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.

You can try turning up the bed temp, lowering the z-offset to get the nozzle closer on the first layer, or increasing the first layer flow in your slicer. For me the purple glue sticks on a glass bed worked, but sounds like that’s not working for you for whatever reason.
Another trick I’ve seen people use is adding some circles to hard corners like that in the model that you can cut off later.
I’ll need to figure out how to make the mouse ears that everyone suggests. I haven’t actually made my own models before and the brim is automatically made with the creality slicer. I tried cura as well but that was doing weird things with the print if I recall so I went back to the creality one. If I can’t figure it out on there, I’ll see if cura gives me more options for that. Thanks for the info
Find an stl of a disk and then overlap it with your part
Makes sense, I’ll try that out. Thanks!
The creality slicer also has a brim option called mouse ears, but I haven’t tried it out myself, so not sure how well it works. Also, there is an option to bring in basic shapes that you can then adjust the size of within the slicer too. That way you don’t have to find an stl of a disk, you can just bring in a basic shape in the slicer if you’d prefer
