Software notes 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. It comes with the proprietary Snapmaker Luban software, a free, unified application available for Windows, macOS, and Linux. Luban is tailored to fully utilize the independent dual extruders (IDEX), integrating ready-to-use profiles for various print modes (Copy, Mirror, Backup). Compatibility with major third-party slicers, such as Cura or PrusaSlicer, is also ensured via standard G-code export. Direct machine control is facilitated by the integrated Android-based touchscreen display and Wi-Fi connectivity for remote management.
