spindle.N.speed-out-rps, speed-out-rps-abs and speed-out-abs (rpm)
also exist. This is
Motion's spindle.0.speed-out is always in RPM. Encoder outputs both 'velocity' and velocity-rpm (not sure why as scale
should get us to either unit?) so I can plug RPM into the PID (I think both the PID.command and PID.feedback should be
in the same units), but then pid.output passes through

That isn't really related to orient. I don;t know if it belongs in the
diagram, or whether it would cause confusion.

Good point. It's an SVG, so the changes can be made with a text editor and
find/replace. motion.spindle- to spindle.0.
(in most cases).
It is probably possible to pass the .svg through the regex

For instance - there is no motion.spindle-on - must be spindle.0.on
I'm going to edit this up if

I happen to be doing about the same thing - The svg is quite helpful but I
ended up with 3 questions..
In my case output of will go to a VFD -

Here is a schematic of a typical LinuxCNC spindle orient setup:
My Mazak V5 had a coarse helix cam which oriented the spindle. The one
at Galesburg used something closer to an inductive sensor to sense
index.. I think that got swapped out for an encoder. Once it picked up
the index it then rotated n counts to index the spindle for tool
change. If memory
