Software notes The operating system is based on the open-source Marlin firmware, ensuring broad compatibility and stability for the user. The printer is supported by major slicing software on the market, such as Ultimaker Cura and PrusaSlicer, for which official preset profiles or easily configurable community profiles exist. Operational management is handled via a practical removable capacitive touchscreen, featuring a simple interface for manual control and monitoring. The machine operates entirely offline, reading G-code files via a MicroSD card or direct USB cable connection, without any dependency on cloud services or wireless networks. 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.
