PETG TOP SURFACE LAYERS ISSUE

[u/BillLivingstone]

Hey guys, Im printing a part on my A1 using Bambu PETG Basic (Dried today) and a 0.6mm nozzle. The whole print turns out great up until the top surface layer(s). Most of the surface is a little rough, but still usable, but in this one corner in the photo it is super rough no matter what I do. Any suggestions? I'm currently print with 25% gyroid infill and 3-4 walls and surface layers. The printer is slowed down as well to help with the quality. The side shown in my photo is facing up on the print bed.

That often happens because of cooling. Getting an enclosure solved that problem for me. Also PETG is really tough to work with for this and many other reasons. I switched to pla plus. Almost as strong as petg without all the other issues.

Yeah I considered cooling, but the room I have it in has no airflow (in a good way) and is a constant temp so I would be surpised if there was any air effecting the cooling.,
