🚀 Quick Start

🎯 Guide Objective: Complete system deployment and firmware flashing for the Fly-C8 mainboard within 30 minutes, bringing it to a state where it can connect to Klipper and perform basic tests.
✅ Completion Criterion: Access the Klipper interface via a web browser and successfully connect to the Fly-C8 mainboard.

📍 Important Notes
  • 📦 Required Accessories: Fly-C8 must be used with either Fly-M2WE or a TF card, otherwise the system will not boot.
  • ⚡ Power Requirements: Input voltage range is 12V-24V. Do not exceed this range.
  • 🔌 Safe Operation: Always disconnect power before performing any wiring operations! When flashing firmware, please follow the guide's instructions.
  • 🔧 Tool Preparation: Prepare basic tools such as screwdrivers and data cables in advance.

📦 Step 1: Prepare Tools & Resources​

📝 Included Content
  • MobaXterm (for connecting to the host computer)
  • CH340 (serial port driver for system connection)
  • Panasonic_SDFormatter (for formatting TF cards)
  • SetupSTM32CubeProgrammer (for flashing the lower-level controller firmware)

🖥️ Step 2: Install System & Basic Configuration​

1. System Image Flashing​

2. System Basic Configuration​

3. Network & Remote Connection​

4. Display Device Configuration​



📝 Step Description
  • 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 credentials: username: root, password: mellow.
  • Screen configuration is only necessary if you have a screen device.

🔌 Step 3: Flash Firmware & Device Identification​

Why is this step needed? The previous step installed the operating system for the host computer (computing module). This step is for flashing the Klipper firmware onto the lower-level controller (the Fly-C8 mainboard itself). Both need to be paired to work.

1. Firmware Explanation & DIP Switch Selection​

2. Flash USB Firmware or CAN Bridge Firmware​

  • Choose to flash the corresponding firmware based on your connection method.
📝 Step Description
  • When flashing firmware, ensure the mainboard's DIP switch is set to the correct position; otherwise, the device may not be recognized.
  • The Device ID is essential information for Klipper configuration; please obtain it correctly.
  • If flashing fails, try flashing the BL firmware first, then flash the main firmware.

🛠️ Step 4: Hardware Connection & Interface Configuration​

1. Basic Hardware Connections​

2. Klipper Reference Configuration​

3. External Driver Connection & Configuration (Optional Feature)​

4. Mainboard Precautions​

📝 Step Description
  • Strongly Recommended: Ensure power is completely disconnected before performing any wiring operations.
  • 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.

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

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

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