| Software notes | The machine comes with the proprietary Qidi Print software, a slicer based on proven open-source architectures, specifically optimized for the profiles of the technical materials supported by the printer. Users can still generate G-code using other widely adopted third-party slicers on the market, such as Ultimaker Cura, PrusaSlicer, or Simplify3D, after manual configuration of machine and extruder parameters. Although it lacks native cloud features or advanced remote connectivity for corporate fleet management, it supports direct file transfer via local Wi-Fi or USB drives, ensuring a secure offline workflow for intellectual property protection. | The machine natively runs on Klipper firmware, offering comprehensive control and high computational speed for advanced features like input shaping. The user interface is managed locally via a large 5-inch touchscreen. Remote monitoring is facilitated by the integrated 1080p AI webcam with error detection for extrusion failures. For slicing, the manufacturer provides QIDI Studio, a software derived from PrusaSlicer/Bambu Studio, specifically optimized for high-temperature material profiles. Users can also access the Fluidd web interface for advanced control over the printer parameters and print offline via a USB drive or through the local network. |
