Firmware Flashing Instructions

How to Determine Which Firmware You Need

Caution

Note: Since the C8P is an integrated mainboard with both host and controller functions, if you are not using a CAN tool board, you must select the USB firmware!
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 be flashed with RS232 firmware.

USB Firmware
- Advantages: The most commonly used connection method in 3D printers, offering reliable and stable communication.
- Disadvantages: Multiple USB devices may affect data transmission.
CAN Bridge Firmware
- Advantages: Allows connecting multiple devices simultaneously without occupying USB ports. Only use this firmware when using a CAN tool board.
- Disadvantages: The initial firmware compilation and flashing process can be more complicated.

The FLY C8P uses DIP switches to select the connection method between the host and the controller. If the DIP switch is set incorrectly, the host may fail to connect to the controller. Please pay close attention!!!

Important Notes

For normal use, set the DIP switch to the "UP" position.
When setting the DIP switch, push it all the way UP, otherwise the controller may not connect properly!!!
