I2C Send failed #31311 (CORE One) #35311 (CORE One L) #2631…

What happened?

On your Prusa Printer, the I2C bus is used for the xBuddy and Buddy boards to communicate with other printer components. If there is an error in sending data from the xBuddy board, the printer will show the message: "HAL detected an I2C error when sending data via I2C."

Error name: I2C Send failed

Error code: #31311 (CORE One) #35311 (CORE One L) #26311 (MK4S) #13311 (MK4) #27311 (MK3.9S) #21311 (MK3.9) #28311 (MK3.5S) #23311 (MK3.5) #12311 (MINI/+)

How to fix it?

Restarting the printer is expected to resolve the error, and this is not expected to occur again. In case a restart does not resolve it, please contact our customer support, and we will take it from here.

This has happened twice on my new Mk4 , it freshly built and i have only run 8 small prints on it. So far that's 25% of the time . Should I be worried about this? Any body else seeing this ?Team Prusa , any cause for this I behaviour that is should look out for ?

Happened to me twice in about a dozen prints. Restart fixes it, but the error came back, contrary to the "How to Fix It" instructions that indicate the error should not occur again.
