CC controlled Quarry

I have a ComputerCraft quarry and I have been trying for the past 4 hours to fix it. I'm at a point now that the controller works but can't cycle the mining machine I built. The way the system works is with a GPS computer array to locate it then move it forward.

Here are all the files(not sure which one the error is in)

If you wanna test it out yourself then you will need to change the computer ID's in the Controller and Main Programs to match the ID's of the computers you are using.

You'll want to narrow things down a bit first. If you're unsure where your problem is, start out by sticking print statements throughout your scripts, each rigged to say something unique. This should allow you to determine the flow of things - where it might be sticking, which bits might be skipped, and so on.
