Compensation of axis deviation

Hi everyone, i am trying to correct the typical y axis misalignment respect to x axis. I am currently using a linear equation, it looks like it´s working but when I jog the y axis it makes a joint movement and displays the deviation on the sceen. How can i do the jogging of y axis with the compensation so the axis display keeps the x at it´s position? Thanks!

Have a look at "millkins" on the Wiki
