I have a question for you about my Hurco Hawk 5. I was wondering if there was a way to input cad files onto the ultimax 3 controls other than the 3.5" diskette. Maybe an upgrade to a usb drive, that way I can just take my thumb drive and put a program on it and transfer it to the conversational system. I have no way of putting a cad drawing on a 3.5" floppy anymore.
