From the Creality website, the print surface doesn't like flex steel (way too flexible), more like refrigerator magnet type stuff with plastic print (PEI?) coating.  Not that durable apparently.  Might be a good to time to add a WhamBam magnet/flex steel with PEX surface to print on. Stuff pops off the PEX really nice, been using it for a week or so now.

What material is the bed composed of? How thick is it? Note, you will probably have to replace it, or at least rotate it so that the nozzle never crosses the bent area.

I'm not sure, it's stock bed came with Ender 3 Pro, are there many kinds of it? It seems I cannot rotate it, otherwise magnetic part will be on top?

Sounds like you wrecked it.  Time for a new sheet of the stuff.  What material needs 240C bed?  Sounds really hot, even ABS only needs 120C.  Website shows Bed Temp <= 110C, how did you manage to reach 240C?  I think by "rotate" was meant as spin it around like a dinner plate and print on a  non-lifted area; rotate was not meant as flip it over.

Rotate means around the z axis, not x or y

@CrossRoads Yes combination of magnet and surface, bed wasn't 240 celcius, extruder was 240, bed was 60. But first layer sticked very hard on surface. I never used that temperature before, I use 210 with PLA+ and works okay but that was a "calibration/test" model.

About rotating, unfortunately lifted area is on center.

BTW, maybe I'm using wrong terminology, right word might be "magnetic sticker", not the heated bed.

# Fixing uplifted magnetic heatbed surface

(Asked by: username_0 on 2019-06-27)

When trying calibration prints, I printed something with 240 celcius on magnetic heatbed and when removing the object, because it sticked very hard on surface, it uplifted surface of magnetic bed.

So when printing first layers, nozzle touches the bed when it's passing on that points.

Is there any way to fix this? I'm thinking about ironing the magnetic bed but not sure.
