Uneven top layer

Hello guys, i noticed my latest prints have uneven top layers as shown in the picture. I have this problem with generic PETG and prusament PLA, both look the same. Can you guide me how to solve this problem? thank you

Hi Matus,

you control the bottom layer fill quality by raising or lowering live Z, in preference to adjusting Flow. 

adjusting flow to sort your first layer, can cause problems further up the model!

First layer is ok.  Try increasting the number layers on the parameter.

I think what @cwbullet is trying to say is to increase the number of top layers in the Layers and perimeters section of the print profiles dialog. That was my thought too. What infill pattern/percentage are you using?

solved

thank you all for your input. for info - 20% grid infill, 4 bottom layers, 5 top layers, layer height 0,2mm. What helped was to set extrusion width for top infill layer from 0,4mm to 0,3mm. top layer is now super smooth 😀 not sure if it is the best way, but for now, it works...
