Configuring and installing Klipper for USB to CAN Bridge Mode

Compile Klipper firmware for Fly-E3-v2

  • ssh to your klipper host console

  • cd to the klipper directory

    cd ~/klipper

  • Run make clean

    make clean KCONFIG_CONFIG=config.e3v2

  • Open menuconfig

    make menuconfig KCONFIG_CONFIG=config.e3v2
  • Set the following settings
    • [*] Enable extra low-level configuration options
    • Micro-controller Architecture (STMicroelectronics STM32)
    • Processor model (STM32F407)
    • Bootloader offset (32KiB bootloader)
    • Clock Reference (8 MHz crystal)
    • Communication interface (USB to CAN bus bridge (USB on PA11/PA12))
    • CAN bus interface (CAN bus (on PB8/PB9))
    • USB ids
    • (1000000) CAN bus speed

    • () GPIO pins to set at micro-controller startup

  • Quit and save the configuration

  • Run Make to compile the firmware

    make KCONFIG_CONFIG=config.e3v2 -j4

Flash Klipper USB firmware with Katapult over USB

  • Find the Serial ID

    ls /dev/serial/by-id/

  • Copy the ID containing ‘STM32’ and make a note of it for use in your printer.cfg.

  • Run the make flash command to flash the firmware

    make KCONFIG_CONFIG=config.e3v2 flash FLASH_DEVICE= {Your serial ID here }

  • Example

    make KCONFIG_CONFIG=config.e3v2 flash FLASH_DEVICE=/dev/serial/by-id/usb-katapult_stm32f407xb_170038000650314D35323820-if00
    Burn Klipper firmware over USB
