Laser not pulsing

I recently purchase a laser with a leetro controller. I wanted to run Lightburn software so I switch to a ruida 6442 controller. Everything went well but I am having issues with pulsing the laser to help align the mirrors. I can fire the laser by disconnecting the controller and hitting the test fire on the PSU. Not sure if this is a setting problem when I set the controller up thru lightburn. I don’t show any alarms on the controller. I don’t have a water protection switch. I am running a CW5000 chiller which is running. I have adjusted the pulse time a few times but I still get nothing. Any help would be great. Thanks!
