There is almost no videos that show you, with a lot of details, how to assemble the machine, how to set it up so it works with the program. When you open “The instructions”on the USB they ask you to go to a folder, then when you open it, there is a link to the internet, once you click on it; surprise!!! It doesn’t work. Another problem I have is that I keep getting the red light for the air. It doesn’t mater what I do, It doesn’t turn off. Lastly , when I want to do some work, even with the red light on, i get a message saying that the machine is busy and that I can’t send a file because it can’t connect the machine to the computer.
