The cube screws won't come out or in

Hi,

I have tried to unscrew the orange cube from base, but only one screw came out the other 3 are now stuck in a mid position and won’t go out or in !

Any advice ? Should I send it for servicing ?

Please send it to your local dealer for servicing.

From my experience, Cube needs to be in a perfectly horizontal position in order to get the screws to thread in properly.
