We are selling a U-Marq Versatile Engraving Machine - GEM-FX5, it was bought at a tool auction for the state of Oklahoma. I haven't a clue how to test it and have no accessories for it that are not pictured. Anyone in the OKC area is welcome to contact me if you want to test it otherwise it is being sold as is. I plugged it in and it powered up, that's all I know (Look at pictures).
