| Software notes | Artillery OS, a Klipper-based system. Compatible with standard slicers like Cura, PrusaSlicer and OrcaSlicer via G-code. Supports Wi-Fi transfer, SD card and touchscreen control. Compared to closed platforms, it allows advanced adjustment of printing parameters, but lacks a native cloud ecosystem and requires manual slicer configuration. | 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. |
The differences that matter

- Native Klipper: Neptune 4 Pro yes, Artillery M1 Pro S1 no
- Multicolor printing: Artillery M1 Pro S1 yes, Neptune 4 Pro no
- Requires external accessory: Artillery M1 Pro S1 yes, Neptune 4 Pro no
Which one to choose
Choose Artillery M1 Pro S1 if…
you value closed chamber, work area and multicolor printing. «A closed chamber reduces thermal gradients around the part being built, limiting warping and cracking caused by rapid cooling in high-shrinkage materials such as ABS, ASA, and PC. It also shields the mechanism from drafts and airborne particles. A closed chamber is effectively necessary for technical materials; for PLA and PETG it is an advantage, not a requirement.»
Choose Neptune 4 Pro if…
you value native klipper and price. «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.»
