Is the full z-axis calibration actually counter-productive?
The directions for setting up your z-axis is to move the print-head to the left, make it almost touch the printbed by adjusting the left z-axis, then move it to the right and make it do the same by adjusting just the right z-axis. At this point the print-head is pretty much coplanar with the print bed, and that's where I stop, because that seems like the best one can hope for. If you follow the directions, though, from there you should then run the z-axis calibration, which raises the z-axis up until it bangs on both sides--totally negating what you did in the earlier step. That's why I don't do it.
But maybe I'm missing the point?
I don't seem to have any real problems either way, but I thought I'd ask anyway.

I believe it's counting when it moves all the way up (this is based on assumption, not evidence!)
Otherwise, yep, it would be pointless.

Vety interesting, Thank you
