gaps in top layer

[Electricfuse 0]

 

Anyone know what causes there to be gaps in the top of prints?

Probably insufficient infill just under this?  Not certain.  Could also be minor underextrusion but I don't see any other underextrusion.

Ok, I had 10% infill, but print called for 0. But that sounds right will try again

That's a great recipe for a print to fail. Or get destroyed if you accidentally knock it over.

 

Could also be worth considering the infill pattern: if you don't particularly need strength, zigzag is a great infill pattern to use to in this sort of case because (along with grid, but printing zigzag is better because it requires fewer retractions) it has the infill lines closest together, meaning the top is supported much better.

 I think 20-25% should be (hopefully) enough for this area.  Also you want a few "top skin" layers.  At least 3 layers in the top skin.
