The Tormach configs pass the inputs through debounce and look-up tables.

Where are you checking with Halmeter?

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

You could try looking at the 5i25 pins, the signals and the debounce in and out to see where the link is broken.

Im checking at the Input-# pins, not the debounce signals or the home-limit-n signals

Man I sure hope you resolve this! I know you have worked on it forever now it seems. Is there anything different from others running the 6i25/7i76 setup with pathpilot? You would think that by now someone would have made a basic schematic to follow for connecting everything to the 7i76 and just make it a standard configuration and have a solid setup file to be one and done. I'm sure it must be more complex than that I suppose or it surely would have been done by now. Either that or people are reluctant to share once they are up and running.

I would be more than happy to do a schematic for that that anyone could read to wire everything properly and standardize the requirements to make the software side simple and automatic.

Dub, when you get it all working if you tell me your 7i76 connections is be happy to make that! And maybe you could part the completed deep file?

Would be happy to help out. I had it working in the past but unfortunately lost that data when I grenaded my Motherboard :(

Are you saying that the exact same firmware on the 5i25 and the same wiring to the 7i76 works with LinuxCNC and does not work with PathPilot?

That is, indeed, very strange.

Can you check that hm2_5i25.0.sserial-port.0.run = 1?
(I guessed the pin name, it's something like that)

Hi
Sorry you haven't heard from me I've been looking at your configs and found the issue
in your hal config you have this line
setp hm2_5i25.0.gpio.010.invert_output 1

GPIO 10 is used by the smart serial interface as seen in the dmesg output.
[581661.810026] hm2/hm2_5i25.0: 34 I/O Pins used:

[581661.810051] hm2/hm2_5i25.0:     IO Pin 016 (P3-13): IOPort

and in your hal file its noted has
# P3 pin 7 gpio 010
# Z step
setp hm2_5i25.0.gpio.010.invert_output 1

so the stepgen is trying to control this pin as is the SS interface

i loaded your config up on my PP machine and had the same issue you do.
I commented out the setp hm2_5i25.0.gpio.010.invert_output 1 and everything started working (though my wiring is different than yours it did respond to all my inputs)

screen shot shows 7i76 input 02 going active




comment out that line in yours and I expect you'll get working.

I had thought it would be either the watchdog or something like this after we ruled out the hardware.
also while it is work, it's best to configure PP hal file completely to help eliminate issues like this.

quick edit to clean up a few thing
btw: if you want halshow working i and another user posted on how to get it working. but as I recall source was needed but i can provide missing files.

Holy crap! Trying this right now. Will report back shortly.

EDIT: It worked! I have limit switches!!!!!

Now I just have two wiring shorts to deal with, my Z axis only moves upwards (pretty sure thats a ground fault issue) and one of my limits is dead. Awesome!!!! Thanks so much!!!

Got the limit switch sorted, now trying to work on the Z axis. Because pin 10 is used for communication between the 6i25 and the 7i76 I assume this means I have to use a different pin on the 7i76 for the Z axis invert signal, as its now correctly being used for sserial comms?
