| Software notes | The machine is driven by Klipper firmware pre-installed on a proprietary 64-bit motherboard, ensuring rapid processing for advanced features like input shaping and pressure advance. The manufacturer provides a customized version of Cura (Elegoo Cura), but the printer is fully compatible with major third-party slicers such as PrusaSlicer and OrcaSlicer. Connectivity includes USB ports and a LAN network port, enabling remote management and direct print file transfers via the Fluidd or Mainsail web interfaces integrated into the system. | The printer runs Marlin firmware customized by Prusa, heavily influenced by Klipper and natively compatible with PrusaSlicer for tool-change management, Input Shaper, and Pressure Advance. Other slicers such as Cura or Simplify3D produce standard G-code but don't support tool changing or the segmented bed. The G-code protocol is open, and control via OctoPrint or Pronterface is possible. PrusaConnect and Wi-Fi are built in for remote management, while the absence of a locked proprietary ecosystem allows the use of third-party filaments and spare parts. |

Which one to choose
Choose Neptune 4 Pro if…
you value price, max print speed and native klipper. «The rated maximum speed indicates the theoretical hardware limit, not the everyday working speed. Faster machines reduce print times on simple geometries, but real-world speed depends on material, geometry, required surface finish, and slicer settings. Values above 200–300 mm/s are meaningful only on machines with CoreXY kinematics, active input shaping, and a stiffened mechanical frame.»
Choose Original Prusa XL Single-toolhead 3D Printer if…
you value work area, maximum colors and maximum z height. «The maximum number of colors indicates how many distinct color zones or materials can be used in one print without manual intervention. Two colors cover most practical uses, including soluble support. Higher values are useful for complex decorative models or color-coded prototypes. Each additional color increases print time due to transition purges, so the practical benefit should be weighed against the added time cost.»
