building platform

[schiaucu]

Hello, on the Geeetech Prusa I3 x that I brought three days ago, the aluminum building platform is not even, they are about 0.5mm difference from the corners to the center so the calibration and the printing is impossible. Have you a solution for this situation?

Thank You very much.

Thank you I have installed an ordinary 3mm glass and it's working perfectly. I was afraid that will broke under the heat but it's still in one piece.
