[we didn't use the ultimaker for 8 months]

It's Windows and we already tried Cura 13.11 with the printer turned on and also another computer. We probably have to update the printer but there is no connection.

 

[we didn't use the ultimaker for 8 months]

Because of an renovation we didn't use the Ultimaker for 8 months and now we want to start it up again but the computer which whe always used doesn't recognized the printer. There is no connection with Cura 12.08. Do you have a suggestion?
