Assembled Second Extruder Enclosure Wiring Harness NOT INCLUDED with the KITTAZ or the Dual Extruder Add-on. The connector diagram can be found here.
Zip-tie the wire harness together if desired.
Use zip-ties to secure the wiring harnesses to the KITTAZ frame.
Connect the two extruders to the wiring harness:
Connect the rear extruder motor (extruder 0) 4 color wire connector to the 4 color wire connector within the black wiring harness
Connect the rear hot end (extruder 0) 2 color wire connector to the 2 color wire connector within the black wiring harness
Connect the front extruder motor (extruder 1) 4 color wire connector to the 4 color wire connector within the blue wiring harness
Connect the front hot end (extruder 1) 2 color wire connector to the 2 color wire connector within the blue wiring harness
Loosen the M5 bolt holding the first spool arm.
Lower the exisiting spool arm by ~3 inches.
Attach 2nd spool arm using drop in fastener. Slide the provided M5 T-nut into the aluminum extrusion approximately 6” above the original spool arm position. Make sure that spools can spin freely on both arms without interfering with each other.
Attach 2nd feed tube on original feed tube holder.

Locate your original steps per unit.
Update your local Arduino installation with the required libraries using this guide
Extract the files to a memorable location.We recommend a new folder on your Desktop, or a new folder in your Home folder.
Extract the Firmware archive. Once extracted, you should have the following folders:
Open the Arduino IDE.
Select File > Open .
Navigate to the folder containing the Marlin folder you previously extracted.
Open the file titled Marlin.ino
Once opened, you should see multiple tabs across the top of the Arduino IDE window.
In the Configuration.h tab, update the information found in:
You will need to update the second to last 800 number with the Estep value found earlier.
Change the last 800 value to 840.
Once changed save the modifications by pressing CTRL & S or by selecting in the menu File > Save.
Connect the KITTAZ to your computer with the supplied USB cable.
Once connected, in the Arduino IDE menu, select:
Upload the firmware to the TAZ 3D printer by selecting File > Upload Sketch or by pressing Ctrl & U.
The firmware will now compile, then will upload to the board. Once finished, the Arduino IDE will display a completion message.
