| Software notes | The H2S uses Bambu Studio as its primary slicer, with full support for proprietary features including automatic calibration, AI monitoring, and AMS management. It also accepts G-code exported from OrcaSlicer, PrusaSlicer, and Cura, though some advanced functions may not be available with third-party slicers. Laser and cutting functions are managed exclusively through Bambu Suite. Developer Mode is available, exposing MQTT access for custom integrations. | 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. |
