17. Installation of the Upper x-Profile

(1) 5.0x100mm Hexagon Ballpoint Screwdriver

(2) 6.0x125mm Hexagon Ballpoint Screwdriver

(3) Electronic Super Knips

(4) Soft-faced Hammer with Cellidor Head Sections

(5) Caliper 300mm

(6) Stop Angle

(1) 8x M6x12mm Hexagon Socket Head Cap Screws

(2) 9x T-Nuts

(3) 2x M8x40mm Hexagon Socket Head Cap Screws

(4) 2x End Caps

(5) 2x Corner Brackets

(6) 2x z-Top Mount, left and right

(7) x-Aluminium Extrusion

Insert 2x M6x12mm Hexagon Socket Head Cap Screws into a corner bracket.

Screw them loosely to the corner bracket using 2x T-Nuts.

Pay attention to the alignment of the T-Nuts (Fig. 3).

Repeat this step for the other corner bracket.

Place 2x M6x12mm Hexagon Socket Head Cap Screws in one of the z-top mounts.

Screw them loosely to the z-mounts with 2x T-Nuts.

Pay attention to the alignment of the T-Nuts (Fig. 3)

Repeat this step for the other z-top mount.

Slide one of the corner brackets into the right slot of the left z-extrusion so that the end of the extrusion and the corner bracket are level.

Now tighten the M6x12mm Hexagon Socket Head Cap Screws in the corner bracket on the Z-axis.

Repeat this step on the right side.

Push the x-extrusion through the two T-Nuts.

Make sure that the large holes in the x-extrusion are pointing up and the small holes are pointing down.

Loosen the 2x M6x12mm Hexagon Socket Head Cap Screws in the corner brackets on the z-axis.

Insert 2x M8x40mm Hexagon Socket Head Cap Screws into the x-axis and tighten them hand-tight.

Then press the two corner brackets against the x-axis and retighten the 2x M6x12mm Hexagon Socket Head Cap Screws.

Remove the 2x M8x40mm Hexagon Socket Head Cap Screws from the x-axis.

The x-axis should now be movable to the right and left.

Move the x-axis to the right.

Slide the left z-top mount into the front slot of the left z-axis using the lower T-Nut.

Carefully position the left hole in the z-top mount over the z-rod.

Gently tap the z-top mount with a hammer so that it is at the same height as the z-axis.

Slide the x-axis over the T-Nut and make sure that the Nut and the T-Nut are at the same level.

Now, tighten only the lower M6x12mm Hexagon Socket Head Cap Screw.

Repeat these two steps for the right z-top mount.

Place a T-Nut in the upper slot of the x-axis.

Now, prepare the 2x End Caps by shortening the center part by half (e.g. using a side cutter).

Be careful not to cut off too much or the end caps will not hold on the axis.

Finally, attach both end caps to the ends of the x-axis.

Use a stop angle to ensure that the x- and z-axes are at a 90° angle to each other.

Tighten the M6x12mm Hexagon Socket Head Cap Screw in the corner bracket on the x-axis.

Tighten the M8x40mm Hexagon Socket Head Cap Screw in the x-axis.

Repeat this step on the other side.

Then re-check to make sure that the x- and z-axes are at a 90° angle to each other.

If this is not the case, you have to align the x-axis again.

Once you have successfully aligned your x-axis, use a caliper to measure the distance between the two z-axes.

To do this, place the caliper at the corner brackets.

The distance between the two z-axes must range between 304.90 - 305.50mm.

The measured value between the two z-axes and those of the xy-frame, must not exceed a difference of 0.05mm.

If the difference of their values is > 0.05mm, you have to re-align the frame (see Step 11).

If the difference of their values is < 0.05mm, insert and tighten the 2x M8x40mm Hexagon Socket Head Cap Screws into the x-axis.

If necessary, tighten these two screws with a torque wrench set to 2.5NM.

To check this, measure the distance between the z-axes again. If these values are < 0.05mm, continue with Step 13. Otherwise, you have to loosen the 2x M8x40mm Hexagon Socket Head Cap Screws again and re-align the x-axis (see Step 11).

Lastly, tighten the top M6x12mm Hexagon Socket Head Cap Screws on the left and right z-top mounts.

The installation of the upper x-profile is completed now.
