I found the answer to the B axis home problem
net test_sig axis.4.home-sw-in <= hm2_5i25.0.gpio.031.in
dose the trick!

It is possible that the index pulse might be too short to see that way.

Try instead.
In the HAL set the home switch to always-true.
setp axis.4.home-sw-in 1
In the INI set the axis to use the index for homing
[AXIS_5]
HOME_USE_INDEX = 1

This should allow you to home at full speed, as a bonus.
