Materials needed

2 Hot Block Assembly

2A) Remove the copper part and spring from PP-MP0340 and screw into PP-MP0351 then place in the red jig block.

2B) Grab the torque wrench with a 9mm socket on the end. Double check that it is set at 3.98 NM.

2C) Torque the heat break into the hot block. Be sure to have the socket all the way down on the hot block when torqueing.

2D) Grab 4 posts from HD-MS0601 and insert them into the hot block.

2E) Grab AS-CB0208 and remove the braiding from the wires. Make sure that none of the wires are twisted up.

2F) Grab a #1 screw from HD-MS0601 and secure the ground wire in the spot shown. Be careful when tightening the screw. The wire should be close to the post but not against it and the hole close to the heat break needs to remain clear.

2G) Insert the heater cartridges into the spots shown and secure using #1 screw from HD-MS0601. Check to make sure the protective casing on the wires did not get pinched under the screw.

2H) Grab 1x EL-TH0012 and insert it where shown and secure using #1 screw from HD-MS0601.

2I) Can put the previously removed spring and copper part back onto the heat break now.

2J) Grab two #2 screws and two washers from HD-MS0601. The washers go on the screw with the convex side towards the screw head. Screw with Washer |--(----

2K) Grab 1x PP-MP0350 and line it up with the four posts and heat break and push them together. Take the two #2 screws and washer and insert them into the shown holes.

2L) Secure the hot block to the heat sink by torquing the #2 screws. Double check to make sure the screws were tightened all the way.

2M) Install one #1 screw from HD-MS0601 on the thermistor side of the nozzle side of the hot block.

2N) Place 1x HD-MS0105 on the end of the heat break.

3 Motor Assembly

3A) Grab PP-MP0336 and remove the 2 screws from the LGX block and remove the LGX block. Save the screws but, the LGX block will not be used again.

3B) Using the 2 screws from the LGX block install the Hot Block Assembly onto PP-MP0336.

3C) Grab 1x PP-MP0501 and install it in PP-MP0351 using the nozzle torque tool.

3D) Grab 1x PP-GP0731, 2x HD-BT0039, and 2x HD-WA0038.

3E) Install PP-GP0731 on the shown side of PP-MP0336 using 2x HD-BT0039 and 2x HD-WA0038.

3F) Take the square fan from AS-CB0208 and run the wires through the channel in PP-GP0731. Make sure the wires get all the way into the channel.

3G) Install the square fan onto PP-MP0350 using 2x HD-BT0005.

3H) Run the blower fan wire to be in between the motor and the rest of the wires.

3I) Plug the motor wires into the motor.

3J) Grab 1x PP-GP0732, 3x HD-BT0137, and 3x HD-WA0038.

3K) Attach PP-GP0732 to PP-GP0731 using 1x HD-BT0137 and 1x HD-WA0038.

3L) Finish attaching PP-GP0732 using 2x HD-BT0137 and 2x HD-WA0038 into PP-MP0336.

3M) Insert the blower fan into PP-GP0732 and attach using 1x HD-BT0171 and 1x HD-WA0038.

4 Finishing Steps

4A) Stick 1x DC-LB0154 sticker onto the blower fan where shown.

4B) Reattach the braiding onto the wires having the thermistor wires sticking out the side.

4C) Use 2x HD-MS0588 to secure the braiding on the wires. Be sure to have the thermistor wire sticking out in between the two zip ties. Plug the thermistor into the wires.

4D) Stick 1x DC-LB0160 onto the connector of AS-CB0208 and 1x DC-LB0160 onto PP-MP0336 where shown.

4E) Install PP-MP0353 onto PP-MP0351.

5 Tool Head Testing

5A) Plug the tool head into the #1 test plug and the thermistor jumper into the #2 test plug.

5B) Turn on the test printer and push the knob in.

5C) Scroll down and select “Print From SD”

5D) Select “Aero-Style-x1.gcode”

Note:
Only one Asteroid tool head can be tested at a time.

The square fan should always be on while the printer is on. After selecting a print the blower fan should kick in briefly and the tool head should start to heat up. Once the tool head heats up the motor will cycle. After that the blower fan will turn on to cool down the tool head. .
