This came from my Bambu P1S, I did a hotend replacement a week ago and I only print simples models since. This time I tried to print a model a bit more complexe with supports and it failed. Filament is dry, ambiant humidity is 7% in the AMS.
Do you have any suggestions ? Thanks
Looking at your video, that's definitely a nozzle collision issue. Try enabling "Z hop when retracted" in your slicer settings (should be under travel options). This will make the nozzle lift slightly when moving between parts, preventing it from hitting your model. Also, for models with such a small footprint, consider adding a brim for better bed adhesion - looks like the impact is knocking it loose from the bed.
