I am having trouble engraving an image. I want to do grayscale and have spent many hours changing settings and not really getting anywhere. I am posting a few pictures on my settings and a couple pictures of the laser job. The first one is the grayscale test box and the second was on Jarvis. I am using shapeoko 3 grbl 1.1f and a 3.5w laser. Any help would be greatly appreciated.
Sorry about the bad quality pictures on the settings. Took it from my phone looking at the computer screen.
