Homing Issues-cannot find limit switch

I have a two tree engraver. 4 hours later and we are still getting an error Alarm 9 homing failed cannot find limit switch. Please help!

Try homing it and manually activating each switch. Does it stop?

Do you have your X and Y limits set in your machine settings? Those are set up your basic settings. Also do you have your origin set? usually for a diode laser it should be the front left of the machine and it is also set in the basic settings.
