what do you want to happen? I assume you want some sort of interlock logic between the input pin for the release button and the output pin that unclamps the tool?

Thanks again for all the help with this!
My initial thought on interlocks was
only allow button to work when "SPINDLE-FWD" is false (I need to look into the logic of what will make this command true.) And spindle velocity near 0
Spindle FWD will be disabled if "SPINDLE-LOCKED" false
( I have direct logic to spindle drive as well as controller input for spindle lock condition)
If ( SPINDLE-FWD false & SPINDLE-VEL near 0 & TOOL-UNLOCK true)
then (RELEASE-TOOL)
I need to figure out if M5 makes the SPINDLE-FWD false also.
heading to the machine to play with is some more. Is there a way to setup the simulator setups to test this without firing the machine up like I could "force a input" to see how the control responds so I can tune on this without having the whole machine running?
Thank you again for all the help. I will get to where I can handle this and contribute more one of these days.

I tend to use LUT5 for situations where I want to compare a number of logic inputs and have a specific logic output for each state.
Have a look at sim_pin: linuxcnc.org/docs/2.7/html/man/man1/sim_pin.1.html

on the and2.0.servo-thread
can I change the "0" to any other number as long as they all match the logic string I am working on? Looks like "0" is part of my Estop logic and wont load.
Thanks!

If you
loadrt and2 count=100
then you will have and2.0, and2.2, ... and2.99
So, yes, you can use and2.1 but you have to make sure that you have an and2.1
loadrt and2 count=100

I added
loadrt near count=100
loadrt and2 count=100
It will not load like that, I looked at the AND2 page and it looks the same it gives me the error "insmod for and2 failed returned -1"
I tried with no count, with different numbers, it does not like it for some reason
loadrt near count=100

100 was a crazy example. I think that in practice most components are limited to no more than 32 instances.
Use count=2 if you only need 2 of them. Any more is a waste of memory.
Each one needs it's own addf command.

Actually I tried count=2 it didnt like it either. since I only have the one for the Estop and tool handling I figured I would just have what I needed.
It does not like any variation, could it be in another hal file that is upsetting it in this hal?
Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I do have loadrt and2 count=1 in another hal file (ppmc_load.hal) I am going to try changing it there to see if I can make it happy. I am starting to think just going to the ATC would have not been that much harder.

Did you add the addf lines to your hal file? You have to have the addf for each instance of a halcomponent you use.
(for two and2 and two near)
(for two and2 and two near)
addf and2.0 servo-thread
addf and2.1 servo-thread
addf near.0 servo-thread
addf near.1 servo-thread

I have addf for all of them except for the below. I have not touched any of the code below. But there is no addf there,
There is "loadrt and2 count=1" in my ppmc_load.hal file could this be causing the issue as the loadrt is in another hal file?
Thanks!!!! I need to search to see if I see the addf is hiding somewhere else
