Software notes The firmware runs on a proprietary Kobra OS layer built on top of Klipper; the official slicer is Anycubic Slicer Next, derived from OrcaSlicer, available for Windows and macOS. Third-party OrcaSlicer is also supported. Remote monitoring and control are available via the Anycubic app (iOS/Android) over LAN, with no mandatory cloud connection required for ordinary printing operations. Unlike the Combo version, the ACE 2 Pro module is not included in the box. The primary software is Snapmaker Orca, an optimized version of the popular OrcaSlicer, which provides native management of the four toolheads and factory-calibrated material profiles. The printer can also be seamlessly managed via the Snapmaker mobile app for remote monitoring, taking advantage of the built-in 1080p camera. The internal firmware is built on Klipper, Moonraker, and Fluidd, which Snapmaker has made open-source, allowing experienced users to customize the machine and integrate it into complex workflows.
