@LightBurn Granted! It DOES work with ANY laser. Proven here to work on a W6- like any raster detail, it’s limited by the abysmal on-off time (<=1mS) with DC-excited tubes, but it’s cranking out amazing detail at 100mm/s for a 0.25mm spot size. I sat down with a microscope to do a pretty thorough analysis of tube bandwidth and dynamic response to understand the process with real-world data.
