Storing the Z offset value

[DR8]

Hi,

I'm running 1.18 firmware and I'm wondering how can I store the Z offset value. Now I use the Slic3r function to do this but I want to store the value in the firmware. My currently offset value is 1.8 mm

Thanks!

P.S. What config.json file is good for? Something bad will happend if I will delete it?

You can set it with G31 in your config.g

about the config.json , When using the RRF configuration tool you can create your own individual configuration by creating a new one from scratch or by loading an existing JSON (Config.json) template:

So if I have this:
G31 P600 X0 Y18.5 Z2.5 ; Set Z probe trigger value, offset and trigger height
should I change like this?
G31 P600 X0 Y18.5 Z4.3 ; Set Z probe trigger value, offset and trigger height

because in the slic3r the Z offset is 1.8mm

so actually it should be
G31 P600 X0 Y18.5 Z0.7 ; Set Z probe trigger value, offset and trigger height
and now it works.
For those who still don't understand read this very helpfull article :

DR8 do you then set the Z offset to 0 in your slic3r?
