Y Axis warp

Im attempting the first print, but after the first 2 try with the given PLA i notice a warp on the y axis creating this…

I have the Marlin V1 installed trying to update to V2.
Any thought?
This is already happened twice.
I need some suggestions…

Looks more like shifted layers than warping.
Look that your belt is tight, but not too tight, your pulley is fixed properly and the stepper drivers tuned to 0.55v.

After I installed the Marlin V2 Y axis wont move anymore…
The Belt is tight yes but there is a little margine, is not too tight.

You can see my thoughts in this post.
