Watched https://www.youtube.com/watch?v=iHKD4E1muoo and tried the method but few mm off. What is everyones setup for both side/flip machining?
Kevin uses 2 separate index features. The first cut is not as critical as it cuts out the entire part including the square edge he will use for the index on the second cut.
What I like to do if I can is start with one good square corner and mark it. This presumes that the same corner will be there after the first cut.
Then when I program the 2nd side, and flip the part on my machine, I use the same physical corner. i.e. If I used front-left on the first cut, then flip front to back, my 2nd setup is zeroed at back-left. If I flipped left to right, then the new zero is at front-right.
I also prefer to cut all the way through the part in one setup, rather than trying to make 2 setups match. That way, even if it’s a tiny bit off, you don’t see it. So to do Kevin’s part I would cut the area between the spokes and the outer profile all the way through in the 2nd setup.

I have used indexing pins.
You cut three or four holes on the top of your piece, cut the top, and remove the piece.
Then cut the holes again, but this time into your wasteboard. I used a piece of .5" plywood on my wasteboard. Insert dowels into the top of the piece. Flip it over and match the dowl holes into the holes on your wasteboard.
Notice the direction of the flip.

Y flip here right? What is the rectangle? Is that a placeholder as well?
Yes, it’s a Y flip.
The rectangle is for the moulding toolpath in Vectric.
This project is a Pumpkin Pie dish. The top rectangle is used as a reference for the inside of the pie dish.
The bottom is the reference for the bottom outside of the pie dish.

Nice! Saw it on their site but haven’t used the program yet. Looks 
My 80mm piece is too chunky for full cut in one go. After few more runs and iterations I am still few mm off. Added square corner to my bed, did a McFly thinking bed may need flattening, watched a lot more videos - but still no luck.
Now thinking I may just make two thinner pieces to cut out in 1 go and then glue it up. Good to practice, my walnut is still patiently waiting for me to get the test cuts just right.

I did a flip job and was off on the measurement of the width of my material by 1/64 which turned into a 1/32 shift.
If you aren’t using pins to register the piece make sure your width measurement is super accurate.

Can you share the file, and maybe a few pics of the setup for both sides?
Will upload this weekend. Haven’t mastered the 3D render yet so don’t laugh about my cutout in the center 
the two-tooling hole method is probably the best way to do this. I don’t particularly like to put holes in my waste board, I have a sacrificial piece of MDF that bolts down to the tee slots that I don’t mind putting holes in.
