Hey everyone, my dryer keeps periodically disconnecting with this error:
MCU ‘mcu’ shutdown: I2C START READ NACK
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown
It can work fine for 2–3 hours, or it can crash after 10 minutes) Any idea where to look?

Всем привет, периодически отваливается сушилка с такой ошибкой:
MCU ‘mcu’ shutdown: I2C START READ NACK
Once the underlying issue is corrected, use the
“FIRMWARE_RESTART” command to reset the firmware, reload the
config, and restart the host software.
Printer is shutdown
Может работать нормально по 2-3 часа, а может свалиться через 10 минут) Куда копать?

Check the soldering on the temperature and humidity sensor
