I had the same belt slipping problem with my ATI belt clamps. I think it was because they were from the previous run, and made for holding two ends, back before the belts were continuous. I cut two one inch pieces of some spare belting I had left over from my ShapeOko build and added them to the clamps, and the slipping was fixed.
