I have also purchased this controller card and I as well cannot get it to jog. I have done everything that the manual says for the setup of this board for the ports and pins and it will not jog. I have also followed all the advice that the people on this thread has given and still the jog function does not work. I have also checked and made sure that the jog function was turned on in mach3. I am running windows 10 and I have a router hooked up to the computer and the board and the router does see both devices. I have disabled ALL firewalls, windows and my antivirus programs ones. When I open Mach3 I can test my e-stop and that works and also I have tested my probe input and that also works so I think that the board and the computer are talking to each other. Any help would be appreciated, thank you.
