Software notes The printer works with Anycubic Slicer Next, derived from OrcaSlicer and optimized for the Anycubic ecosystem; it supports multi-plate management and object skipping during printing. Remote control and real-time monitoring are available through the Anycubic app (iOS and Android), connecting via LAN or cloud. The proprietary firmware is not currently open source; native Klipper compatibility is not supported. 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.
