Hi there - I tried to implement a threaded rod drive to move a small object along it.
However, I found it to be wobbling all the way. Here's a video https://vimeo.com/73508953
to show what's going on.
Can you help me understand what's missing from my design and why it isn't just going straight up? The object eventually gets there but follows more of a wide irregular helix than a straight line.
Things I tried:
- Moving the motor around to try to center it more (barely helped)
- Using two smooth rods instead of one (didn't help as it either got stuck completely or it wobbled anyway).
- Using one nut instead of two.
Thanks for your help!
