OK, I understand how it was done.
If the bottom left hand dot for each box was always approached in the same direction then any backlash would have been taken up in the same direction so would it really be the cause of the problem - I am not sure.
I know it does not solve this issue and I am not sure if it will be of any interest to you but there are alternative methods of producing images from dots or drill holes which produce the image one complete horizontal line at a time which would not be affected by a small amount of backlash which occurs with bi-directional working.
Although I produced this image using a laser it is essentially just a series of small holes or dots which could just as easily have been produced with a drill (although it may take considerably longer to complete due the Z axis movements).
Tweakie.
