By the way, the directions of Z travel assume that Z 0 in absolute machine WCS is at the level of the tool change umbrella, so movement will be more negative towards the table.
Thus, given I have a G53 Z0 to get to a safe Z, this may not be the case if some home to the table and thus Z0 in machine WCS is at the table.
Unlikely but worth mentioning subject to how ones machine is set up...
