Just a guy here, but I hope you both have a great week, all the way up to Thursday.

What a great perspective -- let the good times roll!
Can you describe the noise? Is it a high pitch whine, or a grinding sound?
It could be loose cable/connector for the stepper motor, as that can cause all sorts of strange sounds (usually of the grinding type).
If it's more a constant high pitch sound, it's likely the motors in use since they draw a lot of current to hold position (steppers work funny that way). This can be ignored safely, or reduce the motor peak amps to the motor to quiet the whine a bit (this usually involves modifying the firmware, and can be a bit more difficult sometimes.
Good luck
Thanks for making this! Let's hope the run support keeps up.
My initial guess (having had similar layer shifts in the past) is that one of those skinny 'Y' vertical pieces with angled overhangs simply curled up a little too much (shrinking warpage) and eventually the nozzle took a path where it made contact with the raised edge and cause the motor/belt to slip until it continued in the new position.
Ways to prevent include much higher cooling for those curling points (super slow high fan), or enclosure of the entire unit to mitigate warping.
Sorry for late response, hope it helps or you solved it.
Kinda silly to think we'd get it right there first time? To learning, moving upward, and a brighter Internet.
