Software notes PrusaSlicer (optimized) and Prusa Connect for remote control. The machine accepts G-code from any slicer (Cura, Simplify3D) and communicates via USB, Ethernet or Wi-Fi using an open Marlin-based protocol. Compatible with OctoPrint and offline management. Does not require a Prusa account to print, unlike machines with proprietary firmware that block features without connection. 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.
