My router is set up like your picture. The only two sides I can get to are the sides you can see in your picture. So I do most of my cutting from the corner in the bottom of the picture. What I was doing was to use that corner as my 0,0. I'm old as dirt, so it takes me a little ( ok a lot ) longer to understand what's going on. It only took three pages of this thread, but I finally got it
Well I'm going out and set my 0,0 to the reference you have in red. I'm still going to do most of my cutting from the same corner, I'm just going to set my 0,0,0 on the right side of my board instead of the left. I manually set my 0,0 each time before I start cutting anyway so it really doesn't matter. Now it's going to take about 8 hours or so to go back and change all my tool paths, but I won't have to worry about it any more.
Too much LDS when I was younger I guess.
