Hi , I've got a C25 smooth stepper board/ with Ethernet cable hooked up to my PC. Mach 3 and drivers are installed and seem to be working. The problem is when I hooked up my steppers and drivers, the arrow keys do not function. The PC seems to know there is a breakout board. I have uninstalled and reinstalled everything twice over and there is something I can't seem to figure out. I do have a parallel port on my PC, but figured the Ethernet would be better. Any suggestions please help, thanks.
