| + | The pins for the filament sensor belong to the 6-pin header pins near the centre of the lcd module. The top two pins, in the right column of pins are used. There is a problem with the choice of connector JGAurora have used. | ||

| + | Note: This issue has been resolved by JGAurora in recently manufactured machines by using hot glue to both insulate the other pins, and to hold the connector in place correctly. | ||

| However, if you want to use this feature, you can do this simple trick. Turning the connect 180 degrees, will make the metal side contacts face away from the other column of pins. Note that the JST connector they are using has three sockets, but only two are used. You need to make sure that the two wires are still connecting to the same two pins, but in this case we are effectively reversing the polarity. This is not a problem – the sensor is a simple mechanical switch, so it does not matter which way electricity flows. | However, if you want to use this feature, you can do this simple trick.
