Creality Ender 6 Firmware | V4.3.X Board
Do you have an Ender 6 and want a stable firmware with the latest features?
Board Limitations Note: Due to the design of the Creality boards with TMC drivers Linear Advance will probably not work correctly. The feature is available but use at your own risk.
Maybe you’re adding our EZABL kit to the machine. This is the download for you. Directions are below.
LCD Note: This does NOT work with the stock LCD due to its closed source firmware. This firmware ONLY works when you have the 12864 LCD upgrade kit installed. You can get that kit here: TH3D Ender 6 LCD Conversion Kit
Supported CPU List
- STM32F103 RCT6/RET6

We also recommend you download the Unified 2 STL pack as well. This contains EZABL mounts, Gantry leveling Blocks, Solid bed mounts, and Bed Level test files. Click here to go to the Unified 2 STL Pack download page.
1 – Printer Board Firmware Update
NOTE: Every time you flash the firmware it must start with firmware followed by random numbers/letters. It must be a different file name every time you flash. This is a limitation with the bootloader on these boards. It will NOT rename the file like other boards after it flashes.
1.b –Download the firmware
1.c –Extract the files to a folder on your computer
1.d –Open the folder labeled “Firmware” in VSCode
1.e –Open the Configuration.h file that is located under the “Marlin” folder on the left side of the VSCode screen
1.f – In the Configuration.h file, uncomment (remove the 2 / in front of #define) the ENDER6_V431_BOARD line and any other options you are going to use in the firmware. Uncomment the option for the board version you have.
1.g – Click the ✓ at the bottom of VSCode to compile the firmware. The firmware will compile. This may take 1-5 minutes depending on the speed of your computer and internet connection
1.h –On the left side of VSCode expand “.pio” and “build” until you see the STM32F103RCT6_creality/STM32F103RET6_creality folder. Right click on the STM32F103RCT6_creality/STM32F103RET6_creality folder and click “Reveal in File Explorer”
1.i –In the file explorer open the STM32F103RCT6_creality/STM32F103RET6_creality folder
1.j –Look for the latest firmware-XXXXXXXX-XXXXX.bin file and copy that to your SD card. This SD card must be FAT32 formatted. If you compiled more than one time you will see multiple firmware files. Use the latest one based on the date the file has.
1.k –Power OFF your printer and Insert the SD card with the latest firmware-XXXXXXXX-XXXXX.bin file into your printer. Turn the printer on. It will take a little longer than normal to boot up.
1.l –When the printer boots you will see the TH3D logo on your LCD. Make sure to reset your EEPROM on your printer after flashing any firmware. You can do this from your printer LCD or by sending a M502 followed by M500 with your favorite Gcode sender application.
