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?
Make sure your nozzle is high enough too. Whereas PLA needs to be squished down against the build plate, PETG should 'lay' down from the nozzle. Or else it will stick to the nozzle instead of the previous layer. If you're manually leveling using the paper method, you would want to use something thicker like a note card instead of the usual sheet of paper.
