- Color: White
Used with Lerdge board:
When there is filament in, the green light in the module keeps lighting. And when the filament is exhausted, the green light goes off, then the motherboard executes the pause command operation, after the replacement of the filament can continue to print.
Wiring: Connect the module to the M-sensor port on the motherboard.
Used with other motherboards:
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.
