Hi,
Been printing with my new Ender 3 Pro for a few weeks now and all of a sudden the nice clean top layers are not so clean anymore. I tried making one before this and it was a lot worse so I changed to Creality white PLA (was using black). I thought perhaps over extruding so I double checked the E-Steps and it was slightly over extruding so I adjusted it an tried again changing to Creality white and got this. This one is better than the first one I made but not like other items I've printed in the past couple days. I don't believe I changed anything profile setting in the last few days. I was running a Dr Vax bed leveling STL today and ran it three times to make minor screw adjustments to the bed. I saw this pattern starting to show up while running it the Dr Vax STL, but not to this degree. Would this be referred to as 'scaring' or something else?

Using Cura 4.10.0 slicer. .4 nozzle. .2 layer height. Print speed 50mm. Creality PLA (200c extruder / 60c bed). Retraction enabled - 6MM (I think that is Cura default). Combing Mode - Not in Skin (default distance with no retraction is 30mm - Cura default).
So what happened and ideas on what to try to fix??
