Hi,
I've just swapped to a new PLA (Sunlu wood filled) and I'm getting strange lines in my top layer.
It is like some areas are just not being extruded at all.
Any ideas how I go about finding the cause of this?

The rest of the print is perfectly fine but the top layer is having issues? I would check the settings that effect only the top or top / bottom layers.
You said it's a new filament, is it a new profile for the new filament as well or have you successfully printed other filaments with the exact same settings?
Its a slight tweak of the profile I use with other sunlu pla filament.
I've tried to top layer setting tweaking bit not luck so far
Have you verified it's not a model issue? Also, is it on all top / surface layers, or only the final layers? Like if you printed a solid staircase, would each step have the surface messed up or just the top one?
