🚀 Quick Start

🎯 Guide Objective: Complete the system deployment and firmware flashing of the Fly-Gemini motherboard within 30 minutes, making it ready to connect to Klipper for basic testing.
✅ Completion Criteria: Access the Klipper interface via a web browser and successfully connect to the Fly-Gemini motherboard.

📍 Important Notes
  • 📦 Required Accessory: The Fly-Gemini must be used with a Fly-M2WE or TF Card, otherwise the system will not boot
  • ⚡ Power Requirements: Input voltage range 12V-24V, do not exceed this range
  • 🔌 Safe Operation: Ensure the power is disconnected before any wiring operations! When flashing firmware, also follow the guide's instructions
  • 🔧 Tool Preparation: Prepare basic tools such as screwdrivers and data cables in advance

📦 Step 1: Prepare Tools and Resources​

📝 Included Content
  • MobaXterm (for connecting to the host computer)
  • CH340 (serial port driver for system connection)
  • Panasonic_SDFormatter (for formatting the TF card)
  • SetupSTM32CubeProgrammer (for flashing firmware to the slave computer)

🖥️ Step 2: Install System and Basic Configuration​

1. Flashing System Image​

2. System Basic Configuration​

3. Network and Remote Connection​

4. Display Device Configuration​



📝 Instructions for this Step
  • Ensure the TF card or M2WE is correctly formatted before flashing the image
  • The first system boot may take 3-5 minutes, please be patient
  • Default SSH login credentials: username: root, password: mellow
  • Screen configuration only required if a screen device is present

🔌 Step 3: Flash Firmware and Device Identification​

Why is this step necessary? The previous step installs the operating system for the host computer (compute module). This step flashes the Klipper firmware for the slave computer (Fly-Gemini control board itself); both must be paired to function.

1. Firmware Description and DIP Switch Selection​

2. Flash USB Firmware or CAN Bridge Firmware​

  • Choose the appropriate firmware to flash based on your connection method
📝 Instructions for this Step
  • Ensure the DIP switch is set correctly on the motherboard when flashing firmware; otherwise, the device will not be recognized
  • The device ID is essential information required in the Klipper configuration, please obtain it correctly
  • If flashing fails, try flashing the BL firmware first, then the main firmware

🛠️ Step 4: Hardware Connection and Interface Configuration​

1. Basic Hardware Connection​

2. Klipper Reference Configuration​

3. External Driver Connection and Configuration (Optional)​

4. Motherboard Precautions​

📝 Instructions for this Step
  • Strongly recommended: Ensure the power is completely disconnected before any wiring operations
  • Please confirm the correct power polarity; reversing it may damage the motherboard
  • Refer to your printer's frame diagram for the motor wiring sequence
  • Check the thermocouple connection before heating the heated bed and hotend

📈 Step 5: Extended Features and Advanced Configuration (Optional)​

The following features can be configured as needed after completing the basic setup and ensuring the printer operates normally:

📝 Extended Features and Advanced Configuration

Camera Usage​

External Tool Board​

Resource Download​

  • It is recommended to configure and test extended features one by one to avoid changing too many parameters at once
  • Camera configuration requires an additional USB camera device
  • Resonance compensation requires an accelerometer sensor
  • Tool board connection is suitable for multi-toolhead 3D printers
