| Software notes | Native Klipper firmware with a 64-bit ARM 1.5 GHz processor. The printer is controlled via Wi-Fi from the Fluidd or Mainsail web interface, sending G-code from any slicer (Cura, PrusaSlicer, OrcaSlicer). No proprietary software required; USB/Type-C connection allows offline control. The user has full access to macros and advanced Klipper tuning, without hardware modifications. | Powered by CrealityOS, a Klipper-based firmware, it supports remote control via Wi-Fi or LAN and interfaces natively with Creality Print and other compatible slicers for advanced multi-color workflow management. |
