I noticed that my Ender 5 is picking up a rather extraordinary amount of fine gray dust, especially around the X and Y axis idler wheels. I'm not sure why. It seems to be something peculiar to the printer; filament dust perhaps? Don't know.
Anyhoo, I decided it was time to vacuum the beast. And, since I was going to vacuum, I thought I might as well check the bolts and belts for tightness. I'm glad I did. It seems that every bolt that doesn't have a lock washer was just a little bit loose, and the belts didn't have that guitar string sound. So I tightened all the bolts, used the eccentric nuts to adjust the idler wheels, and use a thin screwdriver to gently pry the belt end pulleys away from the 2020 rails, then tightened the bolts down, after ensuring I had that sound.
One reason I decided to check the fit & finish of the printer is that I've noticed an ever so slight shifting in the layers as the height of the print grows. It's not much, but the walls are not perfectly smooth & even all the way up. It doesn't really matter for the stuff I'm doing, since it's not for show, but I think it was a good idea to giver the Ender a little TLC.
All to say, don't neglect maintenance on your printer(s).
