Regarding the Outer Wall Inset - are you having dimensional problems? If you aren't then just leave it at "0".
Gaps in the preview can be caused by Coasting as the preview only shows moves with extrusion and the coast distance doesn't have any extrusion.
What looks like gaps but is actually white is probably the Z seam. My old laptop doesn't support the high end graphics and so mine never shows that. Round features can't hide the Z seam.
I got my dimensions nailed down now. However, to print very precise objects I had to tune the horizontal expansion settings to get them just right. Also, the gap the slicer was displaying doesn't seem happen in real life and the parts are printing very nicely.
Thank you for your help and have a merry Christmas!

Thank you for your help, I never would have noticed the inset, I set it to that for my 0.6mm nozzle but forgot to lower it accordingly. What would you suggest I set it to for 0.4mm nozzle, 0.2?
Oh and if you could, is there a way to remove these gaps between the hole inner wall and bigger hole outer wall? Only certain parts like to do that and I haven't found a way around it.

The Lego Beam Test 3mf file has an Outer Wall Inset of 0.3. I think that coupled with the .3 line width is what is hiding the outer wall. You can see a little bit of outer wall in the gear but essentially, the outer wall is there but it's line-to-line with the outermost inner wall. I hope that makes sense.
One of the Ultimaker Engineering profiles uses a .35 line width and a .4 nozzle. I seem to recall that is for higher accuracy. If I need to go smaller than .35 then I move to a smaller nozzle. There is a point where the flow through the nozzle falls off to "not enough" and affects the prints whether we can see it in the preview or not.
I've tried to show the effect of the Outer Wall Inset here in your last image. You can see that the outer + inner is about equal to one of the skin extrusions.

With that model loaded and set up for a slice use the "File | Save Project" command and post the 3mf file here.
Something is going on at the root of the gear teeth at what looks to be the 9:00 position also.
Hey Greg, I accidentally discovered what the cause was but I'm not sure why.
When I switched from line width 0.3 back to 0.4 like my nozzle it fixed it. It's a bit odd it would do that considering its ok to slightly lower line width by 60% on occasion right?

Oh, and the Gear at the 9:00 position has a "cutout" due to a Tinkercad glitch in the gear generator. I've never been able to get it to make a perfect circle in the gear core but once printed there are no imbalance or shape issues.

Here's another model with the same issue

I'm having an issue that Cura will not properly show outer walls. Let me know what you can, Thanks.

In support settings what is your "Support Z Distance" or "Support XY Distance" set to?
I use a 0.6mm nozzle and have both settings at 0.3mm or the same as the layer height, for a 0.4mm nozzle I'd set it to 0.2 as well as the layer height within 15% to 80% of the size of nozzle.
Some things that may help.
Might try a raft but I doubt it would change it much.
Have the base of the print be taller by changing the model if you made it.
Change the Z and XY Distance like I mentioned.
Try lowering the layer height of the print a little.
If nothing changes to make it print decently nice, lower the outer wall speed to 15mm/s and inner to 20mm/s and top/bottom to 15 or 20mm/s, additionally raise cooling power and lower temp a little if possible.

Cura 4.11.0/4.10.0 and Achane engine beta just started filling Cutouts/holes in randomly.
I don't think I've changed anything that could have caused this and I've successfully printed this part before with no issues. I have tried messing with the "fill gaps between walls" settings with no change.

I made a test model that has a few different wall widths to see how it reacts. What it seems like is Cura just doesn't like 2mm walls being hollow which is fine and ill fix it by changing to 3mm walls. Thanks for all the help and your time!

Ill try to simplify whats happening, I'm kind of lost in what I'm doing and this lol.
Issue.
I want a thin wall that's big enough to need infill instead of being solid, whats happening is its either filling it in entirely with what appears to be Top/Bottom and mixing that with infill, even when infill is set low. Fix, Set "Fill Gaps Between Walls" to Nowhere.
Second issue, Nowhere causes Gaps making for ugly prints, and on only some models there will be no roof in certain spots only. Sorry for the confusion and thanks for taking your time to help me!
-
Sorry about that, also I'm using Cura 4.11 and I've tried going back to 4.10 and its doing it too and I've never seen that until 4.11, and I used the stock Cura settings and its doing it in both versions too.
-
Hey, thank you so much for your help. However picture 3 and 4 are done with it set to nowhere and then have no roof at all.

These are my Profile and the STL for the model pictured.
Picture 1 and 2 are a different model but with a glitch occurring, model 3 and 4 are another model with different settings and a similar glitch happening by only changing "Fill gaps between walls" to nowhere or anywhere.
Picture 2 is only there to show an example of the top of the print and the Top/bottom settings
-
The third and fourth picture down are using different settings but are still not right (defaulted back to when it was working but no luck)
-
I've been trying to figure this out. after I updated to Cura 4.11 I set my infill to anything (currently 20%) and I get solid walls and the color code tells me its the top/bottom filling in the whole wall, It's not doing it to actual tops and bottoms just walls.
I've tried using stock settings and going back to old versions and it's still doing it, I know its a bug because its mixing the infill and top/bottom in a way where it might hit the nozzle on it.
The only thing that fixes it but would lower my overall quality would be to set wall fill gaps to nowhere instead of everywhere, but that would leave gaps.
Can't Print Temp Tower
in UltiMaker Cura
Posted · Edited by Reddley
I'm trying to print a temp tower but it acts like the walls are too thin to print without "Print thin walls" setting enabled. "Horizontal Expansion" is at 0 and it doesn't make any difference to lower the line width either. Please let me know what setting could cause this, Thanks.
Found the issue, it was outer wall inset.
