Daughterboard inputs not recognized in HALMETER

The post here shows which pins are step/dir (though you don't need to know normally)
Look in the 7i76 manual to see which terminals on the board are step-dir. (if you want you can also see the mapping from 5i25 pins to 7i76 pins there. Or infer it at least, it isn't explicitly stated.

But, make sure that the HAL hasn't set any of those pins to "input" or "inverted" at the 5i25 level.

Thanks Andy. Just having trouble with the limit switches not stopping the homing movement in X and Y now. Z works and homes the cycle just fine, X and Y home in the correct direction but do not stop when the switch is triggered . Ill keep messing around I guess, unless you have some insight.

Sounds like maybe they are connected as limits, but not as homes.
Typically the switch output pin needs to be connected to three axis.N... pins (max lim, min lim, home)

With the limit settings below I get a funtional Z home, XY do not stop when switch triggered. The setting is the same for Z as it is for the others so it doesnt make sense to me. I redacted lines from both below to make it easier to view.

The home switches all should trip when the table reaches -Xlimit/home, -Ylimit/home, and +Zlimit/home

You need a lot more HAL. Where do the debounce.out pins go to?

The full HAL is a few posts back on this thread.

The debounce goes from:

net home-limit-x-raw <= hm2_5i25.0.7i76.0.0.input-01-not => debounce.0.1.in
net home-limit-y-raw <= hm2_5i25.0.7i76.0.0.input-02-not => debounce.0.2.in
net home-limit-z-raw <= hm2_5i25.0.7i76.0.0.input-03-not => debounce.0.3.in

#onwards to

net and-home-x debounce.0.1.out enable-limit-x.in1 door-limit-x-lut.in-0 door-limit-in.in1
net and-home-y debounce.0.2.out enable-limit-y.in1 door-limit-x-lut.in-1 door-limit-y-lut.in-0
net and-home-z debounce.0.3.out enable-limit-z.in1

Could the logic above that links the X and Y to the (nonexistant) door switches be causing issue?
