Computer:
Windows 7. 64 bit.
Mach3 is installed with working parallel port.
Parallel port testing shows that input signals and output signals are present, but something keeps happening to prevent the CNC Device from receiving the signals from Mach3.
I'm suspecting that there is something wrong between the computer and the CNC Device OR there is something wrong with the Mach3 settings that it doesn't function.
All the wire connections in the CNC device are set [motors step, etc] correctly; i.e. there is power flowing through the system. Mach3 cannot send orders to the device.
