| Software notes | The machine is compatible with major slicing software on the market. The manufacturer recommends using Elegoo Slicer, specifically optimized to leverage the CoreXY kinematics, multi-color printing via the CANVAS system, and vibration compensation algorithms (Input Shaping). Alternatively, popular slicers like Orca Slicer and Cura can be used, offering broad flexibility to users who prefer established workflows. The integrated dual-band Wi-Fi connectivity allows direct transfer of G-code files to the 8 GB internal memory without physical cards, while the internal camera enables remote monitoring and time-lapse video recording, simplifying the management of the printing process even from a distance. | 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 differences that matter

Which one to choose
Choose Centauri Carbon 2 Combo 3D Printer 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.»
