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

        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 🤔

          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.

    Did you check preview mode on slicer? Do you use your own settings? Is purge line always that long?

      I use factory preset “0.2mm standard” for a 0.4mm hotend. The purge line looks normal to me. I had an other comment with bambustudio and freecad files.

        Looking again at your pic and wonder if part tilted while printing due to small area on bed. If it did, adding manual support to the print would help to stabilise as it goes up. Only thing is, that doesn’t explain why there is filament on the right of the picture.

    Have you tuned/dried the filament? As others suggested, you may want to add additional supports and slow the printing speed down.

    The print itself looks pretty mint, apart from the failure. If you don’t have hot end leakage around the screws this looks like a design / orientation placement error
