Software notes Compatible with the main slicers on the market. It supports cloud connectivity via the Anycubic app and Wi-Fi for remote monitoring, while still allowing offline use via USB. Compatible with PrusaSlicer (open source, with material profiles verified and maintained by Prusa Research), OrcaSlicer, and SuperSlicer, as well as any slicer that exports standard G-code. The firmware is based on Prusa Research's open-source Marlin fork, with input shaping support. Unlike Bambu Lab models, which use a partially proprietary protocol and work best with Bambu Studio, the CORE One L accepts generic G-code via USB, SD card, and PrusaConnect. The user is not locked into a single software ecosystem and can freely modify or update the firmware.
