Distance from surface

How far from the surface should the laser be
to get the best result

The focal distance of the lens, which will vary based on what laser you have and what lens is inside its head.

I have the Jtech 3.8 W
And the lens with finer beam

You would need to contact JTech for this information, or do a ramp test to determine the optimal focus point.
