Need some help. Found some issues with 3d prints. All of a sudden lines are coming on the side walls in both X and Y axis.
Is it due to Mechanical issues or slicer?
I am using Simplyfy3d with Marlin. Machine custom made 300x300 open type Prusa style.
I tried to adjust the Z lead screw, applied some machine oil, tighten the screws, checked for belt tension etc.
