This is another test grid.....but not just a test grid, it is a imported image test grid for bitmaps to be made color in Jarvis mode!!! Most test grids restrict you to mm/s. I have taken the time to create you a test grid that is stepped in power% and Dot Duration. It is set up as 1000DPI but can easily be adjusted. Please be sure to take into consideration metal is VERY reflective so offset your material from exact center to avoid damaging lens or laser. Please also review the image I uploaded. The colors are altered by the angle at which the laser is working. Good Luck and have fun making your imported bitmaps colorful!!!
