Hi Clive, just come in from the workshop after more fun. More vids tomorrow...

Do you think it sounds like they're missing steps or is it a step-generation/processing issue? Difficult to answer without test I suppose. The quill has always made the same noise from time to time. I've was driving it with one of those crappy HY-DIV268 things and when running a repeating cycle of ten up an down movements it always returned to the same place with better than 0.01mm variation - which I was very impressed with.

I think after going to the effort of buying the highly recommended AM882 drivers, in the short term at least, I'd rather replace the motors - they only cost £27 for the pair including delivery so I can afford to replace them!

In the longer term I still favour going all-out for servos. Those Teknic Clearpath things look very impressive. If confidence in Sterling would just improve a little I'd be tempted to order.
