Dec 1, 2025December 2025 focused on stabilizing calibration workflows, strengthening filament safety constraints, and enhancing device status UX across BambuStudio. Key outcomes include a more reliable calibration process with automatic nozzle-offset defaults, a refined calibration wizard UI, robust parsing and localization improvements, and expanded nozzle flow/type handling. Filament compatibility enhancements add safety constraints and a blacklist for TPU High Flow, reducing material misuse. Printer operation and device status features gain AMS cold-pull status checks, removal of the nozzle_mapping field for printers without a nozzle rack, and a stop-filament-change option for improved operational control. Additional bug fixes in calibration parsing and localization further improve reliability. Overall, these efforts reduce setup friction, prevent unsafe material configurations, and empower operators with clearer status and control while showcasing strong UI/UX, parsing, and safety engineering skills.
