My little piece apparently never made adequate contact with the slotted nut, and just spun around on the surface of it.
I discussed the problem with my local machinist, and he came up with a great idea. I’m going to use a spring to pick up the slack between the drive and the nut. It looks like this:
I cleaned up the slot and the little distance piece so they fit together easily. I’m confident it’s going to work!
