yes, I use "Touch Off". the other one is typically grayed out. I am
pretty sure because there is no tool selected yet.
When I make parts, I typically use one tool per g-code, I try to keep it
simple.
The CNC machines I have are pretty simple, they are Sherline machines,
in a Paxton/Patterson enclosure, (I have replaced all the steppers and
stepper controllers, power supplies etc replaced with stuff commonly
used. And there are no fancy things like tool changers or anything like
that to begin with.

There are two buttons "Touch Off" and "Tool Touch Off". You always use the same?
Jon,
I wrote a bunch of wizards for my mill and my lathe. I use one coordinate
system for the origin of the main part and a different origin for each each
wizard as it is called so that the wizard works with respect to the/an origin.
It makes the math in the wizard much simpler, especially when you are doing
something like rotating a rectangle.

I figured out the "touch off", and that it 'works' the same as homing,
functionally.
I wondered what all the different coordinate systems are for, their differnces.
(I know what a coordinat system is, mathematician here.)
This allows you to set up an offset from a main coordinate system, for instance
if you have several identical features to be machined on a part, one hunk of
G-code could machine each part and then set up the offset to machine the next
instance.
It can also be used if you have several parts mounted in a fixture, one coord
system for each part.
