| Software notes | The proprietary Elegoo OS, built on Klipper architecture, manages full-auto calibration routines and AI-assisted monitoring. The machine is primarily supported by Elegoo Slicer (an Orca Slicer derivative), ensuring optimal control over material profiles and dynamic color changes. Users can also natively use Orca Slicer or export G-code from third-party alternatives like Cura. The intuitive touchscreen and Wi-Fi connectivity enable seamless remote management and direct job queuing over the local network. | 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. |

Which one to choose
Choose Centauri Carbon 2 if…
you value max print speed, maximum colors and closed chamber. «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 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.»
