Alright, trying another set of pictures here.

This is a recent print (I didn't have the fan running, which I assume is why we have the melty lines, but ignore that):

The most egregious problems are at the corners of the hexagons (the curved cutouts) and the big circle. Those are supposed to be flat, and as you can see from the picture, they are nowhere near that.

What I see in S3D is:

Now, I'm not looking for perfection here, but I have seen much better, smoother prints from this machine before. So it seems likely to be some obvious setting I'm missing in my S3D.
