| Software notes | Full Klipper firmware with integrated Mainsail or Fluidd web interface via Wi-Fi. Compatible with any slicer that generates standard G-code: Ultimaker Cura, PrusaSlicer, OrcaSlicer. The protocol is open Klipper, the user can directly adjust Input Shaping and Pressure Advance from the web interface without additional software. | 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. |
