My back ground is 25 years in the navy as an electronics technician. I then worked for 18 years as an engineer for the Bell South/AT&T. 3 years ago I was given an Ender 5 Plus 3D printer and used Fusion 360 auto cad to design. In May of this year I bought a Falcon 2 22 watt engraver. I’m now experimenting engraving metal, stone, slate, wood, marble and leather.
