Introduction
NOTE: This guide is applicable to most TAZ printers, but is specific to the TAZ 5 printers manufactured after July 2015. Versions prior to these had multiple smaller pin harnesses for connecting the hot end electronics, but the wires were all the same albeit in a different configuration.
Tools
-
-
Make sure the printer and power supply are off and unplug the power supply from the printer.
-
Remove any filament from the extruder assembly.
-
-
-
Unplug the pin harness.
-
Using a 2.5mm hex key, remove the M3 screw securing the extruder assembly to the carriage plate.
-
Lift the extruder assembly up and off the carriage.
-
-
-
Using a 1.5mm hex key, remove the M2 screw securing the old blower fan.
-
-
-
Remove the following pins from the extruder assembly-side wiring harness:
-
Pins 5 & 6: Heater cartridge
-
Pins 9 & 10: Blower fan
-
Pins 15 & 16: Thermistor
-

-
-
Take one of the four screws from the layer fan and screw it in to one of the inserts, leaving enough length to grip it with a pair of needle-nose pliers.
-
Heat up the screw with a soldering iron and apply upward pressure with the pliers until the insert comes out.
-
Repeat for the other three inserts.
-
-
-
Place one of the four inserts you removed in the previous step over one of the holes on the new layer fan shroud.
-
Insert the soldering iron straight down into the hole as shown in the first picture and apply downward pressure until the insert sinks into place.
-
Repeat for the other three inserts.
-
-
-
Cut the wires 125mm from the top of the heat sink fan as shown.
-
-
-
Strip 4-6mm off the end of each wire.
-
Crimp the Molex male terminal pins onto each wire.
-
The pins have two sets of tabs. Use a set of needle nose pliers to fold the inner tabs over the bare wire. Fold the outer tabs over the insulation.
-
For extra security, solder the pins onto the wires.
-
-
-
Install the pins according to the pin diagram from earlier:
-
Pins 5 & 6: Heater cartridge
-
Pin 9: Blower fan red
-
Pin 10: Blower fan black
-
Pins 15 & 16: Thermistor
-

-
-
-
Remove the four M3 screws securing the access plate to the control box.
-
-
-
Connect the printer to MatterControl and set the extruder temperature to 260°C.
-
Using a 7mm socket wrench and an adjustable wrench or tongue-and-groove pliers to hold the heat block steady, tighten the nozzle.
-
-
-
Unscrew the thumbscrew almost all the way up.
-
Home the Z axis.
-
Depending on how far the nozzle is from the bed, screw the thumbscrew down a turn or two at a time.
-
Repeat homing and adjusting until the nozzle is the distance of a paper's thickness away from the bed.

You have the wrong e3d link. Make sure to buy the 24V, 3.00 mm version, NOT the 12V, 3.00mm version.
I decided to buy a 5V 30x30mm fan to cool the cold end instead of the 12V fan provided with the E3D kit. This removes steps 18-25. The wiring/connectors for the 5V fan go where the blower connectors used to be. I can easily swap out the entire head and replace with my dual extruder when needed.
Thanks, Matthew; good catch! The link has been updated.
What's the advantage of 5V? I've seen RAMBo boards have trouble supplying enough power to heat sink fans and heat creep occurs, so I just wonder why you chose 5V instead of 12V.
Lulzbot decided to use 5V for their micro blower (why 5V and why a blower.. that CFM/pressure drop curve). If you have another Lulzbot toolhead you can keep the cold end voltage cooling mechanism consistent. There's certainly nothing wrong with the steps provided.
Ah yes, I forgot about the 5V micro-blower fan-- it's been a while since I tinkered with the TAZ. Thanks for your input!
