Excuse my ignorance. The G Code selects a tool by #. The operator has placed

Now here I guess it gets interesting. Most efficient would be if the G-Code
Parser read ahead and signaled the tool changer object that it will need tool #
Y next. The tool changer moves and loads the tool into the other side of the
swing arm. The carousel then moves back to the position X which is the tool
currently in use.
Am I missing something?
Yes, the G-code definition is that the PROGRAMMER calls for
the next tool to be prepped by placing a T## command where
he decides it should be. The problem with read ahead is,
how FAR do you read ahead looking for the T## command? It
might be a LONG way down the file.
LinuxCNC just conforms to the way a bunch of other systems
define it.
