Gather Materials

2 Remove LGX Filament Guide and Rotate Motor

Remove the two screws on the bottom side of the LGX extruder [PP-MP0335].

Then set the direct drive end to the side.

Remove the bottom two screws on the LGX extruder body
Once the screws are removed, take the direct drive part and set it to the side

3 Install the Heat Break and Hot Block

Place the hot block [PP-MP0337] inside the hot block jig, making sure the flat side is on the bottom.

Then thread the heat break [PP-MP0339] into the hot block and tighten with a 9mm wrench.

Once the heat break is secured to the hot block place the four post (part of the hot block hardware kit [HD-MS0100]) in the four corner holes in the hot block.

Now align the four corner posts and the heat break with the ACE cold block [PP-MP0341], make sure the side of the hot block that has the through holes is on the opposite side of the cold block.

Now using the torque wrench secure the hot block to the cold block using the screws from the hot block hardware kit.

Once the hot block is secured to the cold block thread the Mirco Swiss 1.75 nozzle [PP-MP0412] into the hot block then use the nozzle torque wrench to tighten the nozzle.

Then align the cold block with the LGX extruder and replace the two bottom screws that held the direct drive piece.

Place the hot block inside the hot block jig
Hand thread the heat break into the hot block
Tighten using a 9mm wrench
Place the four corner posts from the hot block hardware kit
Align the hot block and cold block then slide the heat break and corner posts into the cold block
Make sure the through holes on the hot block are on the other side of the cold block
Using the torque driver and the screws from the hardware kit secure the hot block to the cold block
Then thread the Micro Swiss nozzle into the hot block
Use the nozzle torque wrench to tighten the nozzle
Align the cold block with the LGX extruder
Using the same bottom bolts from the direct drive, secure the cold block

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.

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 - 175mm [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.

6 Install the Fan Duct

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]

7 Place Caution Hot Sticker

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

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
