Do not shutdown when secondary mcu is not connected

I would like to have a feature to disable klipper shutdown when secondary mcu is not connected. I think it will be usefull in cases when one uses such things as portable input shaper. Now I need to: connect input shaper mcu with USB → add include file for it’s config → restart klipper → do shaper calibraion → save config → remove include for mcu config → restart klipper → disconnect input shaper from USB.
If there would be a way to make secondary mcu optional the process chain is much more simplified: connect input shaper mcu with USB → do shaper calibraion → save config → disconnect input shaper from USB.

Hi, did you find any solution? It would be usefull for me too

Hi, the only solution is to move mcu configuration to a separate file and use [include] in printer cfg when that mcu needed.
