| 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. | 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. |
