Issue with top of domes

[lamiskin]

Hi,

I've been having a few issues with top of domes.

It looks like the very top layers are not solid and leave holes.

I've tried increasing the number of 'top' layers, but so far has seemed unsucessful.

Could the issue be the layers being to quick and the material not cooling enough before the next layer starts?

I've attached some images to show the issue.

I havent sliced a dome with 3.0 but most likely those arent top layers. Its perimeters. You would want to increase primeters to correct that. Also lower the layer height a bit and increase infill at the top of the dome.
