So I have a strange problem. The arrow keys and drive the machine in the correct direction but the page up/page down are reversed. I tried inverting the z direction pin but that caused the z axis to run backwards when under program control.

Any ideas?

On the Z axis of a typical vertical milling machine, +Z moves the cutter upwards (this would make the part taller.) Is that the way you have it? Then, page down should move the cutter in the -Z (down) direction. It seems really odd that only the keyboard buttons would be working backwards.
have you modified a standard configs file set?

Not sure why but inverting the Z direction fixed it so it all works in the correct directions now.

Now to figure the home+minimum limit thing out....
