Software notes The printer operates with Klipper firmware pre-installed on a 64-bit ARM processor, enabling advanced standard features like input shaping and pressure advance. The user interface is managed via a removable capacitive touchscreen and a dedicated web interface (Fluidd or Mainsail) for remote control and monitoring via Wi-Fi or LAN connection. For file preparation, the machine is compatible with major slicers on the market, including Elegoo Cura (bundled by the manufacturer), UltiMaker Cura, PrusaSlicer, and OrcaSlicer. PrusaSlicer (optimized) and Prusa Connect for remote control. The machine accepts G-code from any slicer (Cura, Simplify3D) and communicates via USB, Ethernet or Wi-Fi using an open Marlin-based protocol. Compatible with OctoPrint and offline management. Does not require a Prusa account to print, unlike machines with proprietary firmware that block features without connection.

Which one to choose

Choose Elegoo Neptune 4 Plus if…

you value price, work area 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.»

Choose Original Prusa MK4S if…

you value multicolor printing. «Multicolor printing produces objects with distinct color zones without manual post-print painting. The most common method involves swapping the filament before depositing different color areas. Result quality depends on the precision of the swap and how transitions are managed, since mixed-material purge is always involved. This parameter should be assessed together with the maximum number of colors and whether an external accessory is required.»
