4. X-Gantry Assembly

Attach the V-Slot-2040-750mm to the back two holes on the Y-Plate-Right-Assembly using 2 x M5-Low-Profile-15mm bolts.

Attach the C-Beam-750mm to the four non-threaded holes on the Y-Plate-Right Assembly shown above using 4 x M5-Low-Profile-15mm bolts.

Before the Y-Plate-Left-Assembly can be attached, Tee-Nuts need to be inserted.

The Tee-Nuts should be inserted so that the flat face is facing outwards.

Insert 2 x Tee-Nuts in to the front facing top slot, 2 x Tee-Nuts in to the front facing bottom slot.

Slide the X-Carriage-Assembly onto the C-Beam-750mm in the orientation seen above.

Repeat Step 1 for the Y-Plate-Left-Assembly.

Recheck the bottom Eccentric-Spacer-6mms on the X-Carriage-Assembly to make sure they are touching the rail, there is no wobble, and that the X-Carriage-Assembly runs smoothly along the whole length of the C-Beam-750mm.

Place the X-Gantry Assembly onto a flat table. Check both Y-Plates are sitting flush with the table. Loosen the extrusions and adjust if needed.

Looking at the Y-Plate-Left, adjust the X-ACME-Screw so the end is on the extrusion side of the Y-Plate-Left.

In the gap between the Y-Plate-Left and Flexible-Coupler, insert a 688zz-Bearing, 8mm-Shim, and 8mm-Clamping-Collar. With the 688zz-Bearing closest to the Y-Plate-Left, seated inside the recess.

Adjust the X-ACME-Screw back through the 688zz-Bearing, 8mm-Shim, and 8mm-Clamping-Collar, until it touches the NEMA 23-Stepper-Motor shaft.

While pushing the 8mm-Clamping-Collar against the 8mm-Shim and 688zz-Bearing into the recess on the Y-Plate-Left, tighten the clamping bolt on the 8mm-Clamping-Collar.

Tighten the grub screws on the Flexible-Coupler. Make sure one is on the flat portion of the motor shaft.

On the outside of the Y-Plate-Right slide on a 688zz-Bearing, 8mm-Shim, and 8mm-Clamping-Collar. Inset the 688zz-Bearing into the recess.

While pushing the 8mm-Clamping-Collar against the 8mm-Shim and 688zz-Bearing into the recess on the Y-Plate-Right, tighten the clamping bolt on the 8mm-Clamping-Collar.

Attach an Angle-Corner to the Y-Plate-Right-Assembly & the front facing top slot of the C-Beam-750mm. A M5-Low-Profile-8mm screws into the Tee-Nut previously inserted, and a M5-Low-Profile-15mm goes though the Angle-Corner and attaches to a M5-Nyloc-Nut on the outside of the Y-Plate-Right-Assembly.

Repeat this for the other 3 Angle-Corners in the positions shown above.
