Software notes Equipped with Kobra OS, a Klipper-based firmware, controllable via a 4.3-inch touchscreen. Compatible with Anycubic Slicer and third-party software like OrcaSlicer. Features Wi-Fi for remote control via app. Multicolor printing requires the 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.
