HURCO KMB-1 Control Update

Yes, it is the index pins that are inverted. Thanks.
net min-y <= hm2_7i92.0.encoder.03.input-index is a pin that needs inverting.
i tried with
net min-y <= hm2_7i92.0.encoder.03.input-index-not , but it errors
the other syntax my friendly AI chatbot suggests for this is:-

loadrt not count =2 (I'll just show one here)
add not.0 servo-thread
net my-input-signal-1 <= hm2_7i92.0.encoder.03.input-index
net inverted-signal-1 = not.0.in
net inverted-signal-1 => your-desired-component (which I guess is min-y)

I don't get what the connection is between inverted-signal-1 and my-input-signal-1
Or should all three lines read inverted-signal-1

Still trying to learn.

Yeah, that is not OK, should be something like
loadrt not count =2 <<<<< if you need two inverted pins, needs also another addf
addf not.0 servo-thread
addf not.1 servo-thread
net my-input-signal-1 <= hm2_7i92.0.encoder.03.input-index
net non-inverted-signal-1 = not.0.in
net inverted-signal-1 => not.0.out
net inverted-signal-1 => to whatever signal it needs to go

net my-input-signal-2 <= source of the input for inverting
net non-inverted-signal-2 = not.1.in
net inverted-signal-2 => not.1.out
net inverted-signal-2 => to whatever signal it needs to go

I still don't follow it I am disappointed in my self to say.

But, have blindly entered:- (Pasted out of the hal file)

loadrt not count=2
addf not.0 servo-thread
addf not.1 servo-thread
net my-input-signal-1 <= hm2_7i92.0.encoder.03.input-index
net non-inverted-signal-1=not.0.in XXXXX
net inverted-signal-1 => not.0.out
net inverted-signal-1 => min-y
net my-input-signal-2 <= hm2_7i92.0.encoder.04.input-index
net non-inverted-signal-2=not.1.in
net inverted-signal-2 => not.1.out
net inverted-signal-2 => max-z

This errors at the line XXXXX with net command needs a pin

loadrt not count=2
addf not.0 servo-thread
addf not.1 servo-thread
net my-input-signal-1 <= not.0.in hm2_7i92.0.encoder.03.input-index
net inverted-signal-1 => not.0.out min-y

net my-input-signal-2 <= not.1.in hm2_7i92.0.encoder.04.input-index
net inverted-signal-2 => not.1.out max-z

Two mistakes there, one mine as i forgot to tie the signals together and yours = do not add or remove stuff randomly, xxxxx does not exist as a pin or function or parameter or anything.
Is the above easier to follow?

Oh dear, I am for sure making heavy weather of this.
The revised code makes more sense in that I can kind of see the linkage now, but linuxcnc is unhappy with the net inverted-signal statement.

Pin 'min-y' does not exist

I was thinking that the point of that line was to create pin min-y

loadrt not count=2
addf not.0 servo-thread
addf not.1 servo-thread

net inverted-min-y <= not.0.in hm2_7i92.0.encoder.03.input-index
net min-y => not.0.out

net inverted-max-z <= not.1.in hm2_7i92.0.encoder.04.input-index
net max-z => not.1.out

"net" syntax is

net signal pin [pin] [pin]

if "signal" does not exist, it will be created
if "signal" does exist, the pins in the net statement will be added
to the existing pins already connected to the signal.

In this case its assumed that the signals min-y and max-z already exist and
connect to linuxcnc's joint limit and possibly home pins.
