Hello everyone
My Ender 3V2 has been running Klipper for a year now. And without any problems. Well, from one day to the next the PI can no longer connect to the board.
I did all the updates, re-flashed the firmware from the board, tried other cables, other USB ports on the PI. Without success! I found various posts in the forum, unfortunately without success.
The Ender 3V2 is running with BTT SKR Mini E3 V3
Any ideas?
When I run ls /dev/, the “serial” is displayed, so there is a connection to the board.
ls /dev/serial/by-id/
returns no such file or directory found.
