Software notes Powered by Anycubic Kobra OS (based on Klipper) and operated via a 4.3-inch capacitive touch interface. Compatible with Anycubic Slicer, OrcaSlicer, and other third-party software. It offers Wi-Fi connectivity and integration with the Anycubic app for remote monitoring. Multicolor printing requires the external ACE Pro module, sold separately. 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.

The differences that matter

  • Price: Kobra 3 V2 349 € vs Original Prusa MK4S 999 € — Kobra 3 V2 wins (+186%)
  • Native Klipper: Kobra 3 V2 yes, Original Prusa MK4S no
  • Work area: Kobra 3 V2 255×255 mm vs Original Prusa MK4S 250×210 mm — Kobra 3 V2 wins (+24%)

Which one to choose

Choose Kobra 3 V2 if…

you value price, native klipper and work area. «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.»
