i have a Cincinnati laser CL-707 2500 watt, well when i bought the laser they told me that it can cut up to 1/2" on HRP&O, well we have been playing with it and so far we can only get 5/16" to cut good. 3/8 and 5/8 and 1/2 still look like crap. We have changed the lense settings gas pressur and some other things. I was wonding if anyone else had any other idea. It would be a lot of help, THANKS
