When the material is used up, the green light goes out. The main board executes the pause command operation and waits for the personnel to replace the good material and then continues to print. Lerdge main board wiring: M sensor port on the main board. For other boards: material detection module uses level jump detection method. When there is material, the level signal of the detection port should be high. When there is no material, the level signal of the material port becomes low, and the system detects one. If the high to low conversion is determined, the material is considered exhausted and the pause command is executed. After humans change the material, the printer continues to print. Suitable for 3D printer run-out, pause detection.
