2 Remove Heat Sink and Rotate Motor

Take the LGX extruder [PP-MP0336] and remove the two screws that are holding the heat sink to the extruder body.

Set the two screws and heat sink a side as these will be used in a later step.

Now remove the top right screw that is holding the motor in place. Once the screw is removed rotate the motor 180 degrees so that the motor wire connector is on the bottom side of the assembly.

Then secure the motor using the top right screw.

Remove the two screws that hold the heat sink to the extruder body
Remove the heat sink
Unscrew the top right bolt that holds the motor in place
Then rotate the motor so that the connector is on the bottom then tighten the top right screw

3 Install the Extruder and Hotend

Take the hot block [PP-MP0338] and place the flat side on the table, make sure "Slice Engineering" is right side up.

Then hand thread the dark grey part from the heat break [PP-MP0340] into the hot block. Now tighten with a 9mm wrench.

Now take the hot block hardware kit [HD-MS0100] and follow [reference#1] to assemble the heat break and hot block assembly.

Using the four cylindrical posts, slide one into each corner of the hot block.

Now slide the silver washer over the heat break followed by the spring, then slide the heat break cap over the heat break.

Once the heat break is attached to the hot block, align the four posts with the four holes on the bottom side of the ACE cold block [PP-MP0342] then slide the heat break and hot block assembly into the ACE cold block. Make sure the thermistor and heat cartridge holes are on the opposite side of the cold block!

Now place the filament guide collar around the top of the heat break.

Then use the torque tool and the two small screw from the hot block hardware kit [HD-MS0100] to secure the hot block to the ACE cold block. Torque these screw to 0.12 Nm.

Hand thread the micro swiss nozzle [PP-MP0416] into the hot block, then tighten using the nozzle torque wrench.

Then align the ACE cold block with the extruder body [PP-MP0336] and secure the ACE cold block to the extruder body.

Thread the heat break into the hot block then use a 9mm wrench to tighten
[reference#1] Assemble the heat break
Slide the heat break and hot block assembly into the ACE cold block
Make sure the slide of the hot block that has the holes is on the other side of the ACE cold block
Slide the heat break collar around the hot of the heat break
Using the torque tool secure the heat block to the heat sink
Hand thread the micro swiss nozzle into the hot block
Then use the nozzle torque wrench to tighten the nozzle
Place the heat sink over the extruder body
Secure the heat sink to the extruder body

4 Install Meteor Wire Harness

Find the motor wire that's a part of the Meteor wire harness [AS-CB0209] and connect it to the extruder motor.

Then slide the heat cartridge and thermistor wires into the hot block, make sure its on the back side of the extruder assembly. (Motor on the left side)

Use one of the silver SHCS from the hot block hardware kit [HD-MS0100] to secure the heat cartridge and thermistor wires to the hot block.

Now flip the extruder assembly over so that the front is facing up and secure the ground wire to the front side of the hot block using the other silver SHCS from the hot block hardware kit.

Connect the motor wire to the motor connector
Slide the heat cartridge wire through the bottom hole in the back side of the hot block
Slide the thermistor wire through the top hole on the backside of the hot block
Secure the wires using 1x silver SHCS [HD-MS0100]
Secure the ground wire to the front side of the hot block using 1x silver SHCS [HD-MS0100]

5 Install the Extruder Mount

Remove the top right screw from the backside of the motor. Set the screw off to the side as it will not be needed for the final assembly.

Take the Meteor mount - 285mm [PP-GP0725] and slide the case fan wires through the bottom channel in the Meteor mount.

Then attach the Meteor mount to the backside of the extruder assembly using 1x M3x30 SHCS [HD-BT0187] with M3 washer [HD-WA0038] to attach the Meteor mount to the motor and 1x M3x12 SHCS [HD-BT0039] with a M3 washer [HD-WA0038] for the backside of the Meteor mount.

Now attach the case fan to the ACE cold block using 2x M3x10 SHCS [HD-BT0005], make sure the wires are at the end of the case fan wire channel in the Meteor mount.

Remove the top right screw from the back of the motor
Slide the case fan wires through the channel
Use 1x M3x30 SHCS [HD-BT0187]** w/ M3 washer to secure the side of the Meteor mount to the motor
Use 1x M3x12 SHCS [HD-BT0039] w/ M3 washer to secure the back of the Meteor mount
Attach the case fan to the ACE cold block using 2x M3x10 SHCS [HD-BT0005]

6 Install the Blower Shroud

Align the Meteor fan duct [PP-GP0726] with the extruder body and Meteor mount.

Then use 3x M3x8 BHCS [HD-BT0137] with M3 washers [HD-WA0038] to secure the fan duct to the Meteor mount as well as the extruder body.

Once the Meteor fan duct is attached align the blower fan, from the Meteor wire harness, with the Meteor fan duct and secure using 1x M3x20 BHCS [HD-BT0171] with a M3 washer [HD-WA0038]

Align the Meteor fan duct with the extruder body
Use 2x M3x8 BHCS [HD-BT0137] w/ M3 washers to attach the front of the Meteor fan duct to the extruder body
Secure the side of the fan duct to the Meteor mount using 1x M3x8 BHCS [HD-BT0137] w/ M3 washers
Align the blower fan with the fan duct and secure using 1x M3x20 BHCS [HD-BT0171] w/ M3 washer

7 Place Caution Hot Sticker

Place the caution hot sticker on the front side of the blower fan in the bottom left corner.

Place the caution hot sticker on the blower fan

8 Secure the Wire Braid to the Wire Harness

Using 2x 4" cable ties [HD-MS0588], secure the top and bottom ends of the wire braid to the Meteor wire harness.

WARNING: Make sure the thermistor connector is only secured by the top cable tie and pulled out of the wire braid before the bottom cable tie

Place a cable tie at the top and bottom ends of the wire braid, make sure the thermistor connector is pulled out of the wire braid before the bottom cable tie
Make sure the thermistor connector is out of the wire braid before tightening and trimming the bottom cable tie
