When I look closely during the print, I notice the filament also isn't "sticking" very well to the layer below during the print process. Will post settings shortly

EDIT:

Ender 3 Pro with BMG clone DD extruder and properly calibrated e-steps running Klipper and Prusaslicer

Polymaker PLA Pro, 0.4mm nozzle with hotend at 215 and bed at 60

Print speed is 85mm/s for perimeters, 20 for small perimeters, and 20 for gap fill

Retraction is 2mm at 45mm/s with retraction on layer change enabled

Hello all,

For some reason, I can consistently and near flawlessly print 60mmx60mm tuning towers with relatively mild bed adhesion issues, but steady printing after the first layer, but trying to print larger objects always ends with this strange wrinkling/breakage, and if I manage to finish the print, it has abhorrent layer adhesion issues. However, smaller objects seem to print very well. Notice how the beginning of my organic supports are very sturdy with no bed or layer adhesion issues.

I've already cleaned my glass bed with dish soap and water. I don't think having hard tap water would cause this. I've also already leveled my bed and set up a manual bed mesh. This has been happening even with my closer-to-stock metal bowden tube creality extruder. My consistency with tuning towers makes me think the issue is not related to pressure advance.

Printing on an otherwise stock 2018 Ender 3 Pro with a glass bed, silicone bed mounts, Trianglelab BMG clone, and Creality 4.2.7 board with Klipper.

Using Prusa slicer, Polymaker Polylite PLA pro, with 210c nozzle on all layers, and hotbed at 65c first layer and 60 afterward. Fan speed off for first 3 layers, then runs at 20% min and 100% max.

Printing speed is at 30mm for the first layer, with perimeters at 100mm and 3000sq mm accel. Retraction length is 5mm at 60mm/s with 40mm/s deretraction.
