| 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. | Full Klipper firmware with integrated Mainsail or Fluidd web interface via Wi-Fi. Compatible with any slicer that generates standard G-code: Ultimaker Cura, PrusaSlicer, OrcaSlicer. The protocol is open Klipper, the user can directly adjust Input Shaping and Pressure Advance from the web interface without additional software. |

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 if…
it shows no measurable advantage over Kobra 3 on the available specs: consider it on price or availability.
