Describe your issue:

Hi all,
I turned on my voron 2.4 for the first time in 6 weeks. I was able to log in through mainsail and Moonraker right off the bat no problems. I completed an update
next thing I know its telling me it is unable to connect to my MCU. I tried through Tera term using
KIAUH to get my MCU ID, with no luck. It says no MCU found.
Any help would be greatly appreciated. Thanks in advance!

Also for future reference, it’s best not to update without a specific reason. Random things can break like this upstream Debian bug, and it can cause a lot of downtime trying to fix it.

Thank you. I’ll try this evening.
