| 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. | The QIDI X-Smart 3 is primarily managed via QIDI Slicer, a proprietary software based on the latest versions of PrusaSlicer, optimized to fully leverage the machine's high speeds and CoreXY structure. The interface offers both a beginner mode and an advanced mode for granular control of parameters. The printer comes with pre-installed Klipper firmware, allowing advanced users direct access to the Fluidd web interface for real-time monitoring, calibration, and macro customization. Nevertheless, compatibility is guaranteed with the most popular third-party slicing software, including Ultimaker Cura, Simplify3D, and standard PrusaSlicer, ensuring a flexible and adaptable workflow. |
