The second Y was moving but because it was using the pulse train from the original setup it was tracking with the other motor. So if that motor didn't see its switch first the second Y would crash the switch. It was probably seeing its own switch but that was not controlling what was going to the motor. > I think that the problem is that you have y2-step in the Joint3 > section, but in the area where you are connecting the parallel port > pins, both sets of step/dir outputs are netted to the ystep.

I now have a nice .odt file that describes how to do the setup edit by edit and includes the before and after .ini and .hal files as an example. Anyplace in particular that I should store it.
