Buzzing Noise on X axis

Hey all. I finally got my minion ready, but the Motor on X axis is making a loud buzzing Noise but only on lower speeds (something beyond 50mm/s). What could cause this issue? after some tests the sound only occurs between f1750 and f2250 mm/min

I have the same issue, I suspect being the rail, If I use lithium grease I can hear it, If I use ep grease (thicker) the sound goes away

Sounds like a loose screw to me.

Not yet. Ill unmount the hotend again to check for any loose screws For anyone interested. I changed the whole linear rails with better ones. The Sound remained... So I ended up unmounting Eva part by part and tested the noise with every step. Last but not least it was my sunon radial fan sadpepe
