I’ve found a reasonably priced solution
that
will be available inside two months, designed to work with any corded
track.

It is made just down the road from me. In
standard
form it doesn’t do what I want, but it is made by a small engineering
firm. Currently it recognises end stops by an increase in load on the
motor,
but he is working on a new version in which you can program the number of
turns
stop-stop. When he does this, he will produce a second version of the pic
controller which will work with either an appliance module or an SPST relay
or
any other contact closure device for discrete control.
It sells for around £180, and once the new
version is
available he’s going to let me have one on a sale or return
basis.
I’ll follow up with details once I’ve
seen it, I think he’ll be interested in talking to Mike and Li about
retail opportunities too….
