| Software notes | Equipped with Kobra OS, a Klipper-based firmware, controllable via a 4.3-inch touchscreen. Compatible with Anycubic Slicer and third-party software like OrcaSlicer. Features Wi-Fi for remote control via app. Multicolor printing requires the ACE Pro module, sold separately. | 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. |

Which one to choose
Choose Kobra 3 Max 3D Printer if…
you value work area, maximum z height and maximum colors. «The Z height determines how tall a part the machine can produce in one print. Vertical objects such as vases, load-bearing structures, or casting patterns require a high Z travel. A lower value does not affect quality but forces the user to split or reorient the model. Z height should be considered alongside the XY surface to assess total usable build volume.»
Choose Neptune 4 Pro if…
you value price and 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.»
