Software notes It runs Kobra OS (based on Klipper) with a 4.3-inch touch interface. It is compatible with Anycubic Slicer for color management and connects via Wi-Fi for remote monitoring through the app. 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.
