| 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. | It comes with the proprietary Snapmaker Luban software, a free, unified application available for Windows, macOS, and Linux. Luban is tailored to fully utilize the independent dual extruders (IDEX), integrating ready-to-use profiles for various print modes (Copy, Mirror, Backup). Compatibility with major third-party slicers, such as Cura or PrusaSlicer, is also ensured via standard G-code export. Direct machine control is facilitated by the integrated Android-based touchscreen display and Wi-Fi connectivity for remote management. |
