Does the slicing software report any fixes or corrections, I had glitches like that caused by a model problem. About 50% of models I have downloaded have need correcting, they don't all cause print problems but I always check them with netfabb first, better than wasting time and filament

Firstly, it looks as if the layer shifting is only in one axis - could you confirm that is the case? If so, please confirm whether the shifts are in the X or Y direction. You could also try re-slicing the part after rotating 90 degrees to confirm that the slipping stays with the Ormerod's X or Y axis rather than stays on the same sides of the part.
You say that you have checked the belt tension. Have you also checked that the grub-screws holding the motor pulleys are exactly over the shaft flats and tight?
I usually print at 50mm/s or faster and do not get layer shifts anything like that big, so it is not a speed issue.

That is annoying for you. Each version of Slic3r still seems to have new bugs, and in some cases (such as this), it can take many frustrating days of testing to determine that the problem is caused by a bug in the slicer rather than a printer issue. It was the sole reason I decided to buy S3D. It's a real pity, because Slic3r would be by far the best slicing application if only the developers sorted out the bugs in a version before introducing new features (and new bugs). As it is you need to choose the version of Slic3r to use on each print based upon knowing which bugs are going to have the least effect on that particular part. Another effect is that when you cannot trust that the G-code file is correct, a genuine printer issue can easily be dismissed as being a slicer problem which means that it doesn't get fixed and you put up with substandard prints when you could easily have corrected it.
