v-minion - rattling noise

Hi! I could not figure out what is the source of this horrible rattling noise. I was thinking it is a fan shroud (was not flush with back plate), reprinted and reassembled the whole EVA - but it is still there. It feels it might be a X rail. Printer is second hand, so I don't know what is the rail quality and what happened before, but rails are RR stock ones I think. Any ideas?

Unfortunately, this could be a lot of things. If you're sure that ALL the screws are fine, i'd check the pulley and idler on the x axis, aswell as the carriage. If this is the Balls in the carriage rattling, you could re-grease them- at least a change in sound will tell you if thhat's the problem. to check if its from moving parts you could use the macro in the ratos macro channel helge did and i modified to check for resonances and thus rattling. if you get the sound only when moving distances like in your vid - try what i said

I think I found the source: it is 5015 fan shaft parallel to X, so when head moves left and right - fan blades moves too. I have GDStime dual ball bearing and not sure what to do now...

check it with the macro, so you can put your finger on the fan and see if it really is the culprit if it is, well, change it 😅

The question is change to what. Another 5015 probably will be the same. 4028 - not sure I'll be able to find 24v version, another buck converter is not an option (no space in the box anymore). @seriosha How to find this macro?

No idea what it is this time Okay, that was poorly maintained rails. Full cleanup, lubrication, reinstall - a lot less noise. Or maybe not... haha...

infill printed at 200 mm/s and 7K accel Y rail is in quite bad condition, maybe even relubrication could not help and It needs to be changed With 90° infill direction it a lot more silent, why is that?
