I had the same problem as Atomic Shrimp's. I was following his set of videos on YouTube, but he found the answer at the above link Which I'm not privy too for some reason.
Perhaps someone can save me the trouble of looking there by explaining how I change from a laser to a plotter allowing the 'Pen' to get raised and then lowered every time it finishes a stroke.
Something about changing to an A1, well that was what Atomic Shrimp was saying in his video, but he didn't elaborate on it. So I'm still in the dark
