New UM3 Y-Axis noise/creaking only while extruding

New UM3. Prints are fine. Diagnostic X/Y Axes Stress tests make no noise.

I also sure there are no loose pulley / gaps.

When printing and performing Y-axis motion I hear what sounds like a cyclical groaning/creaking from the extruder/print head area. X-axis is silent. This only occurs when extruding.

This is my first Ultimaker. I've built and tuned a Prusa i3 MK2S quite extensively.

The real puzzling part is that this only occurs while extruding - and is clearly isolated to the Y-axis. I've made sure there is lubrication.

This also happens for both/either print cores.

I'm reluctant to open up the print head unit yet since this is a brand new unit. But I'm completely stumped.

I've attached a video which demonstrates the sound (and that it is only Y-axis).https://www.youtube.com/watch?v=6CS07pzpnT0

Cheers,

August

    That sounds like the Z calibration adjustment. Try to do a manual bed calibration and see if the sound disappears.

    When the Z auto stuff is at worka, the Z is changing to compensate the bed level.

    Ofc maybe is something else, but I think that noise is just the noisy stepper chips.

    agree, it is the active leveling, continuously raising and lowering the bed during print. The fact that you only hear it when the printhead is moving in Y direction means the bed is level in X direction, and not in Y.

    You nailed it. Makes complete sense. Would be nice if the auto-leveling report if bed leveling needs some adjustment. I suppose this could cause more alarm than anything else; but for those who like their machines running silently, this would be nice to learn up front.

    I went through the manual/auto leveling a few times to actually get everything dialed in. I ended up using new and totally flat of sheet 1500 grit sand paper instead of the laminated calibration card to get consistent results. I found it easier to find just the right level where I felt a tug. The laminated card slipped around more readily than the sandpaper.

    Everything seems to be running smoothly now.

    Thanks again!
