I am printing with newly assembled 2.0 printer I got best prints for first few print jobs (for say approx 10 to 15 total hours printing)
then quality issue occurred not able to solve it.

X axis is fine, But y axis is printing with vibration I guess
One thing I noticed both axis (x and y) print in fine quality for 1st 10 (approx) layers then Y axis get disturbed then after some layers some times X axis also get disturbed.
till now I have tried the following things but not helpful till now ...

adjust flow rate and feed rate,
adjust exruder filament feeding tension bolt,
checked every bolt for properly tensed or not,
checked y axis rail vibration,
checked belts properly tensed or not,
flow from exruder is smooth or not and etc etc.






any comment / input will be helpful.


thanks in advance
