To Mechanism Experts,
I have modeled a screw and a base plate. I also built in some constraints to simulate the screw assembly motion using a cylinder, and two slot follower points following a duplicate helical datum curve on the fixed part. I also built in servos for motion into the part and out of the part at different rates.
The motion works well in the center of the curve but gets lost and fails near the ends. I placed limits at 0.1 and 0.9 along the helical datum curve as stops for the slot follower.
I am wondering what can be done to improve this motion so I can go the full usable length of the curve. I am guessing my kinetic analysis is not set correctly.

Any comments?
