@CSteveP

i am not using CAN at this stage

I appears you put a lot of macros into your printer.cfg just by random choice.

[mcu pitb]
canbus_uuid = 0a754ef78da4

...

[mcu sb2040]
canbus_uuid = 62aff65e7dcf

Please start with a simple printer config

Regardless of the software / system / whatever: My simple experience:

• KISS → Only install things that you understand what they are doing. Start with a minimum configuration and get this running
• Extend your config one at a time. Again, only with things that you understand what they are doing and that you actually need
• If things start going wrong, then you need to debug only one addition or simply return to your known good base config
• This advice holds especially true for the millions of Klipper macros floating around: You virtually need none of them to get a working printer. And if, you should understand what they are doing and why you need them.

(This is a free-of-charge, completely selfish advice to keep my own sanity: Many users go exactly the other way round)
