There's a big step- the Z axis is fully(ish) assembled! At least all the hard parts (ie, the ballscrew is secured and going through the carriage). I made a small mistake, and need to drill a hole up top so I can tighten the coupling onto the leadscrew, but that's not terribly difficult nor requiring precision. There leadscrew also isn't quite centered in the axis, so I need to machine out the mounting holes for the stepper plate a bit so it can float into the right position. Again, no big deal.
Overall I'm happy. The plate to attach it to the X axis is "done"- all the holes are cut, the relevant surfaces machined flat, and the cutout for the leadscrew mounting block has been made. All that needs to be done on it is to cut it down to the right size- it currently has an extra ~inch on one side...
