Hello @moreirae !

Your system is quite unstable:

| throttle_state: '0xD0000'
Under-voltage has occurred, Throttling has occurred, Soft temperature limit has occurred

| throttle_state: '0x50000'
Under-voltage has occurred, Throttling has occurred,

| throttle_state: '0x80008'
Soft temperature limit active, Soft temperature limit has occurred

You may take care for a better power supply and a better cooling for the Raspberry Pi.

A side note: The serial logging is not enabled.

Good afternon Ewald,
Where I can enable the serial logging?
What is maximun temperature ? I have ear is about 85 degrees Celsius!!! When I am near to the PC I have look and is around 55!

When you click the word logs, there is a description where to find it:

serial.log : A log of all of the communication going on between OctoPrint and your printer. Usually disabled for performance reasons, enable it through Settings > Serial Connection.

Godd morning Ewald,
you know some plugin who record the temperatures and voltage from the Pi?
Can ypu explain me where you see the errors ?

These errors are documented in the octoprint.log every time you restart OctoPrint.

More to the throttle_state is here:

The lower, the better.
Mine are running in idle without active cooling at about 53°C. When running with fan it's about 43 °C. During works it's not more than 55°C.

Thanks for your attention
