help! Loud noise when printer trying to lift build plate???

[lukem96 0]

I just set my Ultimaker 2 to print, and when it tried to lift the build plate, it made a really loud grinding noise, the build plate didn't move any where, i just got really scared and turned it off, and came on here.

Any help will be greatly appreciated!

Hi @lukem96,

You don't happen to have a recording of the sound?

I am guessing something held down your bed and your motor was skipping steps.

It can sound intimidating, but is pretty harmless.

Is there an obstruction?

Can you manually move it up and down?

If it has the same problem our UM2 has (almost new machine) - the Z axis bearings bind\stick - the grinding sound would be the motor struggling and failing to step.
