This page is dedicated to the EBB36/42.

The EBB36/42 Version 1.1 have a fatal flaw in DFU Mode. Please UNPLUG the hotend HEATER or 24V when in DFU.

Generate the Katapult(formerly CanBoot) firmware file

  1. clone the Katapult repository to your pi

    cd ~/
git clone https://github.com/Arksine/katapult

  2. run the following

    cd katapult
make menuconfig

  3. Configure your makefile for the EBB 36 / 42 v1.1/v1.2 with STM32G0B1 choose the corresponding Version of your board below

    Firmware Configuration for the EBB36/42 V1.0

    ../images/ebb36-42_v1.0_make.png Exit using ESC or Q, confirm with yes(Y)

    Firmware Configuration for the EBB36/42 V1.1/2

    ../images/ebb36-42_v1.1_make.png Exit using ESC or Q, confirm with yes(Y)

  4. Build the firmware

    make clean

make

Hook up the Board for flashing

The EBB36/42 Version 1.1 have a fatal flaw in DFU Mode. Please UNPLUG the hotend HEATER or 24V when in DFU.

  1. Add the 5v jumper to the pins highlighted below

  2. Connect your device to your PI via USB

  3. Hold the RESET button and BOOT shown above
    • Release Reset
    • Release Boot
  4. Verify the device is in bootloader moad by using lsusb
    • you should see something like 
         Bus 001 Device 005: ID 0483:df11 STMicroelectronics STM Device in DFU Mode

  5. Flash the katapult bootloader to the board YOUR DeviceID (0483:df11) may be different CHECK IT! (see step 4)

  6. ERASE AND FLASH THE Katapult FIRMWARE

    sudo dfu-util -a 0 -D ~/katapult/out/katapult.bin --dfuse-address 0x08000000:force:mass-erase:leave -d 0483:df11

NOTE: If you see an error after the above, don’t worry its fine, provided you have the “File Downloaded Sucessfully” and text above

  1. Power off the Board, and insert the CANBUS cable

Klipper flashing

If you havent setup your network yet, NOW is your last chance before it becomes a problem, click here, and select your control board for instrutions, then return here and carry on :)

  1. You can now power up your printer with the toolhead board attached via the appropriate wiring scheme using the H L 24v and gnd wires.

  2. Wait for the device to boot and ensure your CAN0 network is up and you can see the device

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

    or

    ~/katapult/scripts/flash_can.py -i can0 -q

    You should see something like

    "Found canbus_uuid=XXXXXXXXXX, Application: katapult"

  3. Assuming the above gave you a UUID you can now flash Klipper to your board via Katapult…

    cd ~/klipper
make menuconfig
    Firmware Configuration for the EBB36/42 V1.0

    ../images/sht_klipper_canboot.png

    Firmware Configuration for the EBB36/42 V1.1/2

    ../images/g0b1_klipper_make.png

    Hit Q to exit and select Y to save changes.

    make clean
make

    You can now flash the board

    python3 ~/katapult/scripts/flash_can.py -i can0 -f ~/klipper/out/klipper.bin -u MYUUID

    If all is well you now have a klipper firmware on your EBB36/42.

    To verify this you can query the canbus uuid with

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

    You should see something like

    "Found canbus_uuid=XXXXXXXXXX, Application: Klipper"
