Grinding Noise during Travel on UM2+ in Ultimaker 3D printers Posted March 6, 2018 3 hours ago, russlang said: I also have an Ultimaker 2 Extended which has started making a horrible grinding noise in both the X and Y directions. I just replace the linear bearings in the head but that didnt fix it. I'm pretty sure nothing is rubbing. It sounds like its coming from both the X and Y stepper motors. Here's a video of the sound. Does anyone have any ideas? https://www.dropbox.com/s/ugs2271ds1rji0u/20180306_103045.mp4?dl=0 My Ultimaker 2 made a very similar noise last night! Is the filament grinding? Check by the feeder for filament...or remove the filament and check for worn spots. Or...and @SandervG mentioned this on Facebook, you could have a clogged pulley, making it rough for the belt teeth to get in there. I have to check mine tonight. I never heard this before...last night I tried my first spiralize (vase mode) and I thought it might be something going on with the Z. Another thought...what version of Cura? I'm using the latest...so wondering, however remotely, if that is a factor?
