Laser not centered!

I have been fighting this issue for over a year and can’t resolve it. I need to position my laser in the center of my layout. Have tried every thing in forum I have read to adjust this. Attached pic shows where my laser supposedly is, it is NOT, it is in the center of my table. I CANT FIGURE THIS OUT. My laser is 30W diode laser, controller is Keyestudio V1. My machine is 24x36 DIY combination router\laser. Running Win10.
