Hey this is my first post here about any 3D printing so stick with me. I currently have an Anet A8 and in the beginning it all printed fine and almost perfectly but now the prints are constantly leaning forward and messing up. I have made sure that all of the little grub screws holding the pulley on the y-motor are tight and the belt is all tight. I have also made sure the screws holding the pulley on the x-motors and the belt were tight. I have recently updated the firmware on the printer and nothing changed. Is there anything I could be missing?
