Ultimaker Cura is for some reason leaving gaps in the outermost layer of the perimeter walls, only on some parts. They are diagonal in a way, much like my other problem of diagonal stringing, which is obviously made by Cura and not overheating/overextruding because it is not straight dripping lines but little diagonal lines moved consistantly throughout layers. I don't have pictures right now, but I hope you can imagine. You cannot see this in the files, but it is very obvious in the prints and its pretty annoying. Anyone know any ways of fixing this? Like a setting or (I know I shouldn't say this on this site but) switch to a different software? Would love some help.
