Update V400 Motherboard Firmware (MKS Nano V3.0 & V3.1) - Guilouz/Klipper-Flsun-Speeder-Pad GitHub Wiki

It's important that your motherboard firmware version matches with the installed Klipper version.

Version is visible on System Loads tile -> mcu section (in Machine tab).

  • In the SSH command prompt window, enter the following commands (one at a time): 
    cd ~/klipper/

    make menuconfig
  • Move on the menu with the Up and Down keys of your keyboard and validate the selected item with the Enter key and select these settings:

  • Then on your keyboard press the Q key then Y to save configuration.

  • Enter the following commands to compile firmware (one at a time):

    make clean

    make

  • V400 motherboard doesn't support DFU mode, so it's not possible to install the firmware directly. It's therefore necessary to install it manually.

  • Get the firmware named klipper.bin in /home/pi/klipper/out/ directory (on the left part of MobaXterm).

  • Rename it to Robin_nano_v3.bin and copy it to the root of an microSD card formatted in FAT32 and an allocation size of 4096. Use a small size like 128MB or 256MB for microSD because some motherboards do not support microSD with large capacity for flash.

  • Insert the microSD card into the motherboard then turn on the printer.

  • Installation only takes a few seconds, to verify that the firmware has been successfully installed, the file on the microSD card must have been renamed to ROBIN_NANO_V3.BIN.CUR.
