UM2 making a screeching noise on Y axis

Recommended Posts

Posted · UM2 making a screeching noise on Y axis

I just unboxed this and as far as I can tell this noise that is being produced as the head travels on the Y axis (at least Y as it correlates to Cura) seems unnatural and I am worried it is effecting the print negatively. What noise am I talking about? The one that sounds like scratching your nails on a blackboard or screeching metal on glass. That's the one! :) I can't seem to get any good results as of yet. I have mirrored the settings using the same PLA printing the same model as others have with far less impressive results. Any thoughts from the community would be appreciated greatly! Oh I did oil the rails with sewing oil and that has not helped.



Hi I posted a video of it here so you can hear it yourself. https://www.youtube.com/watch?v=fDrl-eQmqbM&feature=youtu.be

    It sounds annoying as hell.

    With power off, or with power on but with servo power off (they are off most of the time when not printing) push the head around. Try to duplicate the noise and see where it's coming from. Belts? Rods? Pulley slipping and grinding a rod? Motor? Motor pulley?

    Try also pushing it around by pushing on the side blocks or just one block and try pushing by moving the long belts or short belt directly.

    Are you near the huntington beach in CA? It's important to know what country you are in as customer support is usually faster in USA (at this time, UM CS is hiring).

    I had the same issue with mine a week after I received it.

    It got to the point I was unable to print. I then decided to inspect the stepper motors. There was dirt/debris in-between the outer housing and the stepper motor. I removed the motor and cleaned the area. When I did this, I also happened to notice some issues with the stepper motor with debris effecting it also. I cleaned everything I could. Reattached everything and sound was gone! It also drastically improved print quality, and I have yet to have any issues in the last 6 months.

    Looking at the housing image below, you can see there is very little room between the rotation and the cover. If there is dirt in there at all it causes vibration in the housing :( It would be nice to ventilate or have a cleaning hole with protection cover.

    I got my UM2 last night. After a couple hours printing it started making a noise just like this. That motor pulley was too far out and scratching the plastic just like that photo. The pulley set screw was too loose, and only took a small force to remove. I slid the pulley in most of the way and resolved the issue.

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura 5.3.0-Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
