Unresolved unable to print against the bed

I know this has been answered before, but I cannot find it. I have reverted my printer to a standard RAMPS board, set up independant Z steppers and switches, installed the mesh enabled firmware, installed a titan and v6 hotend, and have a clean sheet of buildtak down so I can print PC-ABS without struggle. It has been reassembled recently and manually calibrated.

and I cannot get it to print against anything. It's always up in the air.

If it helps, here are my M501 results.
