Firmware Flashing Instructions

How to Determine Which Firmware You Need

Caution

• Note: Since the C8 is an integrated motherboard for both upper and lower controllers, please ensure you select the USB firmware unless you are using a CAN tool board!!!
• When using a CAN tool board, be sure to select CAN bridge firmware

• USB Firmware
  • Advantages: Most commonly used connection method for 3D printers, reliable and stable communication
  • Disadvantages: Multiple USB devices may affect data transmission
• USB Bridge Firmware
  • Advantages: Allows multiple devices to be connected simultaneously without occupying USB ports. Only use this firmware when using a CAN tool board
  • Disadvantages: The first compilation and flashing of the firmware may be more troublesome

DIP Switch Introduction

Tip

FLY C8 connects to the upper controller via DIP switches. Incorrect DIP switch positions will prevent normal operation.

Important

Please note that the DIP switches must be set to their specified positions for proper connection to the upper controller.

Connecting to the Onboard Upper Controller

• Turn DIP switches 1 and 2 to the right to connect the lower controller to the upper controller via the built-in USB
