I have got an E3D nozzle as gift theses days. Now I am thinking of installing it on my Mendel90 printer (original nophead set).
the mechanical part itself should be no problem for me.
What concerns me is how to wire the nozzle to the Melzi controller, especially the fan.
How do I connect the fan to the board? Do I have to make a new wiring and which connectors on the Melzi board must I use.
