Correction of heightmap is not really working
-
Where are you executing the G30 at the center of the bed to set the Z=0 Datum?

@fcwilt
Yes, that is where we are executing it from, the center of the bed. -

When are you doing that?
In what bit of code are you doing that?

@fcwilt
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. -
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.
