Do: Cut the chain to length. Slide the T-nut into the top slot of the X extrusion. Fix the chain's fixed end to it with one M3×6 FHCS, and the moving end to the CW2 chain anchor with two.
Check
Push the toolhead through its full X travel by hand. The chain rolls, never drags on the extrusion, and never reaches full extension.
What you're looking at
A drag chain is an articulated conduit letting a cable follow a moving part without flexing in the same spot twice. The X chain runs along the top of the X extrusion, fixed at one end, clipped to the toolhead anchor at the other.
Caution
Rev D+ / LDO: the kit ships 2-hole chain ends — print *_2hole variants, never *_3hole. src
