| Software notes | This printer is natively supported by Elegoo Slicer, a slicing software based on Orca Slicer that provides users with pre-configured, carefully optimized profiles designed to maximize both part detail and overall printing speed. Additionally, the machine's operating system is fully compatible with the most popular and community-endorsed third-party slicing software, such as Orca Slicer and Ultimaker Cura. The versatile onboard connectivity options include standard USB ports and a reliable dual-band Wi-Fi module (operating at 2.4 GHz and 5 GHz). This infrastructure enables effortless remote monitoring and comprehensive control of the printing process via its network interface and the built-in chamber camera, greatly streamlining daily workflow management. | 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 Elegoo Centauri Carbon 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.»
