Hello smart people,

I can't wrap my head around this problem:

Printer: V0
Controller: Fysetc Cheetah V3.0
No CAN

I have been printing with my V0, 400 print hours.
Can connect to mainsail dashboard,
everything works normally (heaters, steppers and fans),but shuts down after printing for approximately 30 min. Gives ''lost communication with MCU'' after firmware restart works normally again. But when it is printing again it will shut down with the same error.
there is no reliable connection with the controller board 😦

Nothing changed in config files
checked the wiring
(faulty usb C?)
(fried board?)
I will post a picture of the wiring diagram

I have a spare octopus V1, but no stepper drivers for it
