Anyone have any good ideas on how to align the work after flipping it over? The Triforce I cut (http://fozztexx.com/CNC/IMG_3101.JPG) required me to flip it so I could recess the outer ring. Of course I didn't get it lined up quite right. I'm certain at some point I'm going to want to do double sided PCBs and it's going to be important that it aligns perfectly.
What I did was I had it drill a hole on the right side all the way through so that I when I flipped it over the hole would be in a fixed position from the left side. Then I moved the tool out to that fixed location and lowered it and moved the work over to set the hole in the right place. But since the hole was drilled wobbly it didn't line up quite right. There must be a better way where I don't have to worry about holes being perfect.
