Hello from, Baltimore USA

Hi Everyone,

I'm Steve. I'm a mechanical engineer for Polk Audio. I'm located just outside of Baltimore, Maryland. I'm also completing a DIY CNC in my home workshop. I have about 15 years experience with Pro Engineer and manual machining with both Milling Machines and Machine Lathes. I have some experience with CNC and programming in G-Code.

I joined this forum as means to gather more information as well as to contribute if I am able.

Regards,

Steve
