Elegoo Centauri Carbon 2 vs Qidi Tech Plus4
Technical comparison · Fused filament fabrication (FFF/FDM)
Two enclosed CoreXY printers with native Klipper and multicolor via accessory: the choice comes down to part size and the number of colors. The Centauri Carbon 2 costs between €349 and €399, the Plus4 €799.

| 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 relies on an architecture based on Klipper firmware, which provides advanced computational performance and native features like input shaping to reduce vibrations during high-speed movements. Users can interface via the integrated 5-inch touchscreen or through the standard Klipper web interface. The recommended official slicing software is QIDI Studio, a program derived from PrusaSlicer and Orca Slicer, optimized to leverage the machine's profiles and proprietary print parameters. However, the system maintains an open approach and is fully compatible with third-party slicers such as Orca Slicer, PrusaSlicer, and Cura, ensuring maximum flexibility in the daily workflow. |
The differences that matter
- 305×305 mm bed vs 256×256 mm → wider single parts fit on the Plus4.
- Up to 16 colors vs 4 → beyond four shades, only the Plus4 goes there.
- Nozzle up to 370 °C vs 350 °C, manufacturer's declared values → materials that need more than 350 °C are for the Plus4 only.
Which one to choose
Choose Centauri Carbon 2 if…
Your parts fit in 256×256 mm and up to 4 colors is enough: you spend about half as much. The trade-off is the smaller bed and a nozzle that stops at 350 °C.
Choose Plus4 if…
You print parts up to 305×305 mm, need up to 16 colors, or work with materials that call for a nozzle up to 370 °C and a bed at 120 °C. The trade-off is the outlay, €400 to €450 more, and 27 kg against 19.35 kg.
