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 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 differences that matter

  • Enclosed chamber against open → only the Centauri Carbon 2 is enclosed; the Neptune 4 Pro prints in the open.
  • Up to 4 colours against 1 → multicolour exists only on the Centauri Carbon 2, with its accessory.
  • Bed 256 × 256 mm against 225 × 225 mm → parts wider than 225 mm fit only on the Centauri Carbon 2.
  • 374 € against 299 € → the Neptune 4 Pro costs 75 € less.

Which one to choose

Choose Centauri Carbon 2 if…

you print in an enclosed chamber and in several colours, up to 4 with the accessory it needs. The bed is 256 × 256 mm and the nozzle reaches 350 °C against 300 °C (stated values). You accept about 75 € more and a 19.35 kg machine.

See the Centauri Carbon 2 sheet →

Choose Neptune 4 Pro if…

you print single-colour in the open and want the lowest outlay: about 299 €, roughly 75 € less, for 8.9 kg. You give up the enclosure, multicolour, and 31 mm of bed per side.
