Printrbot timelapse printing a full extruder

Below is a time-lapse video of my Printrbot printing a full set of parts for a replacement extruder. The full print was 3 hours and this has been condensed down to under 2 minutes (100x speed or thereabouts).

To buy a copy of this extruder please go to my ebay listings:

Z Wobble in my prints!

I've had my Printrbot for a few weeks now and I've been having more and more success with calibrating it and getting reliable prints. I'm now at a point where I can happily leave it printing unattended and most nights I leave a full plate of parts / toys printing away and pick them up in the morning.

I still have a few issues with Z wobble which I should be able to fix. I think the threaded rods are attached to the Z motors at a very slight angle. As can be seen at the top of the picture below this causes a repeating 'wobble' pattern going up my prints:

So far though no one else has noticed this on my prints - but I want them to be as good as possible so I'll be tinkering away tonight!!
