The HAL and INI files are on page 6.
I can upload the HAL and INI files again tomorrow evening, but there are no changes in that area. Have I selected the correct channels for logging?

The commanded and fFB position are the correct ones to monitor

You might try rehoming after the first failed home so the actual motion towards home is visible
(uses a smaller scale)

I also note that HOME_FINAL_VELOCITY is 0 which as far as I can tell is not a legal value

Why does the Z-axis then work exactly as it should?
The limit switch slowly moves onto the cam. It receives the signal.
The limit switch slowly moves away from the cam and reports that the axis is referenced.

Which value do you recommend for HOME_FINAL_VELOCITY?

Its hard to tell without a halscope plot that is scaled and timed so you can actually see the motion towards home

You might disable homing to index at least temporarily at that would simplify debugging

Are you sure there are no hardware connections that disable the drives when the home switch is reached?

Edit:

For HOME_FINAL_VELOCITY you might useĀ  a low positive number since the PID is still not tuned

Also why are the X and Y limits covering a negative range? This is standard for Z but a bit odd for X and Y
