OK ,redownloaded . I think it isn't asking where to save . So it just saves to my lap top . Now when I click on it , it opens and installs on lap top including the port driver . so when I send to the thumb drive I don't get the installers for my CNC pc . Does this sound like something or what. This was my first worm out of the can,the reason I looked for the driver test in the first place . So what I 'm trying to say is I do not get any movement at all . This made me think about parrallel port not talking to gecko controller ect. Thanks Bern
