Dim3nsioneer & IRobertI,
Thanks for your suggestions!
I will try this and let you know if it solved the issue.

Hi there!
I have an issue with my UM1.
Allthough it doesn't seem critical (it doesn't affect the prints and it doesn't seem to get any worse) i still would like to find out the cause and what I should do to solve it to prevent future issues.
Here's my problem: during printing the Y-stepper motor gets a lot hotter then the X-motor. Especially during prints with slow print speed the temperature rises to a point where I can only touch the Y-motor for a few seconds before getting "burned". The X-motor also gets hot but i can keep my finger on the housing for a long time.
Also Y-movements produce a louder sound then X-movements during travel speed. This is clearly heard during bed-levelling (see video).
However, when I move the head by hand I do not hear any difference in sound and I do not feel any noticeable difference in resistance between X-movements and Y-movements. I can also not determine if the sound really originates from the motor itself.
I have calibrated the X & Y axes several times but this doesn't make any difference.
I have used some oil on the axes but this doesn't help either.
Anyone encountered this same problem before? Because I would love to find out how it can be solved!
Thanks for helping out!

Loud noise during Y-movement and hot stepper motor

Quick update:
I have decreased the power by altering the potmeter on the Y-motor stepper driver and it did the trick!
I didn't use the multi meter as recommended though.
I just removed the fancase from the electronics, rotated the potmeter slightly clockwise, moved the fancase back onto the electronicsboard and tested the sounds via a bedleveling Gcode.
I repeated this a few times until both X and Y motor sounded the same.
I am now printing in slow speed to check if the temperature issue is also fixed. Until now the Y-motor is even slightly cooler then the X-motor so I guess decreasing the stepper driver power solved all my problems. (well....regarding the Ultimaker that is!!! :smile:)
Thanks again for your help!
