Marlin-2.0.x_config

Marlin 2.0.x custom configuration files for my upgraded Ender 3 Pro. These files are specific to my setup and are provided for educational purposes only. Use at you own risk!

Configuration

Ender 3 Pro or Ender 3 V2 or Ender 5 Pro
Creality V4.2.2 or V4.2.7 mainboards or BigTreeTech SKR Mini E3 3.0
Marlin 2.0.9.3 firmware
E3D V6 hotend
BondTech BMG extruder
BLTouch Auto Bed Leveling sensor (Connected to the dedicated 5 pins connector of the Creality V4.2.7 board, not to the Z min stop pins)

How to compile & build?

Download the Marlin source code (https://marlinfw.org/meta/download/ or https://github.com/MarlinFirmware/Marlin)
Overwrite the default configuration files in the Marlin directory (Configuration.h, Configuration_adv.h etc.) with the files provided
Install Microsoft Visual Studio Code + PlatFormIO IDE (see https://marlinfw.org/docs/basics/install_platformio_vscode.html)
Install the "Auto Build Marlin" extension (see https://marlinfw.org/docs/basics/auto_build_marlin.html)
Compile & Build Marlin with a single click using the Auto Build Marlin extension (see see https://marlinfw.org/docs/basics/auto_build_marlin.html)

How to install?

Copy the firmware binary (e.g. .pio/build/STM32F103RET6_creality/firmware-20210906-101846.bin) to the root directory of an SD card. Make sure you use always a new filename! (Note: For the BigTreeTech SKR Mini E3 mainboard, always rename the firmware binary to "firmware.bin")
Insert the SD card into your printer and power it on. This should update the firmware with the binary provided

How to check the firmware version?

On the printer, click on About Printer > Printer Info

What to do next?

Initialize EEPROM (Configuration > Advanced Settings > Initialize EEPROM)
Restore all settings to their default values (Configuration > Restore Defaults)
Update the Z offset (Configuration > Probe Z Offset). This is the distance between nozzle and the probe tripping point. The expected value should be between -2.0 mm and -4.0 mm.
[Optional] Enable firmware retractions (Configuration > Retract > Auto-Retract) and adjust retraction settings as needed
Save the current configuration in EEPROM (Configuration > Store Settings)
Enjoy some good old retro games! (About Printer > Games)
