How to install the MK8 Dual Extruder?

[vad7]

Printer - Acrylic I3.
This MK8 Dual extruder (http://www.geeetech.com/mk8-dual-extruder-p-921.html) does not fit onto the dual extruder bracket for I3C printer.

Could you please take some pictures, show me which part not fit?
We can guarantee that the extruder holder and extruder bracket fit the dual extruder.

If I remove these parts the cooling will be worse.

I think it's not that worse. When we tested dual extruder, we use only one fan, and so far it's been working well for several months.

Ok, Why you sell it with two heatsinks and fans?

[zhangxueyou]

Did you buy it seperately?
Generally, when you buy a whole printer, we send dual extruder with 2 fans in case of one is dead, but no heatsinks.

I buy MK8 Dual extruder (link - http://www.geeetech.com/mk8-dual-extruder-p-921.html) and don't understand why you send me extruder with two heatsinks + fans if I need to remove them.

MK8 Dual Extruder not only fits i3 C printer, but also fits some other brands of printer.Considering this, we add heatsinks when we sell it separately. After all, 3D printer is a DIY product, we not only consider for people who use our printer, but also people who use other printers.
But when we sell a whole printer with dual extruder, we remove the heatsink and leave only 1 fan, because we've tested one fan without heatsink and has no problem.
Sorry for wasting your time on removing the heatsinks.
