The Epilog doesn't have enough memory to hold the entire raster bitmap, so my laptop is etching itself from inside the laser over the wifi. Parameters on the NYCR laser with my command line tool were raster at 40% power, 100% speed, no vector. Focus is really key; the outer edges of the laptop are unetched due to the curvature of the MacBook Air. I've read that it is important to exclude the logo in the middle to avoid damaging the screen.
