Hi,

The boards work exclusively with Mach3 at the moment. Some movement has been made on getting them to work with mach4 but I am still holding off that program.

You will not need a dedicated lan card although the smooth steppers ip address must be in the same domain as the pc you are using. For example, as standard the ip of the board is something like 10.02.30.78. You can easily change that to a more normal 192.168.1.50 if you want. I can do that for you if need be. This address is then static so you can plug it into a router. While experimenting i also had the machine plugged into a router and the pc connected wirelessly, this may not be safest option but it works.

As for performace, all i will say is that in my own experience it work very well. I am hoping others less biased will also chime in here.

The point to make though is that the value for money is very good on these boards.
