Ummm, OK, but hows that going to work - which axis does it apply to?
Home and/or limit switches

This is why I think this forum is tops...there is always too many trees...you cant see all the wood, its so helpfull to have someone who can look and see the obvios.

Ok to incorperate the extra inputs you have highlighted i will have to rework the axis control, maybe an axis selector button and a plus minus button..

Thanks Irving.
