| 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. | The STM32 board runs Marlin and communicates via USB Type-C or TF card; it works with any standard slicer (Cura, PrusaSlicer, Simplify3D) without proprietary restrictions. Lack of Wi-Fi requires physical transfer of G-code files, but ensures full offline control. |

Which one to choose
Choose Kobra 3 V2 if…
you value max print speed and max bed temperature. «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 X3 Plus if…
you value maximum z height, work area and price. «The Z height determines how tall a part the machine can produce in one print. Vertical objects such as vases, load-bearing structures, or casting patterns require a high Z travel. A lower value does not affect quality but forces the user to split or reorient the model. Z height should be considered alongside the XY surface to assess total usable build volume.»
