I am beginning to question high speed engraving with an RF laser. The underlying principle seems to be limited by the power available. The higher the engraving speed the more power is required to match the damage threshold of the material you are marking. That is a simple physics fact. So is high speed engraving with RF a bit of an illusion where the engraving speed is actually low but the acceleration is high. This video shows how slow speed and high accelerations can yield faster cycle times under certain circumstances and that depth of cut( colour) disappears as speed increases.
RF refers to the means by which the beam is generated and not the manner in which the beam is controlled. That control is managed by a simple fixed amplitude PWM signal that allows only duty cycle and frequency control.
I will go hunting for some POSITIVES in the next session. Response speed promises to be one.
