My home switches are induction switches. I connected them with some relays.
The relays are connected to the input pins of my board.
I used pin 10 and pin 11 for homing.
I used a microswitch for the floating switch. This one is connected to pin 11 of my homing.
This is the current hal files.

With this configuration the homing works fine.
If i make this change "net plasmac:float-switch parport.0.pin-11-in-not => debounce.0.0.in"
Then i get the error that the pin is linked to all-home.
If i change all-home to "all-home => debounce.0.0.in"
then i get the error "debounce is linked to"
