+ | ==== Filament sensor pins ==== | ||
+ | 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. | ||

When you try to print, the print may stop (or may fail to start at all), and instead the printer will make a loud beeping sound. | When you try to print, the print may stop (or may fail to start at all), and instead the printer will make a loud beeping sound. | ||
