| Software notes | Native Klipper firmware with a 64-bit ARM 1.5 GHz processor. The printer is controlled via Wi-Fi from the Fluidd or Mainsail web interface, sending G-code from any slicer (Cura, PrusaSlicer, OrcaSlicer). No proprietary software required; USB/Type-C connection allows offline control. The user has full access to macros and advanced Klipper tuning, without hardware modifications. | 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. |
