| Software notes | The system relies on an open ecosystem thanks to the motherboard with pre-installed Klipper. Users can manage the machine both through the 4.3-inch capacitive touchscreen interface and via local network using the integrated web interface (Fluidd). Elegoo provides its own customized version of the Cura slicer, but the printer remains fully compatible with most third-party slicers such as PrusaSlicer, OrcaSlicer, and Simplify3D. Native support for Wi-Fi and LAN connectivity facilitates sending and monitoring G-code files without the need for physical media. | 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. |
