Print problem

Fellow reprappers,

I am having some strange issues with my Prusa i3.
When i print it seems that every layer is placed on a different location (like if i moved my object during the print).
In other words he doesn't put the layers on top of another.
Sometimes it goes fine for a few layers and then it goes wrong.
My printer worked fine before and haven't changed anything.

Someone who knows the issue?

Something like [reprap.org] ??

Not that extreme, and it only happens after 3-4 layers.
And i didn't change my stepper drivers so i dont see why they would suddenly be overpowerd?

If the symptom you are describing is close to what is pictured, perhaps one of the other causes (mechanical?) might provide you with ideas towards a solution.

If it's moving layers it is under powered.
And if you can't compromise to increase power try acceleration control [may need to be quite aggressive if you are choosing this option only]
