Mon UM2+ ext n'imprime pas rond, comment corriger le probleme?

[Daspike 0]

Bonjour à tous,Je viens d'acheter une ultimaker 2 extended + d'occasion (seulement 40h d'impression au compteur quand je l'ai reçue), c'est ma première imprimante, je suis donc débutant dans le monde de l'impression 3D.En imprimant certains tests, je me rends compte que ce qui devrait être rond est légèrement déformé.Est-ce fréquent? Quelles peuvent-être les causes de ce type de problème?Comment faire pour corriger ça?Merci d'avance pour le retour.https://drive.google.com/open?id=0B5chN_8j9q-temlQZ2JSQVpLMTg

A ce point, non, c'est pas fréquent.

It's very difficult to tell anything from your picture because we don't know what we are looking at. Maybe you could add a few info:

1/ What material were you using? At what temperature? What brand?

2/ Did you level the bed?

3/ Can you give us your print set-up.

4/ Since you bought this machine used, did you make sure you have the latest firmware update?

5/ Inspect the printer and make sure that all the screws are tight, especially the one holding the stepper motors. Lubricate the machine with oil, sewing machine oil works very well.

6/ You need to make a test. print circles, maybe 2 mm high and 50mm diameter?, print one in the middle and 1 on each corners. take a picture and post it.
