combined x/y axis home switch

Hello,
i have a machine with home switches for the x and y axes that share input pin 15. the switches are located at xmin and ymax.
The z axis has its own home switch located at z max.

i found settings witch shared pins for all axes but not for just two of them.

i tried :
net max-home-y <= parport.0.pin-15-in
net min-home-x <= parport.0.pin-15-in

but got an error that the pin15 is already connected

how do i configure the hal file for shared pins for x and y axis?

many thanks,
Joa

ok many thanks,
i understand the or function is useful for the case when i want to use two input-pins to trigger the same event. i need one input-pin used for two signals...
but i am sure i got that wrong....

i managed to get x and z axis referencing in the right way but not the y axis.


my ini and hal files are attached

many thanks,
joa

There is no need to use more than one signal for this. One signal can be connected to the multiple inputs as needed.

net limit-home-x-y <= parport.0.pin-15-in

net limit-home-x-y => axis.0.home-sw-in
net limit-home-x-y => axis.0.neg-lim-sw-in

net limit-home-x-y => axis.1.home-sw-in
net limit-home-x-y => axis.1.pos-lim-sw-in
