What exactly isn't working? What happens? What kind of probe is it?

What type of Z probe is it?
In what way isn't it working?
What firmware version were you running before you upgraded?

Ok, I have my z probe set up and calibrated but for some reason the Z probe reports below 0 when doing a home and bed comp. See attached config files and bed homez.g heightmap.csv config-override.g config.g bed.g map. Again, I have something simple in the configs that is causing this.

@wannathermal Probably best to update to the latest firmware version, 2.05.1 https://github.com/dc42/RepRapFirmware/releases/tag/2.05.1

Your probe settings from your config.g:

M558 P1 F120 T6000 ; Set Z probe type to modulated, the axes for which it is used and the probe + travel speeds
M574 Z0 S1 ; no Z endstop, active high
G31 P500 X11.0 Y5 Z0.51

This is for an unmodulated or smart IR probe. Is that correct? What probe do you have? Normally you would have an 'H' parameter, but it will default to H5. See https://duet3d.dozuki.com/Wiki/Gcode#Section_M558_in_RepRapFirmware_2_x_and_earlier
Maybe try adding I1 to invert.

@wannathermal Is 4000 steps per mm correct for Z? M5 threaded rod for Z axis? What printer do you have?

M92 X80.198 Y80.198 Z4000 E2100 ; Set steps per mm
