Klipper Mesh settings (Voron 2.4r1.5) & poor prints with new extruder stepper

Ugh, I believe I have forgotten something very basic and yet I have spent well more than an hour trying to research and try different things but still my bed mesh is very messed up.

I have had this working in the past but now something is very off. Using a Klicky Probe on a Voron 2.4 350mm, I have homed, z-calibrated, QGL, and then performed the "calibrate" from the Fluidd "Tuning" page for Klipper, which is really BED_MESH_CALIBRATE. It seems as though BED_MESH_CALIBRATE isn't taking into account the z calibrate offset or maybe it is something else? I was having errors with using fade (which had previously worked) but I have it commented out now with a very basic bed_mesh.

More of the back story... I replaced the stepper motor on my CW1 extruder because I think I was getting print failures from the janky wiring of the original. When I started printing with the newly rebuilt extruder though my test cubes looked like garbage. Even though the new stepper is a steppersonline version exactly like the old stepper (well the old stepper was a Moons), I thought maybe the extrusion multiplier needs updating and the cause of my crappy new test cubes was poor extrusion. Then when I went to print a bunch of extrusion multiplier test cubes I was having horrible adhesion issues (using ASA and I have had adhesion dialed in for a long time with that same material....), so for some reason that lead me to wanting to check to see if a new bed mesh might help my adhesion and.... here we are. UGH.

Need to tell the bed mesh where the zero reference point is

probe_count: 7,7
relative_reference_index: 24  #(7x7-1)/2

FW version I am running is over  year old.  relative_reference_index was being deprecated. See this thread: 

Yeah, I am running the newer version where the relative reference is deprecated. Any idea how to do this with the newer Klipper version?

It's not gone, it's just been generalized and replaced with zero_reference_position. It's now an arbitrary x, y position rather than one of the bed mesh grid points.

#zero_reference_position:
#   An optional X,Y coordinate that specifies the location on the bed
#   where Z = 0.  When this option is specified the mesh will be offset
#   so that zero Z adjustment occurs at this location.  The default is
#   no zero reference.
#relative_reference_index:
#   **DEPRECATED, use the "zero_reference_position" option**
#   The legacy option superceded by the "zero reference position".
#   Rather than a coordinate this option takes an integer "index" that
#   refers to the location of one of the generated points. It is recommended
#   to use the "zero_reference_position" instead of this option for new
#   configurations. The default is no relative reference index.
