Hermit Crab, power, changing tools, and Klipper MCU shutdown?

Hey everyone,

I have a BIQU Hermit Crab CAN tool changer which works like a charm. Only problem I’m having is that every time I either shut off the PSU or change a tool, Klipper shuts down because either the connection to the Hermit MCU gets lost (yeah, no power…) or the thermistor reports rubbish (yeah, no thermistor…). I would like to maybe somehow detect these states/events and keep Klipper from shutting down. Do you think there’s a way to achieve that?


Might be helpful

Ah that’s cool! Looks promising. I’ll check it out tomorrow, thank you very much!
