Quick Navigation

1. Preparation

Hardware Checklist:

  • Mainboard: Fly-D7
  • Host Computer:
    Host Compatibility Note
    • 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: Must 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, high-quality Type-C data cable; poor-quality cables may cause unstable connections.
  • The power adapter's wattage must meet the printer's requirements; a minimum of 300W is recommended.
  • Ensure the host computer has a Klipper-related system (e.g., MainsailOS) installed.

2. Usage Guide & Important Notes

Core Principle: Most issues are caused by configuration, connection, or power supply inconsistencies. Below are important notes for the Fly-D7:


3. Firmware Flashing & Device Identification

1. Firmware Explanation & Mode Selection

2. Flashing USB or CAN Firmware

Choose the corresponding firmware based on the connection method:

Step Explanation
  • Device Identification: After flashing, be sure to record the device ID/UUID, as it is essential for Klipper configuration.
  • Fallback Solution: If flashing fails, you can try flashing the BL firmware first.

4. Hardware Connection & Klipper Configuration

Includes:

  • Explanation of mainboard interface functions
  • Wiring methods for motors, heaters, sensors, etc.
  • Klipper reference configuration files

Connection Safety Tips
  • Before any wiring operation, ensure the power is completely disconnected.
  • Confirm the power polarity is correct; reversing it may damage the mainboard.
  • Refer to your printer frame diagram for motor wiring sequence.
  • Check thermocouple connections before heating the heated bed and hotend.

5. Advanced Features & Advanced Configuration (Optional)

Optional Features:

  • Marlin Firmware: Use Marlin firmware as an alternative to Klipper.
  • External Toolboard: Supports multi-toolhead systems.
