Rough top layer ASA

[arverbo 0]

I'm printing with ASA filament on a UM S3. The top layer has a rough surface. 4 top layer lines, nozzle 0.4, layer height 0.2.

Tried ironing but then the surface looks really bad. I have had good results in the past. 

Which setting am I missing?

This is how it looks.

how is the infill? or support if the part is hollow on the other side.

 

It looks like there is not enough support below the top layer.

 

can you post perhaps the model or UFP file?

On this part the infill was 60%, zigzag.

I lowered the extruder flow and top surface flow by 5% and got a better result.

strange to me it really looks like a support issue, 

perhaps the bed adhesion failed on the print , but glad to read it's solved
