I am having some trouble correctly setting my Y-Axis offset on my 4-axis X-Winder. I am told to measure from the centerline of the mandrel to the delivery head. I am told that the default is 4.625 inch. What I am not sure of is, where on the delivery head do I measure to? I have tried measuring just to the face of the steel roller, to the centerline of the roller and to the point on the roller fartheest from the mandrel centerline and, when I run my code, the roller on the delivery head seems to want to come in contact with my mandrel. I would appreciate any helpful hints. Tim.
