Building a router to mill traces in PCB.  I have a gantry, which I have twin screws on the Y-axis.  One side is hooked to the Y-axis and the other side is hooked to the A-axis.  I am not quite sure how to sync these two axis to one axis command.  Can any one point me in the correct direction?  Thanks.

If the axis are exactly the same then you can slave A to Y from Config menu then Slave Axis.
