This is my klipper config for a Voron Trident (300 mm) with a FYSETC Spider v2.2. I use a Raspberry Pi 4B running Moonraker and Klipper via KIAUH.

I do not include the firmware; please compile your own.

VT.1376

All printed parts done on my old Ender 3:

Primary: Priline CF-PC (some hotend parts started warping so I replaced them with ABS versions)

Accent: PC-PETG Blend

Non chamber parts: GF-PETG

1. Ensure klipper is updated to the latest version.
2. Access the klipper directory, typically ~/klipper
3. make clean
4. make menuconfig
5. Select the options according to the microcontroller.
6. make
7. Compiled firmware is located in out/klipper.bin

• Micro-controller Architechture (STMicroelectronics STM32)
• Processor model (STM32F072)
• Bootloader offset (No 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))
• (1000000) CAN bus speed

1. Ensure printer is cooled down.
2. Unload filament.
3. Turn off power via main AC inlet switch.
4. Remove power cord and ethernet cable.
5. Remove any loose objects from top of printer.
6. Remove top handles (2x M3 screws, 2.5 mm hex drive each).
7. Remove Bento filter unit.
8. Turn entire printer upside down, with the front facing away.
9. Remove HULA feet.
10. Remove electronics enclosure latches (4x, M3 screws, 3.5 mm hex drive).
11. Swing open cover.

Note: Power may be left on and physical reset button used to reboot microcontroller.

1. Access the electronics enclosure, following procedure above.
2. Ensure all power is off.
3. Ensure 5V select jumper is in lower position (DC5V).
4. Place jumper on BT0 and 3.3V pins. Could also use tweezers.
5. Turn on power via main AC inlet switch.
6. Verify board is in DFU mode by checking the output of lsusb.
7. Upload new firmware with dfu-util -R -a 0 -s 0x08008000:leave -D ~/klipper/out/klipper.bin
8. Turn off power via main AC inlet switch.
9. Remove BT0 jumper.
