Not able to get outputs on GPIO of Raspberry5

Not able to get outputs on GPIO of Raspberry5 was created by AndyCNC
Hi,
I'm a bit desperate. I want to replace my very old pc based linuxcnc with the actual version running on a raspberry pi 5.
I've been trying to get signals to the pin header for a day now.
First of all: Is there a tutorial for raspberry configuration? I found nothing except the general docu and then went from one error message to another.
What I did is:
1. Started Stepconf wizard
2. Replaced parallel port Pins with hal_gpioxxx, see attached hal file
When I start this Setup following error occurs:
This was my try to set the PINs:
Would be nice if onyone could show my where I'm wrong.

Note: Using POSIX realtime
The GPIO line PIN3 can not be found

Have you run the "gpioinfo" command? That will list the available pins. If it doesn't work that may mean that you don't have gpiod installed.
Is your user account a member of the "dialout" group?

Thanks for your fast reply.
That's the output of "gpioinfo", looks ok for me:
And group "dialout" seems to fit also:

Index to major thread, there's a section regarding your query with an example for a simple 3 axis machine that works.

Link to manpage
linuxcnc.org/docs/devel/html/drivers/hal_gpio.html
First hint is here:
The GPIO line PIN3 can not be found.
PIN3 isn't a name of a pin, pins are named as per man page.

Thanks. When I use the naming in the linked config instead of the naming from docu it works!
I can see dir and step signals now on the correct pins.
One last problem before I can test with the machine. I use an enable signal for the stepper driver. I see it on the pin, but inverted. Is there a possibility to invert output pins at raspberry pi 5 or should I better do it in hardware?
