Cartographer initial Setup problem

[RobAndroid]

Hello everyone. I have a question. I have installed the Cartographer on my Voron 2.4. First i had a problem the sensorless homing issue for X/Y. I start the process as described with G28 X Y. Then I have to enter G90 and start with G0 X150 Y150. Next I start CARTOGRAPHER_CALIBRATE. It shows me z = 4 as coordinate and I move the nozzle closer to the bed. But I don't get close enough to the bed and I get the error that I am in minus or my z is too low in the coordinates.

After homing, the gantry is also approx. 140 mm away from the bed I wanted to start the calibration. The position is displayed with Z = 4.0. I can't get the nozzle closer to the bed. I suspect a config error. Does anyone have any experience with this? PS: I use sensorless homing with a config intended for this purpose. Maybe the error is already here.

Try setting your position min to a negative value in your printer.cfg

Thank you very much. I now do have a z-offset = -3.930. Position of my toolhead now says x= 150 y = 150 z= 434,000 although it is right above the print plate. Endstop Z still triggered after going through calibration process and the SAVE_CONFIG Prompt.
Homing z fails into the error that the default model was not found.

Here is my Cartographer section:

I had several issues. Until I find this steps and follow it.

once i got my printer on i ll send my configs.
But this looks like a config on z lift
For calibration :

Calibration | Cartographer 3D

Thanks i am now at the point, that i have my z offset but it does not home. It says "No cartographer model loaded" i was going through the calibration process.
Thats my save for the model

Thank you i resolved it. I had to delete This part #*# DO NOT EDIT THIS BLOCK OR BELOW. The contents are auto-generated.. Now it works

Hi! I am suddenly facing this issue where i can get the Z offset but model is still not loaded. It is also saved in the config file but in console I get this,
