for "New Engraving Machine Guide Rail Linear Slide Orbit for Engraving Straight and Round Woodworking DIY Accessories Tools" you should specify that it does not come with a guide rail and a milling machine plate that mounts to the guide bracket. I'm most disappointed with is that you misled me with the "New Engraving Machine Guide Rail Linear Slide Orbit for Engraving Straight and Round Woodworking DIY Accessories Tools" and I can't use it because I don't have all the accessories.Otherwise the quality of the materials is good, the delivery time and tracking of the package is very good.
