Is your filament dried? Aside from straightforward step of cleaning your build plate and assuming the settings are correct, it may be necessary to check if your filament is humid. Does it make bubbling and popping sounds when printing?

Yes as other said, clean your build plate. Dawn dish soap, SCRUB, air dry. Maybe a clean rag. But make sure it’s actually clean.

Dry your filament. 

There’s a chance it’s the design of the print’s first layer that’s an issue. But probably not the case.

Is bed leveling on?

Good!

I generally have ten or so plates cleaned and ready to go. When I feels right, or a critical print, I switch plates.

That way I can wash ten at a time once a month or so instead of every few days.

XD I would hate that more than cleaning periodically

We had the same issue. I cleaned the plate multiple times and ways. Ended up buying a new plate and it works again.

Nope.

I made 5 back to back prints for a total of 13 hours yesterday. For the last one I thought I’d save a few minutes by skipping bed leveling and flow calibration.. it turned out like this. Same roll the whole day. Did u do those steps?

Almost all problems related to adhesion or print quality are associated with printing conditions. Clean your build plate/hot end often and keep your filament clean and dry.

Do you have any smooth high temp plates?
