Has anyone used the Atomstack 70w diode?

I’m looking at upgrading my current setup. I have an atomstack 20w. I’ve been able to do a fair amount of stuff with it, from glass cups to slate. I know from the stats and a few videos, it will do pretty much everything I’m already doing much faster and more efficient. What I would like to know if this:

When engraving stone, specifically red brick (paver brick), do you guys think I would get the same burned/fused black look that CO2 does? I can engrave it now, but it turns out white, which is far less desirable. I’m just wondering if I can get an equivalent effect with the 70w.

Thoughts?

Thoughts:

  1. Do not expect the level of detail you get with the 20w. The laser dot will be somewhat larger, which will wipe out the finer details.
  2. No. CO2 is a different frequency than the diode. A more power diode will just give you more white.

it will turn white when you are overheating it, I do red brick with my 5 watt diode and have the same issue, just lower the power some
