Does Greg buy shim stock or make the spacers himself?
OK, got it Greg. Outside versus Captured now makes sense. The variable that was making it confusing was I had protected the sides. They didn’t behave as they should have.
Greg, I attached a text file with two pictures. One shows tenons on top/bottom of carcass side, the other shows tenons on the ends of the shelves. Sometimes it does it one way, sometimes the other.
When the tenons are on the carcass sides instead of the shelves, the CNC can’t cut both the tenons (cut from outside of carcass side) and the the holes/slots (cut from the inside of the carcass side)
