Firmware Flashing Instructions

How to Determine Which Firmware You Need

warning

• Note: Since the C8P is an integrated mainboard with both upper and lower computers, unless you are using a CAN tool board, you must choose the USB firmware!!!
• When using a CAN tool board, you must choose the CAN bridge firmware.
• RS232 does not require flashing any firmware on the mainboard, but the corresponding tool board needs to be flashed with RS232 firmware.

• USB Firmware
  • Advantages: The most commonly used connection method in 3D printers, reliable and stable communication.
  • Disadvantages: Multiple USB devices may affect data transmission.
• USB Bridge Firmware
  • Advantages: Can connect multiple devices simultaneously and does not occupy USB ports. This firmware is only required when using a CAN tool board.
  • Disadvantages: The initial compilation and flashing process can be more complicated.

DIP Switch Introduction

• The FLY C8P uses DIP switches to select the connection method between the upper and lower computers. If the DIP switch positions are incorrect, the upper computer may fail to connect to the lower computer. Please pay close attention!!!

Onboard DIP Switch Instructions

Important

• For normal use, please set the DIP switch to the upward position.
