Issue with my prints

I am a first time poster so let me know if I am doing this wrong.

The corners of my prints have a warped appearance as seen in the image. I am not too sure what is causing this issue. Any help would be appreciated!Jan 6 2018 v2

I’m quite new to the 3D printing world so I don’t know if I’m right, but I think that you have a loose belt in one axis, so when the printer has to make a sharp turn (fast acceleration/deceleration) the belt wiggle and the axis oscillate
I hope this will help :slight_smile:
Let me know if this solve your problem.
