The laser doesn’t emit light after being connected to marking board

in FAQs about Laser Marking, ,

After the laser is connected to the laser marking board, it does not emit light. What are the causes?

There are four reasons:

First, it is not on the focal plane;

Second, the laser type parameter setting problem;

Third, the laser control interface CON2 is not completely contacted;

Fourth, test the output value of the laser output signal PWM signal to determine whether the board communication or the laser is faulty.
