problems with walls, they look like waves

Hi,

I have this problem, i recenly changed from sprinter to marlin firmware, and i started to had this problem! (Attached pic)

I tried changing the accels, velocity and other things, and it improved a bit, but as you can see, that is not a good print.

Had someone this kind of problems?, i hope is a firmware problem, cause if i install sprinter, it look better,

Any help would be good thanks in advantaje!
