Elegoo Centauri Carbon 2 Combo vs Elegoo Neptune 4 Plus
Technical comparison · Fused filament fabrication (FFF/FDM)
Anyone who wants an FDM printer that switches between colors on the same part, with an enclosed chamber, should look at the Centauri Carbon 2 Combo. Anyone who needs a larger build plate at a lower starting price, and can live with a single color, should look at the Neptune 4 Plus.

| 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 printer operates with Klipper firmware pre-installed on a 64-bit ARM processor, enabling advanced standard features like input shaping and pressure advance. The user interface is managed via a removable capacitive touchscreen and a dedicated web interface (Fluidd or Mainsail) for remote control and monitoring via Wi-Fi or LAN connection. For file preparation, the machine is compatible with major slicers on the market, including Elegoo Cura (bundled by the manufacturer), UltiMaker Cura, PrusaSlicer, and OrcaSlicer. |
The differences that matter
- Colors: 4 on the Centauri Carbon 2 Combo, 1 on the Neptune 4 Plus → the CANVAS system prints multicolor parts without manual filament changes.
- Build area: 256×256 mm vs 320×320 mm → the Neptune 4 Plus fits larger parts or more parts on the same plate.
- Z height: 256 mm vs 385 mm → the Neptune 4 Plus prints taller vertical objects in one piece.
- Price: €439 vs about €350 → the Neptune 4 Plus costs less to buy.
Which one to choose
Choose Centauri Carbon 2 Combo if…
The Centauri Carbon 2 Combo's CANVAS system prints logos or miniatures with multiple colors on the same part, without manually swapping filament; the chamber is enclosed. The trade-off is a smaller build plate and a higher starting price.
Choose Neptune 4 Plus if…
The Neptune 4 Plus gives more room on a larger build plate, useful for bigger single parts or tall vertical prints, and costs less to buy. Klipper firmware comes pre-installed, managed from the touchscreen or a web interface. You give up the enclosed chamber and multicolor printing.
