| Cloud dependency | No | No |
| Software notes | Compatible with Bambu Studio (OrcaSlicer-derived) and OrcaSlicer. Supports LAN mode for cloud-free printing. Does not run native Klipper. | 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. |
