Mill atc configuration

Ah yes. Since you have already connected 'orient-pid.output' to the signal 'spindle-orient-output' with this line:

net spindle-orient-output orient-pid.output => mux2.0.in1

you need to remove the 'orient-pid.output' pin name from the line that reuses the signal name
So change this:

#net orient-pid-output orient-pid.output => wcomp.0.in

To this:

net orient-pid-output => wcomp.0.in

Maybe add all the pins of 'wcomp.0.' to the halshow so you can actually see what is going on.

If you attach your current hal file I can have a look at what you did.

Could you add the wcomp pins to the halshow watchlist you had in this post?

Otherwise we are just going around in circles.

I'm sorry, I got confused:

1. In your hal file delete this line:
net orient-pid-output => wcomp.0.in

2. then change this line:
net spindle-orient-output orient-pid.output => mux2.0.in1

To this:
net orient-pid-output orient-pid.output => wcomp.0.in => mux2.0.in1

I think you may need to scale your spindle encoder position so you get a value from 0 .. 1 per spindle revolution:

Multiply 'hm2_5i25.0.encoder.04.position' by 1/360 and feed that into 'orient-pid.feedback' and 'orint.position'

[edit]

You can use a 'scale' component for this and set the .gain to 1/360
