Just bought a new USB controller from the BuildyourCNC website after the parallel port on my computer stopped working.
I am having trouble with the outputs on the USB interface board. I am getting no communication between Mach3 and the outputs no matter what I try. I have the ports set to 3 for all the outputs in Mach3. Everything else on the board is working fine, the touch plate, all axis, and the limit switches. I just want to set up the relay to turn the spindle on and off. When I test the outputs with the multi meter I get a constant 0v on output 1 and a constant 24v on outputs 2,3, and 4. Tried a lot of different settings in Mach3 but am unable to get any communication to any of the outputs.
I am running Windows 7 if that matters. Anything else I can try? Is it the board itself?
