I did a little fiddling and reduced the wobble:
It's around half a millimetre but it still needs improving. The problem is caused by the connection between the motor shaft and the studding shaft, which is slightly off-center. That's because I'm using plastic tubing to connect the two and the weight of the X axis assembly distorts the plastic tubing. It holds the distorted shape to some degree so it wobbles.
The X axis wobble is essentially completely gone now and that was the worst before, so this is a good step. It needs some more work. I may be able to re-inforce the tubing so it doesn't distort.
