I dont know what im doing wrong

[fleet holly]

I tried to print out a shape on my ender 3 v2 neo and halfway into the print the shape just didnt stick to the plate and started "moving" around the print bed and also it gives me some weird strings
This is the second time i tried to print this shape but the same exact issue happened previously

It sounds like you are experiencing two separate issues with your 3D print. The first issue is the print not sticking to the bed, and the second issue is stringing.

For the first issue, ensure that your print bed is properly leveled. Use a piece of paper or a feeler gauge to make sure there is a slight resistance between the nozzle and the bed. Also, try using a layer of adhesive such as glue stick or 3D printing bed adhesive to improve adhesion. If these steps don't resolve the issue, you may need to clean your bed with isopropyl alcohol to remove any residue that could be interfering with adhesion.

For the second issue of stringing, it could be caused by excessive filament oozing between print moves. You can try reducing the printing temperature slightly to prevent excessive filament flow, or enable features like retraction or coasting in your slicer software. These settings help to reduce stringing by pulling the filament back when it's not needed.

Did you wash your bed with soap?

dish soap?

[fleet holly]

Yes i even used antibacterial spray

[slate robin]

...

[fleet holly]

And a microfibre cloth

[slate robin]

............

I think you misunderstand the purpose of the soap.

The soap is to remove oils.

You don't need a microfiber cloth, you can scrub the hell out of it with a sponge.

[fleet holly]

Oh

[slate robin]

Just, not a metalic sponge.

What material is that? PLA?

[fleet holly]

Pla +

[slate robin]

What temperature do you have the bed set to?

[fleet holly]

70

The nozzle was 215

[slate robin]

Have you tried at 60?

[fleet holly]

Hmm i didnt

[slate robin]

Go for 60. PLA is usually around 60, but PLA+ is even easier to work with in most situations, and in that regard, I don't see it requiring any more than 60.

[fleet holly]

I wonder what could caused the stringing issue

But thanks for the help

[slate robin]

Stringing is usually caused by temperatures being too high, or cooling being too low. Especially with PLA+

I'd also double check your Z-offset.

Make sure the nozzle is laying the plastic on the bed, not above it.

If you still have adhesion issues, there are two methods you can use

First one is gluestick. Apply a coat of gluestick in one direction on the build plate, let it dry, apply another coat the other direction, let it dry. After your print, you can remove the gluestick with water.

Second, you can spray the bed with hairspray. It tends to help with adhesion.

Do you know the material of your build plate?

[fleet holly]

Its the basic build plate that you get with the ender 3 v2

[slate robin]

Is it glass?

[fleet holly]

No its somekind of a metal with a coating on top of it

[slate robin]

PEI?

That's good.

Well, if it is PEI

Though, I have no idea if it is or not.

[fleet holly]

Chatgpt said its somekind of a glass buildplate with coating in it -_-

[slate robin]

This is what a PEI build plate looks like typically.

yours looks different.

In that case, I'd suggest using either the gluestick technique, hairspray technique, make sure your build plate is free from oils, especially if you've touched it a lot, lower the temp to 60....

That's all I can think of

[fleet holly]

Thank you

[slate robin]

I don't know if the printer you have has a magnetic bed to hold a metallic buildplate with PEI coating, but one day in the distant future, when chatGPT takes over and robots control our lives more than they already do, you might consider upgrading the build plate to a textured PEI metal sheet.
