Anyway today I finally got time to look into the issue and after disassembling the frame, removing the x-carriage (that is the cross bar that the extruder assembly/hot end travels along and moves up and down), I thoroughly cleaned everything to remove any build up of dust or greasy substances.  Then set about adjusting the frame.  It turns out that someone (not me I hasten to add) had leant on it once too often and had caused the uprights of the frame to twist slightly out of alignment.  So I adjusted them back to true, adjusted the offset of the two ends of the x-carriage and generally tidied everything up.  Once all tightened and re-assembled, bed re-levelled etc... I set about producing a test print, I went for a small vase in 'vase' mode (basically it lays down a constant stream of plastic as it circles round the design) as this is the quickest way to test for accurate vertical movement and even extrusion. 

This is the result a perfect little vase (about 6 inches tall);



Now back to my prototype Rebecca Thomas Mini
