I'm not sure if this is a bug or me not using the correct setting here, but i've been directed here from the 3d printing discord since we cant find an answer.
Essentially, any 1.2mm wall in my model gets sliced as 2 outer walls + one of the following:
- If "fill gaps between walls" is on, then i get the 1st picture where it I get a solid fill but made up of a load of diagonal lines Pic 1
- if "fill gaps between walls" if off, then i just get a gap the whole way up. Even the top layer. no top layer gets printed. Pic 2
It should just slice as 3 s
