FlyOS-Fast System Introduction

Overview

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

Core Features

System Architecture

• Single-User Mode: Minimalist design, only supports 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 failure damage
• Fast Startup: Optimized boot process, completes KlipperScreen startup within 30 seconds

Software Ecosystem

• Complete Pre-installed Ecosystem: Built-in mainstream services including Klipper, RRF, Mainsail, Fluidd, Moonraker, KlipperScreen
  • 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 the targeted optimizations and may affect system stability and functional compatibility
  • Version Timeliness Guarantee: All service components integrated into the system 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 each service's official repository for integration
  • Smart Update Strategy: Any modified files or repositories will skip the update and retain the current version
  • Notes: Due to the time required for system building and testing, the version of services integrated into the released system image may lag behind the official latest version by up to two days - this is normal. Please contact technical support for specific version requirements or inquiries
• Streamlined Package Management: Removed traditional package managers, pre-installed necessary tools to maintain a lightweight system
• Environment Optimization: Global Python environment, simplifying plugin installation and command execution
