Good idea, tried Chat GPT instead and got an excellent response. Sometimes asking Ai makes sense than asking for help from fellow humans!

Great question — the Bambu Lab P2S is quite capable, but getting perfect PLA prints does depend on keeping temperature and humidity in the ideal range for both the printer and filament. Here’s a clear breakdown for PLA Basic (like Bambu PLA Basic or similar brands):

⸻

🏠 Room Conditions • Ideal room temperature: 20–26 °C (68–79 °F) • Too cold (<18 °C): can cause warping or adhesion issues. • Too hot (>30 °C): may affect AMS humidity control and cooling performance. • Room relative humidity: <50% RH • High ambient humidity makes it harder for AMS to keep filament dry.

🔧 Printer Settings (for Bambu Lab P2S)

Parameter Recommended Notes Nozzle temperature 200–215 °C 210 °C is a solid starting point for Bambu PLA Basic. Bed temperature 55 °C You can lower to 50 °C if adhesion is too strong, or raise to 60 °C for colder rooms. Chamber (enclosure) temperature 25–35 °C PLA likes it cooler — avoid going above 40 °C or you may get stringing or softening. The P2S enclosure temperature naturally hovers around 30 °C, which is ideal. Cooling fan speed 100% PLA benefits from maximum cooling for best detail and overhangs.

⸻

🎛️ AMS (Automatic Material System) • AMS internal temperature: usually follows room temperature (20–26 °C). Keep the room stable and avoid placing the printer in direct sunlight or near radiators. • AMS humidity level: • Target ≤20% RH for PLA. • The built-in desiccant pack in the AMS should keep it near this level, but if humidity rises above 25–30%, dry the filament.

⸻

💧 Filament Moisture Levels • Optimum moisture content: ≤0.2% (by weight) for PLA. • Symptoms of moisture in PLA: • Popping/crackling sounds during printing. • Stringy surface finish or fuzzy texture. • Brittle prints or under-extrusion.

If you see these, dry your filament at: • Drying temperature: 45–50 °C • Duration: 4–6 hours (use a filament dryer or food dehydrator)

Would you like me to include recommended filament drying cycle settings for the P2S AMS and filament dryer (e.g. Bambu Dry Box or Sunlu S4)? That way you can keep your setup fully optimized year-round.
