I’m hoping you guys can help me figure this out. I have an ender 3 pro, running on marlin firmware. Every time I try to print something one of the corners will lift up like that and ruin the entire print. I installed a crtouch to help with leveling, installed upgraded metal bed wheels to help it not fall out of level. Even tried a glass bed with glue and it still does the same thing. I used a filament dryer and have a heat enclosure. I’m starting to run out of ideas on how to fix this. Any suggestions? The pic is how it starts and that was just a brim since I used to always use a raft and thought I should try that instead.

Edit/update: after spending the better part of a week just troubleshooting different suggestions I have found what I think was the main culprit. The filament I was using seems to be of really poor quality. I switched back to a glass bed with glue and could get the hatchbox yellow I had left over to stick really well after I dried it out, when I tried to dry out the black I was using and switch back to it, it immediately pulled away after the 2nd layer.
