| Software notes | Compatible with the main slicers on the market. It supports cloud connectivity via the Anycubic app and Wi-Fi for remote monitoring, while still allowing offline use via USB. | 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. |
