Re: [CAD_CAM_EDM_DRO] Re: BOSS5 Where to plug the Geckos???

##!!! Wish I'd thought of that 10 years ago.
We had a Boxford Mill that would every now and then
decide to shut off, We even had the Boxford Engineer
in. All sorts of cards, sensors where changed but,
nobody thought to check the limit switchs other than that worked.

Sometimes it's the simple things that catch us out.
