Quality or bad Printer? Please help

[RudyVelasquez]

Hi friends,

I own two Prusas and one of them is giving me nothing but problems you can see the picture, i've tried default qualities and made some adjustments but unfortunately no good results, i'm thinking that is not a quality or settings problem... maybe a bad printer... frustrating... the part on the right is with the same exact model and is printing good so far.

Any recomendations?

Thanks in advance

Looks like you may have a loose belt or a bad motor

That regular ripple that you see is characteristic of a bent/poorly aligned Z axis screw, which would be why you see it on one printer but not the other.
