Items required

4 Position the Z axis

Let's get started!

Power on your LulzBot TAZ 3D printer.

Raise the Z axis by using the Graphical LCD controller to print the calibration/z_shipping_245.gcode file found on the SD card included with your LulzBot 3D printer. The file can also be downloaded from here. To save the file, right click on the link and select Save as or Save target as.

Alternatively, you can also manually move the Z axis up by using the Graphical LCD controller by navigating to: Prepare > Move Axis > 1.0 > Z axis > Change the value to at least 200.

Raise Z-axis

5 Power off your LulzBot 3D printer

Completely power off your LulzBot 3D printer and unplug the power cord and USB cable before proceeding.

Power off yout TAZ 3D printer, disconnect the USB cable

6 Remove existing tool head

Unplug the connectors for your current tool head. With one hand support the tool head and unscrew the single M3 screw securing it to the X axis carriage, and remove it from the printer by lifting the tool head up.

7 Record Flexystruder ESteps

Your new Flexystruder has a different Extruder Steps Per Unit (ESteps) value than the standard TAZ tool head. This important new value can be found on a sticker on the back of the extruder.

Record this value before continuing.

15 Load Key Chain Model

In Cura LulzBot Edition, load the key chain test print. The model can be downloaded here:


Locate the included glue stick.

SemiFlex and NinjaFlex will adhere exceedingly well to the print surface. To aid part removal, evenly apply glue stick to the print surface.

Failure to do so may cause the printed flexible part to bond permanently to the PEI print surface.

Apply glue stick

16 Select Material And Quickprint Profile

Under Material select NinjaFlex (Fenner Drives).

Choose the Standard quickprint profile.

Remove the SD Card from the TAZ 6 Control Box and install it into your computer.

Save the sliced model to the SD Card by pressing the Save GCODE button.

Select material and save GCODE

17 Prepare Your 3D Printer

SemiFlex and NinjaFlex will adhere exceedingly well to the print surface. To aid part removal, evenly apply glue stick to the print surface.

Failure to do so may cause the printed flexible part to bond permanently to the PEI print surface.

Turn on the hot end through the Graphical LCD by navigating to Temperature > Nozzle > 225.

You are almost ready to print!

Apply glue stick to the print surface
Set Extruder Temperature

18 Remove filament

Your Flexystruder tool head was calibrated before leaving our factory. Once the printer is up to extrusion temperature of 225°C, remove the filament.

Through the Graphical LCD, navigate to Prepare and select Motors Off. Rotate the large gear by hand clockwise to remove the filament from the hot end.

Remove filament

19 Load And Extrude Filament

Load the NinjaFlex filament sample into the extruder body.

Slowly rotate the large gear by hand, counter-clockwise, to feed the filament into the hot end.

Once your 3D printer is at the appropriate extrusion temperature of 225°C, finish loading the filament by rotating the large gear counter-clockwise until the extruded filament underneath the hot end nozzle transitions to LulzBot green.

Load flexible filament sample

20 Your First Flexystruder Print

On the Graphical LCD controller, select Print from SD and navigate to the keychain.gcode file. Select the file to begin the 3D print.

Your LulzBot TAZ 3D printer will automatically do the following:

  • Home each axis.
  • Set hot end cleaning temperature.
  • Once the hot end cleaning temperature has been achieved it will retract the filament.
  • Nozzle cleaning routine.
  • Bed level probing: Watch this process! If the print surface is visibly compressed during the probing sequence your nozzle is too dirty. Power down the printer, cancel the print, and home the Z axis. Wipe off the warm nozzle with a clean dry cloth.
  • Once the bed level probing is complete the hot end will warm to the required printing temperature.
  • When the hot end is at the appropriate temperature, your 3D print will begin!
Printed flexible key chain

21 Remove Key Chain Once Cool

After the key chain has been printed the tool head will move away from the completed model. The bed will move forward once the printer cools to the recommended part removal temperature.

Remove your printed object by using the blue-handled pry tool to lift the part from the bed.

To switch back to the original tool head, follow the same steps outlined in this guide, except this time, select the Standard LulzBot TAZ 2.1 tool head and options.
