Because the wires tend to block the labels above the terminal block I'm going to show you a
clear photo of the terminal block and then describe how to wire each section.

Since we've already done the Heat 0 position, we'll do Fan 0 next.
Fig. 18-15:FAN 0 location.
The Fan 0 connector is used to control the Layer Fan. When wiring the hot end, the Layer fan
is the 26ga pair of wires that does not have the knot in it. Bring the wire pair foreward as with the hot
end power wires and trim them so there is 6" of wire out past the front of the machine. Strip 1/4" of
insulation from the two wires and insert them into the Fan 0 connector and tighten down the screws for
those two positions. Make sure you observe the wire polarity – remember, "-" is black, "+" is red.
Fig. 18-16:HEAT 1 location.
The Heat 1 connector is where the PEEK fan is wired in. The pair you want is the 26ga wires
you tied the knot into. Like before, bring out 6" of wire, trim, strip and insert into the Heat 1 terminals.
The PEEK fan will be automatically activated when the hot end reaches 50 degrees Celcius.
