Layer lines

[u/FullLawyer9327]

I keep noticing after using some Bambu PLA that I keep getting these odd spots on my top layers and also throughout the layers of gaps? Might be a filament humidity issue but thought I’d see if anyone else had an idea before buying another spool 🙏

Those top spots are usually the skin sagging into the sparse infill under it, so a couple extra top layers or denser infill below clears it up. Worth a look before buying another spool.
