General Maintenance
Time and usage wears on machines and they do go "out of tune". The MK3S machines are no exception, but sometimes you don't think of it and then you notice the machines are running a bit noisy and not quite the print quality they used to have.. Spent the last 24 hours taking apart, cleaning, re-greasing, tightening and re-calibrating them all and my printers are once again making their out-of-the-box music and printing beautifully.. damn these machines are good..

Outside of a little live drift, I have yet to experience this.

After how many hours of printing did you see this, Gary?
RE: General Maintenance
The oldest, 2 MK3 machines, date back to May of 2017.. didn't track the hours, probably should, both were upgraded to MK3S. They had perhaps more than a thousand hour of usage on each, maybe more, lots of long prints on both. The newest was March this year, did that one too as my original build probably wasn't perfect, the trapezoidal nuts were probably a bit too tight, and not perfectly level, and the x axis belt was now a bit loose, it seemed to be getting louder with the occasional "crash detected", it is purring now.. Actually had 2 recent machines starting to complain about "crash detected". They would stop and restart where they left off, the only sign was usually a zit or two. Maybe both had subtle build errors, machine good enough to pass check but gradually deteriorating. In either case, build error or usage, I think it is always a good idea to keep the machines clean, greased, and calibrated ..
