You have 3 lines that are essentially trying to do the same thing twice.
These two lines
net spindle-index => encoder.0.phase-Z => encoder.0.phase-A
net spindle-index <= parport.0.pin-10-in
and this one line are functionally equivalent, except for the signal name.
net spindle_index parport.0.pin-10-in => encoder.0.phase-A => encoder.0.phase-Z
Here I've deleted the offending line and reconnected the original parallel port pin line.

Now no errors so I can start. But still no rpm show on screen.
I am a bit suspicious on the pulse length that Mach needs quite long pulse.
So maybe there must be some filters schmitt-trigger to make pulse suitable for LCNC.
How to measure incoming pulse width on pin 10?
Found the halscope in gmoccapy. pulsewidth 45/46 ms at low rpm of approx 200rpm

You can easily look at parport.0.pin-10-in with Halscope.
But there are some other issues.
Not sure why you added a scale component for the encoder, the encoder has a scale built in.
Try this:

Scale is in Norberts code
No difference, still same 45-46ms pulse width

Sorry, I didn't look close enough to Norbert's post.
Changing this line I think might get you there.
net spindle-velocity encoder.0.velocity => motion.spindle-speed-in
to
net spindle-rpm encoder.0.velocity => motion.spindle-speed-in
Sorry about that.

No such line in hal!
Added that line, nothing. No numbers showing real rpm yet.

I have tried to get your hal file OK.
So first I splitted it up. So in your INI you must load two hal files and one postgui hal file. Please find the modified files attached.
I did that, because this way it is easier to maintain and debug and correct.
I would recommend to split it even more so that you have one file for each part of your machine.
Please see also, that I did a little formating.
Also included the gmoccapy tool change and the tool offset connections.
Norbert
P.S. you must rename the files to fit your needs.

Thank you for the cleanup = much appreciated!
Still the problem remains = no real rpm shown.
Also M3/M4. Lathe front tooling spindle rotation shown as negative.
