How precise is the Glowforge?

Hi @omar.bakht. Welcome!

Some of the answers you are looking for are here.

Positioning precision to 0.001” (0.025mm)
Engraving at 1000 DPI with 256 power levels

The spot size is a little more difficult to quantify.

Laser Quality — Beam diameter of less than 5mm at aperture and divergence of less than 1.2 mrad

At the focal point, its dependent on the material.

Here is a thread where they talk about it some more.

I believe someone else was talking about wanting to make Fresnel lenses with their Glowforge.
