Hi all,Im having a few issues with my 3D printer at the moment which im think is a software or G-Code issue, i have these new strange ridges in my 3D prints.I installed a 2nd Z Axis rod recently as i thought this might solves the issues, however this has not done anything to change the problem.Has anyone got any idea, im thinking now it could be some issue in the G-Cofe for the Ender 3-MAXPicture as below if anyone has any ideas?
