The above image is from your video near the end. The red arrow points to the gap between the pulley and the motor. That is huge on your machine compared to mine. That gap should be as small as possible without touching the motor. It's about 1/2 mm on mine. I suggest you remove the left back metal cover (just one screw to remove that screws directly into a threaded nut like piece welded to the cover), remove the motor, loosen the pulley on the motor and slide it closer to the motor without touching it, tighten it back up (very very tight) and then put it all back together.
I had the same issue today. During the last few days I recognized a noise in the left back of the UM2. The information of gr5 helped a lot.
I just followed the instruction above and am now back printing very silent again.
Thanks!

Thanks for all this expert feeback Gents. It has given me a great start.
It's amazing how fast the brain can go from, "Wow this is great, what the hell do I do with it"......to....."Wow this is great, now I can fix the XXXXX around the house".......really amazing tool.
I'm still playing with my test obect too. The largest one (10cm) being the most recent.........printing wise, does it look about right to you? There are some model edits I can do to certain areas to improve accuracy like under the number key pad near its "eye"........add some thickness to that bottom ledge...........
How about the upper arm. On the left of the upper arm, is a tube structure that is very nice and smooth, and next to it on other side of arm is a flat/square surface that looks quite rough........any tips for this sort of thing?
