6. Y-Gantry Assembly

Position the two Extrusion-F's on top of the Base-Assembly.

Carefully slide the Y-Carriages on the X-Gantry through the Extrusion-F's

Adjust the position of each Extrusion-F so the ends are flush with the corners of the Base-Assembly.

Prepare 2 x Y-End-Plate in the orientation shown in Image 1, with a M5-Button-Head-Bolt-12mm through each of the 4 bottom holes and a M5-Tee-Nut slightly threaded onto each one.

The flat side of the M5-Tee-Nut should be facing the Y-End-Plate.

Repeat the above 2 points, but for 2 x Y-End-Plate in the orientation shown Image 2.

At the front right corner of the machine, slide a Y-End-Plate into the two front-facing slots of Extrusion-A.

Attach the Y-End-Plate to Extrusion-F using 4 x M5-Button-Head-Bolt-16mm through the non-threaded holes on the Y-End-Plate and into the threaded holes on Extrusion-F.

Make sure the side of the Y-End-Plate is flush with the end of Extrusion-A.

Then tighten all the M5-Button-Head-Bolt-12mm on the Y-End-Plate.

Repeat for the other 3 corners of the machine.

Slide the X-Gantry to the back of the machine as far as it will go.

Slightly loosen the 4 x M5-Button-Head-Bolt-12mm on each of the two front Y-End-Plates.

Carefully slide the X-Gantry to the front of the machine as far as it will go.

Re-tighten the M5-Button-Head-Bolt-12mm loosened in the green point above.

Keep the machine at the front and slightly loosen the 4 x M5-Button-Head-Bolt-12mm on each of the two back Y-End-Plates.

Carefully slide the X-Gantry to the back of the machine as far as it will go.

Re-tighten the M5-Button-Head-Bolt-12mm loosened in the orange point above.

Insert a Lead-Screw-Y through the large 16mm hole on the front right Y-End-Plate so it protrudes into the channel on Extrusion-F roughly 100mm.

Slide onto Lead-Screw-Y a Flanged-Radial-Bearing - ->- - Rubber-Bushing - ->- - Clamping-Collar.

Insert the Lead-Screw-Y further into the channel, and then thread it through both Nut-Blocks on the Y-Carriage-Right.

Once through the Nut-Blocks, slide onto Lead-Screw-Y a Clamping-Collar - ->- - Rubber-Bushing - ->- - Flanged-Radial-Bearing.

Thread through Lead-Screw-Y further so it goes through the large 16mm hole on the back right Y-End-Plate. Adjust the Lead-Screw so there is 14mm protruding from the back right Y-End-Plate.

Seat the Flanged-Radial-Bearings into the Y-End-Plates, slide the Rubber-Bushing against the Flanged-Radial-Bearings and finally slide the Clamping-Collars so they are against against the Rubber-Bushings. Slightly tighten the Clamping-Collars.

Repeat all the above points for the left Y-End-Plates and Y-Carriage-Left

On the Lead-Screw-Y protruding from the front right Y-End-Plate, slide on a Nylon-Shoulder-Washer - ->- - Thrust-Bearing-Housing-Washer - ->- - Thrust-Bearing-Caged-Roller - ->- - Thrust-Bearing-Shaft-Washer

The Nylon-Shoulder-Washer seats in the 16mm hole on the Y-End-Plate.

The Thrust-Bearing-Caged-Roller seats in the grooves on the Thrust-Bearing washers. Same orientation as before.

Finally slide on a Clamping Collar. While pushing the Clamping-Collar against the Thrust-Bearing assembly, tighten the Clamping-Collar.

Repeat all the above for the front left Y-End-Plate.

On the Lead-Screw-Y protruding from the back right Y-End-Plate slide on a Nylon-Shoulder-Washer - ->- - Thrust-Bearing-Housing-Washer - ->- - Thrust-Bearing-Caged-Roller - ->- - Thrust-Bearing-Shaft-Washer

The Nylon-Shoulder-Washer seats in the 16mm hole on the Y-End-Plate.

The Thrust-Bearing-Caged-Roller seats in the grooves on the Thrust-Bearing washers. Same orientation as before.

Finally slide on a Flexible-Coupler. While pushing the Flexible-Coupler against the Thrust-Bearing assembly, tighten Flexible-Coupler

Repeat all the above for the back left Y-End-Plate.

At the front right corner of the machine, an Angle-Corner goes in the corner between Extrusion-A and Extrusion-F.

First slide an M5-Tee-Nut into the top slot of Extrusion-A.

Use a M5-Button-Head-Bolt-8mm and the previously inserted M5-Tee-Nut to attach it to Extrusion-A.

To attach it to Extrusion-F, use a M5-Button-Head-Bolt-8mm and M5-Drop-In-Tee-Nut.

M5-Drop-In-Tee-Nuts do not need to slide in from the end.

They go in to the slot parallel, when the bolt engages they should spin perpendicular to the slot and bite into the underside of the slot.

Repeat the previous step for the other 3 corners.

Attach a Stepper-Motor to the threaded holes on the back left Y-End-Plate using 4 x M5-Cap-Head-Bolt-50mm and 4 x Aluminium-Spacer-40mms.

Once in position, tighten the clamping bolt first, then the grub screw.

Repeat the previous step for the right Y-Axis Stepper-Motor.

Attach an End-Cap to the front left end of Extrusion-A using 2 x M5-Button-Head-Bolt-8mm.

Repeat this for the other 3 bare ends of the Extrusion-A's.
