Noise on fast diagonal movements - movie attached

When the printhead moves fast in a diagonal movement, there’s a noise that concerns me that something is loose or broken that shouldn’t be and to proceed with caution before a noise becomes a huge issue to fix. I was hoping someone might be able to hear and help identify before I went and pulled it off completely and took it apart to check it over.

Thank you!


You need to make maintenance to your belts, sprockets and look for abnormal motor wearing.

Clean all the sliders and apply recommended lubricant

Thanks very much. I have attached some images and also cleaned up the rods since them and put some super lube on the idler bearings where I could reach with a toothpick. It seems the sound only occurs when in a specific area on Y and X together (about 100mm from the back on Y, and in either direction left or right on X). Then the sound occurs. I have tried the same motion on X all over Y in other areas and it is consistently only in that specific region.

You can try this when lubrication and cleaning dont work

So, was bent guide, replace it soon, and thight the holder screw for this guide to avoid it to turn.
