Laser output low

Items currently on laser
X7 DSP Controller
LO 20W-40W PWM Power Supply
SPT 45W Laser Tube- Light Object tested 45W at 13ma 53W at 18ma
Laser size: 1200mm x 900mm engraving area
Current Issue: Controller will not fire laser more than 5ma
If I test fire the laser through the power supply the MA meter shows 10ma. If I test fire through the X7 the MA reads 5ma. If I send a file through lightburn to the controller and run the file the max output during the execution of the file only shows 5ma at the metere. Settings for the file show 80% power but only get 5ma. If I adjust file settings to 95 percent, I only get 5ma. It seems that no matter what I do I can only get 5ma through the controller to the laser.
I adjusted the max setting for the laser in the manufacturer settings to 98 percent (I know it is high, it was just to test) Max min output is 0.
Water protect is enabled and is run through the flow sensor purchased through LO. It was a three wire model. I supplied 5V to the meter from the controller, yellow signal wire is connected to water protect port, black ground wire connected to controller ground. Water protect is jumpered to ground at the power supply. I have tried removing the water protect at the controller and jumping it to ground and still only 5ma.
Power to the controller is provided by a 24v 14amp power supply running the controller and stepper drivers.
Power supply is on a 15 amp switched breaker box. Potentiometer on the power supply is on max. Will turn down when I get this figured out.
Pinout:
TTL connected to L port
PWM connected to IN
Ground to ground
H no connection
5V no connection
Am I missing a setting in the controller to get a higher output? Is there something wrong with the wiring? I used the diagram found on the LO forum. I only want to run the laser at 13ma.
Controller runs the file perfectly all drivers and motors run smoothly and cool to the touch, but I just can’t get a higher output for the laser.
