It seems like the motors are getting power.
When I run a g code file, the gantry appears to work, until you realise that it never moves to the right.
Seems to have lost its marbles?

Can anyone tell me if there is someone in the UK I can call and pay to have this thing checked out?

Thanks.
Now then, the motors that move the torch will likely be working off STEP (how many increments) and DIRECTION (L or R) signals, it looks like the latter isn't working - could be as simple as a bad connection, shouldn't be too difficult to diagnose. Have you done some Googling? a quick search pulled up this page:

which seems to be something to do wit Blade Runner machines, there's something about support and a user forum by the looks.
