    • Create the CAN0 interface file

    • sudo nano /etc/network/interfaces.d/can0

    • Enter the following

    • auto can0 iface can0 can static bitrate 500000 up ifconfig $IFACE txqueuelen 256 pre-up ip link set can0 type can bitrate 500000 pre-up ip link set can0 txqueuelen 256

    • You can copy paste into the file but make sure your formatting is correct to include the single space in the beginning of the last 4 lines.

    • Exit and save the file with CTRL + SHIFT X > Yes

    • Sudo Reboot

    • The CAN board needs a bootloader so we can flash the Klipper firmware. We will use CanBoot. Download the CanBoot repository:

    • git clone https://github.com/Arksine/CanBoot

    • cd CanBoot

    • make clean

    • make menuconfig

    • Add the 5v jumper. Connect the USB-C from the Pi to the EBB36 board.

    • Put the EBB36 into DFU mode

    • Press and hold the RESET + BOOT button. Release the RESET button while holding the BOOT button, than release the BOOT button.

    • Get the device ID of the board after it's in DFU mode

    • Before DFU mode

    • In DFU mode

    • Erase and flash the firmware

    • sudo dfu-util -a 0 -D ~/CanBoot/out/canboot.bin --dfuse-address 0x08000000:force:mass-erase:leave -d DEVICE:ID

    • Power off the system. Plug in the 4 wire CAN cable from the UT0C to the EBB36, and power on the the printer and RPI.

    • After the system is powered up verify the CAN network is up.

    • cd klipper

    • python3 lib/canboot/flash_can.py -q

    • You should see 1 entry for application CanBoot. Note your UUID.

    • Run

    • cd ~/klipper

    • make menuconfig

    • Select the following

    • Enable extra low-level configuration

    • Micro-controller Architecture > (STMicroelectronics STM32)

    • Processer model > STM32F072

    • Bootloader offset > (8KiB bootloader)

    • continued:

    • Clock Reference > (8 MHz)

    • (500000) CAN bus speed

    • Save the configuration pressing ESC > Yes

    • Run

    • make clean

    • make

    • flash the EBB36 with the newly compiled firmware

    • python3 ~/CanBoot/scripts/flash_can.py -i can0 -f ~/klipper/out/klipper.bin -u 9fd4db4bdbc0

    • sudo dfu-util -a 0 -d 0483:df11 --dfuse-address 0x08000000 -D ~/CanBoot/out/canboot.bin

    • If all goes well your CAN board should now be flashed

    • run

    • ~/klippy-env/bin/python ~/klipper/scripts/canbus_query.py can0

    • Load the provided files to the printer and press FIRMWARE_RESTART

    • Checking the Machine tab you should see the 4 systems
