Elegoo Centauri Carbon vs Elegoo Neptune 4 Pro
Technical comparison · Fused filament fabrication (FFF/FDM)
Two Elegoo printers with opposite approaches: the Centauri Carbon is an enclosed CoreXY with optional multicolor, the Neptune 4 Pro an open cartesian with Klipper preinstalled, at 299 € against between 300 and 450 €. It matters to anyone deciding whether they need an enclosed chamber and colors, or control through Fluidd or Mainsail.

| 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 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
- Chamber: enclosed on the Centauri Carbon, open on the Neptune 4 Pro → the Neptune works exposed to workshop air.
- Colors: up to 4 with the accessory against one → multicolor is only possible on the Centauri Carbon.
- Interface: Klipper with Fluidd or Mainsail on the Neptune 4 Pro; Elegoo Slicer, Wi-Fi and internal camera on the Centauri Carbon → two different ways to control a print remotely.
- Volume: 256 × 256 × 256 mm against 225 × 225 × 265 mm → more bed area on the Centauri Carbon, 9 mm more height on the Neptune 4 Pro.
Which one to choose
Choose Centauri Carbon if…
Prints in an enclosed chamber, with the internal camera to follow the job remotely over Wi-Fi, and the option to move to multicolor with up to 4 colors using the accessory. You spend more, and multicolor is not built in.
Choose Neptune 4 Pro if…
Anyone printing in one color who wants Klipper preinstalled, run from a browser with Fluidd or Mainsail, with files sent over a network cable, for 299 €. You give up the enclosed chamber and multicolor, and the bed is narrower, though it is taller.
