Do: Slide eight M5 T-nuts into the E extrusion: per end, two in the top slot and two in the bottom slot. None in the side slots. Push them 10–15 mm from the ends, under the drive frame's bolt holes.
Check
4 nuts at each end: 2 top, 2 bottom, threaded holes facing outward, none jammed.
What you're looking at
The E extrusion is the XY bridge: the beam across the back of the gantry that holds the two drive blocks a fixed distance apart and so sets the gantry's width. The eight M5 T-nuts are what those blocks bolt down onto.
