    That comes later (the lead screws) during the Z-axis commissioning. Yes, that picture is annoying in that it shows a completed assembly. In fact you will first make the bed slide nicely before putting in the screws (there is a video). Remember lithium grease on the rods!

    I know that it is important to grease the action, but do the bearings have dust protectors on them, as these will push the grease to the travel limits and collect there? If so, I would pack the bearings with lithium grease before sliding onto the rods, then just a light wipe of grease on the rods to protect them. This is the technique I used on my current printer with success.

    Yes they do (or at least the spares I ordered have dust wipers) So I think you are right..the best time to add the grease is during assembly, with persistence you can get it in there through repeatedly adding it to the rods and running the bearings backwards and forwards but most of it will be pushed to the end of the axis rather than go into the bearing as you say.

    I smeared it down the rod carefully with a dust-free wipe, into a nice film, then took the blob off the ends after running back and forth a few times...
