Firmware flashing instructions
- The Micro4 defaults to firmware flashing via Katapult using a USB connection.
Firmware Compilation and Burning
Please first select the firmware type you intend to burn. Only after making a selection will the corresponding compilation and burning steps be displayed.
Bootloader Recovery (Unbricking)
The FLY-Micro4 comes with Katapult pre-flashed from the factory. Do not re-flash the firmware on this page during normal use or when updating Klipper firmware; this page is only for brick recovery after the Bootloader is damaged.
