Filament Run Out Detection Module FRODV6

Filament Run Out Detection Module Filament Spool Used UP Sensor For Multi Extruder Color 3D Printer DIY Kit Serial Connect Filament Run out Detection is a sensor to detect the filament spool is used up.  The filament run out sensor support to connect in series, so it can use one input port to detection multi filament spools,  it is suitable for multiple extruders 3d printer. FROD can be applied to all of ZONESTAR 3d printer. NOTE1: It can only be used to 1.75mm filament. NOTE2: Random color shell, usually we send red or black .  About Filament run out detectionGenerally, the 3D printer DIY kit is not able to detect running out of filament, it will continue to print until file is completed even if the filament runs out. This always leads to incomplete printing which will be wasting your time and filament.  Based on this situation, you can add a filament run out detection on the 3D printer. It will pause printing when the module detect the filament running out. You just need to change
