Hi G,

It looks slightly overcomplicated. I use KISS design techniques (Keep It Sodding Simple). It is a lesson I learnt when revisiting circuits I made some years ago. Mind you it could be dementia galloping in , or were they circuits I drew up yesterday ?

I have had quick look and don't see why you have to put relays into the home and limits circuit. It only makes more to go wrong and a relay introduces a time delay which could vary if your relay goes sticky. This will put your home positions as a variable rather than fixed reference point.

Also, when you hit a limit you need to have an override switch to be able to jog off the switch.


The buzzer reminds you to reset the override.

6Pst relay - you can get 'em, but at an ouch price. you could do the same job with DP relays, just use the latching one to control the others, and you can have as many as you need.

Cheers,

Rob

There may be other problems, but I will leave those to the forum.
