Laser Power and Speed setings

Hello,

I have an 80 watt Chinese laser that I purchased from a guy in Toronto who builds the machine from scratch using Chinese parts. My machine will cut 1/4" plywood (with MDF core) using 100 power and 5-6 speed. I usually have to run the cut twice.

I have a friend who has a 40 watt Trotec and she cuts the same plywood at 100 power and 18 speed running the cut once.

Can anyone explain the difference in performance?

Thanks, Robin
