Print quality degradation, advanced maintenance and overhaul

[pavelr 1]

Hi Ultimaker & Community. So, to put it simply, two of my UM3 printers' quality is not what it used to be. They have both done their fair share of heavy printing, one of them non-stop for years. They still produce nicely looking models but not as a new one out of the box. Let's talk about bringing it back to perfection, after all, motor steps do not rust. 

 

The natural though is to replace several parts, one by one, while printing the calibration cubes in between. My question is, what would be the right order - from most important to least important. 

 

I hope this list of parts to replace is complete - or sufficient to bring it back. Please add more, and advise about what's most likely causing degradation:

 

- Linear bearings LMK6 and LMKW6  (which already started making noise)

- Long belts

- Short belts

- Bowden tubes

- The nozzles

- Rod holders

Have I forgotten anything?

@Brettlee22, there is no one printer fits all. What is your budget? What materials do you need to print? What kind of prints (figurine, mechanical parts, etc?).
