Hi, does anyone know how to get rid of these two bands of extra material around the holes?
Have you tried printing it yet. Those look like they just may be representations of different filament lay downs that won’t impact your print.
You can verify this by unchecking the sliced boxes and try to identify which layer line type it is. By checking and unchecking the boxes, you’ll be able to diagnose what that actual line’s function is. From there it will be easier to diagnose what’s going on. I’m willing to wager that you have some internal structure in the model that the slicer is trying to accommodate. Pull the slider further down to reveal these interior structures if they exist.
The print was impacted by this. I have found the setting which caused it however, I had X-Y Compensation from trying to dial in XYZ Cubes, and once I set that back to 0, the band went away in the slicer and in the print.
