Fly Host Computer Installation and User Guide

I. Preparation

1. Power Requirements

• Power Standard: An independent power adapter of 5V / 2A or higher must be used
• Prohibited Actions: Powering through the 3D printer motherboard interface is strictly prohibited, except for the following specific models
  • ✅ Supported Motherboard Power Models: C8, GEMINI, C5, C5V1.1, C8P
• Risk Warning: Insufficient power supply will lead to unstable device operation and frequent restarts. Long-term use may cause hardware damage

2. Storage Medium Selection

Storage Type	Compatible Devices	Key Notes
TF Card	Fully compatible	General solution, requires standard card reader
M2WE Solid State Card	Non-Lite/MINI-PAD series	Dedicated solution, requires M2SD programmer

Recommended TF Card Specifications:

• Capacity: 16GB–128GB (32GB/64GB recommended)
• Speed Class: Class10 or U1/U3
• Recommended Brands: SanDisk, Samsung, and other well-known brands

3. Burning Tool Preparation

• TF Card: Standard TF card reader
• M2WE Card: Dedicated M2SD programmer (required)

4. System Image Matching

Choose the corresponding system image based on the device's main control chip:

Main Control Chip	Compatible Device Models
H618	C8P, C5, C5-V1.1, PI-V3
H5	PI, PI-V2, GEMINI series, C8
H3	Lite2 series, MINI-PAD series

III. Device Booting and Connection

• SSH Connection Tutorial

1. Hardware Connection

• Insert the storage card with the system burned onto it
• Connect the independent power adapter
• Connect to the computer using a Type-C data cable

2. Serial Terminal Configuration

• Launch the MobaXterm software
• Create a new Serial session
• Select the CH340 serial port, baud rate 115200

3. System Boot Verification

• Observe the terminal log output after powering on
• A successful boot will display system operation information
• If no output appears, try pressing the Enter key to wake up the system

4. Network Configuration

After the system boots up, configure Wi-Fi connection via the command line

IV. Common Issues and Maintenance Guide

Boot Priority

• Issue: Boot sequence when both TF card and M2WE card are inserted
• Explanation: The system always prioritizes booting from the TF card, but the M2WE card's Wi-Fi function can still be used normally after booting
• Solution: It is recommended to insert only one system card during daily use to avoid confusion

Storage Card Selection

• Issue: How beginners can choose a storage card type
• Solutions:
  • Recommended Option: TF card (high compatibility, low cost, suitable for beginners)
  • Important Reminder: Using a TF card requires additional configuration of a Linux driver-free Wi-Fi module
  • Alternative Option: M2WE card has built-in Wi-Fi functionality but requires a dedicated programmer

M2WE Card Contact Issues

• Issue: Unstable recognition or failure to boot with the M2WE card
• Solutions:
  • Temporary solution: Reinforce the connection between the card and slot using a rubber band
  • Long-term solution: Install a dedicated fixing bracket

Device Maintenance Guide

1. Shutdown Procedure

• Always perform a normal shutdown via system commands
• Never disconnect the power directly, to avoid system damage

2. System Updates

• The system supports two update methods:
  1. Online Update: Automatically completed in the system background
  2. Manual Update: Download the update package locally and upload/install it via the system interface
• Please note that the traditional FAST system full-disk burning upgrade method still applies

3. Configuration Backup

• Regularly back up your printer configuration files to local storage devices
• Avoid configuration loss due to system issues

4. Power Management

• Must use an independent power supply
• Avoid power interference affecting device stability

5. Storage Card Protection

• Do not format the storage card again after system burning
• Prevent system file damage that could lead to boot failure

OTA Update Instructions

1. How to Perform an OTA Update

• Access your host machine's IP address in a browser, and append the port number :9998 to access the OTA update interface
  • Example: If your host machine's IP is 192.168.1.100, visit http://192.168.1.100:9998

2. Configuration File Safety

• OTA updates are specially designed to not overwrite or modify your personal configuration files

3. Important Notes During Update

• Ensure stable power supply during the update
• Unexpected power loss will cause the update to fail, and in severe cases, the system will need to be re-burned

4. Custom Code Handling

• If you have modified the Klipper configuration file or installed custom plugins
• The OTA update will automatically skip relevant files to preserve your modifications

5. Important Reminder: Firmware Update

• After each OTA update, manually compile the Klipper firmware and re-flash the microcontroller firmware
