You didn't say in your first post that you had replaced the fuse several times otherwise I would had said something different.
If a fuse blows once sometimes it's bad luck, but twice indicates a problem and as others have said the last thing is to increase the fuse size. As Clive says try it with the motor disconnected. You could swap the motor from another drive, or swap the board with another board, the trouble there is you might end up with two faulty boards.
If you bought it in the UK you could probably send it back to the suppplier for testing.
