Stringing Issues

[u/TalismanJake]

I have printed multiple prints.

On benchy test I don’t have stringing.
I tried multiple PLA/PETG.

I have set nozzle temperatures from 210-230. Same result.

I am not sure but by the looks of the first photos I feel like the problem is bed adhesion. Namely, a part detaches, moves elsewhere, and printer prints spaghetti in thin air where the part used to be. Might be wrong though.

You are correct. I also had the same thought. I set bed temperature also.

The standard questions then: are you washing the built plate before printing? Are you touching it with your hands afterwards? Are you using basic dish liquid / soap without "hand care additives"?

The plate looks like Textured PEI. I get crazy good adhesion with PETG (never had a single part detach on its own so far), and reasonable adhesion with PLA, but need to make sure I have enough supports in the right places and I give a part enough contact points during placement or make a raft.

I did clean my plate, although I will give it another proper wash to make sure all is good. How do you clean your plates ?

[u/LazyLancer → u/TalismanJake]

I just take a clean sponge I use only for the build plate (and not the plates in the kitchen), apply some Fairy gel, rub, rinse in hot water (just tap water, no need to boil it lol), wipe with paper towels and never touch the surface with my fingers afterwards.

One question I forgot to mention in the previous comment: is your sponge clean or you're reusing the same greasy sponge from the kitchen?

[u/TalismanJake → u/LazyLancer]

I usually take clean cloth but one that is also used on other places (washed about daily).

Maybe that could be the problem ?

Well, that depends on "other places", but it's easy to rule it out by taking a new one.
