Hi,
I would like to say great software! Thanks to everyone involved.
I just have a small issue. I have Klipper running on my Pi3, and I can use Putty to log in. Fluidd works perfectly, and I can log in there with no issues. However, I’m having trouble setting up the printer.cfg file.
When I try to ls /dev/serial/by-id/, it says “ls: cannot access '/dev/serial/by-id/’: No such file or directory.”
When I run sudo dmesg, I get this information, so I know the USB is working:

How do I update the printer.cfg with this information?

Thank you!
