Software notes The X2D uses Bambu Studio as its official software, available for Windows, macOS, and Linux. It also accepts standard G-code from third-party slicers such as PrusaSlicer, SuperSlicer, and Cura, though some advanced features — including automatic calibration and dual-nozzle workflow management — are only fully supported within Bambu Studio. 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 X2D if…

you value max print speed, maximum colors and closed chamber. «The rated maximum speed indicates the theoretical hardware limit, not the everyday working speed. Faster machines reduce print times on simple geometries, but real-world speed depends on material, geometry, required surface finish, and slicer settings. Values above 200–300 mm/s are meaningful only on machines with CoreXY kinematics, active input shaping, and a stiffened mechanical frame.»

See the X2D sheet →

Choose Neptune 4 Pro if…

you value price and native klipper. «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.»
