Ender 3 Pro upgrade issues

  • Hello, I am in the process of upgrading a few components of my Ender 3 pro printer and have a few issues I am seeing.

    I have purchased a Mute Main Board (4.2.7) along with a BL Touch level system.

    I have everything apart have done the board swap now when installing the BL Touch I have noticed there is no location to update the firmware on this new board.... where do I plug this in and how do I continue??

  • Hi, you might flash the firmware in the wrong way, if it is a 32-bit motherboard, pls format your SD card first, and copy the firmware in your SD card, insert it into the Card slot, turn on the machine, it will automatically be flashed, you can check this video for reference: https://www.youtube.com/watch?v=ZPqpZwl-NTw
