I am trying to setup a computer to run our CNC machine. I am more techy than machinist (BF is the machinist but knows nothing about computers). I had to add two new ports to the computer to connect the plasma. Everything is loaded on the computer. When I launch the Mach3 plasma and pull up a g-code design it does run on the control panel. But it will not make the machine move. I thought it was due to the new ports I added. I do seem the listed under the device manager (under other device and not under ports (COM & LPT) but I can not seem to get anything to run. I am not sure if its the way I installed the software or that I installed the ports incorrectly. Any help would be fantastic!
