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.
Because nobody said it yet: wash your bed with warm water and soap to remove any residue (especially oily fingerprints)
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.
Have you tried adding a brim or mouse ears to remove later?
The picture is actually the brim of the print. It hadn’t actually gotten to the first layer yet. I’ll have to figure out how to do the mouse ears since that seems to be a common suggestion.
Some slicers can add mouse ears automatically along edges where it’d be likely to lift up. I believe it’s been a feature in orca and its derivatives for some time. Otherwise you can add very thin, single layer cylinders to the corners. Most slicers out there have features to let you add common primitives like that.
