copy this file in the same directory as your printer.cfg

add

[include pressure_advance.cfg]

to your printer.cfg

A [save_variables] block is needed since a printer save variable needs to be used to have it available after power up.

You can skip this if you already have an [save_variables] config block

e.g:

[save_variables]

filename: /home/pi/klipper_config/.variables.stb

I like to hide that file as there is nothing in that should be modified by the user.

Do a klipper restart after adding the stuff above
