| Software notes | Kobra OS (based on Klipper) featuring a 4.3-inch touchscreen interface. Compatible with Anycubic Slicer for color management and Wi-Fi connected for remote monitoring via app. The integrated ACE Pro system automatically handles filament changes and active drying. | 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. |
