I’s like if someone can tell me what is happening in these pictures. A little background X1C obviously PLA 4 things printed 2 the same 2 different 3 were given a brim and it happens that those 3 are the ones with the issue’s. This also happened with one of my first prints I was using PLA+CF the side facing up was perfect but underneath there was a gully that ran the length of the print(suppose to be there) but the roof of it looked like spaghetti similar to these now any help would be gratefully accepted.

Thanks, Brenden

You can’t extrude plastic over open space and expect it to only go where you want it to go. You need to add supports to those underside/overhang areas or they will be messy.
