Hey, I am new to the cura ultimaker slicer, but i'd like to know how i could fix wrongly generated helper lines. Couldn't find anything about it, but here's the problem: After slicing the program generated a helper line that interferes with the model. I don't like the top and bottom layer pattern either, but that's not relly relevant. Any idea how to fix this? Cura version 4.8.
