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, you must select the USB firmware unless you are using a CAN tool board!
• When using a CAN tool board, you must select the CAN bridge firmware.
• RS232 does not require flashing any firmware on the mainboard, but the corresponding tool board needs to have the RS232 firmware flashed.

• USB Firmware
  • Advantages: The most commonly used connection method in 3D printers, reliable and stable communication.
  • Disadvantages: Multiple USB devices may affect data transmission.
• CAN Bridge Firmware
  • Advantages: Can connect multiple devices simultaneously without occupying USB ports. Only use this firmware 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. Incorrect DIP switch positions may prevent the upper computer from connecting to the lower computer. Please pay close attention!!!
