Install the drive gear [PP-MP0282] onto the motor [EL-MT0069] using the printed drive gear spacer jig as shown. Apply Blue Loctite and torque the set screw to 3 in*lbs.
A set screw should come pre-installed in the gear, if not, ensure an M3x3 set screw is used. Set screws of any greater length will interfere with the larger gear during operation.
Thickness of the printed spacer is 5mm
Install one sealed MR95ZZ bearing [HD-MS0446] into the extruder body [PP-MP0204] as shown.
Install the internal lock washer [HD-WA0027] as shown.
Using one M3 x 12 BHCS [HD-BT0146], fasten the extruder body [PP-MP0204] to the motor through the printed mount [PP-GP0341].
To verify the correct nozzle size is being used check to make sure there are no dot marking around the nozzle.
0 markings = 0.25mm
1 marking = 0.30mm
2 markings = 0.35mm
3 markings = 0.40mm
6 markings = 0.50mm
4 markings = 0.60mm
5 markings = 0.80mm
Install the bearing [HD-MS0446] into the heatsink [AS-HE0043] as shown.
Install the large drive gear [PP-FP0154]. Make sure the faces of the two gears are flush with each other. Adjust the pinion gear as necessary. If adjustments are required, make sure to re-torque the pinon gear set screw.
Install the idler [PP-FP0135] and the idler spring assembly [HD-NT0011], [HD-MS0430], & [HD-BT0197].
Install the filament guide path [PP-FP0136] as shown.
Install the heatsink assembly [AS-HE0043] onto the Extruder Body as shown.
Route the heater cartridge wires and the thermistor wires as shown.
Put the zero sense line [AS-CB0063] onto one of the M3x35 SHCS [HD-BT0043], then put it into the lower right mounting hole as shown.
Lift the zero sense line fastener out part way and slide the blower shroud [PP-GP0342] over the hotend.
Put in the other two M3x35 SHCS [HD-BT0043] into the top two mounting holes, and put the M3x30 SHCS [HD-BT0042] into the lower left mounting hole.
Make sure not to pinch the zero sense line.
Torque the fasteners to 3 in * lbs in the sequence shown in the photo.
Route the Hotend Ground wire as pictured.
Using one M3 x 20 BHCS [HD-BT0171] with a washer [HD-WA0038], install the blower fan [AS-CB0062] as shown.
Route the wires around back by the motor connector.
Apply 1x- 0.5mm "Hot" Warning Sticker [DC-LB0185] to the part cooling fan, exactly as pictured.
Using four M3x12 SHCS [HD-BT0039] install heatsink fan [AS-CB0064] as shown.
Be sure the fan is in the correct orientation. The label should not be visible and the screws should sit flush in the fan housing.
Connect motor harness [AS-CB0061] and thermistor extension harness [AS-CB0066] as pictured
Pin all harnesses to the connector according to the diagram, excluding the hot end ground wire until the next step.
While pinning the hotend ground wire last, wrap around the bundle of wires once or twice as pictured before pinning.
Obtain one Idler Tube Clamp Right [PP-GP0428]
Snap the Idler Tube Clamp into place on the Idler Lever.
Place a piece of filament through the Idler Tube Clamp and the Idler Lever to ensure proper alignment of the filament pathway.
Secure the Idler Tube Clamp to the Idler lever using one M3x8 SHCS [HD-BT0157].
Tighten securely.
Thread another M3x8 SHCS [HD-BT0157] into the top hole of the Idler Tube Clamp Right [PP-GP0428]
Do not tighten
Open one end of the 3/8" self-wrapping braided sleeving [EL-WR0158] and slide it around the tool head wires.
Then slide the braided sleeving around the rest of the wires and position it in the middle of the wires.
Install 2x 8" wire ties [HD-MS0058] at both end of the braided sleeving then tighten and trim.
After assembly of the TAZ AeroStruder is complete, it is necessary to verify the electrical properties of the toolhead, namely the heater cartridge and thermistor.
Refer to the pin-out diagram above for pin locations
First we will test the resistance value of the heater cartridge;
To do so, first set your multimeter to Ohms which is signified by the capital Greek letter Omega.
Now touch the probes of your multimeter to pins 3 & 13 individually.
Note: Positive or negative probe positions are irrelevant to this test.
The display on the multimeter should now show a value around 19 Ohms.
Any value between 12.8 and 14.4 Ohms is acceptable, values outside of that range are cause for rejection of the heater cartridge and it should be replaced.
Next we will verify that the heater cartridge DOES NOT have continuity to the ground circuit.
To do so, the multimeter may remain in Ohms mode or be switched to an audible continuity test mode by moving the switch to the symbol representing sound waves.
Now touch one probe to the heater block, and the other to pins 3 and then 13, individually.
Note: Positive or negative probe positions are irrelevant to this test.
Whether probing pin 3 or 13, the multimeter display should remain at 0 and no audible alarm should sound.
This indicates that there is no continuity between either lead of the heater cartridge and the toolheads ground circuit.
If the multimeter display reads anything but 0, or an audible alarm is heard during either half of this test, the heater cartridge must be rejected and replaced.
Next we will perform the same tests for the thermistor.
To do so, first set your multimeter to Ohms which is signified by the capital Greek letter Omega.
Now touch the probes of your multimeter to pins 9 & 19 individually.
Note: Positive or negative probe positions are irrelevant to this test.
The display on the multimeter should now show a value between 80 and 120 K Ohms.
Pay close attention to the units displayed on the multimeter's display; the letter 'K' should be displayed to the right of the value.
If a reading is given in Ohms or Mega Ohms (indicated by the letter 'M' to the right of the value displayed) or the kOhms reading is too low (values displayed as 1.xx or similar) or otherwise outside of the range stated above, the thermistor must be rejected and replaced.
Next we will verify that the thermistor DOES NOT have continuity to the ground circuit.
To do so, the multimeter may remain in Ohms mode or be switched to an audible continuity test mode by moving the switch to the symbol representing sound waves.
Now touch one probe to the heater block, and the other to pins 9 and then 19, individually.
Note: Positive or negative probe positions are irrelevant to this test.
Whether probing pin 9 or 19, the multimeter display should remain at 0 and no audible alarm should sound.
This indicates that there is no continuity between either lead of the thermistor and the toolhead's ground circuit.
If the multimeter display reads anything but 0, or an audible alarm is heard during either half of this test, the thermistor must be rejected and replaced.
To finalize this test, verify that the zero sense line (ground circuit) has continuity to the nozzle.
This test is best performed in the audible continuity mode.
Touch one probe to the nozzle or heater block, and the other to pin 8 on the toolhead's connector.
Note: Positive or negative probe positions are irrelevant to this test.
An audible alarm should sound indicating that continuity is present.
If so, the toolhead has passed electrical testing and may proceed to final extrusion testing.
Congratulations!
Put the toolhead onto the test stand and run the test gcode.
Make sure:
1) The heatsink fan is on anytime the tool's controller is powered on
2) That the blower fan runs without being too noisy or jittery
3) That the Hotend heats up in a controlled way
4) The stepper motor moves without skipping
Visually verify the extrusion and make sure there is no debris.
Remove the remaining filament from the tool head
