This video covers the assembly of the Z Axis Lead Screw, including the anti-backlash nut. This step can be a bit confusing for first time builders. I tried to break it down to make it as easy as possible:

1) First position all your m3 nuts and ensure that your lead screw is centered;
2) Loosen everything and install the anti-backlash nut, and tighten everything down.
3) Check that there is no binding.

If you feel any binding (where it is harder to turn the lead screw in some spots) you will need to make adjustments. At this point in the build, as long as your bed was moving OK before installing the lead screw, it may be that your lead screw is not perfectly centered between the extrusions. You may want to measure the distance from the screw to the extrusion on both sides and make adjustments. Raise the bed so that it is in the center of the printer to check the distance. Adjust the bottom screws as needed to get centered properly.

In the worst case, you may have a bent lead screw. A bent lead screw can be straightened with a bench vise, but that is beyond the scope of this video (please ask in Voron_0_qustions discord if you have this issue). It may be easier to request a replacement motor/lead screw if you run into this issue.

Powder Coated Extrusions are from DLLPDF. These extrusions, at the time of the video are Mitsumi. They are powder coated and exactly 15mm x 15mm (the coating adds a small amount of thickness). I purchased a full v0.2 extrusion kit.
