I have leveled all 4 corners of the bed but the center sags leaving 4x the gap of the corners. When I run a large print the first layer will not adhere in the middle of the bed.
I ran auto level to measure the entire bed but when I run a print the Z-axis does not move up and down to compensate for the sag in the middle. How can I get the auto level to do its job or how can I level the middle of the bed?
@kevin Thanks. My bed is similar to yours with a droop in the middle. I figured out how to adjust the z for auto leveling. It now appears to be working. Appreciate the response.
