LulzBot TAZ 5 E3D Upgrade Kit Assembly.

This page provides a comprehensive guide to upgrade the LulzBot TAZ 5 to use the E3D V6 hotend and the E3D Titan extruder. This guide also covers the modifications required to convert your Taz 5 to run the E3D Volcano hotend. Installation instructions can be found on the main LulzBot TAZ5 - Titan & V6 page.

Printed part files can be found on Thingiverse.

Assembly

HotEnd

V6

V6 Extruder Finished Wiring.

The first step is to assemble the V6 HotEnd. Please refer to the V6 Assembly Page for the full instructions.

  • Note that we want the 'direct' rather than 'Bowden' configuration in the V6 assembly instructions. Alternatively, you can purchase an already assembled and hot-tightened hotend.. Make sure to select the 24V Direct version.
  • You must decide here whether to configure the HotEnd for 1.75mm or 3mm filament. 3mm is the standard for the original LulzBot TAZ 5 head so you may wish to stick with this, however 1.75mm filament is becoming increasingly popular.
  • Ensure the wires exit in the direction shown when complete.
  • If installing a custom heating element, only use elements of 35W power or less due to the gauge of the LulzBot's internal wiring.


Volcano

The assembly process for volcano is very similar and follows the same guide as for the V6, see the E3D Volcano Documentation for any differences. The wires should exit in a similar manner to the V6.

Filament Cooling Fan

Use the two M3x16mm bolts and M3 nuts to attach the filament cooling fan and nozzle to the mounting point pictured. This is easiest done before mounting the stepper motor.

Location of Filament Cooling Fan Mounting Points.
  1. Position the nozzle with the most curved side facing down as shown.
    Correct Nozzle Orientation.
  2. Position the fan with the label on the inside facing towards the nozzle and the wires in the closest position to the adaptor base.
    Fan Mounting Direction
  3. Place the two nuts into their seats located in the adaptor mounting point.
    Seated Nuts
  4. Run the bolts through the appropriate two holes in the nozzle then through the fan holes. Align the bolts through the adaptor mounting holes and tighten into the seated nuts.

  5. Repeat this process for the two M3x12mm bolts and M3 nuts in the remaining nozzle and fan holes, this time the nuts are seated directly in the fan.


Titan Extruder

Finished Assembly.

Once the V6 HotEnd has been assembled and the filament cooling fan has been installed we can assemble the Titan Extruder. Please refer to the Titan Assembly Page for full instructions though read this section first as there are some differences.

  • The adaptor plate is mounted between the stepper motor and Titan Extruder, this is referred to as a 'spacer' in the titan documentation.
  • The motor wires should ideally face upwards towards the top of the adaptor plate, if this is not possible then they can face outwards.
  • Mount the stepper motor gear before assembling, leave a gap of approximately 0.5mm between the gear and motor face and ensure that the grub screw side of the gear is closest to the motor. Exact alignment instructions will be given in the Titan documentation.
  • The idler tension screw is replaced by the supplied idler tension thumb screw. This is mounted with the knurled end extending from the back of the Titan Extruder. the second ring is mounted in the slot where the screw head would usually sit and the spring over the threaded section. The printed thumb wheel extension should be press fit onto the knurled outer ring.
  • The heater block should be rotated such that it is a far from the cooling nozzle as possible, with the shortest face facing towards the nozzle and the wires exiting from the rear.
  • The heatsink fan should be mounted opposite to the cooling nozzle.


Wiring

Begin by running all wires through the heat shrink tubing. Cut the wires to length, strip the ends and crimp a crimp pin onto the end of each. The wiring loom should look as in the figure below when complete.

Wiring Sleeve.

The wires must be inserted into the included 16-socket connector housing once the head has been fully assembled. The correct pin placement is shown below as seen from the back of the connector when plugged in.

LulzBot TAZ 5 Upgrade Connector Wiring Diagram.

The crimped pins must be inserted into the connector housing as pictured. Ensure the latch pins face towards the outside of the housing when inserting. The pins can be pulled through fully with a pair of pliers - be very gentle. Once installed, ensure the pins are secured properly by placing light pressure on them with a hard object.

Pin Orientation.

The wires should be run underneath the motor and secured to the cable tie point shown below. Trim the loose end of the cable tie.

Cable Tie Point.

Using a heat source, shrink the heat shrink tubing over the wiring to complete the assembly.

For assembly, please refer to the V6 and Titan upgrade guide.
