Thanks for the response.

Um. None of those!

I think I may be reinventing the wheel but it's a good learning curve.

Who is Autowiz? I suspect I need all the help I can get but now up to #4 in my sequence of trial prints. I've managed to get hair-thin lines even with a 0.4 nozzle. A picture, they say, is worth a thousand words so I hope to have something to show for my efforts maybe tomorrow.

Although there are loads of stl files on Thingiverse for 'The Royal Game of Ur' none are coloured like the original in the British Museum. That's my goal! As I said, 'fly before you learn to run'!
