Hello, I am a CNC operator. It’s been used a year to use it. It was very difficult when I first started to use it, but the staff visited whenever I need. Every time I work on, I could learn new functions so beginners can use them conveniently. It is easy to work on electrode. Especially for beginners! It is really easy to use. It takes only one month to learn. When they visited me, they set me upgrade version. I like it very much. They are so Nice and kind.
