| Software notes | Operated via AnycubicSlicer and compatible with the proprietary cloud app. It leverages a Klipper-based firmware, natively integrating Input Shaping algorithms to reduce vibrations at high speeds. | Native Klipper firmware with a 64-bit ARM 1.5 GHz processor. The printer is controlled via Wi-Fi from the Fluidd or Mainsail web interface, sending G-code from any slicer (Cura, PrusaSlicer, OrcaSlicer). No proprietary software required; USB/Type-C connection allows offline control. The user has full access to macros and advanced Klipper tuning, without hardware modifications. |

Which one to choose
Choose Kobra 3 if…
you value max print speed, price and work area. «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.»
Choose Sidewinder X4 Pro S1 if…
it shows no measurable advantage over Kobra 3 on the available specs: consider it on price or availability.
