Correction of heightmap is not really working

We are running the z-offset calibration with the G30 in it
after we run the z probe calibration

OK I see now.

A few things to mention:

For the other person I had shown how to use a variable to set the G31 Z Trigger Height setting. You have created the variable but I don't see that you are using it in config_probe.g.
Using the variable is optional. If you are not going to use it in config_probe.g then you can remove any other code referencing the variable.
You mention using the formula to move to the center of the bed with Z0 added. But you show it after the F parameter without a comma separating from the F parameter. I don't believe it actual does anything without the comma. What was the intent of executing this command?
Anytime you change anything in your config_probe.g file you need to be sure it is executed before you attempt to use the new setting(s) in the file.

So I don't switch out build plates, Just run a lot of the same material.
I know he wanted that extra part to change out plates.
So how do I need to change that.

@fcwilt

So I need change my config_probe.g Z setting back to
global.g_probe_z_trigger
like this

; config_probe.g
; config the probe and call the other files.g
 
M558 P9 C"^zprobe.in" H5 F120 T6000 A1 R1
M950 S0 C"duex.pwm5"
G31 P25 X0 Y-30 Z{global.g_probe_z_trigger} ; set Z probe trigger value, offset and trigger height (larger value is closer)G31 P500 X0 Y-30 Z1.73

You don't need to use the variable I all. I don't use one. I just have the constant value for the Z Trigger Height parameter in my config_probe.g file.

If you want to use the variable then make the change you show to your config_probe.g file.
