That looks very familiar… Are you passing the movement test?
If not, take the black cable, find a good film sit on the cable for the length of the film.
Once the film has finished, bend the living daylights out of the black cable. Wind it round a pencil or a wooden spoon.
Once you have done this, re-attach to the machine. If the cable passes the movement test, i highly recommend marking the socket at each end and only mark it on one side of the connector. Although you can put these connectors in both ways (unlike normal USB) this will aid quick connection.
One final thing. The oil bottle whilst small is important to use on all moving parts. The ball joints all typically have a foam insert. Squeeze out about 4mm in length and distribute with the nozzle. Then once the ball joints are back, twist the rods they should turn freely after a few turns.
The white tube needs a bit of stretching too. But dont bend as it will kink and not maintain a smooth curve.
