Artillery M1 Pro S1 vs Prusa Research MK4S kit
Technical comparison · Fused filament fabrication (FFF/FDM)
Two filament printers with a 250–260 mm bed and opposite ideas about firmware: open Klipper against Prusa's Marlin-based firmware. The price gap matters: the Artillery costs about €485 less.

| Software notes | Native Klipper firmware with Moonraker API. Recommended web interfaces: Mainsail or Fluidd. Compatible with standard slicers: UltiMaker Cura, PrusaSlicer, OrcaSlicer, IdeaMaker, Simplify3D. No proprietary software required. Unlimited root access: the user can modify configurations without restrictions. | The MK4S runs proprietary Prusa firmware based on Marlin, not GRBL. It is managed through PrusaSlicer (with over 180 official profiles included), Simplify3D, or Cura with community profiles. Files are loaded via USB, local network, or PrusaConnect and the Prusa mobile app; it is not compatible with LightBurn or LaserGRBL, being a filament printer. The machine can run fully offline with no cloud dependency, and receives regular firmware updates along with pre-tuned profiles for Prusament materials. |
The differences that matter
- About €334 vs €819 → €485 apart, which is another machine or a year of filament.
- Bed 260×260 mm and Z 260 mm vs 250×210 mm and Z 220 mm → on the MK4S a part taller than 220 mm does not print.
- Klipper with root access vs Prusa firmware on Marlin → on the Artillery you change configurations freely, on the MK4S you rely on the official profiles.
Which one to choose
Choose M1 Pro S1 if…
You want to get your hands into the machine: Klipper with Moonraker, Mainsail or Fluidd interface, unrestricted root access, and a slicer of your choice among Cura, PrusaSlicer, OrcaSlicer, IdeaMaker and Simplify3D. The bed is 260×260 mm with 260 mm of height, and you spend around €334 against €819. The trade-off: tuning and profiles are yours to verify, without the ready-made Prusament profiles that come with the MK4S.
Choose MK4S kit if…
You print every day and want the machine to work without tinkering: PrusaSlicer with over 180 official profiles, regular firmware updates, PrusaConnect and the app, fully offline use. You pay about €485 more for a 250×210 mm bed and 220 mm of height, and multicolor needs an accessory (up to 5 colors).
