shared limit switch and home get ignored during homing

Using LINIXCNC 2.9.2 on Debian 12 in combination with a Mesa card 7i76e. Both limit switches of each ache are setup in parallel (LJ12A3-4-Z/BX  like NPN) with a pull-up resistor of 100k ohm. My Aches are attached to mesa digital in X => 27, Y => 28, Z => 29. The signal has to be inverted because is up if the limit switch is not used. So far so good. Now configuring my LINIXCNC to have a shared both limit and home together.net both-home-z     <=  hm2_7i76e.0.gpio.029.in_not
net both-home-z     =>  joint.2.home-sw-in
net both-home-z     =>  joint.2.neg-lim-sw-in
net both-home-z     =>  joint.2.pos-lim-sw-in
 The INI contains this settings for the Z-archesHOME_OFFSET = 0.0
HOME_SEARCH_VEL = 2.000000
HOME_LATCH_VEL = 0.500000
HOME_FINAL_VEL = 0.000000
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = YES
HOME_IS_SHARED = YES
HOME_SEQUENCE = 1
 Now to the issue, if I home the machine the limit switches get ignored. This applied to all aches. To simplify the troubleshooting I focus on Z-aches only. If I use a piece of metal and hold it in front of the limit switch the mesa digital in 29 acts as expected, but not the chained signals.

Any advice are welcome.

Try and use the pin 'hm2_7i76e.0.7i76.0.0.input-29' in your hal instead of 'hm2_7i76e.0.gpio.029.in_not'

I did this already, The joint.2.home-sw-in is in this case on and the aches will not move.

The pin for the inverted state would be 'hm2_7i76e.0.7i76.0.0.input-29-not'

you made my day. It works now. Is a bit misleading that PNCconf wizard was defining the GPIO stuff.
