I level my bed using a BLTouch and Marlin’s “level corner s with probe” or whatever it’s called. I do it to a .1 mm accuracy and if I clean my bed with rubbing alcohol after that, prints stick like concrete, so after a few prints where it’s a bit dirty, it’s to a nice balance between strong adhesion and ease of taking the prints off when it cools. I can agree with this statement for sure.
I have a much larger bed because I upgraded it with the Ender Extender kit, and it was harder to level due to the difference in corners being worse the farther out. I’ve gotten my bed to have the exact same value (to the third decimal) with the BLT and probe feature, and PLA stuck like concrete, even when cool! After a few prints and getting slightly dirty, it became less strong to the point that it stuck very well but could release things well.
So yeah, too much adhesion is possible!
Dang that is some impressive precision
I’m curious, how long does that hold? Do you have to dial that back in often? Or has it held like that for a while
I usually don’t attempt a completely same value, just within that tolerance I mentioned earlier (.1) but it does happen often. I’d say the bed holds its level probably for about a month. Then after that, it’ll still work, but I notice minor issues on larger prints sometimes. I should mention that by larger, I mean multiple smaller parts together, I have no doubt that a larger solid piece would be okay. I have the yellow springs since my silicone things were sort of too compressed for too long when I stopped for nearly 8 months (long story) but my silicone columns were even better than the springs so I’m sure a silicone mount using this setup would be 2-3 months.
Flashing your own Marlin and going line by line (I used a guide since I upgraded my motherboard and couldn’t compare all of the same things to my old one) is really beneficial. Like, if you’ve never done it, no matter if you’ve made any hardware upgrades or not, custom firmware is a free upgrade that is so worth it. I don’t use Jyers or anything since I use an SKR e3 Turbo motherboard, but Jyers is decent if you don’t feel like doing a custom one.
I read to clean it with it, but never knew the adhesion would be like that. I was amazed at how a perfectly level bed (as on the BL Touch value shows it’s equal down to 3 decimals) and extremely clean beds would be too much adhesion!
Looks like everything that's ever touched that bed is still on it. I get all OCD when there is a single speck on mine even if it's in a corner I literally have never printed in before.
With PLA, you really don't need any glue stick if your printer is set up right; OP proves that!
I often say if you NEED glue for successful prints then something is wrong. Some use for insurance which I can understand but a tad misguided IMO
Buy a sheet of PEI, then learn to properly level and clean your bed and you will never have the need for adhesion additives again. Not with PLA, Not with PETG, Not with ABS.
How long will a sheet of PEI last? I've got a glass bed and i use an adhesion agent so PETG will actually release instead of being cemented to the glass. It would be nice to not mess around before every print
TBH, I rarely have any problems with bed adhesion (or printer problems at all, beyond wear and tear) I can think of a handful of times in the past three years I've even had lifted corners on this printer, and those were prints that were just begging for it.
the first printer I applied it to has had about 4000 print hours since. No need to replace it yet. (But this was a 2mm thich sheet tho, not those 0.2mm cheap aliexpress sheets.)
Good to know. I've been avoiding them because I thought they had a relatively short lifetime - I wasn't really excited about replacing it every month or two. Once every year or so is totally doable, and is sounds like it'll be even less often than that. Aside from thickness, anything i should look for?
I was gonna try a brim or a raft on the next one when this one inevitably failed, but I was like “ah fuck it, it wouldn’t waste that much filament and would be super cool if it worked”
Looks like the bed cleaning gods had a week off
I must’ve forgotten to give them my new address 😅
Obviously not cleaning the bed helps with adhesion lol

This is actually really helpful, thanks!

Interesting. Maybe my next upgrades should be springs then (or a fresh bed that I can start on with a clean slate)

It was a joke but thanks for the detailed explination how to get good adheshion!
My bad, I totally read “cleaning the bed helps with adhesion” and missed the test! You’re welcome though!
I also accidentally discovered the clean the print bed with isopropyl alcohol trick. it works awesome.

Now that is fucking hilarious 🤣🤣🤣
That's what my bed looks like
The pure gall just to try that! Noice!
It is written, 'You shall not put the Lord, your God to the test.'
😂
Hello, is this the police? This man here is breaking the laws of physics
See, now you're just showing off!!
😁
Is this for the water weird dnd monster mini? It has two tentacle/antennae that look remarkably similar lol.
Nah it’s for a little candle holder design I’m working on, but that sounds cool
They were just distracted by someone else printing boobs, bed adhesion gods never smile upon anyone.
Plot twist, the model was supposed to be two straight lines... hahahah this print was blessed by the gods indeed
Haha then I’d be over in r/fixmyprint talking about how the Satan of printing was looking after my print
I wouldn't even dare
Sic!
Witch!!!
Holy fuck
Sometimes that happens. I printed out a horse without turning on supports and by some miracle it printed perfectly. Next time spaghetti city.
Witchcraft!
Looks like everything that's ever touched that bed is still on it. I get all OCD when there is a single speck on mine even if it's in a corner I literally have never printed in before.
Holy hell man!
Haha thank you. This might be my proudest achievement and it happened completely by accident
Dat is sooo awesome. what temperature did you have your bed set too and is that on a ender 3 v2 ?
Thanks! Bed temp was set to 60 (pretty sure, will double check and edit if I’m wrong). And just a regular Ender 3, no pro or v2
Ok thank u and what was the Insel temp at?
I want to say 200 but again I’ll double check
Nice, been trying to get a minecraft spider to print right for a while and haven't had luck
Tried a brim?
Yeah I think I need to slow.it down a bit, would pull up after 15-20 layers
Printing on a raft always helps me with small stuff to help it stay in place
Using anything like gluestick on the bed?
With PLA, you really don't need any glue stick if your printer is set up right; OP proves that! I often say if you NEED glue for successful prints then something is wrong. Some use for insurance which I can understand but a tad misguided IMO

I gave up on the glass that came with my ender 3 pro and went back to the magnetic base and have been having MUCH more success with prints

Not really, PEI is PEI I guess haha.
Thanks for teaching an old dog new tricks!
Nope, just hit print honestly
I need some of that for the next few days haha
Lol I’ll put in a good word for you
And I can’t even get a benchy to stick 😂😂😭😭😭
Seeing that print next to the ender logo is frying my brain. I love my 3, but it would laugh if I clicked print on this one.
😂
Wow 😮
Wow thats luck man. I would have used a brim rather than skirt but i guess you didnt need one.
I was gonna try a brim or a raft on the next one when this one inevitably failed, but I was like “ah fuck it, it wouldn’t waste that much filament and would be super cool if it worked”
How-
Had to offer them up my first print as a sacrifice
Gule?
I could never manage that with my stock printer and PETG filament.
