Software notes The machine is compatible with major slicing software on the market. The manufacturer recommends using Elegoo Slicer, specifically optimized to leverage the CoreXY kinematics, multi-color printing via the CANVAS system, and vibration compensation algorithms (Input Shaping). Alternatively, popular slicers like Orca Slicer and Cura can be used, offering broad flexibility to users who prefer established workflows. The integrated dual-band Wi-Fi connectivity allows direct transfer of G-code files to the 8 GB internal memory without physical cards, while the internal camera enables remote monitoring and time-lapse video recording, simplifying the management of the printing process even from a distance. 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.
