The xtool (D1 pro 20W) never worked right for me, for example it could never cut a perfect circle which meant the timing belts needed to be adjusted. But it seemed no matter how much i adjusted and tried to get it just right it never was. Their support is in china so the few times I contacted them it was more than a day before they would respond, then the response would be just sending me a video. The glowforge isn't perfect but I do like that it has the camera so you can see exactly where the cut/engraving will be, whereas with xtool all you have is the framing to tell you where it was going to cut or engrave.
Are you close to Greensboro? If I could take the xtool over to have you look at it and see if you know how to make it work right that would be really helpful; right now it just sits there not being used.
