| Software notes | It runs Kobra OS (based on Klipper) with a 4.3-inch touch interface. It is compatible with Anycubic Slicer for color management and connects via Wi-Fi for remote monitoring through the app. | 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. |
