spindle.on pin?

My HAL file references spindle.0.on, but the docs here don't mention that pin: linuxcnc.org/docs/devel/html/man/man9/spindle.9.html

That doc is new to me. Spindle is described in motion and includes the spindle-on pin
linuxcnc.org/docs/2.8/html/man/man9/motion.9.html

If you look in halshow, does the spindle-on pin exist?

I'm wondering if the component you linked to does not extend the pins to support gearbox features etc while motion publishes a default set.

My HAL file references spindle.0.on ...

this:
linuxcnc.org/docs/2.8/html/man/man9/spindle.9.html is
a hal component for spindle control/gearchanging uses and
must be loaded with a hal loadrt command in a halfile

A name collision can exist with pins provided by the motion
module (motmod) that are named 'spindle.M.*'. The motmod is
used in almost every configuration (since it controls
motion) and is specified in the ini file as:

A name collision can be avoided by using the spindle component
names= option

There is significant confusion with the duplicate naming of a generally default pin in motion. Understandably a new use like Jet who is doing the right thing by actually reading the docs should expect clarity in the documents which is clearly not the case.

Could the spindle component be renamed to avoid confusion? eg spindlegears
Alternatively could the documents be revised to provide absolute clarity?
I can't believe that a new component with a conflicting name to a standard pin name was allowed to be published.

Ahh, Les's contributions predated your multi spindle work which I think claimed the name. If you did it in 2.9, your conversion script might be able to look for the loadrt command when people upgrade. There would not be many using it..
