| Software notes | The operating system is based on the open-source Marlin firmware, ensuring broad compatibility and stability for the user. The printer is supported by major slicing software on the market, such as Ultimaker Cura and PrusaSlicer, for which official preset profiles or easily configurable community profiles exist. Operational management is handled via a practical removable capacitive touchscreen, featuring a simple interface for manual control and monitoring. The machine operates entirely offline, reading G-code files via a MicroSD card or direct USB cable connection, without any dependency on cloud services or wireless networks. | 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. |

Which one to choose
Choose Neptune 3 Pro if…
you value price and maximum z height. «The Z height determines how tall a part the machine can produce in one print. Vertical objects such as vases, load-bearing structures, or casting patterns require a high Z travel. A lower value does not affect quality but forces the user to split or reorient the model. Z height should be considered alongside the XY surface to assess total usable build volume.»
Choose Neptune 4 Pro if…
you value max print speed, native klipper and input shaper. «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.»
