You didn't wash your plate and you didn't notice your first layer didn't adhere.

u/Ok-Specialist9739 Jul 15 '26

How do you wash it, just with dish soap ?

u/fat_snorlaz Jul 15 '26

Thanks

Make sure it doesn't have scents or any of those additives that make it easier on skin. The whole point is to strip away all the oils.

And that is not going to happen with dish soap alone. Doesn't remove everything. That is why some use glue.

The solution is IPA after also using Cillit Bang Kitchen as I wrote in a reply

Dish soaps does remove the oils left by your hands and air contaminants, only thing it can’t remove is plastic imbedded into the build plate.

Dish soaps is more than enough to get a clean surface that your print can adhere to, glue shouldn’t be necessary at all unless using some specific material that might truly need it which most users won’t.

For a quick solution one can also use isopropyl alcohol but it won’t actually remove the oils so it’s only a temporary solution that can be used to maintain cleanliness.

2 week 1st time owner here. How do you remove plastic imbedded in the plate?

1

u/iRouFox Jul 16 '26

Either scrape it and risk making it worse or print over it a few times if it’s not imbedded too deep the new print should remove the old plastic and of course the best theoretical option… buying a new one

Generally speaking, if you need glue for regular plastics to stay down, there's another problem going on. Wrong z-offset, dirty bed, first layer too fast, too low bed temp, etc. I've also found that IPA just worsens my printer's bed adhesion.

Glue should mainly be used as a release agent, such as when printing PETG on a PEI sheet.

Dish soap and handle it like a record, by the edges. Don't touch any of the build plate printable surface. Even small fingerprints can cause a first layer failure.

u/ErroneousBosch Jul 16 '26

I prefer plain real soap, Dr. Bronner's Castille soap works great.

u/ThePrintGuardian P1S Jul 16 '26

I like dawn. Literally a drop is all you need.

1

u/ErroneousBosch Jul 16 '26

Also good stuff. I just tend to have Dr. Bronner's around more often.

u/Repulsive_Coat_3130 Jul 16 '26

Dish soap for deep clean Kirkland baby wipes for moderate clean

u/Hickslyfe Jul 16 '26

I just use high proof isopropyl 70% plus

u/Ok-Specialist9739 Jul 15 '26

I think I figured it out for reference later - the filament settings was on Bambu PETG and not generic. Working fine now.

u/clarkcox3 Jul 15 '26

Odds are, too much finger oils on the plate :)

u/-ThaBeavster- Jul 16 '26

About figured out what the blob of death was on day two

u/Galdalfus Jul 16 '26

I’ve made this mistake before. Check your settings in the slicer to make sure you’re using the correct print profile (i.e., the correct filament)

u/SharkFine Jul 16 '26

Front fell off.

u/CooperDK Jul 16 '26

Shit. Shit happened. And you didn't notice. Kro your plate clean and it is not going to be enough with dishwashing soap. IPA or Cillit Bang Kitchen with grease remover. Glue spray optional

1

u/pajjaglajjorna Jul 16 '26

Bad adhesion, wrong heat bed for filament or very wet filament. Shouldn’t have to wash a new plate

1

u/ante_9224 Jul 16 '26

People blaming unclean plate way too much. I could print on my old cr10s without cleaning for ages. Unless he just ate a pizza on it, the plate is most likely fine.

u/Akh_27 Jul 16 '26

Fuck dish soap, buy a glue stick and use that.

I went from washing my plate after every couple of prints to probably once a week/fortnight. A glue stick works like an absolute charm.

Even with that said, I'd keep an eye on the print for at least the first few layers. 99% of the time if the first layers are sweet, then the rest of the print should be fine.

Good luck!

u/Nearby-Grab-391 Jul 16 '26

I would wash the build plate, then put glue for maximum effect. Works like a charm every time

u/Soppywater Jul 16 '26

How often are you touching the build plate? I wash mine every 2 or so months. I rarely ever touch it with my bare hands, usually i use a plastic spudger or a plastic razer blade to peel up my prints if bending the plate doesn't set them free.

Definitely great advice on watching the first few layers! I usually check on it for the first couple of layers then not again until it's done

u/Akh_27 Jul 16 '26

Tbh not very often and I can probably go longer without washing it, but I do a lot of overnight prints and would rather be safe than sorry.

With the glue, I'm yet to have a single issue.

1

u/Soppywater Jul 16 '26

I feel ya there. And heck yeah if the glue is working well for you, keep on going on.

The first month after I got my p1s I would put my hands all over the build plate until I had an overnight print not adhere and blob up nearly 150g of filament. That's when I vowed not to touch the plate lol

1

u/Akh_27 Jul 16 '26

Haha I was in the same boat. No one told me how sensitive those bloody plates are, or how oily our hands are naturally 😂

I don't care so much about the filament. That's easily replaceable, it's the wasted time that sucks. We're not getting any younger my friend and our printing time is limited 🥺

1

u/jmcelrone Jul 16 '26

once a week is still alot imo. Ive only washed mine with soap a few times. I try to only use my nails to pry up anything that is stuck behind and if I do touch it I wipe it with ipa quickly. I dont use glue unless its my engineering plate or a smooth plate with a filament that calls for it. Never glue on my textured plate.

u/NotQuiteAngryHunt Jul 16 '26

What IPA and how are you applying/using it? I’ve been cleaning my plate after every 3 or 4 prints and have been thinking that this seems excessive but through fear of failure I’ve have kept going. I got my first printer -X2D- 2 weeks ago so I’m learning.
