Thank you for your reply Tim. The test part is 3 layers thick. When I got home I adjusted the extrusion multiplier from 1 to .9 (picture 1). The problem was a little worse so I went to 1.1 (picture 2) and it really improved the pin holes. I might have some slight adjusting left to do (had a little more stringing than usual), but your advice really helped. Thank you again for your prompt reply!

You didn't say how many layers are involved. But initial thoughts are a slight under extrusion - filament multiplier could be set a tad higher. You might try reducing elephant foot comp, not sure how that will affect gap fill, but is one of the levers available. The others are retraction settings...

Hello,

I am attempting to print a lightbox for a birthday gift. Before printing the entire thing, I wanted to print a test part to ensure everything printed properly. Upon inspecting the test part I noticed these pin holes in the attached (picture 1). I also noticed that there is another section that does not look like it extruded properly (picture 3). While I am not new to 3D printing, I am new to PrusaSlicer and the CORE One. I am using VOXEL PLA, standard .04 nozzle, and the factory .20mm structural print setting. My filament has been dried, and is stored in a cereal dry box with desiccant. The hygrometers both read 20% humidity. The lightbox was designed in Fusion and put a .2 mm fillet on all applicable corners. I printed two test parts (one with door closed, one with door open) with identical results. Does anyone have any advice on how to remedy these issues? Thank you in advance!
