Hello, after updating Klipper was unable to connect to the MCU.
(It was working fine before updating)
I reinstalled Klipper and the problem stayed or is even worse:
I have tried some solutions in this forum but nothing helped.
I hope someone can help me with this.
Thank you,I have tried the solution now.
But it didnt work for me.
Seems like im affected with the bug of version “247.3-7+deb11u2”.
I added the source and installed it after fixing the Error with the public signing keys.
Make sure you followed the instructions to the letter. In doubt, re-check / repeat.
Post the output of
apt-cache policy udev
Okay i have repeated the process.
The output of
apt-cache policy udev
looks like this:
udev:
Installed: 252.5-2~bpo11+1
Candidate: 252.5-2~bpo11+1
Version table:
*** 252.5-2~bpo11+1 100

100 /var/lib/dpkg/status
247.3-7+rpi1+deb11u2 500
500 Index of /raspbian bullseye/main armhf Packages
Unfortunately following command still fails
My problem is now solved.
I have followed a couple post.
Seems like https://klipper.discourse.group/t/ender-3-s1-no-usb-id/8120/5?u=rbk
fixed my issue.
But im not very sure
