Well, all the electronics arrived, with a few bonuses thrown in (highly recommend Homann Designs if you're an Aussie). I didn't get a chance to throw it together unfortunately.
The major drama this break was that I managed to build the X-Axis drive plate and connect it. The ball screw got slightly bent in transit (the center moves by 1mm up and down when rotated), but I thought I'd get away with it. Unfortunately when I drove it with a hand drill, it ran, but the whole machine shakes if I run it too fast. I'll have to replace it I think.
