I'm using Bambu Lab P1S printer with original Bambu filament PLA Basic. The first model is excellent! No issues at all. But the second one has a problem with inner hole... I tried to print several times, and I'm getting filament "spaghetti" inside the model. 1st attempt was with default settings and 100% print speed 2nd attempt - default settings and 50% speed 3rd attempt - 0.08mm Extra Fine BBL X1C profile, but it also doesn't help to solve this problem. Any suggestions? Thanks
