Thanks Bojan for stepping in, cheers....
Alistair, as B says, it's quadrature encoders and works beautifully with
the Bartels system. All reductions and counts are as I've stated in my post.
No doubts at all here, tested under the stars.
It's seriously a very good cheap system for the home dabbler with a bit
of practical , hands on ability. It is a very accurate positional system when
set up correctly...and half the fun is actually knowing how the workings
of a quite complex system work.
I'd suggest reading up a bit on the Bartels stepper (or servo) system to see
how versatile it really is.
