I have an old lathe that I run using linuxcnc with gmoccapy as the display.
I am trying to get the speed display working but it wont start and gives the error 'pyvcp_options.hal:16: Pin 'pyvcp.spindle-speed' does not exist'
If I '#' out that line and another one that gives the error 'pyvcp_options.hal:24: Pin 'pyvcp.spindle-at-speed-led' does not exist' then it starts and works as needed but I don't have the speed displayed.
I used stepconf to create the files and am using LinuxCNC 2.9.4 [Debian 12 Bookworm PREEMPT-RT ISO]
Can anyone point in the direction of a fix please?

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?

Found the problem, as for my VFD pwmgen output has to be inverted (setp hm2_7i95.0.pwmgen.00.out0.invert_output true), after that scale started to work in right direction.

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
