| Software notes | The machine relies on an architecture based on Klipper firmware, which provides advanced computational performance and native features like input shaping to reduce vibrations during high-speed movements. Users can interface via the integrated 5-inch touchscreen or through the standard Klipper web interface. The recommended official slicing software is QIDI Studio, a program derived from PrusaSlicer and Orca Slicer, optimized to leverage the machine's profiles and proprietary print parameters. However, the system maintains an open approach and is fully compatible with third-party slicers such as Orca Slicer, PrusaSlicer, and Cura, ensuring maximum flexibility in the daily workflow. | 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. |
