The differential gears are nothing to do with prime but to add the
traverse into the equation and also to add a rotation for a helical.
I have a diagram of one at
http://www.collection.archivist.info/hobbing.html
then you can wind the hob back along its cut traverse and it remains "in gear"

I am trying to put this in to watch the VFD modbus driver's "watchdog" pin, and
tie a pyvcp LED showing VFD is good, as per:
http://linuxcnc.org/docs/html/man/man9/watchdog.9.html
I used:
loadrt watchdog num_inputs=1
addf watchdog servo-thread
I have 2 issues:
One, it generates the following

I think that is the problem, he wants to know what the speed will be
prior to spindle start. At a guess in
I have looked at some gearing diagrams of gear hobbers and I noticed that a
'differential' gear set was included. What does that actually do? I suspect it
is for cutting prime number gears?

It is for helical gears, and is linked to the feed gears. (Also easy
to do with LinuxCNC

I thought it would be a good idea to display what the RPM setting is
before the spindle is started.
I see current_rps is right there WHILE the spindle is running.
But when I enter "S1", it's set inside LinuxCNC even before M3. I'd
like to display it in pyvcp before M3 uses it. current_rps
Replacing all the gearing that interconnects the various axes with encoders and
motors on each bit that spins.

I'm impressed. Nice work Dave.
