MK4 Loud noise while printing
I've printed 15 or so things since I first built my MK4, and during the last print which was a 15h long one, mid-way through it started making this horrible high-pitched noise. I'm not sure what is causing it, is it the extruder or one of the x/y axis?

Hi Skint007,
From your first post, the link for the video had formatting information surrounding it, which stopped the link displaying...
See below 
I copied the video link and deleted the formatting information, and not the link shows in your first post.
My concern is that I Don't know where the formatting information comes from, as I don't get that problem, myself...
Weird...
Similar formatting information van stop images displaying, too.
regards Joan

My MK4 just started to exhibit the exact same sound after 6 days of otherwise quiet printing!

The first quick and painless remedy to try is a little lubrication on the smooth rods.
Cheerio,

Thanks for the suggestion! My issue has been isolated to the idler lever as I can reproduce the issue by manually moving the E-axis with filament loaded and reproduce the sound.
Other users have suggested I reprint the part which I will do once I receive my PETG and textured plate. I've tried disassembling and cleaning out the bearing pockets but no success yet. The manufactured part appears to be poorly made/warped.

In case it helps anyone, the issue for me was indeed the extruder. After needing to change filaments, I tried to unload it and the filament got stuck because it had a blob on the end. I ended up continually backing out the extruder by 5mm until I had it cleared and picked out any little pieces of filament along the way.

Thanks for sharing your experience. I did the same thing last night and found no real debris in the Nextruder gear so my issue persists.
I'm glad your printer is back to normal though!
