Hello!
I have wanhao i3 v2 with lots of upgrades for sterdiness.
It was printing perfectly (well almost) until i started noticing ripples on X axis walls on printed parts.
Then i saw the cause - X idler bearing failed. I have replacied it with and upgrade of mine. (was thinking of it for a long time).
After upgrade is done, all is set up i started to print.
But i cant get the quality to even to normal. All sides of part come out with ripples. Especialy with 0.1 layer and 0.4 shell thikness. (nozzle is 0.4. PLA)
Tryed all temps - no difference. Tryed different PLA make - same. Yesterday cheked all places of printer tightened everything i could - still bad quality.
Strangly round objects come outr very well, but square are bad.
Examples:
