Hi Jazz,

I realise I have made what must be a schoolboy error and mixed up my axes.

I had assumed that Y axis is the largest one, running front to back if you were standing in front of the machine, but from what I can tell having read further and from your reply, this is in fact the X axis. I was further confused by the fact that Fusion360 comes set with the default of the the Y axis being 'up'.

So just for clarity... The axes are defined as if you were standing to the side of the machine and not the front and are... X for left right, Y for front to back, and Z for up and down? Is that correct? So on a rectangular machine the X would be the longest followed by the Y then the Z?

Cheers
