    Extruder wiring

    I have a Anet A8 3d printer, every diagram that I look at only shows two wires coming from the extruder, but my extruder has 4 wires does anybody know where them for wires go like in a wiring diagram thank you.

    The actual part called the extruder has a bipolar stepper motor to drive filament and has 4 wires that get connected to the board as an extruder output maybe labelled E0 E1 and usually next to other axis stepper motors. If it is a direct drive system the extruder part is connected to the hot end part with nozzle and it will have two small wires that are the temp sensor called a thermistor,, along with that are two thicker wires that are connected to a heater cartridge to heat filament those wires get connected to board. The thermistor plugs into the board while the heater usually connects to some screw terminal blocks
