2 Install the Internal Frame Corners

Take the front frame and align the T-slot nuts with the corner of the frame.

Using 1x 90 degree corner bracket [HD-EX0090], 2x M5 x 10 BHCS [HD-BT0073] and 2x M5 washers [HD-WA0040] attach the corner bracket to the corner of the frame.

Repeat the process for the other three corners on the front frame.

Then using the torque driver, torque all the screws securing the corner bracket.

Repeat the process for the rear frame.

Start with the front frame
Align the T-slot nut then fasten the corner bracket to the frame
Make sure the screws are secured at the outside end of the slots
Repeat for the other three corners
Torque each corner bracket
Repeat process for the rear frame
Rear frame done

3 Assemble the Front Frame

Place the front frame sub-assembly on the table with the black corner brackets resting on the table.

Then use 1x M5x10 BHCS SST [HD-BT0225] to secure the aluminum corner bracket to the top most T-slot nut on the right extrusion.

Then use 1x M5x14 SHCS [HD-BT0049] with a M5 washer [HD-WA0040] to attach the dual spool arm to the left extrusion. Be sure to use the dual spool arm spacer to set the distance from the bottom of the front frame and the flat side of the spool arm. Make sure there is one T-slot nut above the spool arm and two below it.

Rotate the front frame so that it's resting on the bottom extrusion.

Then take 1x M5x12 BHCS [HD-BT0158] and slide a 5M washer [HD-WA0040] around it followed by a thumbscrew leash [PP-GP0448].

Now follow [reference#1] and use the bolt, washer and thumbscrew leash to secure the bed mount chassis [PP-GP0432] to the inside of the bottom extrusion.

Repeat for the second bed mount chassis, make sure the thumbscrew leashes are points towards the outside of the frame.

Install the aluminum corner bracket to the top most T-slot nut on the right extrusion
Use the spool arm spacer to secure the dual spool arm, make sure to the flat side of the spool arm
Place a washer and thumbscrew leash around HD-BT0158
[reference#1] Install the left bed mount chassis to the top side of the bottom extrusion
Repeat for the right bed mount chassis
Front frame assembled

4 Assemble the Rear Frame

Place the rear frame on the table with the black corner brackets facing up.

Then use 1x M5x14 SHCS [HD-BT0049] with a M5 washer [HD-WA0040] to attach the tippy feed tube holder to the left extrusion.

Now flip the rear frame over so that its resting on the black corner brackets.

Install the tippy feed tube holder
Install the electronics chassis mount
Install the dust cover on the left extrusion
Slide the dust cover over the wire
Install the dust cover on the top extrusion
Make sure the wire harness looks like this

5 Attach X End Left and X End Right

Place the rear frame on the table with the black corner brackets resting on the table.

Take the X end right assembly and identify where the tabs for the extrusions are along with the slot for the wires before attaching it to the rear frame.

Now align the tab with the extrusion and slide it into the extrusion, make sure you are using the top right side of the rear frame and that you route the wires through the slot.

Then using 2x M5x10 HHCS [HD-BT0250] attach the bottom of the X end right assembly to the rear frame.

Repeat for the X end left assembly using the top left side of the rear frame.

Slide the front frame extrusions into the tabs on the right and left X ends.

Then carefully flip the whole assembly over and use 4x M5x10 HHCS [HD-BT0250] to secure the front frame to the right and left X ends.

Now turn the assembly so that the top is facing you.

Use 8x M5x10 BHCS [HD-BT0073] with M5 washers [HD-WA0040] to secure right and left X ends to the front and rear frame assemblies.

Carefully align the wires and extrusion is the X end right
Secure the bottom side of the X end right
Repeat process for the right side
Carefully slide the front frame extrusions into the left and right X ends
Flip the whole assembly over so that the rear frame is on the top
Secure the bottom sides of the left and right X ends to the front frame
Secure the top side of the X end left to the front and rear frame
Repeat for the top side of the X end right

6 Loosen the Frame Bolts

Before using the frame squaring fixture loosen the following bolts:

  • The 8 bolts on the top of the frame
  • The 4 bolts for the Z lower left
  • The 4 bolts for the Z lower right

You only have to loosen them by half a turn, this will let the printer naturally settle inside the frame squaring fixture.

Loosen the frame bolts

7 Square and Torque the Frame

Place the frame inside the frame squaring fixture, then secure the four clamps.

Now use the following tools to tighten the bolts:

  • Torque Gun
  • Ratchet Wrench
  • Wrench

Use these tools to tighten the following bolts:

  • The 8 bolts on the top of the printer
  • The 4 bolts for the Z lower left Do not over tighten, or part could break!
  • The 4 bolts for the Z lower right Do not over tighten, or part could break!

Once the 16 bolts have been tightened, unclamp the frame from the frame squaring fixture.

Place the printer inside the frame squaring fixture
Pull down on the clamp handle to secure the clamp
Repeat for the other clamps
Secure the top bolts with the torque gun
Secure the top bolts with the torque gun
Tighten the Z lower left with the ratchet wrench
Tighten the Z lower left with the wrench
Tighten the Z lower right with the wrench
Tighten the Z lower left with the ratchet wrench
Tighten the Z lower right with the wrench ratchet
Unclamp the frame from the frame squaring fixture

8 Install the Frame Feet

Install the 4x frame feet [PP-GP0409] to the frame using 4x M5x10 [HD-BT0073] with M5 washers [HD-BT0040].

Make sure to place a M5 washer inside the flexy foot
Install the flexy foot to the bottom of the frame
Repeat for the other three flexy feet

9 Connect the Limit Switches

Connect the right and left Z max wires to the limit switches on the top right and left sides of the frame.

Connect the right Z Max wires
Connect the left Z Max wires
