I am getting this kind of error every time i print, on the edges of all my prints, it does not complete them, even the one that i marked as good, is not actually good and is not flat enough to connecting to the other half, can anyone help me on how to fix it? do i need to make the print slower? or increase the infill? the density any suggestion? so i can stop wasting PLA, thanks and I am using this printer
