i am using the last stable 1.19.2 i think. thank you very much i will try that.

Hi
I am using my own custom 3d printer and i don't use any probe. So i face a problem as regard the first layer.
My heat bed is stable without springs , i use spacers. The only way to make my printer works is the mesh bed compensation.
So i would like to ask if there is any way to build with manual measurement a heightmap.csv.
As i know the heightmap is a csv file easy to edit in excel but i can not find the format or any ready heightmap to download and edit.
Can anyone help me?
