  @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 🤔

      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.

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

  I might be seeing it wrong, hard to tell from just this perspective, but could it be placed so the entire side, or entire back, is making contact with the bed? Increasing your contact surface can help dramatically as I said in my other reply.
