Strong vibrations in ball screw linear actuator - is it normal

[mbridge87]

Hey everyone. So here's a video which shows the vibration issue:

As I mention in the video there seems to be a sweet spot in terms of movement speed where the vibrations are really bad. If moving faster or slower than this sweet spot it seems to be ok. I experimented with different micro step settings a week ago and this didn't seem to make a difference, although this was before I realised there was this sweet spot and so I may test again.

The motor is hooked up to this driver, it's a 3DM2283T.

Would love to hear your thoughts.

Thanks,

I don't think that's anything to do with the stepper motor. It sounds like a mechanical resonance, to me something is loose or badly misaligned. Bent ball screw perhaps.?
