General Mach Discussion / Motor problem

« on: December 09, 2008, 07:35:10 PM »

Hi, I've just joined the forum, having just built a CNC Router. After having problems getting an output from the parallel port, which I eventually  found was a problem with the port driver, I now have an output, but the motors will only oscillate. They move in one direction for a fraction of a revolution, then reverse for the same amount continually when in jog mode. All my electrical equipment is Keling.
