Extreme warping at the front side of the PEI plate

When I came back and Bambu finished the print, it turned out, that I had extreme warping of parts on the front side of the PEI plate. All the other parts, at the left, right and back side were not warped.

I was using the P1P without enclosure and Elegoo PLA white.

Is that something anyone has also encountered in the past?

This can always happen. Use Brim with the print and glue to prevent that. Clean the Plate before with Isopropanol.

Does it only happen where you grab it with your hand?

No, because I usually place the parts in the middle of the plate, so the middle is the location which would be mostly in contact with my hand.

someone already mentioned it, but I will second that. Use the cool PLA plate and cover the entire sheet with a light layer of glue from a glue stick. That will give you the best chance to eliminate warping with PLA.
If you don’t use the glue stick, I find that the parts are TOO DIFFICULT to remove from the plate.

Have had that problem with my p1p from day one until i put the vision enclosure on it with a chamber fan.
I just print pla with the door shut and the sides removed,never had the problem again.
