Étape 1 - Table Build-Top deck 1

Tools

1/2" Socket

Parts

2x 1000mm 4080 extrusion

4x 300mm 4040 extrusion

40x t-nuts

22x M8x20 bolts

22x M8 Washers

12x Corner Brackets

Steps

1. Slide 6 t nuts into the top side of the 1000mm extrusion. (repeat for other beam)
2. For the 300mm beams, 2 pairs of 2 will be identical, one "I" shaped, and one "C" shaped.
3. For the C-shaped beam, Slide two t-nuts into one rail. Attach the corner brackets at the ends, ensuring the bracket is flush with the beams end. *Always use the side of the bracket with a flat face (non-lipped) first. This ensures you can get a tool onto the 2nd bolt without being blocked.
4. For the I-Beams, repeat the same steps for the C-beam, but on both sides.
5. Repeat so you have 2 I-beams and 2-C beams.
6. *Optional* Add bolts to all remaining bracket holes and loosely attach t-nuts. (as seen in the right two beams in image 3)

Étape 2 - Table Build- Top deck 2

Tools

1/2" Socket Wrench

Parts

Assemblies from previous step

Steps

1. If you have already attached the bolts/and t-nuts from the optional step - Slide beams into the upper channel (as seen in image 1) Otherwise, thread the nuts into the channel and attach LOOSELY with bolts.
2. Repeat for the bottom rail.
3. Secure the C beams in place with the socket wrench, but leave the I-beams LOOSE as they will need to be shifted later.

Étape 3 - Table Build- Top deck 3

Tools

1/2" Socket Wrench

Parts

Assembly from previous step

4x Steel Corner Brackets

32x M8x20 Bolts

32x M8 washers

32x t-nuts

Steps

1. On the exterior corner of the 4080 extrusion, slide 3 t-nuts into each top/bottom rail.
2. Secure corner plate to rale with accompanying 6 bolt/washer combos.
3. Add 2 additional bolt/washer/t-nut combos to the 2 remaining vertical holes. Keep these very loose as we'll slide them into another assembly later.
4. Repeat on all corners.

Étape 4 - Table Build - Side Legs 1

Tools

1/2" Socket Wrench

Parts

4x 800mm 4040 Aluminum extrusion

2x 300mm 4040 Aluminum extrusion

4x corner Brackets

8x M8x20 Bolts

8x M8 washers

8x t-nuts

Steps

1. Slot 2 t-nuts into one rail of the 300mm extrusion
2. Secure corner brackets on the rail, ensuring that the ends are flush with the beam.
3. Slide a t-nut into a rail on the 800mm extrusion about 12in from the end.
4. Secure one side of the short beam to the long beam.
5. Repeat on the other side.
6. Repeat steps 1-5 so you have 2 "H" assemblies.

Étape 5 - Table Build - Side Legs 2

Tools

1/2" Socket Wrench

Parts

2 "H" Assemblies from previous step

Top deck Assembly

Steps

1. Shift the top deck assembly off your worksurface so that 2 corners are free hanging in space.
2. Position an H assembly underneath the corners, aligning the pre-attached t-nuts to the external rail slots. This requires you to adjust the t-nuts so they are perfectly vertical.
3. Slide the H assembly up until it is flush with the top deck and holding its weight.
4. Once in place, tighten down the bolts
5. Repeat on the other side.

Étape 6 - Table Build - Tapping beams

Tools

1/2" tap

Parts

Table assembly

Steps

1. Tap the two central holes on the exterior of the 1000mm 4080 extrusion.
2. Repeat on all 4 corners.

Étape 7 - Barrel Support 1

Tools

1/2" tap

1/2" socket wrench

3/4" socket wrench

Parts

2x 300mm Extrusion

2x Steel barrel brackets

4x corner brackets

4x 1/2"x1" hex bolts

4x 1/2" washers

4x M8x20 Bolts

4x M8 washers

4x t-nuts

Steps

1. Tap both end holes in each 300mm beam.
2. (check to make sure the 1/2 bolts fit through the large holes on the barrel brackets. If not, use a 1/2" drill bit to open the holes up)
3. Slide 2 nuts into each beam. position these rails on the outside/facing away from each other (see image 6 for orientation)
4. Secure the barrel brackets to the beams as seen in image 5.
5. Secure corner brackets to slotted t-nuts so the open hole is facing down. Keep these loose as there final position will be determined later.

Étape 8 - Barrel Support 2

Tools

1/2" socket wrench

Parts

Barrel Support Assembly

Table

Barrel

4x M8x20 Bolts

4x M8 washers

Steps

1. Place the Barrel support assembly on the table so it that it crosses the two "I" assemblies.
2. Loosely attach the assembly to the table with bolts/washers.
3. Place the barrel into the support structure, aligning the flat notches on the barrel to the bracket.
4. Slide the barrel towards the end of the table until the threads CLEAR the table face.
5. Leave these connections loose as it will be moved into its final position later.
6. Temporarily remove the barrel.

8x M8 washers

8x M8 nuts

Steps

1. Slide the bearings onto the screw shaft, followed by the bearing spacer.
2. Slide the barrel over the screw.
3. Slide the bearing housing over the bearings and flush with the barrel.

1/4" Key(filed down)

6x heating band elements

Steps

1. Place the key into the keyway on the extruder shaft.
2. Slide the coupling over the shaft/key until it is flush with the extruder shaft. It should not come into contact with the m8 Bolts on the flange.
   
3. On the other end of the barrel, slide the heating elements into position.
   1. Three should be within the barrel supports, and three should be past the support towards the extrusion end.
