Phil,
I agree with you.
The one event that scared me the most was setting up a new AB 8400 retrofit. AB
improved the "G" software to go to zero after home (undocumented).The machine
was a P&W Wolverine with three spindle heads X 120" Y 50" Z 24" and 40HP. The
true thrill of Z axis trying to put the face of the spindle flat on the table
with a test bar in it will stop your heart.Z home is near the top of Z stroke,
and you define it as required. Do not assume home is zero, it is a preset value
from Zero, or it should be.(Home is where the marker pulse is)

But home should be referenced from the switch and reset with the proxy as
the index pulse. I don't see this as normal behavior. Homing against the
switch then moving to some arbitrary position defeats the purpose of having
a homing sequence. If you watch my video, "zero" is purely dependent on
where the machine is when you start the software. All of my ini settings
are zero. Between the two reference returns I show in my video, nothing
changed but the position the machine was in when the software was started.
This behavior is not present when only using the mechanical switch.
