Error running LinuxCNC after setting up with Pncconf was created by mloser

I have a computer with a 6i25 Mesa board installed as 5i25. I have the 7i76_7i77 setup. 7i76 and 7i77 both have power and LED's are lit. After finishing up in Pncconf, I try to run LinuxCNC and it fails with an error message. I'm new to LinuxCNC, so I'm guessing I'm missing something or doing something wrong.

Thanks,
Mike

Both Mesa 7i76 and 7i77 require Field power besides the 5V logic supply, they have dedicated connectors for that, see the manual, and require 8-24V for the field inputs and outputs to work.
You can edit the config files and omit the I/O pins if you just need to check connectivity and functionality as the logic side works with 5V only, so steppers on 7i76 should work, encoders on 7i77 also should work.
