Z axis homes in the wrong direction, downwards was created by AlbertHall

I have set the Z direction so the actual machine movement matches the axis picture.
The home switch is at the top.
I have set the home location at 0
I have set travel from -70 to 0
When I attempt to home the Z axis it moves downwards (away from the home switch).

How do I fix this please?

This is a nice easy fix, change the sign of the home search velocity in the INI file.

I scratched my head on this one for over an hour, figured I did something wrong. So double thanks for the answer. BUT, someone should put this into the guide somewhere. It would seem to me that this is a common thing, especially on the Z Axis.

It is documented here.
linuxcnc.org/docs/2.7/html/config/ini-homing.html

The problem is that if you document every thing in every place you tend towards many identical manual sections...

If you haven't found it, this is the go-to page for all docs:
