Repetitive banding issue (lemmy.world)

Hey all, so this is the biggest thing I've tried to print. I'm using PETG. I'm getting a lot of repetitive bands of underextrusion that seem to stack up and get worse as the print progresses.

What do you think is causing this? Is this just an inherent thing in the way an Ender 3 works by moving the bed?

The typical guesses in a case like this:

Bed leveling
Crappy extruder that needs to be tightened or better replaced (I can really recommend the TBG Lite, amazing extruder)
Temperature too low
Crappy or wet filament (wet doesn't apply to PLA, but PETG prints super bad when wet)

Or all of the above.
