Mach3 homing slave axis not squaring up

Good day gentle people.

I am building a new plasma cnc table to replace my old table.

A quick overview of the build
NVEM network controller
Closed loop stepper motors Hbs86h driver
Limit switch for all axis

A Axis is slaved to Y axis

Machine moves well and is calibrated.

Here is my problem
With homing with master limit turned OFF in general config.
When I reference all home
The y axis moves to limit switch stops and A Axis does not square up. The system appears to hang. If I activate the A Axis limit manually. It goes green in diagnostic page.
It appears that once the y axis has hit the limit switch. It is waiting for
The A limit switch
But A Axis does not move.
X Axis does not home.

If I turn on home with master in general config.
The homing works fine for all axis.
But no squaring up.

I have set the soft limits page.
On the soft limits page. A and Y axis are set the same.

I would expect that of this was wrong. They would drive in opposite direction when homed.

I have looked on many forums and tried multiple settings.
But can't seem to get this working

Any suggestions appreciated.
