Hi, I don’t understand why are these diagonal lines appearing on the top layer of the black filament, it feels smooth to the touch but they are visible, this is sunlu pla, I have the ironing settings on, using cura slicer, 3 walls, 6 top layers, 20% infill, how can I fix this, thanks
I think it might be slightly overextruding on the ironing, maybe try a lower flow percentage for the ironing.
Maybe the hilbert upper surface will produce something less visible than straight lines… to be tested on a small part of your model / reducing the height
