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
It needs more support sooner in the print. While it’s not a bed slinger, extrusion still puts torque on the print. Both from the pressure down of the plastic squishing ontop of the lower layers, and from the nozzle pulling along as it prints.
I’m actually surprised the print even made it that far. A model moving even a tiny bit can produce a lot more than just some wobblyness in the surface finish. I’ve had plenty of prints that basically just fall apart and become spaghetti without the models even detaching from the bed.
Have you tuned/dried the filament? As others suggested, you may want to add additional supports and slow the printing speed down.
