In Arduino IDE

I have been trying to get my Laser Engraver working but I'm at a stand still. In Arduino, I have gotten as far as getting "BLINK" to blink. Now where do I go from here? I have the App "Laser GRBL" loaded but I can't activate it and I downloaded Universal G Code Sender. What haven't done to get my laser engraver going.
I really need HELP.

We really need details.
(This isn’t a laser engraver forum)

But isn't it a place to get help with Arduino Uno in setting up Arduino IDE to run laser?
