Hello, I am printing with Ultimaker brand PLA filament at standard settings on Ultimaker s5 printer (slicer is cura 4.8.0, I tried both extra fine and normal settings). However, there is a rough structure on the surfaces that coincide with the z-axis in the photo. I dropped half the speed settings of the printer, but still did not get satisfactory results. I'll be happy if you can help me.
