Thanks TDahl.
I was able to solve the problem by realigning my objects on an axis. Translation seems to align to axes so after aligning the objects on the axis the end point coincides to what I need. I’ll also try the hovering trick to see if I can get that to work.
But then my original spring compression somehow disappeared in the process! The Clips are still on the timeline but it doesn’t function. Fortunately the auto backup file of SU still has the spring animation intact. So I should be able to put the pieces together.
