You have a few things going on here. Let’s dissect them.

You’re correct you don’t need a U2C. I would recommend removing it from the CANbus.

Am I right in assuming this all started after updating klipper?

When you run the MAKE FLASH command are you getting the DFU error at the end of the process?

Since your UUIDs are already assigned klipper will report back 0 UUIDs.

Yes, 2. Yes. and also I keep getting the mcu error with klipper 'disconnected' on the monitor screen.

#

I get moonwalker : connected / Klipper: disconnected

There was a breaking update to klipper. The troubleshooting channel had a few threads that should get you back up and running.

hmmm if you are talkin about the cfg files? I think I have the latest for manta v2

No. I’m talking klipper. Check the troubleshooting channel. You will find many threads with similar problems to yours.

Ok, new problem now. Klipper is still getting shut down. I get angry red error box now, that says virtual sd card, pause resume and something else is a problem....

#

Most likely you need to add [mainsail.cfg] to your printer.cfg.

#

https://docs.mainsail.xyz/setup/configuration

Configuration

Mainsail requires a minimum configuration to function properly and will display a warning at startup if the required parts are not found in your configuration file(s).
