Software notes The printer operates with Klipper firmware pre-installed on a 64-bit ARM processor, enabling advanced standard features like input shaping and pressure advance. The user interface is managed via a removable capacitive touchscreen and a dedicated web interface (Fluidd or Mainsail) for remote control and monitoring via Wi-Fi or LAN connection. For file preparation, the machine is compatible with major slicers on the market, including Elegoo Cura (bundled by the manufacturer), UltiMaker Cura, PrusaSlicer, and OrcaSlicer. The QIDI X-Smart 3 is primarily managed via QIDI Slicer, a proprietary software based on the latest versions of PrusaSlicer, optimized to fully leverage the machine's high speeds and CoreXY structure. The interface offers both a beginner mode and an advanced mode for granular control of parameters. The printer comes with pre-installed Klipper firmware, allowing advanced users direct access to the Fluidd web interface for real-time monitoring, calibration, and macro customization. Nevertheless, compatibility is guaranteed with the most popular third-party slicing software, including Ultimaker Cura, Simplify3D, and standard PrusaSlicer, ensuring a flexible and adaptable workflow.
