What happened?

On the Original Prusa MK4S/MK4/MK3.9/MK3.5, the I2C bus is used for the xBuddy board to communicate with other printer components. All communication is expected to occur within a timeframe: if this does not happen while data is being sent from the xBuddy board, the printer will show the message: "HAL detected an I2C timeout when sending data via I2C."

Error name: I2C Send Timeout

Error code: #26313 (MK4S) #13313 (MK4) #21313 (MK3.9) #23313 (MK3.5)

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, we will take it from here.
