The screen shows that the laser power is 100%, but there is no light emitted from the laser module. The laser does not emit light under working conditions. Since the. There are a number of checks you can perform when your work encounters a malfunction to try to identify potential problems with working with the laser module, its possible causes, checks you can perform and possible solutions for each problem. After referring to this article, if you are still. After a few cuts my brand new laser (Atomstack A10 pro V2 Black) suddenly did not ray (burning / firing), at the same time It is moving properly, fan works, two leds at laser module works (pwm is blue, power is orange). Such bad behavior exists both: under WIFI via Atom Stack Mobile app and USB. The KY-008 Laser Transmitter module can be used as a laser pointer. It emits a dot shaped, red laser beam. Compatible with Arduino, Raspberry PI, ESP32 and other popular microcontrollers. This problem can halt production and lead to frustration, especially in critical projects.
