If you are slowing the edges of the waveform with the R/C network

with the waveform going slowly through a switching point with no
hysteresis might give hi lo hi when sampled every 40 uSec. The
software debounce will probably do a better job anyway.
I'll leave it for the minute then.
I will try very hard to rig up a step/dir servo spindle to join your
tests - it must be lonely!
It is <G>.
Have a try with that RS opto if you can, it's cheap and should work
fine.
I wish I had a fast digital scope with advanced triggering, maybe then
I could figure out what is happening :(
