Newbie Ref all home, autozero and reset

Hello,

I'm a newbie, using the demo version R3.043.066
I'm wiring a CNC machine limit switches.
The machine is three-axis.
The X axis with one motor
The Y axis with two motors (A slave)
The Z axis with one motor

The input signals:
X++, enabled, port 1, Pin 10, Actived low X, Emulated, HotKey 0
X--, enabled, port 1, Pin 10, Actived low X, Emulated, HotKey 0
Xhome, enabled, port 1, Pin 10, Actived low X, Emulated, HotKey 0
Y++, enabled, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Y--, enabled, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Yhome, enabled, port 1, Pin 11, Actived low X, Emulated, HotKey 0
Z++, enabled, port 1, Pin 12, Actived low X, Emulated, HotKey 0
Z--, enabled, port 1, Pin 12, Actived low X, Emulated, HotKey 0
Zhome, enabled, port 1, Pin 12, Actived low X, Emulated, HotKey 0
A++, enabled, port 1, Pin 13, Actived low X, Emulated, HotKey 0
A--, enabled, port 1, Pin 13, Actived low X, Emulated, HotKey 0
Ahome, enabled, port 1, Pin 13, Actived low X, Emulated, HotKey 0

In the diagnostic screen: I see the Input Signals current state all work fine.

Then when I click the "Ref all home" button.

...Press Reset... Emergency Mode Active...
Limit Switch Triggered


After that.

I proceeded to disable the Z++ and Z--
...and hurra, the "Ref all home" continued with the Y axis.

Then the Y axis work very well with the three signals
"Y++", "Y--" and "Y home". All signals enabled.

...and the "Ref all home" continued with the X axis.

Then the message again:

...Press Reset... Emergency Mode Active...
Limit Switch Triggered


I proceeded to disable the X++ and X--
...and hurra, the "Ref all home" continued until completion.

In the home/soft limits: I check enabled the Auto Zero in all axis.

Then the questions:

1.- Why not run the X and Z axis auto zero returning?
(M3Home and M1Home is on in diagnostics screen)

Note:
The Y axis work fine with the three signal Y++, Y-- and Yhome
and not active the Emergency Mode y run the autozero returning.

The only thing I find different is that the "Y" axis has slave "A".

2.- For safety on my machine. Like the Y axis.
I want to activate the signals Z++, Z--, X++, X--.

without triggering Emergency mode active, like the Y axis.

How to configure this?


I have thought that it is a software error Mach3

I can fix with wiring, but sought a solution with Mach3



Any case appreciate any related information.

I appreciate your time and attention.
