Filament sensor assignment problem

[laptop-laptop]

Hello, I am using a Prusa i3MK3S+. The filament sensor is connected to an Einsy Rambo board at PK0.

As mentioned in Step 4 of the Installation, I assigned the filament sensor using

switch_pin: !PK0

in flap_main.cfp and commented out the section for "button for unloading".

Klipper gave an error:

pin PK0 used multiple times in config

I went to /config/klipper-prusa-mk3s/mk3s to comment out the switch_pin: !PK0 in einsy-rambo.cfg but then it gave another error:

Option 'switch_pin' in section 'filament_switch_sensor fsensor' must be specified

I got the einsy-rambo.cfg file by following the steps in: https://github.com/dz0ny/klipper-prusa-mk3s

Please help.

pin PK0 used multiple times in config

Check your klipper config for PK0 because it is being used more than once. You likely have to commented out part of the config you're using.

Thank you. What part of config should I comment out? As mentioned, I found another mention of PK0 in /config/klipper-prusa-mk3s/mk3s/einsy-rambo.cfg but when I commented it out, I got other errors.

Is there a way that I can use your codes but have the switch_pin: !PK0 commented out and defined somewhere else like /config/klipper-prusa-mk3s/mk3s/einsy-rambo.cfg in my case?
