I have just received a new prize to add to the seminar. We will have a brand new Ethernet based smoothstepper, bundled with a Mach3 license, to be the 3rd place prize.
This is like the USB smoothstepper, except using ethernet. That should help in some of the cases where USB had ground loop problems. Ethernet is much more tolerant of noise and ground loops. This unit also has more I/O- essentially 3 parallel ports. That will be great for adding more controls, or maybe big operator control panels.
Tickets are still available, but going fast. Last year we sold out before the show date.
