my DK5 has developed a fault. everything seems to run properly, but it no longer burns anything and the intensity of the laser has diminished. does anyone have any suggestions? i have tried adjusting the focus and checking the power input.
setting the focus is trial and error. if you want to increase the size of the image to maximum, you could try resizing the original image in an image processing app such as GIMP. I use Paint Shop Pro. If your image is colour or greyscale, I'd advise using your image processor to clean the image and convert to 2 tone before loading it onto the Neje software.
