When I'm setting up a work piece I set the tool at the default 0,0,0 location and click the Zero All button. When I move away from that location and hit the Go To Zero button the spindle goes up in the Z direction and trips the limit switch. Shouldn't it go to the 0,0,0 location that was just defined?

The spindle goes up to the defined safeZ coordinate first, you can change it's value in the configuration, look for the safeZ parameter.
This is because if there was a single movement to 0,0,0 then if your tool is at a too low location in Z and there is stuff on the table then the tool would hit that.
You can study how the gotoZero button works with opening the M204 macro with a text editor from the Profiles/Macros folder
and because the gotoZero button is fully a text macro you could even rewrite that macro if you want that button to work differently,
but I think the proper way it should work is how it is coded now.

With a home switch at the top of my Z axis I have changed the macro to move to a machine coordinate of Z-10, for those occasions where the Z zero is close enough to trigger the switch with a "safe Z" movement.

It works for me but might be a pain if you had a huge, slow moving Z..
