Why make a state-of-the-art laser and give you a software that it looks like they paid extra to make it useless. I have wasted six hours to modify an SVG taking it back and forth to Lightburn because the useless XCS keeps freezing up and for getting the diameter I give it. and I finally get it and now I click prosses it does nothing shows nothing just sits there. in short Xtool fix your F-ing software or just don't include any. This is the worst software I have ever used or tried to use.
