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!

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

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! Henske
