Andy thanks, I never did get a result there. I don't know how you can find threads like that. I can't and I raised the thread! I did spend a lot of time working through your second suggestion and coded it as well as validating my maths but still did not get a result. I found the maths was not trivial for me.
Then this silly idea flashed before me one morning this week. I thought if it were possible, it would be much better than a radius pin long term but more complex. It really is hard for me, I don't really have the time to dig through the EMC folder for the week or so it needs. So by the time I get back to it I've forgotten everything I've learnt. I've spent a bit more time on it since you merged state tags. I've been waiting for that for a long time so now I have to use it! I'd be disappointed if it was considered to be just something to update GUI;s with. But having said that, if you could help me expose a radius pin, I would be very grateful.
