My Ultimaker 3 is connected by WIFI to my Laptop with Cura. After about 20 min printing UM3 disconnects from Cura. Means webcam image freezes and UM3 can't be controlled any more. I can reconnect to UM3 in "manage printers" but any time I need to walk to UM3 to allow the connection by button pressing. Is there a way that the connection stays longer? Is there a way to connect without manual confirmation at UM3?
