Ahhh - OK - RICH - is hitting home with me.

Yeah - I do see that Mach3 is extremely configurable.

No - I was not thinking about the vast array of possibilities.

OK - so I will need to learn how to configure what I want.
I am OK with learning.

I believe I can "ref all home" and not zero out the the "fixture zero" that is displayed on the screen.

My mistake, sorry. The Z zero will not change when you home.

I was thinking of how my X and Y are setup, with 0 offsets. Sorry.

No problem

I am beginning to understand the nature of Mach3 and its unique ability to be setup to suit the desires of the user.

This is amazing - but I now need to learn.
