90% of my S3D prints have holes on top layer

[Konky]

Moderate speed, 0.06 layer resolution on an UM2 which works kinda perfectly on Cura

I've attached the problem.
About every print I make has no proper tops.
I've the standard 2 shell layers but they simply do not properly work on top.

This model had infill (13%) which is normally more than enough, it should work with 0% infill as well.

Please give me some hints about the issue.

Material is ABS, temp is 240%, chamber is mostly enclosed, fans were low

Have you already read this: https://www.simplify3d.com/support/prin ... top-layers

It pretty much already lists every suggestion I would give

Hi,
I did read through but the pictured problem looks very different to mine.
I'll experiment more and use a lot more solid top layers than the 5 currently set up

i cant tell what you have there because we have no factory file posted but unless the top of the model is perfectly horizontal then you dont have any top layers. those are perimeters. looks like the top of the model is coming up to a smaller point, things are getting heat soaked and nothing will bridge because of it. unless you post a factory file anyone is just guessing.
