Z offset -> please help

[obsidian oracle]

Hello, I printed today and changed the z offset in klipperscreen. The value before was 2.9. I changed it and saved it, so in the config the 2.9 value is now outmarked, but where is the new value? What need I to do to get my original value like it was before?

here the config

if you use "SAVE_CONFIG" (this is the function in klipper itself to safe changed values), klipper will outmark it in the config and add it at the end of your config file. in the section with this header:

#*# <---------------------- SAVE_CONFIG ---------------------->
#*# DO NOT EDIT THIS BLOCK OR BELOW. The contents are auto-generated.

if you look at the end of this secion, you will see this:

#*# [bltouch]
#*# z_offset = 2.900

this is quite normal in klipper.

ok thx, that means now, it uses actually 2.9?

[elfin wadi]

yep. klipper read the config from the top to the bottom. if you have multiple times the same attribute in it, it will use the last one. i dont checked if you have above another value, but because of the value here at the bottom, it will be z_offset = 2.900

k thx

@elfin wadi i did longer not print and forgot some things ^^ what i actually think about is, i use auto bed leveling with a bltouch, so it measures the bed every time before printing, should it not automatic set an z offset? why there is a z offset value in config?

[elfin wadi]

the z_offset is the difference between your bltouch and your nozzle. this cannot be mesured automatical.
