Need some help with top layer concentric infill

[larryl]

Hi, I am using concentric infill and my top layer has small gaps in it, is there any way to fill these in better? Thanks in advance!

It may be better to use enough perimeters that these fill in the shape completely. You can then go to the Advanced Tab of the Process Settings and Allow Single Extrusion Fill for the Internal Thin Wall Type option. This will use a variable width path to fill in that very middle section for you. Let me know how that works and if you have any issues please post a Factory File so we can help further!
