Dont really follow what you are meaning but there are 3 options for tool change on the General Config page.
Ignore
Stop spindle wait for start
and finally
Auto
First does exactly that, it ignores any tool calls in your code.
Second will stop the spindle and wait for you to press Start and continue. I also think the M6End macro may be used in this instance.
Last will look at the M6Start macro and do whatever is in it.
