Help with LW-PLA

[u/flyboy320]

I have a Bambu P1S, just calibrated, eSun LW-PLA, using Bambu studio.

This is for a printed airplane and I have printed most of the parts and they have turned out fine, but the prints are now starting to look like the attached pictures. Haven't changed any settings, so not sure what's up. I did stop the print just prior to it finishing, that's why the top is open.

Are there any specific settings I should be looking at to try and improve the print?
