| Software notes | Compatible with major third-party slicers such as PrusaSlicer and Cura. It features Wi-Fi connectivity managed through the Anycubic app, while still allowing offline use via USB. | The system relies on an open ecosystem thanks to the motherboard with pre-installed Klipper. Users can manage the machine both through the 4.3-inch capacitive touchscreen interface and via local network using the integrated web interface (Fluidd). Elegoo provides its own customized version of the Cura slicer, but the printer remains fully compatible with most third-party slicers such as PrusaSlicer, OrcaSlicer, and Simplify3D. Native support for Wi-Fi and LAN connectivity facilitates sending and monitoring G-code files without the need for physical media. |
The differences that matter
- Native Klipper: Neptune 4 Max yes, Kobra 2 Max no
- Max nozzle temperature: Kobra 2 Max 260 °C vs Neptune 4 Max 300 °C — Neptune 4 Max wins (+15%)
- Max bed temperature: Kobra 2 Max 90 °C vs Neptune 4 Max 85 °C — Kobra 2 Max wins (+6%)
Which one to choose
Choose Kobra 2 Max if…
you value max bed temperature. «A heated bed reduces the thermal gradient between the part and the environment, limiting warping and delamination. Up to 60 °C covers PLA and flexible materials. Between 80 and 110 °C it enables PETG, ABS, and ASA. Above 110 °C it is necessary for PC and high-temperature technical materials. Bed temperature should be evaluated alongside nozzle temperature: a high-rated bed adds little value if the nozzle cannot reach the corresponding threshold.»
Choose Neptune 4 Max if…
you value native klipper and max nozzle temperature. «Klipper is an open-source firmware that offloads trajectory calculations from the microcontroller to a host computer, enabling all advanced features including input shaper and pressure advance. Native support eliminates the need to replace the firmware, a process that voids the warranty on some machines. Relevant for users who intend to tune advanced parameters; for basic use the difference from Marlin is minimal.»
