| Software notes | 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. | The X-Plus 3 is natively supported by QIDI Print, the company's official slicer based on PrusaSlicer, which offers pre-configured and optimized profiles for supported materials, ensuring a ready-to-use experience. The software's user interface is designed to simplify the print preparation process, from support generation to advanced cooling configuration. Because the printer uses Klipper-based firmware, advanced users can interact directly via the integrated web interface (Fluidd or Mainsail), allowing for in-depth monitoring and fine-tuning of print parameters in real time. The system is also fully compatible with third-party software such as Ultimaker Cura, Simplify3D, standard PrusaSlicer, and OrcaSlicer, offering maximum flexibility in workflows. |
