The title pretty much says it all. I was printing bed level test prints in PLA without any issue. After the fourth print, I tightened the front right wheel slightly and ran another bed mesh. Then I started seeing this. No print settings or filament was changed. I tried adjusting the z-axis offset but it had no effect. Has anyone else seen this and is there a solution? Thanks.
Check the hotend mounting or eccentric nut and not loosen/wobbling.
