Medium 2 day(s) false en PP_Extruder_Pro_PXL_20211203_182039160.jpg none ==== 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 <br/> ==== Steps ==== # Slide 6 t nuts into the top side of the 1000mm extrusion. (repeat for other beam) # For the 300mm beams, 2 pairs of 2 will be identical, one "I" shaped, and one "C" shaped. # 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. # For the I-Beams, repeat the same steps for the C-beam, but on both sides. # Repeat so you have 2 I-beams and 2-C beams. # *Optional* Add bolts to all remaining bracket holes and loosely attach t-nuts. (as seen in the right two beams in image 3) ====Tools==== 1/2" Socket Wrench ====Parts==== Assemblies from previous step ====Steps==== #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. #Repeat for the bottom rail. #Secure the C beams in place with the socket wrench, but leave the I-beams LOOSE as they will need to be shifted later. ==== Tools ==== 1/2" Socket Wrench ==== Parts ==== Assembly from previous step 4x Steel Corner Brackets 32x M8x20 Bolts 32x M8 washers 32x t-nuts ==== Steps ==== # On the exterior corner of the 4080 extrusion, slide 3 t-nuts into each top/bottom rail. # Secure corner plate to rale with accompanying 6 bolt/washer combos. # 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. # Repeat on all corners. ====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==== #Slot 2 t-nuts into one rail of the 300mm extrusion #Secure corner brackets on the rail, ensuring that the ends are flush with the beam. #Slide a t-nut into a rail on the 800mm extrusion about 12in from the end. #Secure one side of the short beam to the long beam. #Repeat on the other side. #Repeat steps 1-5 so you have 2 "H" assemblies. ====Tools==== 1/2" Socket Wrench ====Parts==== 2 "H" Assemblies from previous step Top deck Assembly ====Steps==== #Shift the top deck assembly off your worksurface so that 2 corners are free hanging in space. #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. #Slide the H assembly up until it is flush with the top deck and holding its weight. #Once in place, tighten down the bolts #Repeat on the other side. ====Tools==== 1/2" tap ====Parts==== Table assembly ====Steps==== #Tap the two central holes on the exterior of the 1000mm 4080 extrusion. #Repeat on all 4 corners. ====Tools==== 1/2" socket wrench ====Parts==== Barrel Support Assembly Table Barrel 4x M8x20 Bolts 4x M8 washers ==== Steps ==== # Place the Barrel support assembly on the table so it that it crosses the two "I" assemblies. # Loosely attach the assembly to the table with bolts/washers. # Place the barrel into the support structure, aligning the flat notches on the barrel to the bracket. # Slide the barrel towards the end of the table until the threads CLEAR the table face. # Leave these connections loose as it will be moved into its final position later. # Temporarily remove the barrel. ==== Tools ==== 1/2" Socket Wrench adjustable wrench ==== Parts ==== Barrel Extrusion Screw 3x Bearings 1x Bearing spacer Flange Bearing Housing 8x M8x25 Bolts 8x M8 washers 8x M8 nuts ==== Steps ==== # Slide the bearings onto the screw shaft, followed by the bearing spacer. # Slide the barrel over the screw. # Slide the bearing housing over the bearings and flush with the barrel. # Slide the flange over the shaft and flush with the bearing housing. # Secure the bearing and flange in place with m8 bolts/washers/nuts. # (see image 5 for a finished state, but ignore the other parts) ==== Tools ==== Mallet Hex wrench (for heating element bolts, depends on manufacturer) ==== Parts ==== 20mm coupling 1/4" Key(filed down) 6x heating band elements ==== Steps ==== # Place the key into the keyway on the extruder shaft. # 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. <br/> # On the other end of the barrel, slide the heating elements into position. ## Three should be within the barrel supports, and three should be past the support towards the extrusion end. ==== Tools ==== 1/2" Socket Wrench Adjustable wrench ==== Parts ==== Gearbox support A Gearbox support B Gearbox/motor assembly 8x m8x25 bolts 8x m8 washers 8x m8 nylon lock nuts ==== Steps ==== It is important to note that the two supports are not identical. Support A has a narrower base than B. # Position the supports as seen in Image 1, ensuring that support A faces the gearbox side with longer distance between its wall and the shaft. # Secure the supports with bolts/washer/lock nuts. ==== Tools ==== Mallet ==== Parts ==== 1 1/8" Shaft 1/4" key 1 1/8" coupling Gearbox ==== Steps ==== # Place the key into the shaft # Slide these parts into the gearbox until flush with the back side of the gearbox. # Slide the coupling onto the shaft ==== Tools ==== 1/2" socket wrench ==== Parts ==== Motor Assembly Table 4x m8x20 Bolts 4x washers Spider coupling ==== Steps ==== # Position the motor on the table, sliding the t-nuts from the previous steps into position. # Loosely secure the motor to the table. # Insert the spider into one of the couplings. # Making use of the loose bolts, move the barrel and motor together until they are meshed at the couplings with the spider in between. ====Tools==== 1/2" socket Metal break Digital angle gauge ====Parts==== Perforated shield 6x M8x16 bolts/washers ====Steps==== #Identify the small cut notches on the sheet metal that indicate where the bends should go. #Using the break, fix the sheet metal in position (figure 2) and bend the sheet at a 45 degree angle. #Flip and repeat for all 4 bends. #Position the shield in place and secure the back row with 4 bolts/washers and the pre-installed t-nuts. #attach the front of the shield with only the left two bolts. (the other two will be utilized for securing the electronic box later) ==== Tools ==== Metal break Digital angle gauge or square edge vice Rivet gun or hex wrench set ==== Parts ==== 2x pre-cut hopper sheets 6x rivets or M4 nut/bolt combo ==== Steps ==== # Using the break, fold the perforated sheet on the designated lines to 90 degrees. Both bends should be inward, so that the triangle flap and short flap face each other. # The bottom of the hopper sheets need to be flared out so it can fit around the barrel. *We found this easier to do in the vice because you can visually inspect the angle # Place the bent hopper half in a vice, and slowly press on the rectangular face until the top of sheet is parallel with the floor/table. (image 3) # Repeat for the other sheet. # Nest the two pieces so the triangular face is captured by the lip on the other sheet. Secure in place with either bolts/nuts or rivets # Place the hopper over the barrel. ====Tools==== 13mm tap (or 1/2") 1/2" socket wrench 3/4" socket wrench ====Parts==== 2x 300mm Extrusion 2x Steel barrel brackets 4x corner brackets 4x 13mm hex bolts (or 1/2") 4x 13mm washers 4x M8x20 Bolts 4x M8 washers 4x t-nuts ====Steps==== #Tap both end holes in each 300mm beam. #(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) #Slide 2 nuts into each beam. position these rails on the outside/facing away from each other (see image 6 for orientation) #Secure the barrel brackets to the beams as seen in image 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.
