Hmmm. Looked good in preview mode

Perimeters/shells set to 6 6 and 6 as advised by thenpart designer.

Somewhere there is a %overlap so the infill goes further into the outline to help prevent this

Ah yes. What do you usually use for this?

The default 15%?

Depends on he geometry sometimes I'm up to 50% to ensure overlap.

Really?

See with the bigger pieces I print, S3D has done well....if there are no holes. Then I run into this issue

If I use Cura, I run into the grinding over the surface...requiring some z-hop....which should really just be part of what Cura does! I'm trying this very print on Cura and from upstairs, I can hear it grind away on the surface. Very aggravating! One slicer won't do holes right, one will but drags across the surface!

Here's what 0.40 nozzle and 30% Outline Overlap did

How many print hours have the coupler?

257
But here's the thing....only an issue on printing items with holes in S3D

Did the kitten print recently and it came out gorgeous!

I'm seeing what 50% does in the preview now

Post the FFF, it might be that cura uses a smaller nozzle simulation, that allows thinner lines (les possibilities of gaps, but slower and also extrudes less mm/2 so there's less material per/second and that helps to push the filament. Maybe you just need to raise the temp 5-7C?

I'm using the same as before, Frederick's...with the suggested changes you offered a bit ago (he has an extended so Z is 210, uncheck Coast at End, etc)

So here's what 50% Outline overlap looks like

I am starting to wonder if I have too many perimeters (The designer has top, bottom outline set to 6...since it's a structural pieces, he advised it for more strength)

Yeah....it's definitely the perimeters...if I take it down to 4 (from 6) I get this...

You could, like I said, change the nozzle width extrusion from default 0.4 to 0.35, alower print time, much less chances of gaps

I did that on the first time through, used 25% outline overlap and 0.35 nozzle (6 perimeter, 6 top, 6 bottom)
