Re: Re: Tool change

Jon,

Actually I posted that it was the realisation (as Ray pointed out)
that EMC DID do toolchange which caused me to reflect that most
others don't...

Yep. This is what I posted...

These "could" be limit/home bits if the program knows it's in "tool
change" mode. I'm not saying it's the best way, but it can work
where 'bits' are scarce.

Yes. Exactly correct. But I wasn't talking about EMC...

Hope this helps.
