Not sure if the proper word is "wavy" or "ripples" etc for what I'm seeing. 2 of my printers just started doing this, and I've tried to go through the printers, clean, tighten, lube, change nozzles etc. But they seem to have this "wavy" effect to the prints, as before it was smooth, any ideas? CR6-SE

I've printed fine on my CR-6 SE, and this time I notice the filament not really sticking together. I auto leveled the bed, even cleaned the bed and put some stick glue down but it does this in the photo, any suggestions?
I have swapped nozzles to a new one, same issue.
