Creality Ender 3/3 Pro & Ender 5/5 Pro Firmware | V4.2.X Board

  • Posted

Do you have an Ender 3/3 Pro or Ender 5/5 Pro with the V4.2.2 or V4.2.7 board and want a stable firmware with the latest features? Looking to get a V4.2.7 board? Get it here from TH3D.

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.

This firmware is ONLY for the Ender 3/3 Pro or Ender 5/5 Pro with the new V4.2.X board from Creality. If you have the older V1.1.X board you will need to use the firmware for the Melzi Board.

Download

Places-folder-downloads-icon__1_.png Unified 2 Firmware for the Ender 3/3 Pro & Ender 5/5 Pro with V4.2.X Board

Supports our EZABL Pro Auto Bed Leveling Kit - sensor mount STL file included in download.

Installation Directions

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. Setup VSCode with our installation guide
  2. Download the firmware
  3. Extract the files to a folder on your computer
  4. Open the folder labeled "Firmware" in VSCode
  5. Open the Configuration.h file that is located under the "Marlin" folder on the left side of the VSCode screen

  6. Ender 3: In the Configuration.h file, uncomment (remove the 2 / in front of #define) the ENDER3_V422_BOARD or ENDER3_V427_BOARD line and any other options you are going to use in the firmware 
    Ender 5:     In the Configuration.h file, uncomment (remove the 2 / in front of #define) the ENDER5_V422_BOARD or ENDER5_V427_BOARD line and any other options you are going to use in the firmware 

    Uncomment the option for the board version you have.
  7. 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

  8. On the left side of VSCode expand ".pio" and "build" until you see the STM32F103RET6_creality folder. Right click on the STM32F103RET6_creality folder and click "Reveal in File Explorer"

  9. In the file explorer open the STM32F103RET6_creality folder

  10. 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.

  11. 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.
  12. 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.

    Swapped out my 1.1.4 board from my Ender 3 Pro (With EZABL) today and followed the steps in this guide. All up and running - Thank you.

    Tips:
    1. You do need to enable one of the mount options.
    2. There are some temperature and esteps that needed dialing back and a couple items disabled.. Make sure you look at all values..

    Again, this guide and firmware allowed me to get my 4.2.7 board working as I needed it with the EZABL.

    Hi,

     

    Ender 5 with Motherboard 1.1.5 swapped to Creality 4.2.7 board.

    Flashed TH3D firmware.

    It keeps beeping while bed is heating.

    Once at temperature, it does sometimes beep.

    Can't figure out what's wrong.

     

    If I put back old motherboard, everything is OK so I would say my bed sensor is OK.

    Any help appreciated.
