I recently completed a CNC router build using 80/20 extrusion, linear guide rails and ballscrews. I am experiencing binding in the front right corner of the table on one of the Y axis motors and on the back left corner of the table on the other Y axis motor. Can someone give me ideas how to correctly determine where the binding is and how to correct it? I assume it is related to part of the table not being exactly square or the rails not being exactly parallel to each other. I am going to try to upload a piece of video that demonstrates how the binding affects one of the motors.

Disconnect the motors, and move it by hand. You should be able to feel where it is binding.
