20 years ago I tried Linux CNC once, but I gave up due to language barriers and the European purchase restrictions of the cards.
I have built quite a few CNC machines in the past 40 years in systems running under Win.
Today's language translation programs can be an incredible help.
Clone cards are now available at a reasonable price, so I thought I would try the Linux world again.
The helpfulness that the Linux forum provides is amazing.
A special shout out to PCW for his help and expertise that he shares.
I am an electrical engineer and I can create an electrical circuit diagram in minutes. My limitations when it comes to PC programming are huge. I have been trying Linux for 2 weeks. I still have a lot of questions. Today I will upload the unique configuration I received from PCW to the 7I92 card.

I'm civil/builder/construction labourer, using the page I linked to I was able to create Mesa bitfiles (then some custom ones for a clone board I made).

What it comes down to is being able to follow instructions.

Hi
I installed the received **.bit file on the card from the command line.
When I read it back from the card, everything is fine.
How can I insert the custom config into Pncconf?

The easiest way is to use pncconfs  "Discovery" option

You need to select "Show Advanced Option Pages"
on the first pncconf page for the discovery option
to be available.

Pncconf found the card, read the settings and they are displayed.
I chose a lathe X-Z axis for the test.
I configured the X-Z spindle PWM and the Charge pump encoder end positions etc...
It doesn't let me proceed, it says no axis or PWM is configured.
What did you do wrong?
A few pictures of the settings.

You have 1 active PWM generator but no pin out for it chosen, so either set the PWM number to 0 or select a pin for spindle PWM
