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

For records, this is the model in Freecad and how it is sliced in BambuStudio

@gdaofb27584 According to object rotation I don't think it's printing issue, but nozzle hit the model and rotated it

You are right ! I did a second try, with a different preset "0.08 High Quality". It also failed.

The timelaps show the hotend hitting the model base. ( see this streamable ) It's the first time it happens, I don't know what to do to fix it 🤔

@gdaofb27584 The base need few supports, it's not stable enough
