Hi Fred,

That sounds like a reasonable range for override. .01 and .001 OK, I'll
play around with those moves. I have a 25 cpr DigiKey encoder, with
detents. Doesn't feel anything line the fine 256 cpr encoder I am
playing with now. BUT, with 4X quadrature and a DRO chip, the numbers
would be useful. An earlier post commented that it's OK (even
desirable) to loose the steps when turning the knob fast, so that
movement stops when one stops turning the wheel. That would kill the
"absolute" operation of an encoder with a DRO chip, but I can see where
that might be wanted.

Best regards,

Alan KM6VV
