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?
