Thanks

RE: Hello , I am working with a prc
We always assumed that point would be focus on the material surface.
Another method I used was to set the cutting nozzle so the beam was just 'kissing' the edge of a block of plexiglass. I made a quick burn, and I could see the beam waist burned into the side of the plastic.
Easy on some machines, not on others.
ymmv.

RE: Hello , I am working with a prc
I have 2 PRC's mounted on NTC systems. I also was a service tech with them for 7 years, so I do have some info on PRC's.
Hybrid: 7.5 lens, 2mm nozzle, .060 mPa oxygen, +1.5mm focus, +1.5mm nozzle deflection, 2800 watts CW, 45 inches/min.
Flying optic: 7.5 lens, 2mm nozzle, .070 mPa oxygen, 1mm focus, +1mm deflection, 3200 watts CW, 50-55 inches/min.
I could go faster but it cuts so well that I am happy. Your parameters probably should be around those since your mode size in your PRC should be close too mine in both my systems.
