This is off the top of my head, so double checking is preferable:
loadrt and2
addf and2.0 servo period

net input_from_probe             and2.0.in1 paraport.0.in-9
net input_from_something_else    and2.0.in2 from_wehre_the_signal_comes
net output_signal_from_and2      and2.0.out probe-in
The names with _ on the left side can be any name you like to make it easier to follow, the name with _ on the right side must be an existing signal like "probing is active" or something like that.

Debug file information:
Note: Using POSIX realtime
HAL: ERROR: thread 'base-thread' not found
./custom.hal:5: addf failed
From your error report, on line 5 you are trying to add something to base-thread, and base-thread does not exist on Mesa configs as there is no need for it.
Probably changing that add to servo-thread will work, although also probably should be servo-period, not servo-thread.

I'll post up my hal component this weekend for tool measuring and probing etc. It has a spindle enabled block function, i also have a bouncy switch probe.

Cheers Tommy - servo-thread worked:

loadrt debounce cfg=1
addf debounce.0 servo-thread
setp debounce.0.delay 100
unlinkp motion.probe-input
net probe-in debounce.0.0.in
net probe-filt debounce.0.0.out => motion.probe-input


Just repeating the probing op, so far so good.

Thanks again.

Wal.
