yea I'm fast coming to the conclusion that this machine wont do for my jewellery work unless I make jewellery specifically for this kind of media IE big and chunky. http://www.mousejeweller.co.uk
I will try the print more than one to see if that solves the issue but it looks like this machine will be doing models rather than jewellery.
as for your questions. its about 20mm tall and the back of the skull is orientated to the bed...

What was the orientation of the print on the bed... ? It looks like you probably need more time for the layers to cool, before another layer gets put down on top, but it's a bit hard to tell exactly what's going on. It could be the opposite, that it's slowing down too much. It's also hard to get a sense of scale... how big is the part?
Sterelithography or SLS printers are normally better suited to the very finest detail work. Filament deposition isn't really the best technology for very fine detailed parts like small jewelry, so you'll need to take some time to learn how to get the best out of it. Layer cooling is a big challenge - you may need to print more than one thing at once, so that there's sufficient cooling time; slowing down the print only helps so much, before the head is going so slowly that it heats up the already printed plastic, and makes the problem worse. However, among similar printers, I'd say that the UM2 is probably the best choice for detailed work, as it has relatively good retraction control from what I've seen, and makes for precise prints.
Much of the art of 3D printing is learning the settings that work best. Small fine pieces are very challenging, so start with slightly larger, simpler shapes, and work your way up. Enable the full settings in Cura, and study the options, and experiment. Keep good notes about what works and what doesn't.
Eventually, for the most challenging prints you might want to switch to another slicer that offers the finest grain controls, and allows you to tweak everything. But to begin with, stick with Cura, and learn the basics.
Happy printing!! I think you'll get some great results given time... and keep posting, and we'll keep helping you get there :-)
