Very likely. I have next to no idea what any of your HAL pins are called or how your spindle is powered.
You do know all these things, and are in a position to investigate your HAL and correct my wild guesses.
My next wild guess is that there is a miss-match between the pins you have enabling the spindle drive and the pins the spindle drive expects.
As a starting point, is your VFD configured for ON / REV or FWD / REV ?
(And is the spindle even a VFD?)
I am finding this thread _extremely_ frustrating. Could you at least start each new question with a summary of whether the previous problem is solved or not? And given that we are about 23 pages of posts in, the occasional summary of the hardware and machine status would be nice. This is not the only thread that we are all reading, and it is hard to remember which machine is which when trying to support half a dozen simultaneous build threads.

OK, error message gone BUT...
Still no M3 so something must be missing in Andys code for Spindle.

Sorry it is like this but I am a LCNC newbie, will try to improve my communication with relevant information.

Down in my shop I tested to edit HAL to
net spindle-cw motion.spindle-forward => hm2_7i76e.0.7i76.0.0.spinena
Now M3 functions but M4 does not, why is that so?
/edit
M4 output 9 works OK but nothing happens = spindle is still

What is your VFD connected to?
The 7i76E spindle outputs rather assume ON / REV wiring rather than FWD / REV wiring.
Can you set the VFD to ON / REV mode?
To clarify With ON / REV wiring forwards is
Forwards spindle: ON = TRUE, REV = FALSE
Reverse Spindle: ON = TRUE, REV = TRUE
FWD / REV wiring has:
Forwards spindle: FWD = TRUE, REV = FALSE
Reverse Spindle: FWD = FALSE, REV = TRUE
Most VFDs can be set to either mode.

Do you actually have the VFS wired according to the PDF and to the terminals named there? Your previous post suggests that you are using GPIO for fwd and rev to the VFD:
Can you confirm that you are now connected according to the PDF, and wired to the ENA and DIR outputs of the 7I76E? (and that the wiring suggested above is no longer relevant?)

I have lost track of what HAL file you are using again.
Does the relay click when you reverse the spindle?

Cannot be right because it will disable the spindle enable output and analog when not going forward
Is correct
If this does not work with your VFD, the trouble is elsewhere
