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.

Cleaning is a good suggestion. I'd start there.
Also, that kind of looks like the cheap black textured plates that come with some printers. I thought the people talking about pei sheets were over-hyping but honestly they are really much better. It's not a silver bullet but pla sticks soooo much better to them.
For pla it's overkill, but for tricky stuff build adhesive can help. I had good luck with vision miner. It's expensive but it's been buy once, cry once because it has lasted a really long time.
I’ll definitely take a look at the pei sheets, that’s the first I’ve heard of it. Thanks for the suggestion!
