(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.
Newly designed smart module 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 module, ideal accessories for 3D printer, making your printing work smooth and relieved.
Easy to install, and work steadily and durable in use.
The filament detection module uses the level transition detection method. When with filament in, the detection level signal should be high, and when no filament, the filament port level signal goes low. When the system detects a determined transition from high to low level, it will regard it as the filament exhausted, then the board executes the pause command operation, and after the replacement of the filament, it will continue to print.
