well I tried 22 to 28 ad 24 to 28 with the same output. I would post it but the form says its spam.

Sorry . But I formatted it to put the new image when I got the new pi working . I thought that I had some time and could do the same flash as the new card and pi and it’s crazy it worked . I did use the pi lite image this time compared to the one that was shipped with the board. Maybe that was it ?

so the problem was the image > I redid the pi3 with a fresh image also and the pins worked. but I'm running the pi 4 on my duet 3!

New pi came in today and I reloaded a fresh image and the issue is resolved ! Thank you for your help !

yeah crazy it's not working. the sd card is the one from the duet 3 box I got last week. my duet 3 is working in standalone mode for the moment. this pi had a gpio header touch screen the image before I used it as a duet pi. the question is do I wait till Tuesday with the new PI 4 and just try the sd card in it or do I flash a new complete fresh start on it?

sorry I had to snip it because it gets flagged as spam if I put it in as code. jumpers installed on 19-21 and 22-24 . pi is on my desk with nothing attached.

here is the output .
