I've had a belly full of layer shifting and weird rotation problems.

The last bout of problems almost pushed me over the edge!!!

I have finally got to the bottom of the problem. The bearings had dried up!

Gave them a good oiling and its back to better than ever!

The polymer bearing are becoming popular with bed slingers. I've got them on my recently built P3Steel, but will most likely get them on my redesigned Ormerods if I can get past some wobbly issues!
