    I have a I3X , I wonder if this dual head will work for me, and if so is this the only upgrade i need to do ? will it work with my controller ? i think in my kit, the controller is "GT2560+ 4 A4988"... would love to any instructions and knowledge about this potential upgrade.

    • Quentin Qiu | 01/20/2016

      Hello Barry, yes this dual extruder can be used on I3X, and you don't have to change the control board. You can contact our sales to purchase the whole upgrading kit.

  • Daniel Bass | 01/04/2016

    Will this work with the FF Creator/Wanhao Replicator 4x/CTC clone machines? They appear to be 24V boards.

    • Quentin Qiu | 01/07/2016

      24V voltage is OK, but you need to check if the installation holes on you printer allow you to install MK8 extruder or not.

  • EDUARDO MOGROVEJO | 11/06/2015

    Hi. I have a i3 X and bought a kit to upgrade to dual extruder. I received the kit and this have the MK48, the aluminum bar and 3D printer parts to mount it, but the 3D printer parts (2) are for the Prusa i3 C, How a get the acrylic parts to mount the dual extruder en my i3 X? thanks

    • Quentin Qiu | 11/12/2015

      Hello,sorry for the late reply.Could you tell me your order number and where you bought the 3d printer? Then I can inform related colleague to help you solve it.

  • Luca Cornalba | 10/08/2015

    Hi. I bought a new MK8 Dual Extruder. Now it's configured for 1,75 mm. filament. What should I change to upgrade to 3,00 mm. filament? Thanks for attention.

    • Quentin Qiu | 10/08/2015

      Hello Luca, you can see on our website that every extruder of certain diameter has two types, which are corresponding with two kinds of filaments:1.75mm and 3mm. Now you are using the extruder for 1.75mm filament, and if you want to change to 3mm filament you have to change all the parts on the extruder except for motors. So you are advised to buy a new extruder for 3mm.

      • Luca Cornalba | 10/09/2015

        Hi. Thanks for the quickly answer. I have to change: - the barrel - the motor drive gear - the idler wheel - the nozzle I think that no other parts are needed to change to upgrade. Can you say me where can I buy these parts?

        • Quentin Qiu | 10/11/2015

          Our salesman will get in touch with you, thank you.

  • Rio Ong | 08/11/2015

    I'm having oozing problem from the inactive extruder. What should be the value of the "retraction length" and "extra length on restart"? What other setting should I change in Slic3r?

    • Quentin Qiu | 08/31/2015

      Hello Rio, please tell me which type of printer you are using so that I can provide you with correct parameter.

  • Sam Kass | 05/24/2015

    What changes if I select PLA vs ABS when ordering? Can't the same nozzle be used for both materials?

  • Sam Kass | 05/24/2015

    Can this be used to upgrade a MakerBot Replicator 2 to a dual-extruder configuration like the 2X? Does it need special adaptation to do so?

  • Ellen swift | 05/19/2015

    what is the distance between the two nozzles, can i buy this dual extruder and use it on my Geeetech i3 pro?
