We recently purchased a used CNC and controller. The person who sold us the machine demonstrated with their own computer that the machine works fine. However once we installed Mach3 on on computer we have not been able to get the machine running. We are using the exact same profile/settings the previous owner used. All seems fine on screen, but the machine will not move. We've tried installing Mach3 on several other computers including Pentium II, III and IV, all with built-in parallel ports. Since that what not working we figured maybe not enough voltage to the parallel port, so we installed PCI parallel port that supports 5volts, but with no luck. We have compare he original owner computer settings to our computers and all seems to be the same. With one of computers we were able at same point (when we first start running Mach3) to have the motors turning one step, but would then not move any more. We are totally frustrated, as we know the machine works fine, but we haven't been able to get it working with one of our computers. As anyone else experience the same issues?
