Flash Klipper USB firmware with Katapult over USB
- Find the Serial ID
ls /dev/serial/by-id/ -
Copy the ID containing ‘STM32F407’ 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.407zg flash FLASH_DEVICE= {Your serial ID here } - Example
make KCONFIG_CONFIG=config.407zg flash FLASH_DEVICE=/dev/serial/by-id/usb-katapult_stm32f407xb_170038000650314D35323820-if00
- Your Fly-407ZG should now have klipper firmware loaded and be ready to use.
