Here's the Homing section of my .ini file:
HOME_SEARCH_VEL = -1.0
HOME_LATCH_VEL = 0.1
HOME_USE_INDEX = NO
HOME_IGNORE_LIMITS = NO
HOME_IS_SHARED = NO
HOME_OFFSET = 0.0

Oh, I thought HOME_IS_SHARED meant the home was shared with another axis.
I'll give that a try.

Well, you could be right :)
Always listen to the manual, or the actual behavior, better than you
listen to me.

Is it possible the state of the home switch is tripped and the machine is
backing off the switch from the start?

No, same problem.
With HOME_IGNORE_LIMITS = YES, it sails right past the home/limit
switch and hits the hard stop.
With HOME_IGNORE_LIMITS = NO, it stops at the limit, complaining that
it hit a limit in homing state 5.
HOME_IS_SHARED seems to have no effect on this.
Note: I tried monitoring
No,I manually move it away from the switch before I start.

Thanks Steve.
I made 3 halmeters as you suggested. They all register FALSE, even
when the GUI is
showing the position in red when I hit the limit.
Just to make sure halmeter is working, I added another halmeter on
axis.0.motor-pos-fb and it showed the same position as the GUI does,
updating

That's mighty odd, and more or less impossible if the HAL setup is as we
think it is. Can you add another halmeter on
is your debounce connected to a thread?

Halscope might show if there is a wierd transient effect.

Are you sure that you have the limits
Indeed, that was the problem.
Now, the halmeters show the limit switch as expected, as well as the home
signal.
The homing sequence works correctly.
(I changed HOME_IGNORE_LIMITS to YES, and it does the expected thing).
Thanks everyone for your help and suggestions.
