+All settings at 40W - 20000hz pwm
+F600 = 600 millimetres a minute.
 Note : 73% on my unit runs the laser tube at 18ma. This is the maximum current that should be put through a 40 watt CO2 laser tube.
 
 Cut Perspex = F300 @ 73%
 Score cardboard = F1400 @ 9%
 Cut Paper (Pulsed) = F600 @ 8% - 60ms pulse 2 pulse per millimetre.
+Cut vinyl on paper backing = F600 @ 8% - 4 pulse per millimetre.
