Hello guys,

I have found problem in ultimaker 2 while moving up the build plate the threaded rod is vibrating all along, same happens while lowering the build plate. Please take look in this video, and help to find root cause and so as to solve it.

Its not really a big issue and shouldn't effect printing at all. the 2 guides on the sides are what keeps the bed nice and flat, the lead screw just makes it go up and down. The rod might have a slight bent in it.

You could try to loosen off the stepper motor when the bed is low then tighten it back up. This might help centralize the motor which could lessen the effect.

I had this same issue until I reseated my bearings (which I also took off the threaded z nut). After that the wiggle was gone.
