Red line does not display at all

I have the QS-50 LiteMarker 50W Split Laser
Engraver Fiber Marking Machine. When I first used EZCad 2 lite for testing and setting the focal height the program would display the red light outline. Now the red light does not show except for the the alignment dots. However, neither the outline square, nor the contour outline display. I have checked the ports and check boxes under parameters and configuration and everything looks correct.

You need to test your power supply, if possible, please leave your email, I will let the after-sales staff contact you

I ended up uninstalling Lightburn and re-installing the driver for EZCad and the red light works now. Eventually I will figure out how to switch to Lightburn software. I just wanted to make sure that the Laser works since we just got it recently.
