Laser not working but fan is spinning

Hi there!

I’ve been working for a while on a custom laser engraver, with the MKS-DLC32 V2.1 board as the controller, but I have a problem regarding about the laser itself.

I tried everything, from changing configuration parametres and changing cables but the laser beam does not light up at all, only the fan being the one to work.
Here is a picture with the laser itself (also to mention that it’s having a 3-pin connector that goes to the board):

Do you guys think that there’s a problem to the board or the laser? Maybe the laser is not compatible with the board?
Hope getting an answer soon.
