After finding that my spindle encoder had drifted, and was counting
686 of the 720 counts, leading to rather unconveninally-pitched
threads, I find myself wondering if it would be sensible for the
encoder function to set a pin to counts since last index on every
index event. This could be

There are lots of ways encoder hardware can
detect problems: invalid quadrature transitions, extra or missing
counts between indexes, and maybe more. If the encoder hardware knows
pulses per rev (which is not the current scale value it knows) it can
detect missing index

I could see having that functionality as a compilable/loadable
diagnostic test so that it would not have to run all the time (ie saving
CPU cycles). I like the proposed functionality.
I actually have this test in some of my diagnostics. They set up the
encoder counter to
