While the opposite corners are warped a little, the problem is having a center that is warped. It is strong enough that it makes the glass warped ...

Yes, I realize that. Even with the glass clamped on, there is still distortion. The glass is 3mm thick and is warped when clamped to the heatbed but not as bad. When .1mm difference in bed height matters for getting good prints, this is still outside of tolerance.

Upon further inspection, the center is raised about 1mm to 1.5mm when viewed through the hole for the thermistor. I have ...
