OK, My turn...
I have 2 machines- a home-built benchtop mill running Mach2 (see pic) and a Techno-Isel gantry wood router.
My Techno machine has a great software feature, MS Dos no less, that allows for auto tool touchoff.
Here is how it works-
1) place a board in the X-Y pivot point. This lines up to X & Y = zero.
2) place the metallic touchswitch on top of the board
3) start software touchoff process, z axis starts to drop
4) at the instant the tool touches the switch, z backs off a predetermined amount.
5) z height/position is calculated to be touchoff point - switch thickness - distance backed off

It is VERY simple, and works like clockwork, a real no-brainer.

Is there ANY way to do anything comparable with Mach software?

Thanks, Mike
