The ELEGOO x EMOJI Centauri Carbon 2 is a new multi-colour 3D printer featuring a 350° high-temperature nozzle end, a 121-point automatic levelling system, and an enclosed top chamber, according to hardware testing. While reviewers note that the machine delivers solid print quality and sturdy hardware, persistent software bugs and network connectivity drops create significant hurdles for remote operation.
Hardware Design and Enclosed Printing Performance
The Centauri Carbon 2 features a closed-bed design measuring 256x256x256 mm, providing a suitable space for larger prints like statues and helmet parts, according to testing data. This enclosed layout represents a notable shift from the open bed of the ELEGOO Neptune 4 Pro. When the door remains closed, the printer operates at roughly 45 dB on its default Balanced mode, measured via a smartphone sound-level meter app. Users can toggle to Sport or Ludicrous modes to accelerate output, though reviewers warn that higher speeds induce printer shaking and compromise the smoothness of finished models.
Pro Tip: Stick to Balanced mode for routine jobs. While Ludicrous mode increases printing velocity, the resulting mechanical vibration degrades surface finish quality on detailed prints.
Multicolour Capabilities and Emoji-Themed Aesthetics
Developed in collaboration with EMOJI, the printer includes an emoji-branded style plate, a unique themed case, and a custom user interface. The dual-sided build plate combines a standard textured bed with an EMOJI-branded smooth plate that imprints an emoji pattern onto the bottom of printed objects. The multicolour printing module sits on the right side of the machine, utilizing a straightforward filament-feeding system equipped with RFID support to automatically identify compatible spools. A thermal cover sits over this hub, maintaining the enclosed printing environment.
Reviewers point out that setting up the emoji-branded build plate requires creating a specific preset inside the ELEGOO Slicer software to support multi-bed printing—an oversight that can lead to failed prints if missed.
Component Upgrades: Cameras, Nozzles, and Clog Detection
Internal hardware improvements address several limitations found in the previous generation of the device. The updated real-time camera provides reliable video feeds viewable through the app, PC, and Mac, marking a clear upgrade from the original model’s time-lapse-only system. The newly designed nozzle reaches a maximum temperature of 350℃—up from 320℃—which aids layer adhesion during high-speed runs, though testers observed occasional light filament stringing. Furthermore, the inclusion of a clog detection sensor actively halts problematic print jobs before permanent damage occurs, safeguarding complex multi-colour projects.
Did You Know? The Centauri Carbon 2 incorporates a 121-point automatic levelling system that runs prior to each print, eliminating the need for manual Z-axis adjustments.
Software Instability and Network Dropouts
Despite robust mechanical performance, testers identified significant frustration points regarding software navigation and network reliability. The ELEGOO Slicer interface features cumbersome menus that make locating specific settings difficult. Additionally, file transfers and remote camera monitoring frequently fail unless the printer undergoes a manual reboot. Reviewers also reported that if the machine sits idle for a few days, it drops its network connection entirely, requiring manual intervention or advanced network adjustments such as IP reservation and band steering to resolve.
Frequently Asked Questions
