How to Fix Heated Bed Temperature Uniformity (Large Bed)
Step-by-step fix for heated bed temperature uniformity (large bed) on Bambu Lab printers including X1C, H2D, P1S, and A1.
How do I fix heated bed temperature uniformity (large bed)?
- 1
Pre-heat the bed 5 minutes before printing to allow full thermal equalization. Large beds (400mm) take longer to reach uniform temperature.
- 2
For parts near bed edges: add a 8–10mm brim and increase first-layer bed temp by 5°C. Edges cool faster than the center on large heated beds.
- 3
Consider printing centered on the bed rather than near edges for critical parts. The center 60% of the bed has the most uniform temperature.
Pro tip: Bed temperature uniformity affects first-layer adhesion. Center your parts for best results on large build plates.
