Normally a CNC mill probes Z through shorting the endstop to a block of metal with a known thickness. What kind of probe will you use? Also, what kind of material will you mill?
Did you check the CNC options in advanced configuration of Marlin?
In smoothieware it says:
G30 G-code
G30 means “move the probe until it hits something in the Z axis”.
On CNC mills it can be used to :
Find where the workpiece is located in the Z dimension
Find the length of a newly inserted tool
Find the touch point between a tool and the workpiece

Thanks for the response.
I want to "Find where the workpiece is located in the Z dimension" so yes I want to move the probe until it hits something in the Z axis
I want to get little endmills and drills that have the little "collar" on the so that i will always have a known bit/tool length
What materials: PC boards, perspex and soft woods.
What probe: probably just a normal micro-switch (the type with the arm and little wheel)
I have had a look at the advanced configuration yes but have not gone into great detail just yet.
