What happened?
Our printers have an extensive list of errors, to categorize them and help find a cause and solution.
In rare cases, an error can occur that is not in our list of errors. In that case, the printer shows the message "This error code is not found in our database. Contact the support".
Error name: Unknown error
Error code: #31601 (CORE One) #26601 (MK4S) #13601 (MK4) #27601 (MK3.9S) #21601 (MK3.9) #28601 (MK3.5S) #23601 (MK3.5) #17601 (XL) #12601 (MINI)
How to fix it?
Ensure you are using the correct up-to-date firmware for both the printer and the MMU unit: Firmware download.
If that does not solve the error, take note of all the actions that preceded the error happening. Try to reproduce the error, and save the log.
After that, contact our Support client, or report the issue directly in the Prusa GitHub page.
