Top layer quality

[BeerMedic522]

I’ve tuned according to Ellis. How do I improve my top layer quality?? It doesn’t matter what filament I use, this is ASA…

At first glance, it seems like there is just a bit too much plastic being extruded. I would try reducing flow multiplier by 4-5%

As above, also just re-look at your Z-Offset - it looks a bit too close

That looks overextruded to me. I'd check that again, and look at the top layer settings on your slicer.

Sorry all of this is new, what top layer settings should I change?

What slicer are you using?

[Simon2.4]

in SuperSlicer:

how did the first layers look? if you had a similar pattern on the bottom fills, I would suggest reducing the extruder flow for the entire print.

ehmm, from my understanding, that would only show on the bottom layers?

I meant, while it's printing, do the first filled layers have the same bumpy ridges as you top filled layer.

No, first layer looks good. 
I’m using Prusa Slicer.

not sure if the top layer flow adjstement is unique to superslicer but a workaround I read about is to manually insert a gcode command to modify the extruder flow just before the last layer. Also, you may want to gave SuperSlicer a try. it's based on Prusa Slicer so it should be easy for you.

Look in Print Settings/Advanced. Make sure the Top solid infill isn't too wide.

I tried SS but it hadn’t updated in forever. I’ll have another look…

yah that may be an issue.

Sorry, late to the party, but I would recommend tuning your Extrusion Multiplier: https://ellis3dp.com/Print-Tuning-Guide/articles/extrusion_multiplier.html

Nope.

That bottom layer pic looks like Z is too high. Try adjusting and print it again, if you can.

But it also seems like, from the top layer pic only, like over extrusion.

ASA: I have knocked down to 95% EM with better success. But some is more buttery than others and needs less EM.
