Please, has anyone had such a problem? I have been struggling with it for 3 weeks, I have the impression that it cannot be set.
I would like to print the model exactly as I designed.
Unfortunately, by setting the option "External Thin Wall Type" to "Perimeters only", the walls of the model become bold after printing. In my case, it is not acceptable, I designed the last layer with a thickness of 0.4 mm. I don't want a thicker one. Sometimes there are still holes in the last few layers.
And if I set option "External Thin Wall Type" to "Allow single extrusion walls", holes are formed in the walls.
I've already given up hope that this program can do it well.
I am enclosing a model, but many people have seen it and said it is not broken.
