I'm a little bit uncertain of how to interpret your results because I may not have enough information. The more completely you can describe what you are seeing, the better I can help diagnose the problem.
It sounds like you are measuring the DIR pins between the breakout board and the drivers, a.k.a. at the output of the breakout board (and not at the breakout board input from the cable).
Correct. I put my positive probe on the DIR output terminal of the breakout board, and the negative(BLK) I grounded to the enclosure chassis.
There are two ways to connect the breakout board to each driver. In one way, the COM terminal is running at +5 volts, and the DIR output should show +5 volts in one direction and 0 volts when the axis is jogged in the other direction (with the voltage measured against ground). In the other type of hookup, the COM terminal is at ground and the DIR pin would be at +5 volts in one direction and ground in the other direction.
My breakout board is the "C10" and my drivers are "KL4030's" both from Automation Technologies(Keling).
On the x axis of the breakout board
I connected the black wire(COM) directly to DIR+ on the driver and jumpered that to PUL+
I connected the #2 pin directrly to DIR-
connected the #3 pin to PUL-
I did the same for the y (pin 4,5 and COM) and z axes(pin 6,7 and COM)
This is the way their diagram shows. http://www.automationtechnologiesinc...030WithC10.pdf

It is not clear to me whether you see the expected result on the Z axis but not on the X or Y axis, or something else.
The numbers in the x and y axes are moving.changing in Mach3 when the g-code is started but the x and y motors are not moving...only the z is moving.
If I am correct about where you are measuring, and that you see the expected behavior on Z but not on the X or Y axes, then it may not necessarily mean that you have a fault in the X and Y axis drivers. To help resolve the issue, it would be good to compare the behavior of the DIR signals at the input to the breakout board to the behavior found at the output of the breakout board. Just because some of the pins are getting through to and from the parallel port does not guarantee that all of the pins will do the same. So it's best to get as complete a description of the behavior at both the input and output of the breakout board as possible (and maybe also at the parallel port, on the other end of the cable).
I'm not sure how to do that, but I disconnected the parallel cable from the breakout board, ran the file in Mach3 and measured the voltage coming off the pins. I was getting 4.32v off pins 1,2,3 and 4. Zero volts off pins 6,7,8. 4.32v off 9,10, 11, zero off 12 and 4.32 off 13(measuring on the "wide" side of the parallel connection.
