7i76e with 7i85S to control 9 steppers

I decided to try a multi-prong approach to the homing:

linuxcnc only fails on the input-00 and not on the gpio.015.in lines. What am I doing wrong?

First I would delete any gpio related lines in the hal file since they are not appropriate
for your use

if the field I/O pins (hm2_7i76e.0.7i76.0.0.xxxxx) are not found that means there an issue with the field I/O

For field I/O to work you need:

8 to 24VDC on TB1 (+8 to 24 on pin 1 = bottom Gnd on pin
This must be present on linuxCNC startup

W1 left

W8 left

My field power pins were correct. However, I checked the jumper pins as you suggested and noticed that W8 was to the right, in "SETUP" mode. The 7i76e manual explains that it changes the baud rate of the communication, but it doesn't explain any other difference between SETUP or OPERATE mode. I had no idea that it would deactivate the homing pins. I figured I was still trying to get things set up, so I should be in SETUP mode.

Actually the manual does state:

"W8 must be in the "operate" mode for normal operation."

I just wish it explained the difference between "normal operation" and "setup" a little more clearly. I feel like with just a few test pieces and a jumble of wires laid out on my desk I'm far from "normal operation."

Anyway, thanks for all of your help. I've got the first homing switch working (still gonna test all . My next test will be to control the digital outs with M62/M63 commands.

Soon we're going to tackle the problem of running linuxcnc over the network. If we can lick that problem then we'll be ready to update the robot to the new system. I'm definitely looking forward to that!

Maybe the Mesa manuals should call "Setup" "Card Firmware Flashing Mode" instead?
