Topic: Walls/lines slightly wavy

Hi, I have the original Solidoodle, and recently I've been experiencing problems with my prints.
Walls are not as straight as they used to be. It looks to me like it's not printing straight lines any more. See pictures.

The red cube is an old print and is pretty good.
The white cube is from today and is not as good.
The third pictures is a test where you can see some waving on the border.

Any idea what's causing this and how I can fix it?
I've had issues with banding in the past but I think this is different.
Thanks for you help!

Looks like z-wobble.... it will show up worse if you are overextruding.

Re: Walls/lines slightly wavy

Wouldn't z-wobbling only cause problems between multiple layers? "wave.jpg" is a single layer and it has this slightly wavy pattern which I'm assuming is the cause of my problems.
Thanks.
