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. Natively compatible with PrusaSlicer (based on Slic3r, open-source), but it works with any slicer able to generate Marlin-flavored G-code, such as Cura, ideaMaker or Simplify3D. The firmware is a Prusa-modified Marlin 2, fully open: no lock-in to proprietary software or protocols. The user has full control over the machine, but PrusaSlicer is recommended for optimal performance, as it includes exclusive profiles and features like dynamic flow calibration.

Which one to choose

Choose Kobra 3 V2 if…

you value price, maximum colors and native klipper. «The maximum number of colors indicates how many distinct color zones or materials can be used in one print without manual intervention. Two colors cover most practical uses, including soluble support. Higher values are useful for complex decorative models or color-coded prototypes. Each additional color increases print time due to transition purges, so the practical benefit should be weighed against the added time cost.»

Choose CORE One+ if…

you value closed chamber and max bed temperature. «A closed chamber reduces thermal gradients around the part being built, limiting warping and cracking caused by rapid cooling in high-shrinkage materials such as ABS, ASA, and PC. It also shields the mechanism from drafts and airborne particles. A closed chamber is effectively necessary for technical materials; for PLA and PETG it is an advantage, not a requirement.»
