Hi, You may need to remove the hot bed and place it in a horizontal position to see if it is uneven.

I have checked that the glass is flat, using a straight edge. And the glass is flat.

Hi, do you have a hotbed under the glass?

yes, there is a heated bed under the glass. My machine is a Pro C.

Hi, have you checked if the hotbed is level? Remove the inspection on the horizontal plane?

I set an on the right track edge on the glass bed, and the glass bed its self is level. The glass bed is held to the warmth bed by bulldog cuts, insufficient strain to twist the glass. I checked the two sides of the glass just in the event that one side was thicker in the middle then the opposite side.
