I'm taking Russ's recommendations to sign up to learn a lot more about laser cutting. I was doing okay, but when I put on a rotary Chuck had a hard time but i got it up and running . When I went back to regular settings that's when the disaster hit I lost everything . Russ was very informative. I learned quite a bit and hope to learn a lot more by this forum. this is my first time joining a forum so a helping hand would be great.
