Sell 1.75mm Filament Detection Pause 3D Printer Monitor Sensor ule best price

Descriptions: (for Lerdge board) the green light keeps on when filament is in. If filament is exhausted, the green light goes off. At this moment, board pauses operation and it will continue to print after filament is in again. ?Features: Newly designed smart ule for detecting the status of the use of filament. To check the filament is whether run out or not, it automatically pauses the 3D Printer when the filament runs out, so you will have a chance to supplement the filament which makes sure you won't print a incomplete printing. Wear-resistant copper sets added in both the inlet and outlet to effectively extend the product life. is a very practical filament detection sensor ule, ideal accessories for 3D printer, making your printing work smooth and relieved.
