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.
This really doesn’t look flat enough for a brim. Is your nozzle close enough to the bed?
I did level it using paper and using the crtouch. I’m not sure how I could get it any closer
Paper levelling is not an exact method, you might need to manually adjust the Z offset depending on how the first layer looks. It’s also something you generally don’t need to do if you have a probe like crtouch, as it will be used to ensure that the nozzle is at a consistent distance from the bed everywhere, and the Z offset will decide how big that distance should be. Just be careful when adjusting the Z offset so you don’t end up ramming the nozzle into the bed, make small adjustments. If you put a lamp behind the printer you can visually check if the nozzle touches the bed, e.g. if you manually move the nozzle to 0.2mm height after adjusting Z offset, can be good to do a manual check before starting a full print.
Unfortunately your photos are too blurry to give feedback, but if you want to you could try this: Print only the first layer for something simple and stop the print. Get a couple of strong lamps and put them next to your printer. Move the camera as close to the print as it can focus, could be around 20cm for a phone camera. Steady the camera against something solid, for example a stack of books.
If you want to keep trying to level on your own, perhaps this infographic could help. SuperSlicer has a built in calibration wizard which might also be useful.
And some general questions which might help troubleshooting your issue:
Its honestly really hard to tell with this picture. If you send a better-lit picture of a brim using a lighter-colored filament, we might be able to provide better help!
But something definitely looks off. It looks very thick and very uneven to me, but I also have no real sense of scale with this picture.
In any case, if this is your brim, the mouse ears and other similar proposed solutions won’t change anything.
use a few mm of brim
That is the brim, according to OP.
lol make that brim a couple dozen cm then!
Yeah, that was about 5 minutes into just printing a brim.
did you get it figured out yet? Adhesion is bad there, maybe you can move it to a different place in on the bed in the slicer? did you try giving your bed a good dish soap wash and then wipe it with alcohol?
or add a 10 level skirt to trap more heat?
I have heard of people using painting tape to stick it to the bed when doing long prints that start coming up like that but that is lame
if thats an endor, do you have a glass sheet you can try printing on?
I’m working on it right now to try out some of the suggestions people have given me. I’m waiting on a thermometer to come in so I can make sure my printer is giving accurate temps. I’ve had similar issues with the glass as I am with the magnetic, but if I can’t get my current test to work I might try again on glass. Right now I figured out how to get mouse ears on the corners so I’m giving that a shot. I have cleaned it a few times already but maybe I used too high of a percent on the ipa so I’ll try again with a lower percent.
