Laser cutting paper question

[...]) This will bring up your advanced options. Lower your frequency from 20000 to about 500. This should help. If this does not make a difference, change your overlap. If you PM me I will give you my number and I'll help you out over the phone.

I have tried to change frequency in Lasercut but it doesn't make any difference. I'm trying to cut EVA foam but I get really dark edges.
How is your Lasercut set? My settings in preferences for Motion card for laser control is "Analog settings", when I set to "PWM" I get clear edges, but I cannot control power for engraving, seems like it is always set to highest power.
Anybody any suggestions?

thanx in advance
