PETG warp solved

Running a .8 nozzle. Printing pieces that are covering 85% or more of the build plate and Z axis. Tried 5-6 different brands of filament with Creality Print preset. Always the same, bottom corners warp away from build plate.

Tons of experimenting later I found: Nozzle temp 240, bed temp at 80, model fan at 35% after 3rd layer, outer brim, 3 bottom & top layers, 4 wall loops, 15% lightning. DeepLee PETG Pro so far works the best and is reasonably priced on Amazon. (I am not affiliated with or compensated by DeepLee or Amazon. I am a user looking for what works cheap.)

No more warping. Only issue is last layer on top can and does get a little lip on 1 or 2 sides. A once around with a demurring tool fixes.
