I've recently picked up the domino 500, just a quick question I've seen lots of posts on here about calibrating the sight line to the base but can the paddles be set or are these just how they come from the factory? I haven't had a great deal of time with the tool but my surfaces are always flush but not always on the edges/sides. I'm half putting this down to user error but thought I'd chuck it out there. Hopefully this makes sense to you all. If someone could come back with some answers I'd be really gratefull as I love this tool.
