Help me please

I have a Jtech laser on my xcarve and i went to run it today and opposed to the laser flickering on and off for the light and dark pixels of the image it is stalling and not turning the laser on at all. You can hear the processor of the laser platform trying to turn the laser on, but it just jumps…i cant upload the video on here for some reason, but message me for any input and ill send it to you!
