Holes in the top layers

[latreides]

I am getting some gaps in the top of a couple particular prints (always at the exact same spots) and I am wondering what the best way to solve this would be.



Under extrusion is the first thing that comes to mind (or maybe recovering from a retraction?) but this is not a problem with any other print I have, and I have printed several test prints to check my extrusion multiplier.

I am printing with 4 top layers, and a 20% infill.

Look at the preview and check those areas to see if it shows it will print it.

My guess is that the area is to small a distance for the infill setting. Check it out on the infill tab and see if that helps at all.

Examining the preview closely shows that the spots where the holes show up coincide with the very center of an infill gap. I am going to try to increase the infill for the last 20% or so of the print and see if that solves my issue.
