New to klipper and trying to get the set up correct.
running mainsail on a raspberry pi printed a single layer bridging test, the way it turned out confused me if perhaps there is a flow issue?
If I may give my 50c: It shows, that you did not properly follow the setup instruction of klipper because if you would have done so, it would look different
But to give you any better tip where to start: How does a ringing test look like at your actual setup?
