Re: 1mm vertical surfaces too thick.

I think it's a bug, see my post above.

Re: 1mm vertical surfaces too thick.

The ultimate answer is to design in multiples of .48
I have been doing design that way for years now.  Yes, once you get over a few mm in thickness it will be less important.  But on the small stuff it can really help.

Re: 1mm vertical surfaces too thick.

So, just to see how it would come out, I grabbed the latest version of Cura and tried to use it for the 1mm-sided rectangle test. I left the layer thickness at .2, flow % at 90, infill at 50% and the perimeter width I set to .4 (it requires it to be a multiple of the nozzle size, so I figure this would be the best way to tell it to do one perimeter).

For starters, it really tried hard to do infill, doing a back and forth pattern across the 1mm walls. This resulted in a horrible looking print with gobs of plastic all over the sides. It was not nice and smooth like what I get with slic3r. Much to my amazement though, the walls are *much* closer to 1mm! I get measurements from .97-1.12 but it's hard to find good spots because of the horrible gobs of plastic all over it.  Where I can find good spots, they are all right at 1.00mm

Unfortunately, even with the multiple of .48, it tries to do infill unless I tell it to do 0 infill. But that would mess up the other parts of the model that actually needs infill.

Yeah, I'm guessing it may be easier to roll back a few versions of Slic3r.  Try 1.0.0RC3. That is still my favorite version.  It simply does what you'd expect.  If you do that note that infill is stated as a number between 0-1 instead of a percentage.
