Model itself prints in good quality except for the circle holes.
As you can see on the picture, the upper layers of the hole are printed fine, but the bottom is messy and strings.
This is after cutting some of the mess. The surface is otherwise alright-ish, but I really wonder what causes the first layers of the hole to be so messy.
Print settings are standard 0.16 layer height 0.6 nozzle Bambu PETG-CF defaults. Filament is dry.
it’s an overhang.. have you enabled supports? if you use a different material as interface layer you can get even cleaner
There’s a grid support everywhere, yes. 0,2mm interface spacing.
Yeah the inner opening outer wall didn’t stick to the support so it gets messy. Use pla on the interface layer and have 0 distance and you should be able to print it much cleaner
PETG, at least in my experience, can do that in small circles/ovals if too fast even with supports, so consider the speed in which those lines are laid down if the above suggestions dont help.
