I made my own stop with the stop rod being held by the upper piece that is clamped onto the Vee way and all that went away.

Also, it is not a great idea to use the stamped on lettering on the heads of the bolts as the stopping surface. It is bad enough to have them striking against the rough casting of the carriage, but those raised letters can easily make impressions in that CI surface and, worse yet, in the paint on it. You should have machined that lettering off and also made a proper strike plate to mount on the carriage. The two surfaces could be made very slightly convex so they would always hit each other in a central location and not on an edge.
Machining the screw head and other changes can be made easily.
The device is securely attached to the bed and does not slide. Thanks for your comment
