Cleaning block, testing laser

[3W Hank]

I finally got the laser ( 1500 W ) my buddy bought a 3000 W and he did some testings but its not that easy set it up and not rip the material up.
But its a matter of adjustments.
Ss I bought it ’not’ effect surface, only on microlevel surface remove.
Se my laser and my buddys settings on thicker cast irion.
Its 5 settings that can be endless variations…
What hate is see nice machined cast irion get ripped.
