Ender 3 S1 Pro
HW in stock, rPI gen 4 connected
I am trying to install Klipper on my printer. I have installed MainsailOS, flashed the printer with generated firmware. I have uploaded printer.cfg file, but MainsailOS seems to be not able to communicate with printer.
Mainsail shows following info - restart or firmware restart makes nothing.
After a few minutes the warning changes to error:
I have googled this error and it seems to me like I have to configure somehow my connection on rPI side…
Can anyone advice me how to do that?
I have followed this guide and set the “menuconfig” items as screenshot, but there is no mention in the guide what USB port should be used (expected it doesnt matter…)?

Can anyone advice how to move forward and diagnose/fix my problem to make klipper work?
Thank you.
