Note

• D8 comes with the Katapult firmware pre-flashed

Firmware Burning Instructions

Important

• Mainboard firmware burning needs to be done through Katapult burning Klipper
• If you are sure that the mainboard has already been burned with Katapult, there is no need to burn the Katapult firmware at the end, as that is just a precaution in case the mainboard's Katapult firmware was not burned successfully
• You can quickly press the reset button twice to see if there is an LED blinking on the mainboard, if so, it means the mainboard has entered the Katapult firmware
