Need Help with ATC

I'm on the last leg of my retrofit and desperately need some help my with tool change procedure. I'm completely lost right now!
Where I am at:
Spindle is connected to a 7i77. I have control over my spindle using M3, M4, and M5 in the MDI (my commanded speed does not match actual speed - problem right now?) and I can see the feedback from my spindle encoder in HAL Meter (1 physical revolution CW = 1 positive rev count in HAL Meter).
My tool changer is an 18-pocket carousel that moves down/up and forward/backward with pneumatics. It has a home sensor and a position index signal. By using halcmd in Hal Configuration, I can "manually" walk through all the steps of a tool change procedure EXCEPT the spindle orient step.
Where I need to be:
I (assume) I need to be able to home the spindle and then index it to an appropriate angle for my carousel-style tool changer. I need to be able to do this as part of a tool change procedure called by M6 TXX
Looking through my HAL and INI files, I see nothing related to spindle orientation. Firstly, I know I am missing information to allow me to orient, and then secondly I see two ways of doing the tool change: remapping M6 to gcode moves or classic ladder. I am open to either, I just need to get this to work!!
Below are my HAL and INI files. There are a couple signals in the HAL file that I used to have available, but I needed to replace the factory-original VFD with a new model and I lost them (noted below).

When I look at the spindle.hal that is part of andy_pugh's VMC_toolchange config I see a lot of code that I am missing. I'm certain I need some of this, but I'm not clear about what I need exactly and how to incorporate it. Surely it is not as simple as adding HALFILE = spindle.hal in my INI file, right
Once I can orient, then I can start thinking about the actual tool change procedure and I will need help here as well.
Thank you for reading and ANY help you can provide!
For reference, here is andy's spindle.hal:

When I look at the spindle.hal that is part of andy_pugh's VMC_toolchange config I see a lot of code that I am missing. I'm certain I need some of this, but I'm not clear about what I need exactly and how to incorporate it. Surely it is not as simple as adding HALFILE = spindle.hal in my INI file, right
Once I can orient, then I can start thinking about the actual tool change procedure and I will need help here as well.
Thank you for reading and ANY help you can provide!
For reference, here is andy's spindle.hal:

I have been able to incorporate the logic from the VMC_toolchange sample config to allow me to select either Position or Velocity mode but I am having trouble enabling the spindle-enable command.
Because I have the velocity-mode signal connected to motion.spindle-on I don't seem to be able to drive hm2_5i25.0.7i77.0.1.spinena with motion.spindle-on (through the spindle-enable signal that is standard).
I've racked my brain over and over but I can't come up with a solution - advice?
To keep progressing, I started my config using the .hal below and used halcmd to sets spindle-enable true. This gave me signal on analogout5 in both modes (success) but only resulted in movement when I was in velocity mode.
So once I can get the spindle enabled in both modes, then I need to:
1) determine why there is no motion in orient mode
2) scale the spindle speed correctly
The two might be related? I found a diagram that shows a similar logic setup for position vs. velocity mode that incorporates some scaling but I haven't fully digested it yet. It seems to be setup differently than how I have it now (where 1 spindle revolution = +1 encoder position).
spindle hal section below. It's been cleaned up, I left my attempt at using an or2 component to flip the spindle-enable but, again, I run into the issue of the pins already being in use.
Current spindle PID section for reference. Just playing with numbers right now to see if they affected the motion:

Hi Tyler,
It seems you have a hal connection problem. If you use a custom hal component, i think you can solve your issue.
linuxcnc.org/docs/html/hal/components.html
If your problem cannot be solved, i can write a hal component wich connect your signals.
Because I have the velocity-mode signal connected to motion.spindle-on I don't seem to be able to drive hm2_5i25.0.7i77.0.1.spinena with motion.spindle-on (through the spindle-enable signal that is standard).

I have tried to use an or2 component but I can't seem to get around driving the same pin twice. There must be a way to setup the singles so that spindle-enable is active in both orient and velocity modes but I can't figure it out.

Alright! I finally figured out the logic needed to enable the spindle in both velocity and position modes. Moving the or2 inputs did the trick - seems obvious now but I stared at this code for hours today.
When I run an M19 code I get VERY SLIGHT movement of the spindle (probably less than 1 degree) and the spindle softly resists my attempts to move it by hand. My VFD is running in closed-loop vector mode as well.
The issue now may be scaling? Should I be setting a different scale factor for the position? Right now my encoder position is scaled so that 1 revolution = 1 spindle-rev.

Reworked my HAL and now my spindle is now moving under an M19 command, which is good. It seems now I need to tune the PID. So far I get either zero movement or the spindle overshoots the commanded position by several revolutions.
Any suggestions or pointers to make the tuning as straightforward as possible are very welcome

As it stands, I can't accurately lock into the targeted position because the spindle seems to always overshoot the target angle and in the process satisfy the test for is-oriented. That ends the orient command and the spindle just drifts to a stop in an arbitrary position.
How can I approach giving the PID enough time to lock into a position and completely stop the spindle? The orient component needs to stay enabled longer - perhaps adjusting the edge.n.time-left-ns pin? Should I upgrade LinuxCNC to 2.8+ for new orient pins? Open to suggestions!!
