If that isn't what you meant, swap any one stepper coils polarity, which will reverse the direction of travel without changing how axis see's the direction. I have been told that using x table and the left-right arrow keys, the right arrow should move the table to the left so that the bit is carried to the right in the workpiece. The up arrow should pull the table toward you, carrying the bit to the rear in the workpiece. Similarly the "page up" should raise the bit, and a "page down" should plunge it into the workpiece.
I am not sure if it has been said, but I have the [ key move my table CCW, and the ] key move it CW, but I have no clue what the real working machinists on this list prefer as a convention for that. Nor have I read what key pairs might be assigned to the other 5 axis's that emc can co-ordinate the moves of. This could be a Documentation improvement request unless it is already in the wiki. Not having the extra axis's, I haven't looked. But now I have, without finding a definitive answer.
