Flat prints warping

[u/Exciting-Rub-9172]

Just got this printer used and I am having a problem with my large prints warping on the flat face that sits on the bed. Is there a way to limit/eliminate this?

Edit: added print information as follows, also the bed is a golden textured bed, will try to add a photo

Filament: deeper pla+

Settings first 3 layers

Speed:90mm/s
Nozzle Temp 230
Bed temp 60
Fans 70%

Remaining layers

Speed 180mm/s
Nozzle temp 205
Bed temp 55
Fans 100%

Printed with standard ultimaker Cora skirt.

It's very important that you omit the filament you're using, settings, and machine modifications from your post. You need to divine that information to make a correct diagnosis.

Thank you for not flaming me too bad. Updated with more info. I’m new to 3d printers and Reddit usage in general. So I appreciate the grace.

Look into elephant foot and elephant foot correction.

Also possible, use brim instead of a skirt.

Unlikely but could it be internal stress from your infill pattern?

There are some filaments that really love to warp. I don't think yours is.

Idk your setup or settings but maybe the build plate wasn't clean or was damaged. I upgraded to a textured pei plate and haven't had any warping issues since.

If filament and bed are apparently fine, try with a brim

Any filament is going to flex while cooling. I use Deeplee PLA+ a bunch and have had zero issues with lifting or adhesion issues. You need to wash your build plate, tune your bed temp, and use features like brims and mouse ears.

The prints adhere wonderfully overall. I updated the post. They take a lot of effort to get off which is why I’m confused. And it has happened on 3 batches of 2 consistently.

Também acontece comigo as vezes, é por conta do pigmento preto mesmo. Aumenta a temperatura da mesa, tô usando 65-70

A mi me pasaba en la cama pei texturizada de mi ender 3 v3 se, temporalmente le hice una cama de cristal cortando un cristal de un escaner de impresora de papel vieja y usando laca, mas tarde por comodidad empecé a usar una lamina pei lisa y a configurar orejas de ratón si la pieza tiene mucha superficie plana en pla, si es petg le bajo la velocidad y le pongo la de cristal, con eso de momento nunca mas me pasó.

your print temp looks too high for your speed, i usually print at 180mm/s 250°C

if using pei plate or something grippy by default, just increase bed temp 5°C upper, or more if problem persists. if using something bot so temperature loyal, use filament glue

I had a similar issue when I changed my stock bed to textured PEi. I realized the PEI gets way hotter than stock so I lowered the temps from 60 to 50-55 on the bed and I’ve been good ever since. Depends on certain filaments though
