Thanks for appreciating my efforts. I have yet to program the button x/2, y/2 and z/2. What they'll do is make the x, y and z dro to half of their value. This function is very handy for centering a workpiece. You touch on one side, zero that dro, touch the other side and hit the 1/2 button. You get the center for that axis. I'll put codes for these buttons and upload the screen files again.
