Hi All my machine c4n4848 tk shorted out at the gender changer and fried my UC 100. I emailed Arturo Duncan with cnc4pc He immediately jumped on my situation with cnc drive in Hungary I'm back in the cnc game only because of Arturo Duncan I give Him 5 stars for Excellence at what He does even with the company in Hungary!When dealing with these issues I quickly understood the saying Patience is a virtue these things can take time.So Thankful Arturo is Our U.S rep!
