Ultimaker 2 is not printing cilinder shapes

[Francesca_T 2]

I am trying to print an easy circular calibration pieces on my Ultimaker 2 but it is printing oval shapes instead.

Can anyone give me a clue about how to solve this issue?

Any tip is very welcome. Thank you

It seems your axles are not correct aligned, but you can solve this easily. 

Check this https://ultimaker.com/en/resources/19953-aligning-the-axles for instructions. There is also a page on the UM website with pictures. It is from the UM3, but the axle alignment is the same for all UM printers.
