Jtech laser stops firing when i move the y axis about 3 inches

My laser was working, today it is not. I uninstalled my lightburn software then reinstalled it and having the same problem after laser homes if i turn the fire button on, the laser will fire appropriately if i start moving the y axis (not z) when i go about 3 inches south, the laser cuts off. see video. If i change the movement to .5 inches the laser will stay on no matter how far south i go. but if i hit frame button the laser cuts off and wont come back on. And if i try to start a burn the laser will not come on

here if i do small increments
