AutoBim asking for the bed to be higher than possible

When using AutoBIM, it is asking for the knobs to be turned more than possible because it is already as high as it goes. I have already tried to move the z-offset and that didn't help. Is there a way to lower what AutoBIM wants to be zero so that I can level the bed "lower"?

I would screw the bed screws down to about 50% screw length before starting autobim
That should give you enough room to level your bed.
