Hi Mac, it is a new machine, yes. The Haas tech did the test and said he was pretty happy with the result, though he will obviously be biased to some extent. I think it should only be around 16 microns out over 400MM, so around 6 tenths of a thou - is this reasonable?
Edit, I found this thread where the user realigned his machine on the blocks, is the mini mill different?

Just to clarify, I don't actually intend to move the bearing blocks themselves, but the X axis which sits on top of the Y axis blocks, hope this makes sense.
Thanks!
