But help us then - what are those things? There are numerous threads and I imagine thousands of posts about this, most of the speculative, time-wasting kind. Could you please disseminate for us what is the current best practice for achieving accurate repeatability in the absence of a known 0,0 point on the bed?

It depends on the project. Could you describe the use case you’re concerned with? I’ll give you the state of the art now (and we have lots of improvements in the hopper for later).
