Random question for the group,

Random question for the group, I apologize in advance if this exact question has been asked. Has anyone seen anything similar to the weird steps I’m getting. This is a new problem and I can’t seem to get it to stop.

Any help would be appriciated.

Z wobble maybe?

That’s what I’m thinking. Maybe Z bearings getting worn.

Awesome article. Thank you.

Do the bands match up with the pitch of your threaded rod/acme rod?
