Description of the bug

The attached file seems to contain a layer of 0.049mm. I have contacted the Lychee team and when they open the attached file with UVTools, they do not see this issue.

I can reproduce it with UVTools 5.1.1 on Linux and 5.1.2 on Windows.

Because of the 0.049mm layer, UVTools sets PerLayerOverride to True which breaks my prints on my Anycubic M5s.

How to reproduce

  1. open attached file.
  2. see layers at height 1030 or so. There is one layer 0.049mm
