This is what worked: using ddt to spot a change in the tooth count,
then resetting the encoder and latching a new offset into the step

The spindles are linked in HAL, not on G-Code. This means that they
keep synch even when there is no program running.

Yes, that ought to work too (though I would prefer that the gear
didn't move at all when the tooth count was altered).
I was all set to do it this way, t

One annoyance with my hobbing config is that if I change the tooth
count the gear chuck drives itself to to the new correct position. So
if I cut a 12 tooth gear, which takes 200 gear revolutions, then
decide to cut a 120 tooth gear, when I change the textbox the chuck
sets off to do 2000 revolutio
