Hello. First time poster here. I recently finished building my cnc router and now Im at the lets test it out and see what i need to do to work the bugs out. Im running Windows 7 32 bit, my motor controller is STDR 4C, Im using the the parallel port on the computer to link the computer to the motor control. The cable to link the two is about 5 feet long. It is actually two cables, one male to female and one male to male. I downloaded the Mach 3 and went by the instructions and Im able to tinker around with the software. The emergency stop does flash, when i press the reset, "Emergency mode active" scrolls across and "external Estop is requested" is at the bottom of the screen. On the diagnostic page, 5 green lights on the Port 1 pins state are one, rest are off. Any suggestions on getting this resolved and getting this to get my motors to move.
