Here's something that Art commented on that worked for me to get Z to home, followed by any other axes you choose to home simultaniously....
I used this combination....
DoButton( 24 ) "home Z"
Refcombination( 19 ) "home X and Y and B"
see notes below..I'm searching for the other "Refcombination" numbers relating to the "B" and "C" axes as I changed my slaved axes to Y and B. (edited...FOUND ..see way below)
You don't need slaved axes for this refcombination to work....

www.artofcnc.caArt also wrote this... and I found the complete "Refcombination" listing here....
"Art wrote.... The home switches, (which may be set to the same input as the limit
switches), are used only for homing. The axis will move to the switch, then
slowly move off.
The program by default does one at a time, because thats the most usual
combination. YOu CAN move any combination at once by editing the RefAll
buttons script. There is a command called RefCombination( n ) which will ref
any combination of the axi s. N is calcuated by adding the following
numbers..
X - 1
Y - 2
Z - 4
A - 8
B - 16
C - 32
So to ref X and Y togehter would be RefCombination( 3 )
