Vectric uses proprietary file formats. If your friend didn’t export a G-Code file (extension .tap, .nc, &c.) and you have a .crv or similar file you’ll need a copy of Vectric’s software or your friend will need to export to G-Code with appropriate settings and inform you as to the details of stock type and size, origin relative to the stock, and where/how it’s safe to clamp. (verify that with a simulator such as Camotics).
