Deformed (ovalized) prints (RESOLVED)

[ALE5510]

So, trying to print the objects to test the printer a little, but the result of the circles is this is not at all nice. They are deformed (ovalized), and even the square objects are slightly elongated

Have you already tried to calibrate your printer?
In the forum it is described how to do it.

I have to try using MotorController. They also advised me to use Repetier (I can not use it but I'll learn ...).

The printer is new (mold for a week), but yesterday looking at the arm Z X seemed slightly wrong. Tonight I will take some pictures.

I solved the plate and tightening the axis belt =)

Cool,
you solved it just by tightening the belt?
Look forward to your experience sharing!

Yes!
I disassembled the plate by unscrewing the two screws in front of and behind it. at the back of the printer there is a tie-rod (a screw) of the belt, I loosened it, I pulled the belt and I tightened the screw well. when reassembling the plate, make sure that the black pin underneath the plate remains in the upper left corner of the printer, where there is the limit switch sensor.
