SPIDER V2.2 MCU FW INSTALL/UPDATE

The firmware installation process for the Fysetc Spider MCU

Prerequisites:

  • Klipper must be installed onto the Raspberry Pi
  • Take two blue jumpers out of the Fysetc Spider box
  • You should have physical access to the MCU
  • Voron Design recommends using USB to control the Spider, which simply requires connecting a USB-A to USB-C cable between the Spider and Pi. If you prefer a UART connection, please consult the fysetc documentation for the necessary configuration adjustments.
  • For DFU mode and flashing, please remove the display cables from Spider board. You should mark the cables with 1 and 2 to help with reconnection at later stage.

1. Enter DFU Mode

  1. First power off the board

  2. Set jumper on 5v pin and DC5V 5V Jumper

  3. Place jumper on BT0 to 3.3V pin DFU Jumper

  4. Connect USB cable to the board and RPI

  5. Power up the board with 24v

2. Build Firmware Image

  • Login to the Raspberry Pi via ssh

    username: pi
pass: raspberry

  • Run the following:

    sudo apt install make
cd ~/klipper
make clean
make menuconfig

  • In the menu structure there are a number of items to be selected.

    • Select “Enable extra low-level configuration options”
    • Set the micro-controller architecture is set to STMicroelectronics STM32
    • Set the Processor model to STM32F446
    • Set the Bootloader offset to 32KiB bootloader
    • If your Spider was made prior to 2021/06/23, set the Bootloader offset to 64KiB bootloader
    • Set the Clock Reference to 12 MHz crystal
    • Set the Communication interface to USB (on PA11/PA12) (note: see Fysetc documentation if you intend to use UART rather than USB) Spider Klipper Menu Config

  • Once the configuration is selected, press q to exit, and “Yes” when asked to save the configuration.

  • Run the command

    make

  • The make command, when completed, creates a firmware file klipper.bin which is stored in the folder /home/pi/klipper/out.

3. Firmware Installation

  • From your ssh session, run 
    lsusb
    and find the ID of the DFU device.
  • Run command below replacing 1234:5678 with the ID from the previous step 
    make flash FLASH_DEVICE=1234:5678

4. Exit DFU Mode

  • Power off the Spider
  • Remove the jumper from BT0/3.3V
  • Power up the Spider
  • You can confirm that the flash was successful by running 
    ls /dev/serial/by-id

If the flash was successful, this should now show a klipper device, similar to: Serial of Device

You will need to write that serial down and use it in printer.cfg as this is your device specific ID! You should power down the printer and connect display cables to Spyder now.

Next: Klipper configuration
