| Software notes | Equipped with Kobra OS, a Klipper-based firmware, controllable via a 4.3-inch touchscreen. Compatible with Anycubic Slicer and third-party software like OrcaSlicer. Features Wi-Fi for remote control via app. Multicolor printing requires the ACE Pro module, sold separately. | 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. |
