LaserUser.com Forum (formerly RDWorksLab)

Hello to RDworks Lab community from western siberia!
I am junior product designer in local FabLab and recently was tasked with operating 60w CO2 Laser-engraver.
Recently stumbled on one of the Russ's videos about lenses and was fascinated by his dedication and research discipline.
Hoping to get better understanding of engraving techniques and photo preparation for engraving

Welcome Mikhail- Russ is usually the final authority but we have very smart and helpful members too, so read as much as you can and then ask any questions you might have. Gene
