The fixtures to hold the wood and turn it over to do both sides are made and working well for when I run the router manually.
I have blocks of scraps ready to go in the fixtures for when I have it ready for a test run. Getting the back portion of the stock shaped fairly close will start saving me time compared to how I make these currently.
The block now is to get the shape in 3d and fairly close in size and shape, then on to cut3D.
My understanding of the Moi, then to cut 3D for editing and then on the Mach3 for guiding the machine is like yours. But I have no first hand experience with these programs-or much on basic file save and move steps.
