Trouble with the z nut lock. Assembly guide says:

Put the z nut lock on smaller end towards the stepper.

Tighten up the Z nut lock with a screw driver and needle nosed pliers. The screw closest to the stepper motor does all the holding.

First, is it weird that, with the nut lock arranged as described, it’s friction that holds the z assembly from falling towards the table? I mean, I guess that’s cool, because the rest of the parts on the system are clamp-fit, too.

But the problem is that I can’t tighten up the Z nut lock enough to grab the coupler nut — the gap in the plastic is closed, but the coupler happily slips through. Did I miss a step?
