FlyOS-Fast System Introduction

Overview

FlyOS-Fast is a lightweight Linux system specifically optimized for 3D printing, providing a stable and efficient operating environment for the Fly series of host platforms.

Core Features

🏗️ System Architecture

• Single User Mode: Minimalist design, supports only the root user, ensuring system security and stability
• File System Optimization: Only /etc and /data directories are writable; core directories are read-only, significantly reducing the risk of power outage damage
• Fast Boot: Optimized boot process, completes KlipperScreen startup within 30 seconds

Software Ecosystem

• Complete Pre-installed Ecosystem: Includes Klipper, RRF, Mainsail, Fluidd, Moonraker, KlipperScreen, and other mainstream services
  • Targeted Optimization: We have performed specific optimizations for core services such as Klipper, Mainsail, Fluidd, Moonraker, and KlipperScreen to enhance system stability and printing performance
  • Important Warning: Do not manually upgrade or replace these services, manual switching will invalidate targeted optimizations and may affect system stability and feature compatibility
  • Version Timeliness Guarantee: All service components integrated during system packaging are the latest official versions at the time of build, with a version delay controlled within 48 hours
  • Build Mechanism: During the system image compilation phase, the latest stable versions are pulled from the official repositories of each service for integration
  • Smart Update Strategy: Any modified files or repositories will skip the update and retain the current version
  • Notes: Due to time required for system build and testing, the service versions integrated into the released system image may lag behind the official latest versions by up to two days, which is normal. For specific version requirements or questions, please contact technical support
• Streamlined Package Management: Removes traditional package managers, pre-installs necessary tools, maintaining system lightweightness
• Environment Optimization: Global Python environment simplifies plugin installation and command execution
