Sorted :)

Use Job Options -> ToolChange -> "run code before tool change" box and enter

G53 G1 Z0 F1500

or

G53 G0 Z0

Works perfectly

Question...

Truing the bed surface.

In the wood forum it seems common to run a facing cut over the whole spoil-board to ensure the face is true to the tool, but what goes on when you have an aluminium bed plate??

Try and face it true, assuming you can traverse the whole plate ?

Try and shim the bed true using measuring equipment - DTI's etc.?

Something else?
