Just looking for some advice on a stepper unit that sticks. I took it apart and cleaned and re-lube it. Worked smoothly until I put it all back together. How tight do the shoulder bolt and other screw need to be? I imagine that these two points is why it's sticking. It will advance once, and then sticks on the 2nd and 3rd position then the rest are fine.
(The pictures are the before photos of the unit).
Thanks for any pointers and help!
