Hi to all!

I have chinese engraver with 80w tube, 1290 clone model and 6515 controller using Lasercut 5.1 software. I cannot figure out how to control PWM settings in software, no matter how do I change them I always get same results. Default value is 20000. I was trying values ranging from 1 to 50000 but no changes.
Does anybody have any idea how to control this? My problem is when I cut some kind of foam (in my country we call it EVA foam) for making key-chain tags (sorry for my bad english) I get very charred and dirt edges. I know that when using Epilog or GCC laser you can change PPI values and hope that PWM setting have the same effect on chinese lasers.

Thanks in advance
