To see signals in real time, read up on halscope, Linuxcnc's own software Oscilloscope. Very powerful, I only just started to use it.
OK, here comes HALSCOPE for encoder 04 with A/B and Index
Looks like there is a Index pulse. So what can be wrong here?

moton.spindle-index-enable will only be set true once at the start of the G33.1 move.
Are you saying that encoder.04.counts is increasing but encoder.04.position is not increasing?
That might happen if the encoder.04.scale parameter is set to a very wrong number.

No I am not saying that, both counts/position are counting up or down
spindle revs does NOT

Is above levels OK, looks to be very low. The encoder has open collector NPN output = Omron E6C2-CWZ6C

You have
net spindle-pos hm2_7i76e.0.encoder.04.position => motion.spindle-revs
I don't see how it is possible for that not to work, unless you are not using the HAL file you think you are using.
If you add, to the HAL file, after that line:
loadusr halmeter sig spindle-pos
Then you A) Can be sure that the line is being executed (a halmeter window will pop up) and B.) You can see if the signal is receiving the value.

Nothing pops up!
Interesting,
Check the HAL files names in the [HAL] Section of the INI, make sure that the HAL file you are editing appears there.
(Are you using a separate spindle.hal file, for example?)

That would seem to imply that the hal file you are editing is not the one that you are executing. (double check your paths, file names and file locations)

setp hm2_7i76e.0.encoder.00.scale [AXIS_0] ENCODER_SCALE
Now error at above line = empty variable name
