UM3 Z-Axis Creaking

[AJDouglas 0]

Hello all,

I have recently purchased an Ultimaker 3 and have been playing around with it for some time. All of my prints have been nearly perfect so far, so no concerns on that end. However, the z-axis does make a constant "creaking" noise while layering close to the center of the bed. I am fairly confident that this comes from the auto-bed leveling microadjusting when the nozzle is printing back and forth close to the center.

It doesn't affect print quality at all and it isn't louder than the other axes. However, I can't help but wonder if it is putting unneeded strain on the z-axis stepper motor. Does anyone have any thoughts or experience with this?

Thanks.
