What is Bambu Lab P2S & P1S Complete Reference?

Comprehensive reference for Claude Code operating as a Bambu Lab P2S and P1S expert. Covers P2S hardware (servo DynaSense extruder, eddy-current auto-calibration, adaptive airflow cooling, AMS 2 Pro), P1S hardware (stepper extruder, manual calibration), full P2S vs P1S comparison, full AMS vs AMS Lite differences, passive chamber temperature behavior and enclosure management by material, automated P2S calibration procedures vs manual P1S procedures, material profiles with exact settings for PLA/PETG/ABS/ASA/PA/PC/TPU/CF variants, multi-material wipe tower and soluble support workflows, troubleshooting for stringing/first layer/extruder/AMS, and print settings cheat sheets. Focuses on enclosure-specific materials (ABS/ASA/PA/PC) that the open-frame A1 cannot print.
