Software notes The printer runs Marlin firmware with an open G-code protocol, compatible with any slicer like Cura, PrusaSlicer, or Simplify3D. Artillery Slicer is a customized version of Cura with optimized profiles. WiFi connectivity allows file transfer via a dedicated app but doesn't support a full web interface. Input shaping and pressure advance are preconfigured and factory-tuned, reducing initial calibration. 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.
