oh man, this makes me crazy.

When i try net all-home => debounce.0.0.in

then i get the error debounce0.0.in is allreday linked

The contacts i can't change.because the float switch is triggering my home switch then.
i have to invert the float switch signal in plasmac

If you add this line then you would need to comment out the earlier line that links debounce.0.0.in

How are your home switches and float switch wired?

What debounce mean? For what it is?

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"
