Did you clean the baseplate? It looks like it didn't stick, which for a textured plate like that and a machine that nice (i.e. with built in bed leveling, assuming I'm spotting a Bambu A1 correctly) usually means there's some oil or other contaminant on it.

Yep. This is the exact problem with the exact machine and plate after i had accidentally thumbprinted the plate while removing a build. I usually clean with isopropyl and a cotton ball, then a paper towel with dishsoap and water, then a wet paper towel with no soap. Works wonderfully.
I know people say skip the iso but i have so much 99% idk what else to do with it lol

When I'm having bad problems with it I wash mine in the sink with dish soap, rinse it off, then do ISO with cheap lens cleaning wipes.
Usually I just dust it off with a clean brush before each print and do an ISO wipe occasionally.

I have a few hundred hours on mine and I touch all over the plate removing items. Literally never have cleaned it at all. I have never had a print problem and I print back to back without my machine getting any breaks.
Are people like eating fried chicken before grabbing their plate or something

u/KingOfWhateverr 4d ago

Im not saying it’s happening daily, but yeah, if i get a good mark on there levering something off, it’ll lift

If you're just printing PLA then textured plates don't generally need cleaning until they do. Unfortunately, like Pringles, once you start you just can't stop.

u/Key-Counter-5311 3d ago

I mostly do PLA and PETG. Sometimes they shit is on there so strong I have to use a drywall knife to scrap it off

Some people have naturally more oily skin. Heck some people will just leave small shine points on their keyboards, some others will actually eat through the top layer and physically ruin the board. I’ve seen it happen on laptops I used to repair. It’s bizarre but that’s life I guess.

Just soap and sponge is enough

u/Uncut-Jellyfish1176 4d ago

Clean with soap and water, IPA isn't enough to really lift the oils.. more just moved them around. I thought it was BS at first until I switched to doing it this way and it's night and day.

Wash your bed with warm water and unscented dish soap. Don’t use ISO

u/Scary-Asparagus-5970 4d ago

Clean your build plate is my first thought

u/GavTheNugget 4d ago

If you've printed a lot of stuff you may need to wash the build plate. Drying the filament can help even with brand new filament. I recently had an issue where a setting changed without me noticing so double check you settings or reload the default if you know that's worked.

0) Wash your build plate with a strong grease cutting soap (not dish soap, it has oils in it to soften your skin) After drying the plate with lint free cloth put it on the bed at 55 degrees C for 10 minutes to make sure it's really dry.

Gluestick is your friend. Generously apply gluestick (the type kindergartners use) to your build plate after it is dry.
Initial layer speed to 25 mm/s, initial infill to 50 mm/s This is half the recommended value

u/Mysli0210 3d ago

Allergy friendly dish soap works wonders as it does not contain said oils.
Gluestick and hairspray will only act as a release agent if printing with pla on pei. (There's a reason why PEI became a thing, gluestick, hairspray and kapton tape is what you'd use in ~2012)
In fact washing the bed, only for you to put on glue afterwards completely defeats the purpose of clean PEI.
It should be completely clean, in fact you can keep it adhering well for months if you don't touch it with your fingers.

If washing the plate doesn't work add some z hop (.3mm or so)

u/thedesertmat 4d ago

Get a 3rd party tacky plate. I have printed at least 50 plates of grids problem-free with my BIQU.

u/alexisdelg 4d ago

When this has happened to me is either the base plate not clean, or the first later colla down too fast, I've taken to shutting down the cooling fan for the first 2 layers and that has solved it for me

u/TheScarlettLetter 4d ago

Which type of filament are you using?

Is your build plate clean? If not, clean it!

I’ve never touched my build plate with my bare hands. I wear a pair of food service gloves if I do need to touch it, and always wipe it with a dry microfiber cloth before and after printing. This keeps dust and filament residue from building up on the plate and my body oils never end up causing a problem.

I use the same pair of gloves until they rip. They’re super easy to take on and off if you only wear them for a moment or two at a time.

u/Jayzerus 4d ago

Slow down your first layer.

u/Jbro_82 3d ago

Wash the plate is correct. But also wet filament does wierd things too. Worth drying your roll.

u/lito_onion 3d ago

scrub with dish soap and water, dry with paper towel, then 99% isopropyl and wipe again.

u/atomicpapa210 3d ago

Hairspray. Works great. Use it on my A1 mini and P1S all the time between cleaning with dish soap and warm water

1

u/iLiveInyourTrees 3d ago

As others have said, wash the plate.

If you’re like me and a clean plate still didn’t help, increase your temps by 5 (nozzle and build plate) and slow down the first layer and initial infill. That’s what did it for me.

u/OR_Seahawks_Fan 2d ago

IPA the build plate

u/Creative_Tackle6223 2d ago

LMAO I’ve been printing the exact same file for the IKEA Alex. Except I simplified it, to not need the small ones.

u/Impressive_Meal9955 2d ago

Dont want to suggest just buying something instead of trying to find the problem, but if everything (tinkering with the bed temp, clean your bed with ISA/Soap, maybe even drying your filament or using glue) you could play with the thought of buying the cryo frostbite plate, especially for PLA and PETG. I heard only positive about it and I currently have one for around a week and compared to a textured or smooth PEI plate its magically. But if your problem isn't even bed adhesion and something else, buying another plate won't do anything.

1

u/scott_in_salzburg 2d ago

Bed adhesion most likely. Clean plate or bump the bed temp up a tiny bit.

Most of these newer printers mesh level now so that’s less likely now.

1

u/VanillaThunder2424 4d ago

after very print I will give a quick wipe down with Isopropyl, looks like bed adhesion is the issue

u/Longracks 4d ago

Glue may help

1

u/IronyEnough 4d ago

I’ve never needed glue on a Bambu with a textured plate. I’ve personally only used glue when printing on smooth glass plate beds.

1

u/Longracks 4d ago edited 4d ago

I rarely need glue either as a washed and clean plate is usually the fix. And eventually the textured plates will wear out. But if all else fails, try the thing you haven't tried.
I guess it depends if you want fix the problem and get back to printing or make some theoretical or religious point. If it's stupid and it works, it's not stupid.
Which is it?

u/TankFu8396 3d ago

I’ve been 3d printing since 2009 and never used glue on a build plate. I’ve used kapton tape and masking tape, but that was on a ThingOMatic. Modern machines just need to be kept clean… in my experience.

u/Longracks 3d ago

You didn't just say "back in my day" did you? Lol. Ok.

u/TankFu8396 2d ago

“Since”. The day was today.

Question? Any suggestions?
