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
@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
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.
