    LC 3015 F1 NT 4kw laser, problem to cut thicker materials!!

    these values worked for me. but they where tuned for a resonator that was in need of cleaning. changed all mirrors and haven't tested how these cut after that. my theory was that going slower with lower power and duty helped the resonator keep cutting. also a dirty or old bad focus lens might...

    amada fom2 mode shot

    hi. can anyone say what mirror in resonator cause the sharp peak in the center. Fanuc C4000i-B resonator. beam mode taken at 5 meter mark. hot mode looks good but has a sharp peak in the center. maybe 6-7mm long. cold mode does not have this long peak. the problem that started is that cutting...
