Official Tempered Glass Build Plate not flat
on my Ender 3 v2, the glass delivered with printer is not flat, is like bowl (the borders is higher than middle) when it's hot.
I have bought the official Tempered Glass Build Plate on Creality web site, but it's not flat and when glass is hot (60°C - 140°F), I have wave.
I need use a mesh 12x12 to print.
Is somebody have same experience?
Or it's me, I don't use right something?
Get rid of the ender 3 v2, I had one for about 2 weeks and got rid of it, and bought a real 3d printer, I'm not sure if I can mention the name, and all my problems are gone. Now I enjoy 3d printing
