Quick Navigation​

1. Preparation​

Hardware Checklist:

  • Mainboard: Fly-D8-Pro-H723
  • Host:
    Host Compatibility Notice
    • Recommended Models: Fly-PI-V3, Raspberry Pi 4/5, and other standard hosts
    • Unsupported Models: Redmi phones, WiFi dongles & set-top boxes, various non-standard modified hosts
    • Important Note: Using non-standard hosts may lead to system instability, functional anomalies, or inability to operate normally.
  • Data Cable: One Type-C data cable
  • Connection Method: Only use Type-C to connect to the host
  • Power Supply: 12V‑24V power adapter (ensure voltage is within range)
  • Computer: Windows PC (or other computer capable of using SSH tools)
Preparation Notes
  • It is recommended to use a reliable quality Type-C data cable; poor-quality cables may cause unstable connections.
  • The power adapter wattage must meet the printer's requirements; ≥300W is recommended.
  • Ensure the host has a Klipper-related system (e.g., MainsailOS) installed.

2. User Guide & Important Notes​

Core Principle: Most issues are caused by inconsistent configuration, connection, or power supply. Below are important notes for the Fly-D8-Pro-F407:

3. Firmware Flashing & Device Identification​

1. Firmware Description & Mode Selection​

2. Flashing USB or CAN Firmware​

Choose the corresponding firmware based on the connection method:
