I can not see the wood for the trees. Version 2.8
I am not seeing what is wrong with the homing hal and ini files attached. System is a mesa 7i92 with a cheap Chinese bob and a simple db25 connector breakout (no optos) to the drives. the home switch is NC
When I try to home one of the axis (say X) the switch does not stop the axis moving.
Looking with halmeter signals min-home-x changes state and gpio pin 030 changes state when the switch is pressed.
What am I missing?
Edit I have also tried net min-home-x <= hm2_7i92.0.gpio.030.in_not

That will have to do something with the naming of pins, had the same problem lately with enable, so have a look at the docs for the version you are using to check if the pin and signal names are the same, also upper case and lower case must be same.

# external input signals
# --- HOME-X --- on bob pin 10
net min-home-x <= hm2_7i92.0.gpio.030.in
^^^^^^^^^^^^^^^
...........................................
# ---setup home / limit switch signals---
net home-x => joint.0.home-sw-in
^^^^^^^^^^^
As Tom mentioned, Inconsistent signal names
# --- HOME-X --- on bob pin 10
net min-home-x <= hm2_7i92.0.gpio.030.in
^^^^^^^^^^^^^^^
