Ecosystem
Cloud dependency No No
Software notes The MK4S runs proprietary Prusa firmware based on Marlin, not GRBL. It is managed through PrusaSlicer (with over 180 official profiles included), Simplify3D, or Cura with community profiles. Files are loaded via USB, local network, or PrusaConnect and the Prusa mobile app; it is not compatible with LightBurn or LaserGRBL, being a filament printer. The machine can run fully offline with no cloud dependency, and receives regular firmware updates along with pre-tuned profiles for Prusament materials. 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.
