Laser not marking wood

H I am totally new to all this, I Have an Alfawise C30 laser and have lightburn, when I press go the laser light comes on it moves ok with the shape I have but it is not marking the wood, what am I doing wrong ?? help

The “Alfawise C30” looks like a little diode setup but we would need to know what controller and firmware is driving this to offer more help. What profile did you use when setting up LightBurn?

The firmware is GRBL

I don’t understand what is ment as to what profile was used when setting up lightburn, could you explain to a complete novice please

I have used the focus test and that burns fine

Thank you

What do you see down here?

And what does it say in the console window when you first connect it?
