I've had mine get in an awful mess, and sometimes I can tell it's starting to go if I hear the extruder chugging as it cant feed as fast as it wants to.

Room temp was 80 F... normally 70 F.  Last time it happened to me it was when we were visiting my parents and showing the printer off.  They are just cheap with AC and it was equally roasty toasty.  They live in a dessert.  Anyhow... I meticulously align my belts, grease my bearing rods, etc.... on a regular basis. I'm a bit of a calibration fiend because of my machining experience.  Metal is less forgiving;) anyhow when night came I opened all the windows, fans at the door of my office which happens to lead to the outside, and cooled everything down.  Printed flawlessly the first time after that:)

But this may not be your problem. belt tension, poor alignment, filament hangups, etc... etc... can all cause similair problems.   

I just chalk it up as a solidoodle "date night" where I get to know my Solidoodle on that much more of an "intimate" level.... not fun sometimes, but I come out a better maker in the end... well after my frustration subsides;)

best of luck!

The printer will start printing correctly, then suddenly it will change position and mess the print.
I tried different files from thingiuniverse  like some alphabet characters (http://www.thingiverse.com/thing:15198) with the same problem.
When trying very small things like a ring it will complete the job.

So, should I first re-check the belt alignment? or what to do?

Just weird since I've run the printers for 8-12 hours at a time non stop without this issue.  But maybe it's extra hot today inside. And I just checked our room temp. 80 F... yeah I think that may be the issue. We live in a basement apartment, shared AC, landlord out of town.... no AC love today:(

Anyhow I opened the doors, put a fan on it, and we're looking good.

Thanks:)

I also bought some specialty grease to lube the rails.

It really does sound like it's binding, so follow the videos again and just make sure it's all moving easily.

Also check that the set screws in the pulleys are tight enough and they aren't slipping.

Anyhow, anybody have some ideas?  I'm out of them.
