Gather Parts: 4x- 500mm Aluminum Extrusion, M5 threaded one end 4x- 510mm Aluminum Extrusion, ends not threaded 41x- M5 T-Nut 32x- M5x10 BHCS 32x- M5 Washer, Black 8x- Corner gussets

Gather Tools: 3mm Hex driver Squaring fixture

Install four (4) T-Nuts into one side of a 500mm aluminum strut (tapped on one end), position the T-Nuts so there are two (2) at each end of the strut; repeat for a second 500mm strut (tapped on one end).

Install four (4) T-Nuts into one side of a 510mm aluminum strut, position the T-Nuts so there are two (2) at each end of the strut.install five (5) T-Nuts on the second 510mm strut.

Place the four (4) struts with the T-Nut side up

Arrange each of the 500mm struts parallel to each other and with their threaded ends at the same end oriented toward yourself

Place each of the 510mm struts between the 500mm struts so the 510mm struts align with the side and end of the 500mm strut (T-Nut sides should still be up)

Insert two (2) T-Nuts into the inside slot of the bottom 510mm strut. Use two (2) M5X10 BHCS to install two y chassis mounts, these will be used later in the assembly.

Insert two (2) T-Nuts into the top side slot of the top 510mm strut, these will be used later in the assembly

Place a corner gusset at each of the strut intersections; Loosely secure each gusset with (4) M5X10 BHCS and (4) M5 black washer.

Place one corner joint into a known square location, such as a squaring table; ensure the corners are square and the ends are flush; Secure each of the gusset screws are tightened to 40 in-lbs; repeat this for each corner.

Now you're ready for z axis final assembly.
