It looks like you’re running an old version of Klipper in “usb to canbus bridge mode” that is known to have problems ( Upgrade if using Klipper USB to CANbus bridge mode ). You should definitely update, as we know there were issues with older versions of the code.
If the issue does reoccur after updating, I really need the logs from a pristine version of Klipper in order to investigate. Issues like this are very hard to track down, and they’re basically impossible if I don’t have the exact code that is running.
