Looks like any old grey scale height image I’ve seen, nothing Master grayscale engraving on black anodized aluminum with the RAY5 laser engraver. Hi all My understanding the way a fiber mopa laser works is by providing varying degrees of power depending upon the shade of each pixel - from max power for black to mimimum power for white, which will give depth Welcome to 3D Grayscale, the world’s fastest growing independent website for 3D Height Maps. I saw that grayscale produces the best results. Try to get the black so it is not burning Here is my situation. RE: Unable to change min power on image KingBubbaTruck (Brent Dowell) September 19, 2019, 1:50am 3 Simply desaturating an image will yield grayscale, but it’s not likely to give you the contrast that you need.
