Let me try to recap all your posts.
Your LaserBoard came with Smoothie Cluster installed, so you should not have needed to download anything. Are you using the firmware that shipped on the card, or have you replaced it?
Wire color is often not consistent between different lasers. What’s important is to match up the connections properly, regardless of the color.
Did you manage to get your laser set up in LightBurn? Can you jog the laser head around?
How did you fire the laser? Did you run a job in LightBurn? Did you use commands in the console?
Finally, for the GLCD, check the installation instructions. It looks like you have one of the cables flipped around the wrong way.
If you can answer each question I’ve asked above, we can try to get things sorted for you.
