Also, French engineering has a habit of turning sound concepts into messy overengineerd but underbuilt results
Any example ?
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 🤔
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.
For records, this is the model in Freecad and how it is sliced in BambuStudio 
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
