you wish to use the Z end stop pin. In this case you have to skip step 3 from the Installation guide for Printers with BL Touch 3.1.
Below are two pictures that show how to connect BL Touch to a stable, low noise power source in order to fix the probing issues caused by SKR Mini E3 5v rail problem.
To do:
- Create and test a common ground between buck converter and SKR Mini E3 board.
Buck converter specs:
- Type/name: LM2596HVS DC-DC step-down module
- Input Voltage: 4.5V ~ 53V
- Output Voltage: 3V ~ 40V
- Output Current: 3A (max)
- Conversion efficiency: 92%(the highest)
- Output Ripple: <30mV
- Switching frequency: 150KHz
- Operating Temperature: -45 ° ~ +85 °
- Size: 43mm * 21mm * 14mm (L * W* H)
