Had he not posted, I would also think that since all moton between
holes was in one direction, that the backlash would have been taken
up on the first hole and from there on out, there would not be a time
difference based soley on which way the table was moving.

IIRC, it was a post on the TurboCNC list within the last year about
speeds.

The point I was making was that if you need to gain some speed, test
things in different ways.
