Stop missing filament run outs ! Lets you know via App on phone so never waste a print ever again! No modification to printer required, no upgrades to mainboard or flashing required. Simply lets you know when filament is out allowing you to change filament during print or pause / shut down printer, until you get home (Requires remote Power shut down which can also be set up via App / extra Sonoff hardware). We use these ourselves and decided to sell them as thought they would prove invaluable! Uses Sonoff Technology to contact you when Printer runs out of Filament! Current version only designed for Creality Ender 3 or similar models with Box type top Frame. (others coming soon) We do recommend trimming end of filament off before use. Made in the U.K. by Paul E Key.
