Does anyone ever use the 0.39mm layer height option, if so, do you have a photo you can share of a print at that resolution? I am thinking of using it for a fixture I have designed, but would like to know what it looks like before I commit

I tried it once to print an extruded profile, but it completely messed up. I will never use it again.

I don’t have a picture. I use this setting for test-prints. It’s acceptable for fast prints with straight (horizontal/vertical) shapes. When you print curved shapes it’s very ruff but in some designs this can be a ‘feature’.

I think it looks pretty decent
