With all this talk about the double lasers, it leads me to ask this question. Anytime I mark or scribe a line on something to cut, I always try to cut just on the waste side of the line and not the line itself. If I didn't do that, everything I cut (if I cut exactly on the line) would come out a hair short due to the kerf generated by the blade. Keeping this in mind, if I were to line up the double laser on line itself, wouldn't the same problem occur? Shouldn't the laser be lined up to cut at the edge of the line and not on the line itself? Please tell me what I am missing.
