I just figured out what the gpio pins are and they are if iam correct the 50 pins on P1 and P2 halshow was not showig any sserial port pins. That is probably why the pin do not exist errors I was getting is from.
Just a thought

When you say you have an error,
Please please copy/paste that error
in your post.

It's nearly impossible to diagnose the issue
without accurate error reporting.

Also do you have a red LED (CR11) illuminated
above the Spindle connection (TB4) ?

Before you start LinuxCNC, does red LED CR11 (above TB4) Illuminate?

OK that means you have no VIN so the field I/O section is unpowered

Normally VIN comes from VFIELD (W1 LEFT)

So either you have:

1. No VFIELD

2. W1 is in the right hand position (it should be in the default left position)

3. Some hardware issue with the field I/O section.
