Homing switch setup in hal

Hi...I have a mechanical home switch wired as seen from others but does not seem to be functioning...I am not sure I have hal right for x home switch...I have pin # 2  from mesa 7196s going to nc on switch...Input common to 24v ground on  power supply  and switch common to 24v power supply v+...I am not very good with electric so any help would be greatly appreciated..

Thanks,
Rick

TB3 pin Pin 2 would be GPIO 01 (but actually you should be using INM pins, not GPIO)

Pncconf setup would be something like:

 


(invert it using NC switches)

You should also use halshow to verify home switch operation before attemting to home

Hi...I used pin that is labeled iN2....and put in Hal as GPIO 002....when I tried to test in Halshow nothing happened....i checked wiring seems ok....I did not know if i am missing something in Hal...I only put  info  in the x axis section...
.
# ---# external input signals...under this part it is blank..


setup home / limit switch signals---
net x-home-sw <=  hm2_7i96s.0.gpio.002.in_not
net x-home-sw <= joint.0.home-sw-in

Thanks for reply!!

Does the yellow LED near IN2 operate as expected?

I forgot about that.....no

if I go to V- instead of power supply ground IN2 lights...is that ok? or does it indicate a different problem?

So all is working now....thanks again for your help...I am not sure what INM pins are...would I need another board?

Thanks again!,
