I have been struggling for a few days now with trying to resolve this error and I suppose I don’t really know where to start. After a bunch of searching and reading posts I haven’t been able to narrow down what causes this.
It typically happens about an hour into a print. I get this message after shutdown:
“MCU ‘mcu’ shutdown: Scheduled digital out event will exceed max_duration”
I have attached the log file of the most recent event. I have tried to dissect the log file myself and the only thing I’ve found that looks out of place is the error for my bme280 temp sensor that I am using for my heated chamber. Although I think I would see an i2c timeout error if this were the reason for shutdown.
This error only happens during a print. I have left the Pi and my board sitting powered and idle overnight without faults.
The following is my setup:
BTT Octopus 1.1
Raspberry Pi 3B+
The BME 280 sensor is connected directly to the Octopus board through i2c.
The Raspberry Pi is connected to the MCU by USB
If I am leaving any important information out I apologize. I usually try to wait until I have exhausted all my options and gone as far as my research can take me. Hopefully someone here can point me in the right direction.
Thanks!
