I have a small laser (3W?) I can hang off my spindle and run from CAD, and yeah - that's annoying, waiting for the spindle delay when the laser comes on before it moves.
So if you're playing in POST land, might be worth investigating the adding of a dwell code after your M3 - that way you don't have to remember but it only affects spindle startup, nothing else.
