Sounds like the polarity on the dir inputs is wrong. Remember that the movement is from the spindle perspective.

On a typical mill with a table moving in x and y table movement to the left is X+ and table movement away from the column is Y+

I am assuming you are using DeskCNC. I am a Mach user but I think I can point you in the right direction.

Using the jog buttons, figure out which axes are moving in the wrong direction.

Go to the manual http://www.deskcnc.com/DeskCNCManual.pdf and find "Machine Axes Setup". There it tells you to set your steps per unit to a negative value for the axes that are going in the wrong direction. If the steps per unit for an axis is already negative, make it positive.

good luck!
