Quick Navigation​

1. Preparations​

Hardware Checklist:

  • Tool Board: Fly-SHT36-V3
  • Host Computer:
    Host Computer Compatibility Note
    • Recommended Models: Fly-PI-V3, Raspberry Pi 4/5, and other standard host computers
    • Unsupported Models: Redmi phones, WiFi dongles, set-top boxes, and various non-standard modified host computers
    • Important Note: Using modified host computers may lead to system instability, functional abnormalities, or inability to operate normally
  • Data Cable: One Type-C data cable
  • Connection Method (Choose One):
    • CAN Connection: Requires a UTOC module or a motherboard flashed with USB-to-CAN bridge firmware
    • RS232 Connection: Requires a UTOR module or a motherboard with native RS232 support (e.g., D8, D8-PRO, C8P)
  • Power Supply: 12V‑24V power adapter (ensure voltage is within range)
  • Computer: Windows PC (or other computer capable of using SSH tools)

2. User Guide and Important Notes​

Core Principle: Most issues are caused by configuration, connection, or power supply inconsistencies. Prioritize troubleshooting in the following order:

  1. Connection and Configuration: Ensure the DIP switch setting, firmware type, and the connection method in Klipper's [mcu SHT36] configuration are consistent (all CAN or all RS232).
  2. Power and Wiring: Confirm the supply voltage is normal and all cable connections are secure.
  3. Status Indicators: After powering on, check if the power and status LEDs are functioning normally.
