I have an Ender 3 for two weeks now, my first 3D printer. I think I have a problem with top layers. See the left 3 stones on the first picture. It looks like lines and it feels like raised lines. The outer lines (walls) are perfectly flat, but the surface in between has heavily raised lines. I started with the standard Cura profile for the Ender 3 and tried .2 and .12 mm layer height, 2-5 top layers, 1 to 2 top surface skin layers and 5-20 % infill, all gave similar results. The only setting that solved it is the ironing feature (the fourth stone). While this solved it, it feels like I'm hiding an error in my printing with this feature and I would like it to print decently without ironing. The cat shows that my printer prints fine if no top surface is present. I have an Ender 3, upgraded with some fan guards and bowden clips and use Cura 4.5. SKR mini E3 and upgraded bowden tubes are on the way.
- Is this normal?
- What could be wrong?
- Is ironing a commonly used solution?
- Any idea what might fix it (apart from ironing)?
